Those are centrifugal type fans. As the fan spins it slings the air out of the inside of the impeller to the outside. When it does this,, air is sucked into the inside of the impeller to replace the air that left. As far as the loading, the only way I can explain it is to think of the air as water, and the fan is a water pump. Restrict the amount of water in the pump, it has less to pump so less work to do. This is why your vacuum cleaner at home speeds up when you hold your hand over the hose or it gets clogged up. Wide open the fan is completely full of air, max load on it. Restrict the air, nothing to pump, less load, so it speeds up.
I wired mine up but needs assistance to start spinning, does this mean that I need a capacitor for it? Also, will a 370/440v capacitor work if I’m using 110v? Another great, helpful video as always. Thank you!
Now I see why you have so many subscribers, you have GREAT content! I was always afraid of those motors with so many wires, and you are the first person to explain it in 5 seconds! We have a mobile auto repair shop, and I can think of a lot of ways to use this, THANKS!!
We use a large version of one of these (easily twice the size the one in the video) when remodeling rooms in our house. Position it so that it's blowing outside through an open window and all of the demolition/drywall/plaster dust is evacuated in a heartbeat.
As a Plumber/Gasfitter here in Canada I use these fans for lots of stuff. They work really good for exhausting air or circulating air around. I also use them to thaw mobile homes to blow hot air from my salamander heaters down to the back of the mobile. They even work great in a house to circulate air from my wood stove in winter or draw in cool air/exhaust hot air in the summer. Works like a charm. That thick metal tubing you have is either z vent for gas or a flexible pellet stove interior liner. Great video as usual!
This is a good tutorial I would say that covering the housing with metal mesh like chicken wire would be ideal. Maybe you never plan to have kids around but someone has to look after them they can't look after themselves.
I've toyed around with this idea for a few years now. These have great suction through the side and could easily be adapted with flexible dryer hose to suck welding fumes.
that's a capacitor run motor. cap start are black,round usually has a bleed resistor to drain the capacitance charge slowly. also keeps fom knock the beejesus outta in case you accidently touch it. bleed resistor also lengthens the capacitor and start relay contacts.
Typical color coding: Green = Ground, White = Common, Black = High speed, Blue = Medium high speed, Yellow = Medium low speed, Red = Low speed. Brown and Brown striped = Capacitor That is what I have learned. I note this because few people mention the 4 speed motor wiring.
13 years as a traffic signal technician where taped wires can be left in place for decades, literally. Scotch Super 88 was what we used for most if not all the years I was there.
Well Done ! Thank You ! I have two furnace fans I salvaged: One from 1972 furnace - One from 1995 furnace. The 1972 unit draws 15 AMPS (low speed : / and pushes air at 915 CFM The 1995 unit draws 5 AMPS (low speed : ) and pushes air at 1230 CFM Huge difference ! Think I'll put the older unit on craigslist.
this is what im trying to accomplish with my blower extractor mounted to the ceiling... However I cannot tell what the steps are for wiring the switch? It seems like you may have skipped a step..
Ummm,, "These fans are designed to run with constant restriction. So you need to recreate this when used out in the open by blocking roughly 25% of the air intake or output. If you don't restrict the airflow the motor will pull significantly higher amps than it is rated for and will overheat/burn out. If you want to be scientific you can look at the side of the motor and read the rated amps. Then with a load meter ( amzn.to/2rhGYLK ) hooked up, run it and block off the air flow until the amp draw drops to or close to the rated amps." >> Electric Motor techs usually know what they talk about..
Does this work with a 230 volt fan motor? A friend told me the 230v motor will over heat and burn the motor up when connected to 110v source. Any thoughts?
I'm personally preferring blowers from Evap Coolers as their motor can be separated from the air stream and therefore less likely to explode when sucking flammable fumes like spray paints
I wired it white to white and Black to black. Nothing happen. This one does have a capacitor on it. Could it be bad or do I have to re- wire it also? Thanks
VERY INFORMATIVE VIDEO I, 'm new at this so be patient with my question; I replaced the 1/6 th single phase motor and the furnace works up to starting the blower motorTHE MOTOR CAME WITHOUT A CAPACITOR AND ONLY A SINGLE BLACK CORD with MOLEX PINS TO PLUG INTO THE CONTROL BOX 9 PIN MOLEX CONNECTOR; MY ISSUE IS WHERE THE WIRES GO INTO THE FEMALE SIDE OF THE CONNECTOR; THE OLD MALE PIN SIDE HAD A JUMPER WIRE GOING FROM #1-- #3 SPOT TOP LEFT TO RIGHT- WITH THE SINGLE RED WIRE PLUGGINTO SPOT #4 DIRECTLY UNDER THE BLACK JUMPER WIRE OCCUPYING SPOT #1- THATS ALL-- THE WIRES ON THE BACKSIDE OF THE FEMALE CONNECTOR I HAVE 4 WIRES BOTTOM LEFT TO RIGH SPOT#6 REDT #7 BLACK SPOT#8 WHITE SPOT#9 BROWN; THIS MOLEX BLOCK IS ATTACHED TO THE INSIDE OF THE CONTROL BOX; I JUST CANNOT FIGURE OUT WHERE THE HOT WIRE GOES AND THE NEUTRAL SIDE OF THE POWER CORD GOES; HELP PLEASE!! THANK YOU,S PJP
What would cause a electric motor to turn on and then turn off after about 5 seconds. It starts up and goes real fast but then it sounds like it hums for a second and then a few seconds later it just turns off.
Question to anyone in UA-cam land that may know……. explain how a 220v blower motor can be ran off a 110v outlet? Is the 220v being divided inside the AC unit and the blower motor is only receiving 110v? I’d like to learn and understand the process how these units work. In advance, THANK YOU, for any info or links, knowledge is power and I want to learn!
Love it man! I have one in my shop too. Made an air cleaner out of it. Just in a box with furnace filters on 3 sides, rolling on casters. Love your vids!!
When I did my fan conversion, I used a clamp meter to monitor the amps drawn by the motor. I added air flow restriction until the motor was drawing its rated amperage. This was based on ua-cam.com/video/qX-GodOlUuU/v-deo.html
Yes, I've tested a bunch and found that blocking roughly 25% of the air intake gets you really close. But setting it up and adjusting the amp draw with a meter is ideal.
Great video and information. I have a large one I'm making into an air quality/cleaner blower. I do woodworking projects and I'm getting ready to start the restoration on my 56 chevy in the same shop, so clean air is important. Thanks for the wiring help.
From the factory there is always a specification decal. Lot of times it's under the brackets that hold the motor in the fan housing. It'll tell you what each wire does. It'll also tell you whether this is 120 or 240 volt motor. It'll tell you if it's single phase or three-phase. Without that or without knowing exactly what it came out of it's just a guess. The only wire that's blatantly obvious is a green or green yellow wire which is a ground. Double browns are generally for a capacitor.
So .... if i make a "casing" (restricting the side air intake) around mine, and reduce the outlet to 4-5- or 6 inches (exhaust) .. i'tll work just fine ?
Scotch tape is great EXCEPT if it gets hot! I used scotch tape for years and was always glad to have it UNTIL I left some in my non AC garage. After a desert summer when I took some tape off the roll the adhesive had stuck itself on the tape underneath and had lost all of it's stick-to-it! I still have a few rolls in the house that are just fine, but a handful of new rolls out in my garage went belly up. Just a tip for those in hotter climates.
Good to know. It's held up better to heat than any other electrical tape I've tried. On a side note I recently started using TESA 50126 wire loom tape and it is great stuff for wrapping looms. It is a fabric tape and is high heat rated for under the hood use. The fabric doesn't allow the adhesive to melt off.
That fabric loom tape sounds great. The odd thing about the 3M scotch tape is that it seems to hold up pretty well under the hood even in the desert conditions, other brands the adhesive can go all goo-ie and come off the loom. I've more that once had to remove and replace tape like that off of looms and it was a greasy mess. BUT Scotch tape *on the roll* left out in the daily 110+ temps for a summer, not so good. Another funny thing, I have a couple of dollar store rolls of tape (precious to me now) that have lasted just fine for years out in the garage. The desert is a very harsh place
Wow, I have a fairly new squirrel cage fan I kept from my old furnace when I had a new one put in. I remember thinking it would be good for something but kind of forgot about it and didnt really know what to do with it anyway. Thanks, this will be tomorrows project!
Fantastic. I finally got a minute to catch up on watching some vids. That 88tape is the same type I use. You get what you pay for and made in the USA! Crazy dog is back, yes!
He loves building these things out of wood. I commercially built and designed high end custom furniture for a decade and have a love for wood. But some things I think are better suited for metal.
my dad and grandfather got a commercial fan like that from a building that was to be demolished in the 70s. After putting bigger bearings and a chain drive on it it was used as a pto driven leaf blower on our golf course. 24" fan with a 24x18" discharge. we had 60 acres lined with woods on 3 sides and had about 250 trees on the course. lots of leaves were moved with it and my dad still uses it to clear his yard in the fall.
For North America a typical 220V motor will have 3 wires: 2 black and 1 white. The 2 black each go to a 110v leg of the 220v circuit and the white wire connects to neutral or ground.
I love those blowers. I installed one in an enclosed trailer when I needed it as a shop and it about blew me out of there. The best thing it did however was blow all the saw dust right out the back of the trailer. Great tutorial!
I've got an old 4 speed blower fan, either the motor is bad or I'm doing it wrong, I've got it hooked up to a single pole double throw on/off/on toggle switch for high and low speeds, the speeds are on load A and load B and one wire goes to the line side of the switch while the other goes to common, all the switch does is make or break the connection between either speed tap and one line wire, I'm not measuring any current flow to common when the switch is off, during my initial testing where I briefly ran the blower for less than a second on both speeds to ensure I wired it right I got a whiff of electrical smell and there was immediate heat coming from the motor windings, casing was still stone cold, didn't blow the ground fault or overcurrent protection and the motor didn't sound labored and sounded mostly normal, though the intake was completely blocked so it wasn't running completely right, motor hasn't run in at least 2 years, I don't think it's quite cooked yet given how little it was run, but if it is I can get a good used motor for free, as I know a guy who's got a literal pile of fans and motors from old furnaces he removed
I watch how you make those four holes. What tool is that? It cuts the metal fast. Also I have a question, my wood/metal/plastic scroll 16" been unused for 15 years, . I oil it and check it out. Not working!! I contact dremel company. They said no parts available since 2005. So I took it apart and the motor has 4 wires. White, yellow, red, and blue. If I want to wire it to white and black cord, to see if motor is good or not. Motherboard sitting next to it. I am not worried about the motherboard as I am not going to used them. Just the motor if it works. How do I wire them? What colors?
Thanks, I just had my HVAC replaced in my home, and they temporarily left my old furnace/blower in my attic. I'm going up there to salvage the blower now!
Hey Sixtyfiveford I'm curious I am picking up a industrial squeral cage blower today 1hp and it has a capacitor attached to it with the 2 brown wires like you said. Now it's 240v. What does the capacitor do and can I operate it without it? Thanks so much.
Great video! I have a blower that I need to wire. It has the capacitor wires (brown). Do I have to use the capacitor when I wire a switch/cord in or can I abandon the brown wires?
Ok,so would X amount of filters place in front of it provide the back pressure necessary? That way you get diffused clean air coming out of the filters and the motor gets the resistance it needs. The box fan/filter setups result in wild air currents stirring up god knows what in a dusty area you're trying to clean so eff that! What about it? Is a filter or five say in front of one of these a win win?
I just learned why my blower turned shop fan cycles off and on. The motor is getting too hot, thanks for the education. I will add just a bit of intake restriction as you demonstrated.
these fans are designed to work in a box... like you’ll find them mounted in a furnace. in a box, some air will pass through both sides, cooling the motor. run wide open (unrestricted) on the input side and restrict the discharge side. adjust the discharge while watching a clamp ammeter- metering power consumption. you will hear the speed jump up when you hit the right amount of restriction, and the amps drawn will be at a low. the fan is now balanced for performance, which will ensure a longer life. remote the capacitor to the outside of the fan cabinet for easy service- the starting capacitor should crap out long before the fan motor.
I have some small blowers I bought for around $50 each. One is a Stanley and another is a Lasko but they are essentially the same. They are great for moving air. They don't move as much as a furnace blower but we can easily keep it in our hall closet. We often take one on road trips for circulating air in the hotel room and drying swimsuits.
Informative as always. I wish I could think outside the box ( fan ) more often. lol. PaintSociety showed how to construct a cheap temporary spray booth and I think one of these might work. Maybe too powerful? I'll keep it in mind for next year's paint projects. On another note. I won a running AutoTron 3300 at auction last week for $128 ( retail $2k ). Picking up after Thanksgiving. I was shaping up to buy one of those $600+ jobbies from Amz too. Induction heater that is for rusty bolts. This 3300 model can do more than that apparently - PDR, windshield and bedliner removal. Always stay inquisitive you never know what you may learn!
It will use the exact same amount of electricity either way. Not all motors can be wired for 240volt but they all have a wiring schematic on the side that will show you which wire goes where for a 120 or 240v operation.
It seams to work very well. I had an identical unit in the same spot last year but it just shot straight down. It was great for getting the Carb cleaner, paint, etc fumes out of my face if I stood directly under. It'll be nice to be able to stand almost anywhere and have fresh air.
I got one sitting in My garage for ten years now. I'm thinking of retrofitting a furnace filter in a box (cardboard, steel, plastic, etc..) with the blower to use as an air purifier. It would clean out the air in a large room in no time flat.
I use an old swamp cooler motor and cage. Same thing ....two speed also...swamp cooler on casters its about 3" off the floor...bucket of water in it and it works for a while....til the humidity rises to the point that evaporation has saturated the air....actually works better when doors windows are open.
Hi, I have an old electric fan heater which I had to take a part to fit it in a smaller case, unfortunately I messed up the wiring!! can anyone explain how to join/ connect the power, fan motor to the 2 heating wires please? thank you very much
i love the squirrel fan. i have a massive one that really blows the air actually to much air but I'm saving that for when i move and actually have a good size shop. As always great video my friend.
I learn something everytime I watch you... the wiring was very informative ...no I know .. in Quebec Canada they had there worst flood in a hundred years so they need to ventilate so this is great
Yeah, here it is Red Blue Green, live neutral earth. Just seems strange. Oh, and light switches in the US??? Up for on? Ours are down for on. lol Still love the US... Best rock music by far!!
ok i have a very important question that i hope you can answer. that fan of yours with the dimmer switch. how do you wire that up? do you have a video showing how or could you make a video showing how?
The tape from Harbor Freight is generally no good for anything but fire starter. Even the masking tape is hump. My favorite for years was made by the Tuck Tape company. I still have an almost full roll of the original Tuck Tape, closely guarded and used sparingly. It cannot be found. I do believe that when the Tuck company went out of business, Duck Tape came on the market. Betcha they stole the name recognition.
I had a neighbor give me one and I built a stand for it. I can't use DEET everyday so I use the power of the Hawaiian Islands - a steady wind. Mosquitos can't fly in that kind of wind. I can't find a good wiring diagram for it, and would have to take the motor out to read the one glued to it. There is no blue wire, it's white, black, dark green, orange, red, and brown. I have white and dark green hooked up, and it blows good, and thanks to your info about back pressure, it no longer overheats. I have to start it by hand because it doesn't have a capacitor. BTW - if I use the black, it creates gale force winds.
Smashing fan and wiring discription :-D. With a side port ring it could be very handy in a spray booth to suck the the nasty air out of the booth, i bet that would be really effective. If you find yourself being dragged into the booth, use a lower setting ha ha :-D Dogs allways make me laugh with the water biting :-D
Generally I only use it to supply clean air to a contaminated area. However this motor could be used in a flammable area as there is no switching, contacts or brushes internally that create sparks/ignition point.
Those are centrifugal type fans. As the fan spins it slings the air out of the inside of the impeller to the outside.

Restrict the air, nothing to pump, less load, so it speeds up.
I wired mine up but needs assistance to start spinning, does this mean that I need a capacitor for it? Also, will a 370/440v capacitor work if I’m using 110v? Another great, helpful video as always. Thank you!
i have a tiny little one i picked up years ago and taped a metal tube to it, works great for livening up a fire.
Great video, very informative. Thank you. I wasn't sure about wiring and you solved my question.
My dad has been using one of these for decades so I got to grow up learning engines with them cooling me, I still think they're very cooooool.
Now I see why you have so many subscribers, you have GREAT content! I was always afraid of those motors with so many wires, and you are the first person to explain it in 5 seconds!
We have a mobile auto repair shop, and I can think of a lot of ways to use this, THANKS!!

I have a fan that has red,black,orange wire can I make it work with 110 if yes how do I wire it up
On the side of the motor there will be a wiring diagram. It will tell you if it's 240 only or if it can be wired 120. And if so which wires go where.
I had one at my last shop when I lived on the bayou. man did that thing move some air. i need to get another for this shop.
They move a lot of air.
As a Plumber/Gasfitter here in Canada I use these fans for lots of stuff. They work really good for exhausting air or circulating air around. I also use them to thaw mobile homes to blow hot air from my salamander heaters down to the back of the mobile.

Your channel is so awesome man iv seen most of your videos I'll probably end up watching all of them over time.
that gives me an idea for a welding fume extractor! thanks Moe!
I've toyed around with this idea for a few years now. These have great suction through the side and could easily be adapted with flexible dryer hose to suck welding fumes.
exactly what i was thinking
The Moto fixery. marijuana exhaust fan
that's a capacitor run motor. cap start are black,round usually has a bleed resistor to drain the capacitance charge slowly. also keeps fom knock the beejesus outta in case you accidently touch it. bleed resistor also lengthens the capacitor and start relay contacts.
Yes, the larger generally 1/3,1/2,3/4hp units are all cap run. I've seen a few cap run in the smaller hp, but most aren't.
Typical color coding: Green = Ground, White = Common, Black = High speed, Blue = Medium high speed, Yellow = Medium low speed, Red = Low speed. Brown and Brown striped = Capacitor
That is what I have learned. I note this because few people mention the 4 speed motor wiring.
13 years as a traffic signal technician where taped wires can be left in place for decades, literally. Scotch Super 88 was what we used for most if not all the years I was there.
33+ is awesome as well
Well Done !
Thank You !
I have two furnace fans I salvaged:
One from 1972 furnace - One from 1995 furnace.
The 1972 unit draws 15 AMPS (low speed : / and pushes air at 915 CFM
The 1995 unit draws 5 AMPS (low speed : ) and pushes air at 1230 CFM
Huge difference !
Think I'll put the older unit on craigslist.
i been turning these into blowers scence the late 80s.
They're handy for sure.
Dan Hughes how to i make mine run high . it only has two wires runing from the motor
I have red, blue and black. No white. There is a separate green with a yellow stripe I’m assuming is a ground. No white.
this is what im trying to accomplish with my blower extractor mounted to the ceiling... However I cannot tell what the steps are for wiring the switch? It seems like you may have skipped a step..
Nice
just got 3 of them
Didnt no none of that
Thanks for the infor👍🏽👍🏽👍🏽👍🏽
The reason it spins faster partially blocked is you take away some of the load im pretty sure
Ummm,, "These fans are designed to run with constant restriction. So you need to recreate this when used out in the open by blocking roughly 25% of the air intake or output. If you don't restrict the airflow the motor will pull significantly higher amps than it is rated for and will overheat/burn out.

i think i'm going to put one of those on the vent in my attic to suck air through in the summertime to keep the house cooler
I wired it white to white and Black to black. Nothing happen. This one does have a capacitor on it. Could it be bad or do I have to re- wire it also? Thanks
Thanks for sharing the wiring information ! Saves a lot of head scratching !
Thanks Bob.
Can you recommend a speed control switch or is it even worth the effort?
I have one I've used for years. I just saw on Facebook this evening where someone near me has a bunch of them for $10 each
I have one that won't stay on it cut off and i can hear kicks on but i have give it a push with my hand.. then it still cuts off after 5 seconds

THANK YOU,S PJP
You need to look at the data plate decal on the side of the motor. It will tell you what every single wire does.
I made one of those in 1995 and I've been using it ever since. even mounted it to a roll-around tool cart.
It's impressive how much air they can move.
That’s what you call good old fashioned American ingenuity! Great job friend.
Thanks, I'm glad you liked it.

In advance, THANK YOU, for any info or links, knowledge is power and I want to learn!
Not all motors are set up to be able too run on 120v/240v. They will say right on the side if they are. If it doesn't say, you can't do it.
Love it man! I have one in my shop too. Made an air cleaner out of it. Just in a box with furnace filters on 3 sides, rolling on casters.
Love your vids!!
Very nice. For woodwork, correct?
sixtyfiveford yes

I got one in my bedroom
Just what i was looking for. I just had my whole furnace replaced and I kept the old blower but it's 220, will it still work with a regular 110 plug?
Unfortunately no.
My second larger unit has a triple flat plug with black, yellow and brown plus a separate blue wire. These do not have diagrams on them.
From the factory there is always a specification decal. Lot of times it's under the brackets that hold the motor in the fan housing. It'll tell you what each wire does. It'll also tell you whether this is 120 or 240 volt motor. It'll tell you if it's single phase or three-phase. Without that or without knowing exactly what it came out of it's just a guess.

Awesome.
the only thing that cheap electrical tape sticks to is itself.
It even struggles at that sometimes.
and only once, after a single use its done lol
Fantastic. I finally got a minute to catch up on watching some vids. That 88tape is the same type I use. You get what you pay for and made in the USA! Crazy dog is back, yes!
Yep, Crazy dog never stops when the hose gets pulled out.
My problem is my blower doesn't have a white wire it just has red,blac,and yellow how do I connect it for a high speed if u can help me?
On the side of the motor there's a decal that tells you what every single wire does.
How would I wire it to 220v? Like a dryer plug?
Now to watch Matthias Wandel impressively make one out of wood for a new shopvac.
He loves building these things out of wood. I commercially built and designed high end custom furniture for a decade and have a love for wood. But some things I think are better suited for metal.

After putting bigger bearings and a chain drive on it it was used as a pto driven leaf blower on our golf course. 24" fan with a 24x18" discharge. we had 60 acres lined with woods on 3 sides and had about 250 trees on the course. lots of leaves were moved with it and my dad still uses it to clear his yard in the fall.
Very neat!
Thanks for the info 👍🏾👍🏾
How do you wire the motor if it is 220V?
For North America a typical 220V motor will have 3 wires: 2 black and 1 white. The 2 black each go to a 110v leg of the 220v circuit and the white wire connects to neutral or ground.
I love those blowers. I installed one in an enclosed trailer when I needed it as a shop and it about blew me out of there. The best thing it did however was blow all the saw dust right out the back of the trailer. Great tutorial!
That sounds like a great application.
I wanted to make one into a leaf blower but they're too heavy
I've got an old 4 speed blower fan, either the motor is bad or I'm doing it wrong, I've got it hooked up to a single pole double throw on/off/on toggle switch for high and low speeds, the speeds are on load A and load B and one wire goes to the line side of the switch while the other goes to common, all the switch does is make or break the connection between either speed tap and one line wire, I'm not measuring any current flow to common when the switch is off, during my initial testing where I briefly ran the blower for less than a second on both speeds to ensure I wired it right I got a whiff of electrical smell and there was immediate heat coming from the motor windings, casing was still stone cold, didn't blow the ground fault or overcurrent protection and the motor didn't sound labored and sounded mostly normal, though the intake was completely blocked so it wasn't running completely right, motor hasn't run in at least 2 years, I don't think it's quite cooked yet given how little it was run, but if it is I can get a good used motor for free, as I know a guy who's got a literal pile of fans and motors from old furnaces he removed
I watch how you make those four holes. What tool is that? It cuts the metal fast. Also I have a question, my wood/metal/plastic scroll 16" been unused for 15 years,
. I oil it and check it out. Not working!! I contact dremel company. They said no parts available since 2005. So I took it apart and the motor has 4 wires. White, yellow, red, and blue. If I want to wire it to white and black cord, to see if motor is good or not. Motherboard sitting next to it. I am not worried about the motherboard as I am not going to used them. Just the motor if it works. How do I wire them? What colors?
Thanks, I just had my HVAC replaced in my home, and they temporarily left my old furnace/blower in my attic. I'm going up there to salvage the blower now!
Anybody? Can I run a 220 blower fan on 110?
Hey Sixtyfiveford I'm curious I am picking up a industrial squeral cage blower today 1hp and it has a capacitor attached to it with the 2 brown wires like you said. Now it's 240v. What does the capacitor do and can I operate it without it? Thanks so much.
Great video! I have a blower that I need to wire. It has the capacitor wires (brown). Do I have to use the capacitor when I wire a switch/cord in or can I abandon the brown wires?
You need the capacitor. It does two things: helps the motor start and then shifts the electrical phase so the motor runs smoothly.
I have two of those, didn’t know why both only ran a couple of minutes and stopped, now I know. THANK YOU 🍻🇺🇸
Ok,so would X amount of filters place in front of it provide the back pressure necessary? That way you get diffused clean air coming out of the filters and the motor gets the resistance it needs. The box fan/filter setups result in wild air currents stirring up god knows what in a dusty area you're trying to clean so eff that! What about it? Is a filter or five say in front of one of these a win win?
And put caster's on it and use it for the inside of house
I just learned why my blower turned shop fan cycles off and on. The motor is getting too hot, thanks for the education. I will add just a bit of intake restriction as you demonstrated.
I've had to block upwards of 75% of the one side on some to keep them cool.
these fans are designed to work in a box... like you’ll find them mounted in a furnace. in a box, some air will pass through both sides, cooling the motor. run wide open (unrestricted) on the input side and restrict the discharge side. adjust the discharge while watching a clamp ammeter- metering power consumption. you will hear the speed jump up when you hit the right amount of restriction, and the amps drawn will be at a low. the fan is now balanced for performance, which will ensure a longer life. remote the capacitor to the outside of the fan cabinet for easy service- the starting capacitor should crap out long before the fan motor.
I have some small blowers I bought for around $50 each. One is a Stanley and another is a Lasko but they are essentially the same. They are great for moving air. They don't move as much as a furnace blower but we can easily keep it in our hall closet. We often take one on road trips for circulating air in the hotel room and drying swimsuits.
Those are nice units.
Informative as always.
I wish I could think outside the box ( fan ) more often. lol.
PaintSociety showed how to construct a cheap temporary spray booth and I think one of these might work.
Maybe too powerful? I'll keep it in mind for next year's paint projects.
On another note.
I won a running AutoTron 3300 at auction last week for $128 ( retail $2k ). Picking up after Thanksgiving.
I was shaping up to buy one of those $600+ jobbies from Amz too. Induction heater that is for rusty bolts.
This 3300 model can do more than that apparently - PDR, windshield and bedliner removal.
Always stay inquisitive you never know what you may learn!
I presume you wire it 220 you will use less electricity. When you do that the white wire become a hot wire am I correct?
It will use the exact same amount of electricity either way. Not all motors can be wired for 240volt but they all have a wiring schematic on the side that will show you which wire goes where for a 120 or 240v operation.
this guy is fantastic every video as so much information...
Thanks Robert. -Moe
I like the idea of putting hoses on there where you can direct the air in different ways. Seems to put out a lot of air.
It seams to work very well. I had an identical unit in the same spot last year but it just shot straight down. It was great for getting the Carb cleaner, paint, etc fumes out of my face if I stood directly under. It'll be nice to be able to stand almost anywhere and have fresh air.
Hooking them all up gives you ludicrous speed.
It goes to plaid
I have one and want to make a box for it. 20x20
You are da man. Racking my brain wondering why the blower won't work in a cooler for s..t. placed a restrictor on it and it works awesome. Thanks
I got one sitting in My garage for ten years now. I'm thinking of retrofitting a furnace filter in a box (cardboard, steel, plastic, etc..) with the blower to use as an air purifier. It would clean out the air in a large room in no time flat.
I have a motor with a capacitors, a black, an orange and a red. Which one is the neutral?
The wiring diagram is on the side of all motors.
thank you !! Patrick.P
I use an old swamp cooler motor and cage. Same thing ....two speed also...swamp cooler on casters its about 3" off the floor...bucket of water in it and it works for a while....til the humidity rises to the point that evaporation has saturated the air....actually works better when doors windows are open.
You are so freaking clever!
Thanks Amy! -Moe
The the rheostat Is brilliant
Hi, I have an old electric fan heater which I had to take a part to fit it in a smaller case, unfortunately I messed up the wiring!! can anyone explain how to join/ connect the power, fan motor to the 2 heating wires please? thank you very much
i love the squirrel fan. i have a massive one that really blows the air actually to much air but I'm saving that for when i move and actually have a good size shop. As always great video my friend.
Thanks.
I learn something everytime I watch you... the wiring was very informative ...no I know .. in Quebec Canada they had there worst flood in a hundred years so they need to ventilate so this is great
how do i hook up the capacitor to the plug?
Great info, thanks!!!
WOW Another great idea! That thing really blows....well you know what I mean LOL
Thanks Man.
I appreciate the video, but maybe add in a short clip of wiring the switch and power supply chord.
The wires is plug in to motherboard. The little thing where four wires are in and you slip them into motherboard, I can pull it out.
American wiring is weird... completely different from many places.
The plug is different, but the basic wiring should be the same from what I've seen internationally.
Yeah, here it is Red Blue Green, live neutral earth. Just seems strange. Oh, and light switches in the US??? Up for on? Ours are down for on. lol Still love the US... Best rock music by far!!
Thanks for the video. Like you said, I was intimidated by all the wires. I have two of these in my shed I want to make fans out of to use at work.
If capacitor is bad will fan move very slowly?
Yes. Generally the motor won't start spinning by itself and will just hum. If it does spin it will be slow.
ok i have a very important question that i hope you can answer. that fan of yours with the dimmer switch. how do you wire that up? do you have a video showing how or could you make a video showing how?
Good job only thing I see is maybe buy a light switch their only 2 dollars a little safer and move switch down low where you can turn it on or off
The tape from Harbor Freight is generally no good for anything but fire starter. Even the masking tape is hump. My favorite for years was made by the Tuck Tape company. I still have an almost full roll of the original Tuck Tape, closely guarded and used sparingly. It cannot be found. I do believe that when the Tuck company went out of business, Duck Tape came on the market. Betcha they stole the name recognition.
Looks likes a company called Cantech is producing Tuck Tape for the Canadian market and TESA owns the rights to the name. TESA makes some good tape.
Cool
Thanks Man.
U did not show to wire the switch to the blower . Just talked about electrical tape and plugged it in. Useless 😅
What about the ground wire for the plug? Not needed?
It's all preference. It's a safety feature and if you feel the need, by all means ground the motor and metal case.
I had a neighbor give me one and I built a stand for it. I can't use DEET everyday so I use the power of the Hawaiian Islands - a steady wind. Mosquitos can't fly in that kind of wind. I can't find a good wiring diagram for it, and would have to take the motor out to read the one glued to it. There is no blue wire, it's white, black, dark green, orange, red, and brown. I have white and dark green hooked up, and it blows good, and thanks to your info about back pressure, it no longer overheats. I have to start it by hand because it doesn't have a capacitor. BTW - if I use the black, it creates gale force winds.
Awesome.
I've used these as floor fans for years. Don't know why I didn't think of hanging in the rafters. Great idea! Love the multi direction tunes too!
It's nice to get it out of my way. Thanks.
Smashing fan and wiring discription :-D.
With a side port ring it could be very handy in a spray booth to suck the the nasty air out of the booth, i bet that would be really effective.
If you find yourself being dragged into the booth, use a lower setting ha ha :-D
Dogs allways make me laugh with the water biting :-D
Thanks Mate.
Good idea to share . That dog is a hoot. LOL
need to move the motor externally...for flammable fumes
Generally I only use it to supply clean air to a contaminated area. However this motor could be used in a flammable area as there is no switching, contacts or brushes internally that create sparks/ignition point.
