This Old Barn/Shop Air compressor

- Introducing the compressor that will be supplying air for the new shop. I picked up an old Devilbiss 445 10hp compressor that I can use as the foundation for my shop air system. It is a 1968 model so it is almost 50 years old I hope it is good for another 50 years. The plan is to place it in the old loft so it is up out of the way and maybe that will isolate some of the noise without creating all the problems that happen with an outside air compressor in an environment that is both humid and prone to freezing. I feel like I should probably rebuild and reseal it before getting the forklift and putting it in a much harder location to work on it. This unit is considered obsolete too so if I wait I fear parts might be harder to find. Opinions welcome!

FINE old rig. I sure like the sound of the old big bore jobs. That'd hold down the new long legged truck and make it ride good on the next haul. Baily didn't inspect it good enough and that's why it wouldn't light the 2nd time. You got the wag off now and Tom to boot!
Looks like a nice find. good video.
Love the patina of it. Love DeVilbiss as well. I think it would be an excellent conversation piece. But that dang thing would live outside
I would definitely give Devilbiss style points the check valve and regulator and the pipes all have art deco type castings that really make it cool looking.
..Yeah, I remember when a lot of old machinery made before WW2 was art-deco......
I love the vintage race car air cleaner on top, good thing, that beast sounds like a big block Chevy when she is running! I saw the arc flash shoot out from the smaller electrical box on top when you flipped the beaker. This is a top notch brand made for paint and body shops so it will far succeed your air needs! Thanks for showing her off!
...Arc flash....on something that looks like this....might just be loose wire/s or dirty contactor...
Yeah turns out they had the motor leads in copper clamps in that box but with NO TAPE!! WTF no wonder they shorted out with a little movement.
I am glad you did not have your hand on the air compressor when you flipped the switch! The shit some people do man, makes me wonder... Looking forward to the rebuild!
Another great video Bryan! Nice find, and glad you found it.
I had the use of a similar size compressor in my old shop, fantastic for running my blast cabinet. It was a Saylor-Beall, 4 cyl. Shortly after I left that location, the total dummy in charge replaced the leaky pressure relief valve with a plug and blew the sucker up. One of the cast iron intercoolers exploded and would have killed anyone nearby. Luckily, it was located outside in a breezeway. It looked like a bomb went off, totally severing a 2x4 wall and destroying the compressor.
So I'm just say'n, noise isn't the only reason to house a compressor outside.
I'm completely amazed at the progress you're making on the barn/shop, plus your other projects.
Keep those videos com'n!!
Both the intercoolers have pop offs to prevent that from happening.
Newer battery operated drills have come a long way. Just thinking of making a small chain pulley on 1, to make crane electrical. Just dumb thought, but loved to see attempt. Thx for vid and great find.
Nice compressor, it's a beast! I learned a long time ago to always insulate the feet and let the compressor draw in outside air through a box to kill the pulses, it brings the noise levels down, although that unit doesn't seem too loud. Just a thought.
That's a Monster. You will want it outside. Nice Buy.
That was the best part of the entire trip this week, Brian. Thanks for the hospitality! I'll gladly come work again - already planning another trip out there.
Best wishes,
Tom Z
PS - I've got more video of this too...
Hi Brian,
Another good haul, this will supply all the air you'll ever need, even full load sandblast...
Try installing something to get the air from outside if possible it will supply you with drier air in the Winter at least, also send out some of the intake noise outside...
Better get that floor done before packing up and having to play moving as you pour the concrete...
Cheers, Pierre
Look at the size of that damn hook! Awesome Brian!! 🎉
Yeah it is probably the size of a 30ton hook nowadays!
Nice score Brian. Best safety tip I've heard for our dumbed down world. Big pulley and four belts if u want to stick your hands in there. It's not about the beard or bulky clothes. If man is naked and shaved he still has those floppy arm things to control.
sweet score on the compressor... i have a few devilbiss paint guns, didn't realize they made compressors. Nice seeing Tom on the video, and for sure make him work for his food!
Well they don't anymore but devilbiss compressors became devair, and now dv systems they still build a compressor almost identical to this in Canada at one of the old Devilbiss plants.
Good find on that compressor! Nice to have the right thing to unload it and some help is always a plus!
Take Care,
Reid
Great machine Brian, It will probably outlive all of us!
Cool to see you back in the barn/shop!
Brian, Thumps Up!! Not bad for a 50 year old, Shop Air Compressor! (With proper maintenance your old "Devilbiss 445" 10hp compressor will continue running for along time!!) Really Good stuff! Cheers! :-)
Nice find!!
cleaned up pipes and electrical and it will be an awesome addition to the shop.
That's an awesome old compressor Brian. Good find!
You got Bailey all excited with the arcing and sparking!!!! LOL!!!
When there are problems at least he comes to help! lol
Nice Find Brian now you added more work plumbing air lines!
The work never ends!
No it never does!
Nice compressor Brian! You have some great equipment! Be safe and God bless you!!!!!!
The arc might've been a stray strand of wire, it has happened to me before a couple of times, hadn't figured it out until actually caught my mistake before it happened. The strand burns apart and you open the plug and it's gone. The perfect "murder". :))
That's a nice compressor and by the looks of the other videos, a nice rebuild too.
Nice compressor I like those built in coolers, she ought to make plenty of air.
I have smaller version 432 pump - looks identical but is a bit smaller when measured with max HP motor at 10, currently set at 5hp. Works great no issues. I think it will outlast me.
The old ones are all pretty well built and tough.
That one runs nice and slow to, so that helps wear and sound levels.
I would have held out for a Quincy with an oil pump, myself, but then you did
ask for opinions...
..Yeah, I was looking for a pressurized oil system on there.....A friend of mine recently bought a Quincy....a little smaller, but it had pressurized oil/filter ....
That baby may need an outside room of it's own.
I have a nearly identical compressor at work, same brand but a little newer. Very similar looking pump though. Its a nice machine, that one should serve you well.
...Yeah, plenty of inter-cooling an there too!
I know if u have a 432 model 4 cyl unit. Parts are hard to find..they haven't made the model # in 30 plus yrs.. i always say change the oil on a regular basis..if u know what the parts that whare out on yours get an extra,s if u can find them if you really love your pump..or a parts pump if u can find one ..they were great pumps for the 5 h.p. compressors. Quite running..great video..i own a 5 h.p. saylor Beall air compressor industrial type ..made in America..its in my home garage,i have and old restored rotary inground lift..i resuqed from an abandoned gas station ..1967 single post lift..it sat idal for 35 yrs we got it out of the ground and prayed it was not rotten out , it was in great shape..even the oil tank was good ..now above ground .new piping etc back in service in my garage
A company in Canada still produces these 445 pumps. It is called devair
Not bad for 40 something years old.
I think a small block house with insulation is smart.
And maybe a guard over those pullies and wheels.
Had to come back and hear the before. Huge difference. Belts are more tame in this video. Not sure if it is a minor alignment issue, or the difference in harmonics now that it pumping more efficiently. Looks like alignment to me though.
Hi Brian awesome piece of kit there. I think Tom is trying to slip that granite plate under his belt and make off with it at the end of the video. -Tee Hee. Thanks for sharing. Joe.
If he can carry it off he can have it!
Nice score Brian just keep check of the condensation and you should be fine.
.Yeah, that's the secret to long compressor/tank life....
Cool Find Brian, shame your truck disappeared suddenly like that after all the work you put into it, LOL
Lucky for me it just teleported to the outside of the barn this time!
Glad you found a good deal; now fabricate a guard for the belts and pulleys. I figure you can handle that just fine. Remember, we're watching! Greg
That looks like a nice compressor. Should provide plenty of air for you. Was that the pressure switch leaking, or the plumbing, or??? Keep going and you'll have that shop filled up before you pour your floor....lol. :) I'd be thinking about giving that a complete rebuild before the shop is finishing....should be an awesome compressor for you.
Just slow bleed down from not having the unloader open far enough. Those big pistons pipeing and intercoolers hold a lot of air.
That is a real air compressor there. No harbor fright stuff in your shop.
...Harbor Fright....Yes, they opened a store close to me....I walked around and didn't see a single thing I'd buy....the red shop rags were tempting, until I realized they were about 1/4 as thick as a worn out T-shirt.....
that kind of beast you want outside in its own house
Froze up compressors in the wintertime are such a pain though!
The mines I've worked at Brian always had compressors that large or bigger in the truck shops and they always kept them in there own cinder block room. Maybe think about a bit of additional heat/AC lines to a concrete pad outside? Easy enough to add an insulated enclosure around a compressor that small to keep it from freezing up. With the size of equipment you seem to luck into your gonna need all the shop floor space you can find before long. But heat with a small enclosure and large compressor is still something to keep in mind as I'm sure you already know.
Right, but if you need more air just get a diesel air track rig. A Cat or a 6-71 moaning outside would be nice.
Did you inspect the inside of the tank? Being that old might be some corrosion, and I don't have to tell you how dangerous that could be. Nice unit, hope it's sound. Thanks for the video.
Looks like another great aquisition. Here I am, looks like the non click bait works lol. You forgot the teaser for next one tho. Boy oh boy better get some concrete down or your gonna get it too full to pour! Haha
No kidding!
Keep going like that, you are going to have a tighter shuffle about of equipment while pouring your floor than I have in a 30 x 20 with 35 years of accumulation to manage :-)
i know you did it.. but check the tank welds where the top and the feet are mounted for cracks..
please pull one of the plugs in the tank and stick a fiberoptic camera in and have a good look around for corrosion.
if you build an upside down ice chest you can slip that over the compressor in the cold cold wintertime. use styrofoam sheathing. you can keep it warm with a a light bulb or even a magnetic block heater.
i was given an old 80 gallon vertical.. took 5 of us to tip it without the pump into my van.. somethings wrong.. too heavy.. must have had 60 gallons of water in it.. night crew opened the drain but nothing came out. so they thought there was no water to drain.. it was clogged.
when you /if you .. put in hard lines and drops. the fittings at the bottom of the drops should be Tees.. with the run continuing with a globe valve that goes into a bell reducer to a larger size of pipe with stainless steel choir boy stuffed in and a pipe cap with holes drilled.. air drain mufflers.
just a few thoughts. i know you know all this.. but others will pick it up also.
If you started selling tickets for operating that crane, You'd have a queue all the way down your driveway.
Hey Brian I have the exact same air compressor. It's a good one if you want any info on it I have some pdf's around here on it. it's nice and quiet for it's size too. I also have the original peerless motor for it as well. I would check your compressor speed too mine ran on 3ph @ 1450 rpm it was built in 1955. they have a few different speed ratings I think it's 300 rpm minimum but I forgot.
It is running between 575 and 600 rpm at the pump at rated pressure.
It is running between 575 and 600 rpm at the pump at rated pressure.
Looks good, you'd think it was full of helium the way that bridge crane handled it! Take Care
I run Helium in my truck tires too so it is lighter that is how I get the good mileage. :-)
You'd refill them daily too. :o)
Looks good a rust treatment and paint it will b a good up in the loft tho
Gettin there.
I just bought a Saylor Beall air compressor and it had the same problem with air pissing out of the unloader valve. I traced the problem to the tank check valve. The spring was gone in the check valve. A new $20 check valve from ebay, problem solved.
Hey Brian greetings from Canada! I am curious how many hectares is Bailey's property there in Kentucky? You are lucky he let's you put your tools there in his dog house!
...De Vilbiss....used to be top quality stuff, I hope it still is....AND ...I hope you don't have to rebuild it....likely cost as much, or more than re-hauling a car/truck engine...! I once worked in a Compressor sales/repair shop......hard to believe the $$ of parts...! Probably not an issue for you, you could just about make any parts...!
Just wait til I get my 1920s vintage quincy up and running. Then you can eat your hear out Brian! Haha. Not really though because yours is a lot nicer.
No reason you can't fix yours up to be nicer! :-)
That's a hefty compressor there which must have some serious volume output as well as pressure. However what will you have to do to get the water out of the tank if you put it up in the loft area as I seem to remember you saying you suffer high humidity as well as perishing cold in your area?
Install an auto tank drain........ that is the plan anyways.
...Yeah, cheap insurance....my last job was Maint. mech/elec. at a mfg. company....they never installed any drain valves....had a 200 gallon receiver that was 1/2 full of water....only reason it wasn't more...the air line came out at the center of horizontal tank.....$50 electronic timer drain valve sure fixed that one...!
mine is lofted and hard plumbed with two sets of lines. one is to a ball valve next to my light switches which goes outside our have a threaded end out there so if I need to use air outdoors I thread in a fitting there - since the tank is always empty I get very little moisture.
Hey Brian,
Gotta share your thoughts about the corrosion factor and health of the old tank. Buying an old tank doesnt raise the hairs on the back of your neck? Its what I am the most scared about in my own shop. I run my old sears compressor outside and run a long hose to the garage. I would rather have it blow up by the neighbors house than inside mine.....
Thanks, and cant wait for the concrete!
An old tank doesn't scare me at all. As long as the pressure relief valves are working properly it is extremely safe. A rusted out tank would likely leak long before it ever had a large enough section that was all damaged to the extent that it could catastrophically fail. If you drill a hole into a pressurized air tank it does not explode like popping a balloon. The only air compressors I have ever seen explode the tank were all over pressurized. You have to have enough stored energy to yield and rupture a large area in a very short time to get an explosion and the odds of corrosion causing an area like that even enough to create a catastrophic failure are astronomical.
Yeah....I'd just add on (if you don't already have one on there) is a timer condensate drain valve....
Currently a mechanical drain daily but a timer activated drain is certainly what I want.
a drilled hole does not explode because the meterial is uniform across its thickness. But rusted tanks that develop a leak explode because around the leak, there is thinner section. That's why there's videos of people's tanks exploding, and have read about it over the years on machinist forums. You could pressure test your to 500psi with water to make sure. Then it will just crack if its near its end. That's the safe way to do it, don't risk your safety this pressure test it with water and if it pops consider yourself lucky. The videos of tanks expoding on youtube are brutal.
so about 18 amps running? use compressor oil nothing else and i would run it for an hour or more use a infrared thermometer to find the hot spots. should come up with some kind of after cooler if it's putting out hot air. now they make self unloading water filters maintanence free. it's a must have in a parlor dairy. at work there's two 150 gallon compressors that run the parlor & crowd gate, have to maintain 150psi or the parlor gates won't open. only problem beside the occasional burnt run capacitor and the old circuit breakers tripping out sometimes is the line from compressor head to after cooler gets burnt up & leaks because it's just 3000psi hydraulic hose. you'll make it work for bailey ;)
Motor says it is 42amp, it doesn't pull that much though as it is currently on a 40 amp breaker and isn't tripping it.
...42 amps? Is that 3-phase at 240 Volts....?
How many CFM does that beast put out?
35cfm @175psi
Is the unloader valve not working?
I didn't have it adjusted properly so it was barely opening thus the extended blow down at the end.
....And there's quite a bit of stuff to blow-down with all the inter-coolers....Good Score though!
My old devilbiss is probably about 50 years old I dont know but still runs great. It has an oil pressure gauge. It has a leak in the dump valve so I am also thinking of a rebuild or partial rebuild so I will be checking into parts availability and if I find good source of parts I will let you know.
Is the unloader leaking all the time or just when it is pumping? if it leaks all the time it is the tank check valve not sealing and leaking back thru.
...Either one is low $ to fix....tank check valves are often easily dis-assembled and fixed....sometimes just sanding a clean surface on the sealing areas...lots of them are UHMW or other plastic....
I know what you mean, a good deal is hard to pass up, but I would think you should finish your floor, moving things around again and again , takes time, that could be used making chips, just sayin . good work and good videos Bill
The drill trip got cancelled for a couple of weeks so going to try to hit it hard on getting some floor poured before I bring the drill back. Doing things in a better order is preffered but sometimes it just doesn't happen like that.
Do you have any way to check for corrosion on the inside of the tank at the bottom where condensation would collect? There is a video of tubal cain cutting apart an old air tank which had only a fraction of the wall thickness left at its bottom. If your thing will blow out at its bottom it will become airborne and who knows where it will go then....
It would be fairly trivial to give the tank a 300 PSI hydro test. If it can hold 300PSI it should be good for 200.
yes that may be a method. But by filling water in the tank and later when draining it not being able to get all water out you may accelerate corrosion. And since it is an old tank you might have to repeat the test every one or two years.
There is a fair amount of humidity in the air. Compressors inherently turn this into a lot of water in the bottom of the tank. Even a small shop compressor can turn out several gallons of water a day in the tank. So you need a tank drain that works moderately well. And of course you need to use it frequently. You would use the same drain hole after a hydro test, and while it won't get all the moisture, the compressor will start making a lot more as soon as you turn it back on.
I guess you are right. Then you still would have to repeat the test in 1 or 2 year intervals. I was thinking about methods to prevent corrosion instead of only testing the safety while corrosion progresses. I was thinking of a sacrificial anode like it is used on ship hulls and steel tanks in the ground. You put a zink anode (thick strip of zink sheet) in the wet spot inside the tank bottom and screw or rivet it to the tanks wall making electrical contact. May be it can also be clamped in place by the drain valve body. Or make the drain valve body itself out of zink. That way the zink will be eaten away while the steel will remain untouched. Then you need only to replace the zink part like every 3-5 years maybe. And no further hydro tests would be needed.
I looked inside it has rust, I am not surprised based on its age. I also am not worried. See my response to Jeff discussing rusty air tanks aka pressure vessels. Main thing is be sure your relief valves work!
How much pumps that Thing liters or gallons per Minute?
35cfm at 175psi
Almost sounds like a poppin johnny all revved up. Even yer compressor sounds like a pullin tractor..
aren't you afraid, buing a really old compressor, it is rusted inside and might explode?
No see my response to Jeff.
Any idea on the CFM?
I think 35CFM @ 175psi is what it is rated.
Wow, that's no slouch. I picked up an 80 gallon for a few hundred bucks, rewired it and it turned out to be 17 CFM which is far more than I'll ever need doing automotive type work.
"Will work for food."
Aren't you at all worried about the integrity of the pressure vessel?
Justin Bell just hydro test it to 300psi it should be fine
Not really, see my response to Jeff.
Time for an oil change.
...Yeah...I've worked in a few shops, and a Compressor sales/repair company.....seems like pretty much no one ever changes their compressor oil.......
Sadly time for a rebuild. I bought it figuring it needed rings based on it having some blowby in the crankcase. I am glad I tore into it as it was fixing to have a lot more issues. I should be able to rebuild it and have a known good unit and have less than $1k in the whole thing so not great but not awful either.
bcbloc02
Only $1,000? You wouldn't find the stamina in a modern day compressor without paying three times as much.
bcbloc02 the rebuild would make a great video series, especially if you explain the theory of operation, like the multiple stages (I assume this model has them) and the unloader valve thingy. Thanks for the videos.
That air intake filter isn't original equipment!
Looks just like the factory ones I have seen online, what makes you say that?
OK, so I'm wrong (again :( )
Since you said the compressor was over fifty years old, I thought "That looks exactly like the air filter wossnames you see on many large US-made motor-car engines!".
That thought led me to the obviously erroneous conclusion that someone had replaced what I thought (wrong again) would be a large and robust and simple construction, perhaps an oil-bath air filter, such as you would see on a Farmall (?) or early Ferguson, with something he took from his younger brother's derelict Chevrolet Impala.
I suppose you shouldn't rely on instinct, should you?
I thought it was a reasonable guess....
hey i got the first view and the first click on the like button , never had that before .
johno
Congrats I guess then!
