Compressor box

- I used the Spectrum Analyzer app on iOS with the Fast Fourier transform analysis. The samples were taken with the phone microphone aimed at the compressor from about four feet away. Note the significant decibel readings as well as the frequency drop off.
This isn't a completed project at this point but the greater parts of it are done. I still will be adding a floor with dampening lining, casters, handles on the lid and sides, and hinges to the lid.
Having built this unit there are a few improvements I would make in a new build. Use 1" MDF, more space on all sides, use a more dense sound absorption behind the egg crate to absorb more of the lower frequencies, possibly similar baffles on intake and exhaust sides. - Наука та технологія
The fan for exhaust is essential when enclosing a compressor or shop vac. I built a 6' x 6' x 6' "closet" off the back of my shop to house both machines. I also installed two computer fans powered by a small solar panel. One fan brings fresh air in and the other fan exhausts the air. I've seen many boxes like yours but without the fan you installed. Then they wonder why the motor overheats. I like the whole set-up, especially the drain valve. Something I didn't do, but will now that I see yours. Thanks for sharing!
You could try using rubber legs under the box and compressor to minimize the resonance.
Great choice on the shop floors. I did the same.
Nice design! I particularly appreciate the quick connects and thought given to draining the compressor.
A few thoughts:
- switch on the outside
- if you want more air circulation, try a quiet bathroom fan; they are designed to overcome more back-pressure than muffin fans.
- aftercooler (outside the box? Inside, with an additional fan?) to help separate moisture
- temperature gauge?
I enjoyed your video. It was very helpful. Thank you!
Keep an eye out - I just sold this one (compressor, box, and controls) to upgrade. Next model should be vastly improved.
Хорошая идея! У нас два компрессора от холодильников подсоединяют к ресиверу и можно в домашней мастерской работать.)
Great video! Straight to the point. Thx!
Great idea, but it appears that the air flow may be too restricted. Have you had any issues since you've built the box? Any adjustments?
How is the intake dual baffles look like? I’m a bit confused on that part. Great build!
Nice job
I was thinking of doing this same thing but doesn’t make sense to spend twice as much on the box than on the compressor. I decided to try one of the newer husky oil less low dB compressors. Bought a 20 gal stand up for $220 and measured sound level with a friends dB device. Averaged 74 dB and is by far quieter than my older 10 gal. No box needed and I love it so far.
I went through 3 of those Husky uprights. Each one failed in the exact same way - the pressure line from compressor to tank blew out. I ended up moving to the Ridgid dual tank.
Really though, you should build a compressor box significantly larger than I did. There should be much more room. Also it shouldn't cost you more than $40 to build one of these boxes. $20 for a 4x8, $10 for some insulation, $10 for a fan. Well worth it in any case.
FYI for future videos, it'd be good to put the before and after spectrum graphs SIDE-BY-SIDE for easy comparison.
Really a decibel meter would be great. In person I can absolutely tell you it's much quieter. No more yelling.
Armand Hindrichs I really like your idea great job man 👏👏
Beautiful 👍👍👍
Nice work Armand.
I am building a sound deadener for my upright compressor. I will be using a 6x6 exhaust fan. Should I put the exit hole for the fan directly over the engine, or directly opposite the exhaust ? Thank you for help.
Exhaust? Are you doing this for a gas powered compressor then?
Can you tell me what brand regulators l you use? And also what quick connects and fan did you use?
I have the same compressor and I like the design of you're isolation box and I think id like to make one similar with a few tweaks of my own.
Thanks
+metalmalitia23 I wouldn't recommend my regulators at all. They've given out on me about 3 times. Go spend some money on them though! If I had to build this again from nothing I would use a different compressor and more insulation material. It is very quiet but could be better for certain.
Would probably be even quieter with rockwool rather than the foam. Fire proof too!
You probably dont give a shit but does anybody know of a way to get back into an Instagram account..?
I was dumb lost the login password. I would love any help you can offer me.
@Cameron Makai Instablaster ;)
@Armani Julius Thanks so much for your reply. I got to the site on google and im waiting for the hacking stuff atm.
Seems to take a while so I will reply here later with my results.
@Armani Julius It did the trick and I now got access to my account again. I'm so happy:D
Thanks so much, you saved my account !
@Cameron Makai Glad I could help :)
Hi , good box but l need to bring mime to a lower level , has anybody had the idea to build a sealed box, what would happen if you take pump off the motor and place it in a oiled filled box, drive shaft going throgh a seal in the box to the motor, inlet pipe going through a seal to a car air box, outlet pipe doing the same going to a tank , crank filler having a pipe to the outside of the box as well. I know it sound mad
Great design and construction Armand! However the foam used is not the optimal material.
It is a common mistake I also made: pyramidal shape foams are good to reduce reverberation INSIDE the room (box in this case) therefore are used in radio and music studios. For the quality of the sound let’s say.
Unfortunately this very light foams simply have not enough mass to effectively prevent the sound from getting to the outside.
For this purpose there are specially heavy „sandwich“ plates with the spring effect. They are able to provide an almost total sonic isolation.
So that would be my suggestion for improvement.
Old design - definitely first prototype level design. The type of material I used to sound proof my music room in my house was exquisitely expensive by comparison but I didn't want to budget too much to this. It served the purpose, but that compressor since has broken twice... so I moved to a different unit.
Armand Hindrichs I’m curios did the compressor break twice since because it may have overheated in the box or other reasons? Looking to do this to my 30 gal upright.
would be nice to add a timer to let the fan running after compressor cut off because compressor body will be still very hot.
I had debated on this concept as well but usually what I ended up doing was just opening the lid after use.
what the application do you use for fft analysis?
Great job Armand. How are you running the fans for airflow? I want to connect mine to the compressor somehow so that it turns on when the compressor does but havent been able to figure it out. I have the same compressor you do. Thanks
The fan is wired to run non-stop unless I unplug the box. It's such a small fan I figured it was better to keep it cooling the the whole time than be intermittent. There are some temp-controlled models by AC Infinity (same brand as my fan) on Amazon as well.
I see, thanks.
Ok so that’s the noise I hear when the AC unit in my house turns on. I first thought it was the fan motor
Just buy a silent compressor?
Right on man👍
Great solution, looking on your measurements you could maybe put some antivibration feet's under the compressor, to reduce the base:-)
That was the plan that I never got around to, but the next air compressor I do this to will be a much more thorough design.
What type of fan is that? 110CFM, 120MM?
Looks to be a solid design man... I'm going to build one soon and do a video on it... But I worry about the balance between reducing the sound while restricting the incoming air for the pump... If it has to work harder to suck more air in it could shorten the life of the pump... Over heating would also be an issue... Making a small exterior building would be good but not the most practical... I guess it's all about finding the balance... Sorry for the rambling comment... Again your design looks really good... It's like I always say... Let's all learn from each other.
Joe
I would advise putting a fan on bottom and another on top instead of on sides like I did. Also I'd keep a larger control volume to help the intervals of on and off with the compressor generating heat. The design went pretty well but the compressor bit the dust after 3 years of moderate to heavy use. I need to build a box for the new compressor.
Good idea... I've been planning with some designs ideas tonight... I figure I'm going to give a little on sound in order to have enough air flow and heat reduction... I'm going to cut ports and use furnace air filters on at least two sides... I'm also going to install a small 110 volt 10" fan... Only one fan though because I have a 30 gal compressor and need the over all size of the boxes to be as compact as it can... My mini fridge is going on top... One fan placed right should draw in air and push it out the other side passing over the hot pump... I'm also going to run a stand alone 20 amp circuit for the compressor... It only requires 15 amps but the extra power will be for the fan... All will be controlled with one switch... I'm sure I'll change a few design ideas between now and final production but that's about where I'm at... Your videos and videos like it really help... If you want to check out my channel I have a could basic videos with my compressor break in and drain install... But in a couple weeks I should have the box built... Thanks again for the ideas...
I got my 120V AC fan from AC Infinity (cheapest). They also have thermostat controlled ones but frankly they should be on all the time if you're using the compressor. That heat builds up quickly, especially in Houstons heat. You can get around the sound by doing sound baffles with your fan designs. A strong fan will be able to pull a good amount of air through a few baffles without too detrimental of a loss. Baffles are the key!
Thanks... I'll search for that fan now...
AC Infinity AXIAL 1238, Muffin Cooling Fan, 115V AC 120mm by 120mm by 38mm High Speed???
An old chest freezer would keep the sound down and keep it cool. 😁. But seriously, a chest freezer would be a good starting point.
If you want to make it quieter .. play with the length of the intake pipe and add a simple muffler. that's where all the noise is coming from.
Fucking Genius I’m going to Home Depot first thing in the morning lol
Maybe you can use a different window than the rectangular one. You would see a different picture at 60Hz.
Nice
why do you need those red gauges can you use the compressor with out them they don't come with them so how do they help
Those gauges are on regulators. Some tools can only handle a certain amount of pressure so those devices are used to set a maximum pressure in that line.
mggcomputers also one is water separator and and one is for oil, if using air tools they like lube and less water, if spraying you just use water separator with out the lube one ,
mit dem kleinen Ventilator wird der Kompressor wohl bei etwas Dauerhafterer Benutzung
überhitzen...
Lieber von vornherein in Richtung Gentilin oder Implotex investieren !!!!
Shheeeiit...thing's gonna sound better at the bottom of the local river IMO
wow
Should of got a Better/bigger 2 stage compressor with a dual isolated box with the vent going outside via a hose with a down spout
This entire setup cost me something like $200 and you want to talk about a 2 stage compressor?
That's great I was being more realistic for general automotive shop use.
I foresee cooling problems; good luck.
You make these for sell let me know
What about all the heat buildup?
...did you not see the fan?
It takes a long while for the heat to build up on a set up like this at work, the only time it over heated to my knowledge was when is ran for about a hour and a half non stop. If being used moderately or even the more tame end of heavy plus given time to cool off, I doubt it would be a issue.
"As you can see, it's pretty loud" lol
Ayy lmao
Much better
for all of that work and cost of materials I think I'd rather just buy one that's engineered to be quiet without an enclosure.
secretspy711 yeah, good luck with that
i notice the bottom is not covered (?) this might leave the bass sounds and vibration .
This was an almost-complete project at time of the video. Really it should have a closed platform bottom and some sort of rubber type feet to decouple it from the ground.
not bad at all
👏👍😜
That is a cool box, no doubt, but for the money you spent you could have bought a California air
How much did I spend?
how do you drain the tank of water at the bottom now?
+bruce achiles That's what the 1/4" ball valve is for.
for the time and money put into this box you could have bought an oil injected compressor that would be 50% quieter and you would have a better compressor.
Some of us just do what we can with what we've got until we can upgrade. When time is free and wood chunks are sitting around you can become creative also.
How much total was it to create this?
4x8 sheet of 3/4MDF - $30, box of screws - $4, AC 120mm fan - $18, sheet of foam - $30, air plumbing for drain valve and air to front controls (excluding controls) ~$30, and I wouldn't recommend the filter/regulator/lubricators I had. Pick some up from PneumaticPlus and they'll be rebuildable and higher quality.
i think i would have made it a little bigger for more air circulation and 2 fans plus switch on the outside so you wouldn't have to hear it at a high DB at all. just my thoughts . you did a great job though I like it.
If I were to build another it definitely would be significantly larger with 2 fans for sure. These were some cuts of wood I had already around the shop so I made them work. Definitely too cramped though. I'd also put fans on top and have inlets on bottom so we get the hot-air-rising effect working with us.
Mazda Miata guy ?
List of equipment please
Still very loud.
Get a newer compressor, they’re a lot quieter.
you should add a second fan for redundancy, and you can't measure that with an iPhone lol, worse piece of hardware known to man.
The iPhone is fine for a differential analysis.
Providing it actually works linearly, which I very much doubt.
Any app designed for sound analysis beats just listening to a video. The video is likely to have AGC (Automatic Gain Control) applied to even out the sound level, which will hide any improvement.
hi every one ,l was going to make my own compressor box,but they don't seem to get down to the noise level l need , ok this mite sound mad , what would happen if just the compressor pump was in a box with oil , drive would be on the out side shaft going through a seal , inlet wood be piped to a car air box on the out side , outlet wood be passed through the box to the tank , same with the crank filler and oil level view .l know l can make it work , just don't know if it would work for noise level .
@@lesariordan249 . Rocket 🚀 science 🧬
lots of work for a small reduction in noise,
12 dB cuts the loudness by more than half to a human ear. Quieter than your Junkrat video at any rate...
next time let me do your box big boy ;)
i can suck a golf ball through a garden hose :-*
Dommage se n'est jamais en français. Grrrrrrr!!!!!!
Sorry to inform you but the fan on that position is doing nothing in terms of evacuate the engine heat and provide a nice ventilation. Better if you place it just on top of the engine, and at the bottom of the box open a ventilation in order to create a nice air flow.. Anyways if you are not using it too much it could work. The noise isolation is very good ;)
Sorry to inform you that it works extremely well. The heat sink for the motor is at the top of the compressor so I placed the inlet and outlet to maximize airflow across it.
Armand Hindrichs :) airflow with all that foam around the outer fan... Maybe in your imagination
It's hard to argue with tangible results as opposed to your online speculation. Go troll elsewhere.
@eduki, How could you possibly know that without measuring the temperature with and without the fan?
Just buy a shhhhh air
All you really need is a muffler for the intake. Next time cover your hand over where the air is being sucked into the compressor for a quick second or two and you will see how quiet it gets. That's where most of the noise comes from. The part is available for most units. This is a huge waste.
@sjuul cnc yours is better
My ps4 Will fit Good inside👌🏽
