how to quiet down air compressor

[aka Larry]

I used the Soleberg as recommended by other GJ members on mine and it makes about a 5dB difference. Easy peasy to install, cheap, and effective. Get one, and you won't be dissapointed.

Plumb it outside , that is assuming it's a real compressor and not a oiless thing .

I am trying to do the same thing to my older Campbell Hausfeld 60 gal. compressor, but when I took the factory filter plastics off, I have no threads on my pump's intake. I just have a thread-less 1/2 inch hole with two bolts on each side, do they make anything for this type of connection?

On my compressor, 5hp, 80 gal, 18.4 cfm @ 175psi I installed a mufflet from North Central Air, Downs Ks. When I received it I thought it looked like a fiberglass muffler you would put on your car. My compressor head was threaded 1"npt so I used a street el and a short ****** and threaded the muffler in, put the existing air filter on top and it made it a lot quiter. I made an adapter and put an automotive filter with the foam wrap on it and it helped even more, I can actually listen on the phone within 3' of it now. It was only $26 so I didnt bother fabbing one up for the other compressor, just ordered one from them.

Nice!

I've always heard that the intake was the source of most of the noise. Sounds like you guys agree.

I have an IR and a Champion. The Champion is hands down quieter. I keep it in a room off the main garage but the door is left open as I keep larger tools I don't use a lot. No problem being in the room with it running.

I think the noisiest part of my Champion is the check valve. It's a clacking noise but it's not coming from the pump or motor, it's coming from the tank.

It's already got a Solberg filter on it - factory part.

can anyone else comment on the extending-the-intake approach with black pipe up to the attic? That seems like a cheap and easy fix.

Let's start this off by saying that I haven't done this but have read on this forum about people that have. I have an attached garage and I'm pretty sure that if i put the intake in the attic I would hear it more in the house.

...but if you really want to go this route you want to put something flexible between the compressor and the pipe. If you don't the pipe will get vibration from the pump and cause noise. You will also get vibration in the wall and if it's an attached garage you'll hear it in the house.

I have an older CH 60 gallon cast iron pump, it's equipped with a Soleberg filter/silencer. As a test, I removed the filter for a minute and listened for any change in the noise. Without the filter/silencer, there was a change in the pitch, it sounded higher and sharper. With the filter, it sounded a bit lower and dampened. Much to my surprise, the overall amount of noise coming from the compressor didn't change much at all, with or without the filter.

Here is a temporary set up , it did quiet it down a little...

Ive heard that car mufflers work wonders.. im going to try it when I get that far in my build.

I can give some great insight on this because of the system that I just got done building a couple of years ago and I could not be happier with the results. started with a 5 hp 80 gallon.and used it like this for 15 years listening to this thing. fabricated a 3/4 steel tube frame hinged it on one side and covered it with 1/4 recycled plexiglass for round one. round 2 covered it with tones of recycled foam on the inside using 3m spray 90 adhesive then drilled holes in the bottom popped in some soffit vents for more air intake also gave the floor about and 1" of clearance for more air, used 2 120v 6" recycled fans hooked up to a thermostat which is set to come on at 95 f also lined the inside of the dryer ducts for the fans with dynamat
That made a huge difference but not there yet I cut a hole in the wall behind the compressor and brought the air filter to another room. omg. what a difference!!! BBBBBUUTTT on the other side of the wall were the intake was moved to was loud!! wtf! I just so happened to have a old motorcycle muffler close by,held it over the intake pipe and was blown away! so the next day i went out and bought some glass pack mufflers and a spectra air filters .
and the sound is almost completely gone! have not used a db. meter but I am hyper sensitive to loud nosies and it is now completely workable..
step three or more was to throw some paint at it and call it a day.

here is another pict. of the intake for the compressor.


here is a link to the rest of the details that me and my son added to it after it was done.

I find the noise on mine #1, the intake, I put a riser on the intake and this got it out of ear range (don't think it really lowered the noise but moved it directly from ear range). After that the most noticeable noise on mine is the tank at higher pressures (2 stage). When it starts out at 0psi i'm like wow not bad. Around 100+ psi the ringing of the 'bell' is more pronounced. Just playing by blocking around just the tank with plywood i noticed a big difference in my perception of the ringing.

But i usually wear ear protection anyways regardless just for the air tools.

That is one cool paint job in your video!!

I put mine in a back corner room of my garage and insulated the walls with Roxul Safe'n'Sound. Cut the noise way down. In retrospect I could've gone an extra step with a staggered stud wall or something to isolate the the drywall from the studs a little. Works well enough for me though, since there's another wall between the main bay and that back room. Sound deadening foam (for music recording) would be great, but fairly expensive.

Even exposed insulation can absorb some of the noise...just need enough space for the flywheel to be able to bring air across the pump

The muffler on mine does a good job. I'd rather not pull in hot-humid air even though I have an automatic drain valve. It is in a room by itself so the noise isn't bad. It's a Champion which is many times quieter than my 80 gallon Ingersoll which even in a storage closet with the door closed will wake the dead.
If humidity isn't an issue, go for it. That luxury isn't mine.
