Recommendation for quieting my compressor pump

[pault28]

Hello all,
I've been looking into some of the solvers compressor silencers and am not sure which one to get. To keep the whole system small, I think I will have to go with the round ones, not. The long cylinder shaped ones. Seems most of the small round ones may be too small for my pump though. Most of the 1/2" male pipe thread round silencers arerated for 10cfm. that may be enugh since BOTH heads combined on my pump put out 16.8cfm @90 and 14.3cfm@135psi. The cylinder heads have 1/2 female pipe thread inlets. Its quieter than my old oilless, but i still would like it quieter as my garage is not too big so there is no hiding from it when it runs. would the isolation pads underneath the feet help too? right now it is right on the concrete floor, not even bolted down.

Any suggestions?

I built a cabinet and put my whole unit in the cabinet. Put a couple vents near the fan at the back and one on the side to allow airflow. It made a huge difference. I can work in the garage with the doors closed and not go deaf from the drone of the compressor.

Not sure on this.

Whatever you decide, please post with pictures & results. Earmuffs get annoying!

Is that a 2 stage pump? Is so then 1stage compresses to a certain psi then the second stage further compresses. I'm not sure the logic of 10 cfm per cylinder holds.

I have a universal silencer that is about 18 " long and it dropped the dba about 3 points. Overall not bad but not what I would have liked.

If you have a farm supply store, the horse stall mats are pretty cheap and really stout. I put 2 24"x24" pieces under the whole compressor and am very happy with the stability.

My compressor is not a 2-stage. I was thinking a while back about enclosing it, but decided against it because my sub panel is in the same corner and I need access to it. I will rey first the horsetail and see if that helps. I do think two new silencers and a mat or pucks would do the trick.

The only reason I thoughtaybe 10cfm per cylinder would be ok is be ause it is a single stage compressor so in theory both heads are pumping the same amount.

I also have a 2-cylinder 1-stage that is very loud. Suggestions welcome.

Mine is still sitting on the shipping pallet after 5 years, its still pretty noisy. I don't think the rubber mat underneath is going to quiet it down as much as you would like.

99% of the compressor noise comes from the intake system. Pipe it outside with some large PVC and I'll bet it gets much quieter.

Hello all,
I've been looking into some of the solvers compressor silencers and am not sure which one to get.

I quieted one down a few years back for a friend of mine. It was a three phase unit about the size of a refrigerator. We went the rubber pad route first using pieces cut out of mud flaps.

It helped a little, but the major noise source of his compressor was from the air intake. I piped the air intake into a piece of stainless flex pipe we had laying around. I guess that it was about 2 or 2-1/2 inches id. The next step was to snag a used muffler off of something laying on it's side in his wrecking yard.

MAJOR noise reduction. We ended up making a remote air filter for it that used an automotive air filter, some pvc pipe, and a piece of stop sign for the base.

A ninety degree bend in the flex pipe between the muffler and the compressor made a difference too. It was amazing how you could straighten the pipe and then bend it while the compress or was running and hear the difference in noise level.

I was just thinking. A glass pack would probably work even better but you might have problems with the fiberglass eventually getting sucked into the compressor. You'd have to plumb the glass pack upstream of the air filter. Come to think of it, I haven't seen a glass pack in twenty years. I'm not even sure that they still make them.
