Air Compressor Box

[UROK]

IIRC there was a post or links from forum to photos of someone who built a very cool box to contain their pneumatic compressor thus reducing workshop noise.

It was really well done (an authorized builder?) with the pressure gauges etc all brought outside the box.

Anyone know what I'm talking about?

Searching with "compressor" and "box" didn't get me very far!

It's quite likely those posts have gone down the "data drain"...

Both work fine.

Excellent material! Bookmarked.

I am most grateful. Thank you.

Sure my neighbours are too!

Make sure you have good ventilation built into the box (especially with an oil-less compressor) as the extra heat will shorten the compressor's lifespan.

Understood.

Many thanks, Jon. Will certainly bear that in mind.

Compressor hunting about to begin...

I've built one and used the box as the base for my 8" table saw and router table. The only thing I would do different is add a fan. I installed an external temperature and pressure gauge. The key is to make the box absolutely air tight except for the air intake which must have a long convoluted sound insulated path. I also used 3/4 Baltic Birch, rigidity and bracing is important. I mounted the compressor on a piece of thin plywood supported in the middle by a spacer block making the plywood act like a spring shock absorber. This reduced the mechanical transmission of vibration thru the sealed box. It was very effective in eliminating almost completely the compressor noise. I did post pictures here at one time if I recall correctly.
The two links Sydney supplied has good info.

Hey WB. Thanks, man!



That's so helpful.

I thought it was you and checked your pics (great builds BTW - super clean) but couldn't find the photos.

I'll check your posts for the pics when I get home tonight. In the meantime, many many thanks again! Those are fantastic tips that I'd never have thought of on my own.

Thank you for sharing!

No problem UROK. I culled those pictures last year, but put them back for you:

Those are the ones!

Thanks, WB!

One quick question: why gaps in the convoluted foam lining inside and on lid?

One quick question: why gaps in the convoluted foam lining inside and on lid?

Lining the inside is the least important aspect simply because it will only attenuate high frequencies which have zero chance of escaping. I was basically using left over pieces of foam (hence the gaps) on the basis that it probably won't help but also wouldn't hurt. If I were to do it over, I wouldn't bother. Where foam is beneficial is in the air intake path.

Word. Makes sense.

Thanks.
