I've seen two sets of ideas for enclosing an air compressor in a plywood
housing with soundboard to quieten the beast. One plan shows a box that
completely engulfs the compressor, all the way down to a rubber seal on the
floor with a sound baffled air intake. The other plan is much simpler and
covers the compressor from mid-tank up. The air intake is from the open
sides around the tank.
Has anyone done this type of sound control on their compressor? I wonder how
much it affects the compressor cooling. I live in Houston where we worry
about things like that.
All these woodworking books about heating the shop and woodburning stoves
are absolutely foreign to us in our climate.
I've done it. I don't know if it was wise or not due to the possible heat
build-up and potential damage to the compressor, but it was either that or
not use it. I put it in a plywood box using staggered 2x4's (making a 6"
thick wall), insulation between the 2x4's, soundboard on the inside,
sheetrock on the outside. Worked great to reduce the sound. VERY quite. I
did run a 3" PVC pipe to the outside thinking that might cut down some of
the heat buildup and to provide air for the compressor.
To save space in my small shop I'm going to move the compressor outside and
pipe the compressed air in. In fact today I tore the box down. I had
installed it permanently in a corner. Next time I'm going to build a box to
fit over the top and latch it to the base.
I was very pleased with how quiet I was able to make the compressor; try it,
you'll like it.

You will kill your compressor this way. The number one enemy of air
compressors is heat. You burn cylinders & rings, degrade your oil and
toast your valves. Unless you install an industrial size exhaust fan
to remove the heat, your compressor's life is going to be short.
I'd suggest a muffler. It goes on your intake where the air filter is
and significantly decreases noise. I have one on my Ingersoll-Rand 242
and, while still a bit noisy, beats the hell out of killing a $3000
I fixed these things for a living and saw people put plywood
enclosures around them and then wonder why they died.
