Anyone who has a larger capacity oiless type air compressor knows that these pigs are LOUD!!!
When I started occupying my newly finished basement shop, I wanted to have air, but knew I’d catch heck from my wife in the family room above, if I ran my aging Devilbus airless.
So I designed and built this noise dampening box.
3/4” plywood, lined with 1/2” sheetrock (to increase mass and give it some fire protection)
The compressor sits on a “floating deck” which is supported by polyethylene foam blocks. The key here is not to use so much foam that you never compresss the foam (like driving a 1-ton with an empty bed) , but not so little that it “smushes” (like driving a S10 with a pallet of bricks in the bed).
The sheet rock is covered with a fire retardant polyurethane egg crate foam.
The compressor does not contact the foam on the walls or ceiling.
Air connections are all made with rubber hose, so no sound transmits out hard piping.
I wired a switched recepticle inside the box, so the compressor is turned on via. the 20 amp switch on the wall above.
And I pulled the drain petcock and ran a hose to a ball valve on the outside for easy blow downs.
I keep the compressors regulater wide open, and mounted a salvaged industrial one on the exterior side for easy pressure adjustments.
There are air make up holes on the back side, below the floating deck.
1” birch plywood on the top makes for a sturdy work surface.
The door is gasketed and mounted with hinges and spring loaded twist latches.
All the air line are made up with quick disconnects, so I can open the door, pop the air lines, unplug the cord and wheel her out to the barn or a job site if needed…... though I broke down and bought a 100’ hose for when I need air in the barn.
Now the kiddies and mamma can watch t.v. in the room directly above and I never get a complaint whent he compressor cycles.
Finished it up back in the fall…. and it took way to long to complete. But now I have good air capacity without rattling the house down… and didn’t have to buy a new compressor.
Got the idea from this book…. Setting Up Shop
