Details on tips for silencing the loud noise emitted from an air compressor.
[edit] Procedure
- Frame in your air compressor with 2x4 construction in a permanent location.
- Cover interior walls with peg board or wire mesh.
- Cover all sides with foam over the peg board (example: 1-inch thick foam).
- Cover all exterior walls with peg board so you can hang your tools on outside.
- Place rubber mat on floor for the compressor to sit on to cut down on vibration.
- Make yours with a door in the front for access.
[edit] Alternatives
Build a lean-to addition on to your shop, and just pass the electrical and air cables through the wall. In summer, you can open two opposing windows and let the breeze cool the compressor. In colder weather, you can keep the windows closed, or open them slightly for ventilation.
alternative ideas...
- space the 2x4s for fiberglass insulation, and use that rather than foam.
- use anything (even tack old paint sticks, lattice...) on the inside to prevent insulation from falling into compressor area.
- use plywood on the exterior (maybe even interior) of the structure, and then if need be add pegboard to hang tools from. This will increase sound deadening even more.
- BE SURE TO HAVE ADEQUATE VENTILATION FOR COOLING MOTOR AND COMPRESSOR- unless you don't care how long it lasts. You could also 'oversize' the structure so there is adequate airspace within to keep the compressor cooled for intermittent use. For more steady use, I'd suggest opening the door, which you can face away from the work area to help keep things a bit quieter in the shop.
