DIY Project – Air compressor noise isolation box

I decided to take up Airbrushing, so got myself an Air Compressor that would also be used for powering tools. Only trouble was, like most compressors, the thing was a noisy beast.

Decided to build a sound isolation box for the Compressor, so got a sheet of structural 15mm Plywood and built this box over a few weekends.

The box is kept cool by twin high-powered, low noise computer fans that I rigged up (poorly) with a 12V power adaptor, and the intake and exhausts both have a ventilation box with channels designed to let air flow easily but sound not so.

We had lots of carpet leftover from a recent installation so this was put to good effect. I added a small bit of fiberglass to the exterior air vent as it looked like it could use a bit of strengthening in case bumped.
