After coming back from holiday I finished the anti-noise enclosure for my compressor and made a muffler for the intake (shamelessly copied from a tip on VAF). The neighbours say that they can't hear the compressor running. I guess time will tell if they were just polite or really don't hear anything. Anyhow, it is a huge improvement for the workshop and makes using the compressor pleasant.
The enclosure standing on its side. Air is blown into the box and directed to the motor and compressor block. The box is made from 18mm MDF.
The interior of the enclosure is padded with felt blankets. I found the idea for the muffler on VAF and it works great. On the left you can see the 135 cfm fan I installed for cooling.
The front cover is removable.
Right now the filter/regulator is still fixed to my kitchen table.
