 Air Compressor NoiseProblem:
A shop air compressor located in a corner or against an adjacent wall with constant or intermittant motor and compressed air noise emanating from the compressor. The noise levels are compounded by the sound reflecting off these walls. When the air compressor cycles, the noise becomes a nuisance to personnel in the area.

An enclosure made of Model UNC-25 sound curtain panels surrounding the air compressor. These enclosures are typically two, three, or four-sided (and of sufficient height) with an open top. Optional roof and silenced ventilation options are available depending on the application.  The video below shows an installation of a similar sound curtain enclosure around a compressor.

The illustrations shown below are: (on the left) a four-sided enclosure with roof and silenced ventilation, (on the right) a two-sided enclosure using sound curtain panels.
