Engineered and manufactured in the U.S.A. The whisper series compressors reduce stationary compressor DBA ratings by as much as 25%!  A noise suppression device was first conceived by Polar Air engineers after feedback from competitor compressor users revealed a large number of complaints regarding the extreme noise level of their compressors in a work environment.   Stationary air compressor noise levels typically require owners to incur the added expense of a building or structure to house the compressor in an attempt to reduce noise in the work environment.   The Whisper can be installed and operated in all Garage, Farm Shop, and Industrial applications which eliminate the need for traditionally expensive and often inadequate separate buildings or structures to house the air compressor.  The Whisper silent air systems are already installed on the back of the tank with brackets that are fabricated for easy removal and low profile.

The Whisper dissipates compressor intake noise by channeling the intake air through a series of baffle plates and pre-filter media within the silencer cabinet.  As a result, the piston intake noise is trapped and dissipated within the silencer structure. As a result, the piston intake noise is trapped and dissipated within the silencer structure. It also acts as a secondary filtration for cleaner air.

This unit can be used for heavy industrial applications such as body shops, machine shops, poly foam insulation rigs, sandblasting shops, car washes, wood working shops, dry cleaners &many other uses.
