Silent Air Piston Compressor! 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 Eaton 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.

COMPRESSOR PUMP At the core of our Eaton compressors is our pump. These pumps are SUPER quiet in operation and built too last!  We start with a solid cast iron crankcase. Unlike some competitor’s aluminum body crankcases – our solid cast iron crankcase will ensure stable crankshaft alignment and will handle more work load under heavy load conditions. Our pump also features a precision balanced solid cast iron crankshaft with Timken-Style stainless steel roller bearings on the front and rear of the crankshaft to ensure smooth & efficient operation with less drag and less energy use. Our pumps also feature several other key components that ensure durability and performance!

  • All steel connecting rods with replaceable rod bearing inserts. This allows our rods to be rebuilt!  99% of our competitors now use “throw-away” aluminum connecting rods in their pumps that have no re-build capability.
