Engineered and manufactured in the U.S.A., these compressors reduce stationary compressor DBA ratings by as much as 25%! Can be installed and operated in all Garage, Farm Shop, and Industrial applications which eliminates 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. Includes Industrial Plus piston air compressor and environmentally friendly refrigerated air dryer.<BR><BR><B>Features:</B><ul style=Margin-top:0px; padding-top: 5px; padding-bottom: 5px;></li><li>All steel connecting rods with replaceable rod bearing inserts. This allows our rods to be rebuilt. </li><li>Removable 100% cast iron cylinders. These solid cast iron cylinders are more stable under heavy workloads and do not warp from heat. </li><li>All cast iron cylinder heads. Cast iron heads are more durable and dependable for trouble free operation. </li><li>"Disc valve design" intake and exhaust valves. </li><li>Top quality compression and oil rings. Our rings ensure performance with low oil carry over (1-5 PPM). </li><li>Precision ground pistons machined to tight tolerances ensures low oil carry over. </li><li>All cast iron flywheel with built-in fan. </li><li>Built-in head unloaders. This feature reduces internal pump heat from compression because the intake valve is held open throughout the unloading cycle. This allows fresh air to come into the cylinder chamber. </li><li>Built-in inter-cooler and after-coolers.</li></ul>
