Paradox Reciprocating Compressor (5-15 HP)

Gardner Denver has always prided itself on bringing the most innovative technology to the marketplace. There is no better example of this than the state of the art, re-designed Quiet Enclosed Reciprocating compressor package. Using our legendary R-Series compressor pump, this compressor combines the reliability and high performance of our flagship compressor pump into an enclosure that provides optimum cooling and low sound levels.

The Paradox is ideal for applications that require the technology of a reciprocating compressor but also lower sound levels. This compressor has dBA levels as low, or even lower, than a typical Rotary Screw compressor and approach temperatures less than 20 degrees.
