Chicago Pneumatic
HN Series
The Chicago Pneumatic HN Series represents one of the most robust and reliable families of 100% oil-free reciprocating compressors available for industrial use today. Designed with a horizontal balanced-opposed (BOP) architecture, the HN Series ensures exceptionally low vibration levels, smooth operation, and long component life. These compressors deliver clean, oil-free air across a broad pressure range, making them ideal for industries where air purity and consistent output are critical — including pharmaceuticals, food & beverage, textiles, electronics manufacturing, instrumentation, and high-precision process industries.
Each HN model is built around a time-proven multi-stage reciprocating compression system, stainless steel valves, PTFE-based piston rings, and a rugged crankshaft assembly engineered for continuous duty. With motor capacities from 120 to 215 HP, the HN Series offers impressive free air delivery ranging from 517 to 1644 CFM and supports low, medium, and high-pressure variants (2.5–15 bar). The compressors are designed for minimal maintenance, thanks to easily accessible components, durable wear parts, integrated auto-drain systems, and advanced protection via Chicago Pneumatic’s ES controller lineup. Optional VSD (Variable Speed Drive) configurations further enhance efficiency by matching compressor output to real-time air demand.
