Quincy WIS Series Oil-Free Rotary Screw Air Compressor

Quincy WIS 20–75

WIS 20–75 HP Oil-Free Water-Injected Screw Air Compressors

When your process requires clean, oil-free compressed air without sacrificing energy efficiency, WIS 20–75 HP water-injected screw compressors provide a reliable solution. Available through Compresseurs Québec, the WIS range uses water instead of oil within the compression chamber to support ISO 8573-1 Class 0 air quality for sensitive and contamination-critical applications.

Water’s natural cooling capability helps maintain lower compression temperatures and achieve near-isothermal compression. By reducing heat-related energy losses, the compressor can deliver more compressed air per kilowatt of power while placing less thermal stress on internal components. The result is efficient performance, dependable operation, and longer equipment life.
