Quincy Oil-less Two Stage Piston Compressors

Quincy two stage oil-less compressors provide clean air at pressures up to 150 psig. They are popular choices for laboratory applications. All models comply with EPA health standards, as they employ graphite gaskets and Teflon impregnated valve plates.

These air cooled models operate at slow speeds, minimizing heat, while extending service life. They feature cast iron crankcases, ductile iron crankshafts, totally sealed bearings, and deep cylinder fins for efficient cooling. High air temperature switches are included for protection of the compressor.

All models are offered as either a bare compressor, or a complete module, including inlet filter, motor, drive belt, belt guard, and aftercooler. All two stage modules are also equipped with solenoid valve unloading.
