Series 2770 WOB-L piston pumps offer long life, clean air flow, and field serviceability, making them excellent choices for a variety of medical, dental, HVAC, and other OEM applications. Constructed of light yet rugged die-cast aluminum, 2770 Series pumps incorporate stainless steel valves with a patented recessed inlet valve. The cylinder is hard-coated for wear resistance, and all wetted aluminum parts are treated for corrosion protection. Oil-less, non-lube piston and cylinders, combined with an air intake filter, prevent air-flow contamination. Thermally protected AC motors are of ultra-reliable permanent split capacitor design.
