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. Oilless, nonlube piston and cylinders, combined with an air-intake filter, prevent airflow contamination. Thermally protected ac motors are of ultrareliable permanent-split capacitor design. Twin fans provide efficient cooling of the motor and cylinder. Piston seals are TFE. Series 2770 pumps provide up to 100 psi (6.9 bar) of pressure. Maximum flow is rated at 7.4 cfm (209.5 lpm).
