LE oil-lubricated for single-stage compression

The single-stage oil-lubricated reciprocating compressor allows filtered air to enter both cylinders through the inlet valve. The piston is driven forward through the connection rod attached to the balanced crankshaft. Maximum operating pressure is 10 bar (145psi) and capacities range from 3.4 up to 31.7 l/s at 50 Hz, 8.3 to 79.8 cfm at 60 Hz. Air compressed in the cylinders leaves through the outlet valve when the pressure reaches 10 bar (145psi).
