Features

• High-flow, automatically reversible oil pump provides positive-displacement oil lubrication.
• Crankcase venting system equalizes pressure during startup and assures oil return to sump.
• Oversize sump holds extra oil in crankcase to prevent levels dropping below safe lubrication range during flooded starts.
• Contoured pistons lower cylinder clearances to increase compressor capacity and efficiency.
• High-efficiency valves provide increased refrigerant flow and lower pressure drops.
• Electronic oil-pressure switch.
