Discharge control
for oil injected screw compressors
Discharge control components ensure that the minimum oil flow required for cooling and lubricating the compressor is maintained during start-up and off-load and when the user lines are fully open. Optional combinations with filtrations and oil temperature regulation possible.
Ensure the oil flow by keeping a minimum pressure level in the compressor. The integrated check valve prevents back flow from air-net during stop and idling.
