What is the Howden XRV 127 Manual?

1. Intake: As the rotor turns, the vanes slide out due to centrifugal force, creating expanding cells that draw in gas.
2. Compression: The cells reduce in volume as they approach the discharge port, compressing the gas.
3. Oil Injection: Oil is injected into the chamber to seal the gaps between vanes and housing, lubricate the vanes, and remove heat of compression.
4. Discharge: The compressed gas/oil mixture is pushed out through the discharge port into an oil separator.
