Description
Reduce oil carryover into the intake with the PERRIN Air Oil Separator. The separator removes oil droplets from crankcase ventilation flow before that airflow returns to the intake system.
The installation’s ventilation connections, mounting position and drain arrangement are specific to the engine. The design details below explain how this version manages separation and servicing.
Design details
- Engine coolant warms the separator body to help manage condensation during oil-vapor separation.
- Internal flow paths combine swirling motion with impact surfaces to separate oil droplets from crankcase ventilation air.
- Separated oil returns to the engine through the installed drain arrangement rather than collecting in a manually emptied reservoir.
- The housing can be opened for cleaning when service is needed.
