Racor CCV Systems - In a robust, compact package, the patented Racor Closed Crankcase Ventilation (CCV) Filter System provides superior oil coalescence and crankcase pressure control under the
most severe conditions. The only routine maintenance required for the CCV system is filter replacement. Typical service life of the high performance filter in diesel applications is 750 hours. Some variations in service life occur depending on load profile,
engine wear condition, flow and aerosol mass concentration
of crankcase emissions, and soot concentration.
