CCV55248 Crankcase Ventilation Elements

Crankcase blow-by is produced when combustion gases under high pressure are blown past the piston rings into the crankcase. Laden with oil, these gases must be allowed to exit the engine to prevent pressure build-up and seal failure. Blow-by oil mist can also coat engine after-coolers and turbochargers, which reduces cooling capacity and engine efficiency.

Designed for use in Racor CCV system filter housings, CCV replacement elements utilize depth-loading, micro-glass, fiber coalescing Vaporbloc™ media to remove oil contamination from engine bypass gases before they damage critical engine components and surrounding equipment. The replacement filters offer exceptional oil mist separation and are capable of coalescing vapor and contaminants down to 0.3 microns. The resulting filtered and coalesced oil is held in a hose line with a check valve, until it is released to the oil pan via a hose connection.

CCV replacement elements come available in different filtration ratings to meet the unique requirements of customers’ systems. They include:
High efficiency elements - Used for most open and closed crankcase system applications.
Ultra-high efficiency elements - Used in closed crankcase systems where the engine has higher blow-by and over 5000 hours of run time.

What is closed crankcase ventilation CCV?

Closed Crankcase Ventilation (CCV) is designed to prevent the release of harmful crankcase gases into the surrounding air by sealing off the crankcase ventilation system entirely.
