Crankcase Ventilation

Good crankcase ventilation removes emissions and reduces oil consumption. But all CV filters are not alike. Some cheap systems can melt under high temperatures, which can cause catastrophic engine damage. Our quality CV systems stand up to heat to protect your engine. Why take a chance on anything other than Fleetguard?

Four Great Reasons to Choose Fleetguard for Crankcase Ventilation

Meets Emission Standards
EPA-verified to provide superior aerosol filtering of crankcase emissions, or “blow-by,” which are the result of high-pressure gasses and oils escaping around piston rings and venting to the atmosphere.

Reducing Oil Consumption
Eliminates mist, aerosol vapors and oil drip in the engine compartment. Filters up to 99% of oil drip from blow-by.

Lowers Maintenance Costs
Service intervals are up to 3 times longer than the competition, reducing engine downtime and maintenance costs while extending engine life. Plus, less down time means greater productivity for your equipment and your business.

Tough, Quality Parts
Our open CV filters are made of a durable polymer blend, which stands up to heat better than cheap polypropylene media used by some competitors and reduces the risk of catastrophic engine damage.
