CCV AND CV SYSTEMS

ENGINE SPARES & GEARBOXES

The Parker Racor CCV (Closed Crankcase Ventilation) and Racor CV (Crankcase Vent) systems help the environment by eliminating oil mist from engine crankcase emissions. All engines have blow by gas that passes from the combustion process into the engines case. This will mix with the lube oil, and can be forced out of the engine through the breather system. Racor CCV and Racor CV breather systems work by controlling the crankcase pressure, separating the oil and returning

it to the sump. More sizes available online at www.asap-supplies.com Available with 3 different element grades, for the following applications: 06 Grade - Medium density (diesel applications only) 08 Grade - High density (diesel and petrol applications) 10 Grade - Ultra high density (diesel and petrol long life applications)

Racor offer a rough guide for selecting the right crankcase vent system for your engine. This is to take the rated horsepower and divide by 40 for closed crankcase systems or 20 for open crankcase systems. This will give the rough cubic feet per minute flow rate you will require from your crankcase system. New engines = rated horsepower divided by 40 (or 20) = CFM. Worn engines can produce twice as much blow-by.

As a guide, Racor crankcase application is determined by crankcase flow in CFM. CFM on new engines is low but as the engine wears, the CFM increases.
