Marine - Engine Air Filtration

Environmental concerns and legislation to control crankcase emissions have increased significantly. Crankcase blow-by is produced when combustion gases under high pressure are blown passed the piston rings into the crankcase. As these blow-by gases pass though the crankcase, they become contaminated. Racor’s Crankcase Ventilation System removes these contaminants.


In closed environments like generator sets and marine engine rooms, damage from oil mist created by the blow-by gasses to surrounding equipment, such as radiators, electronic control panels, and other engine components, can cause hazardous conditions, down time, and expensive maintenance. It is imperative that oil mist be removed from the crankcase emissions prior to introduction into the engine air intake in closed breather systems.


In a robust, compact package, the patented Engine Mobile OE Division CCV (closed crankcase ventilation) filter provides superior oil coalescence and crankcase pressure control under the most severe conditions. The only routine maintenance required for the CCV 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, aerosol mass concentration of crankcase emissions, and soot concentration.


The Engine Mobile OE Division Marine Air Filter/Silencer removes contaminants introduced into the air from both outside and inside the vessel. Sand, salt, carpet fibers, and other contaminants are trapped in the oil-impregnated Vaporbloc™ filter media. Turbo noise is reduced by the unique design of the housing. An integral hose connection on the housing routes the clean blowby from the CCV back into the engine.
