[CV4501-04R]Parker Racor CV4500 OPEN SYSTEM- NO BYPASS

In an open system- the crankcase breather is connected to the Crankcase Ventilation (CV) filter assembly. The CV outlet is open to atmosphere. This configuration is simple to install and is an effective oil mist removal system for applications whichallow crankcase venting to atmosphere. There may be some visible blow-by gases present from the CV outlet. 

 

The only routine maintenance  equired for the CV system is filter replacement. Typical service life of the highperformance 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. 

 

CV units are designed to handle various crankcase flow rates up to 50 CFM. Traditionally- the crankcase flow rate can be calculated as follows: rated horsepower ÷ 20 = cubic feet per minute (CFM). This formula can only be used as a guide since recent improvements in piston design have produced engines with higher horsepower and lower blow-by flow rates. The blow-by flow rate of a worn engine- at time of overhaul- is generally double the flow rate when the engine is new. The flow

rate of a worn engine is factored into the formula.
