When it comes to protecting turbocharged diesel engines from crankcase emissions, Racor's patented Closed Crankcase Ventilation (CCV) Filter System provides superior oil coalescence and crankcase pressure control under the most severe conditions. As part of the broader air filters and crankcase ventilation category, Racor's specialized filtration solutions address a critical challenge: preventing contaminated blow-by gases from damaging turbochargers, after-coolers, and air intake systems while meeting increasingly stringent emissions regulations.
Vaporbloc Technology: The Heart of Racor CCV Systems
These filters use advanced Vaporbloc media to protect engine components and maintain cleaner operation in various Racor CCV systems. The proprietary depth-loading, micro-glass fiber Vaporbloc™ media sets Racor apart in the crankcase ventilation market, offering high efficiency oil separation down to 0.3 micron particle size. This exceptional filtration capability ensures that oil mist is effectively removed from crankcase emissions before they can contaminate the combustion air intake or escape into the atmosphere.
Comprehensive Product Line for Diverse Applications
Racor offers multiple CCV series designed to handle varying engine sizes and applications. The systems are compatible with multiple Racor CCV filter housings including 4500 to 12000 series, providing solutions for engines ranging from small marine diesels to heavy-duty industrial power plants. Especially suited for turbo-charged diesels, Racor CCVs provide superior oil coalescence and crankcase pressure control under the most severe conditions, making them ideal for marine, construction, agricultural, and on-highway applications.
Engineering Features That Deliver Performance
What distinguishes Racor crankcase ventilation systems is their intelligent design. CCV units feature a unique crankcase pressure regulator with an integral bypass valve that protects against crankcase over-pressure and under-pressure, thus preventing damage to seals and oil loss. The systems operate reliably within a wide temperature range from -40°F to 240°F, ensuring consistent performance regardless of climate conditions. Additionally, Racor CCV4500 units include stainless steel latches for tool-less element change, simplifying maintenance and reducing downtime.
Environmental Benefits and Emissions Reduction
Beyond engine protection, Racor's crankcase ventilation filters deliver measurable environmental benefits. They reduce NOx and hydrocarbon emissions by lowering combustion temperatures, helping equipment meet modern emissions standards. In closed systems, the cleaned and filtered gases are routed back to the inlet of the turbocharger to be burned in the engine, preventing oil-contaminated vapors from escaping into engine compartments or the atmosphere.
Low Maintenance, Long Service Life
One of the most attractive features of Racor's air filtration and crankcase ventilation products is their minimal maintenance requirements. The only routine maintenance required for the CV/CCV Crankcase Ventilation Systems is filter replacement, with typical service life of the high-performance filter in diesel applications being 750 hours. This extended service interval reduces operating costs and keeps equipment running with minimal interruption. The systems are available with high, low, and ultra-density media options for varied applications, allowing operators to match filter density to specific operating conditions and contamination levels.
