Only clean blow-by gases are then returned to the engine turbo or to the ventilation outlet. Oil droplets and soot are removed from the blow-by and returned to the oil sump. The Defender 500 uses centrifugal separation technology to clean the ventilated crankcase gases. Among others, it can be installed on construction vehicles, workboats, ferries and genset power stations.ĭefender 500 fulfills emission legislation, ensures environmental and health safety as well turbo protection for CCV applications and it is maintenance free. The unit is designed for built-on installation on off-road, marine, rail, military and stationary engines covering a wide range of industries. By protecting the turbocharger and intercooler, the Defender 500 helps maintain high engine performance and prolong engine life for closed ventilation systems (CCV). It serves as a complete engine crankcase ventilation system, including cleaning of gases and built in crankcase pressure control. The Alfa Laval Defender 500 oil mist separator minimizes crankcase gas emissions.
