Open or closed filter systems for crankcase ventilation

Emissions of oil vapor and oil dripping from motors are caused by high pressure gases and oil leakages around the piston rings. This contaminates the engine and the environment. Crankcase ventilation systems provide a reduction of contaminants and protect the environment.

Most diesel engines today do have closed crankcase ventilation systems – where the gases are returned to the engine’s air intakes and the oil is returned to the engine pump. Open crankcase ventilation systems reduce contamination before the air is vented into the atmosphere.

  • Fleetguard CCV Closed Crankcase Ventilation system protects the engine and provides the best solution for emissions removal – helping to reduce oil consumption by eliminating mist, aerosol vapors and oil drip in the engine compartment.
  • Enviroguard is an open crank case ventilation system that provides optimal contamination removal before the air is vented into the atmosphere.
  • EcoVent is a crankcase ventilation system for closed circuits at large high-speed engines.
