Description

Mann+Hummel Open/Closed Circuit Provent

Crank Case Filter Assemblies

 

The Mann + Hummel Open/Closed Circuit Provent is an oil separator for closed and open crankcase ventilation.  Crankcase blow-by is produced when combustion gases are blown passed the piston rings into the crankcase. As these blow-by gases pass though the crankcase, they become contaminated.  Crankcase Ventilation Filters remove these contaminants so the exhaust can then be allowed to vent to:

CLOSED CIRCUIT – The exhaust from the outlet is routed to the inlet side of the turbo
OPEN CIRCUIT – The exhaust from the outlet is vented to atmosphere

 

The development of the whole MANN+HUMMEL ProVent product family was directed towards the newest generation of industrial diesel engines. ProVent sets the standard for crankcase ventilation and offers important advantages:

  • Highly efficient oil separation through high performance media
  • Excellent protection for the turbocharger and components fitted downstream
  • Integrated safety feature against irregularly high crankcase pressure
  • Low installation height to oil level possible through low pressure drop
  • Lower engine oil consumption in comparison to less efficient separators or to conventional open systems without an oil separator
  • Easy to service through quick access and protection against incorrect insertion of replacement element
  • Suitable for universal use with different flow rates
  • Excellent flexibility for choice of installation position and ports
  • Compact and light design, but robust
  • No auxiliary power required
  • Extremely reliable, also at low temperatures
  • Very low running costs
  • All ProVent products are suitable for use with open or closed crankcase ventilation
