Provent 200 Separator - Catch-Can from Mann Filter (By Mann and Hummel)

Closed and open cranckcase ventilation

Provent is Mann+Hummel's newest innovation for crankcase ventilation. It is specifically designed to accomodate the latest generation of turbo-charged engines and has the following advantages over existing solutions:

  • Highly efficient oil separation as a closed as well as an open system providing ideal protection for the turbocharger and other components installed downstream
  • Low pressure loss
  • Less motor oil consumption in comparison to less efficient separators or conventional open systems
  • Maintenance friendly; fittings are not removed during element maintenance
  • Universal usage; exceptional for variable flow rates
  • Flexible installation locations on the engine or in the engine compartment
  • Compact design
  • Light and robust design
  • Integrated safety feature against irregularly high crankcase pressure
  • No electrical energy required
  • Low running costs

Commercial and industrial diesel engines have a longer operational life than passenger car engines. Consequently, engine components need to be respectively more robust. One of these components, the closed crankcase ventilation system is steadily growing in importance.

For every piston stroke in a combustion engine, there are exhaust gases, which flow between the piston rings and sleeves. These gases enter into the crankcase. In turbo-charged engine applications, air can also make its way into the crankcase through the oil return pipe of the turbo-charger. These gases are generally called blow-by gases. The pressure they create lead to unacceptable pressure build-up and crankcase ventillation becomes necessary. In many countries, regulations stipulate that the crankcase ventilation must not enter the atmosphere. That is the reason why blow-by gases from car engines are redirected by so-called closed crank-case ventillation to the intake pipe assembly and burned. However, up until now, there are no standard international regulations for commercial or industrial diesel engines. Both closed and open crank-case ventillation systems are available. The open systems (without a cleaning process) direct the oil blow-by gases through a pipe into the atmosphere exposing the environment to all the undesirable gases and their detrimental environmental effects.
