MANN+HUMMEL ProVent
Oil separator for closed and open crankcase ventilation
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 |
All the available units can be fitted to Diesel and also petrol engines, in petrol engines they can be used in place of after marker catch cans, using this unit the breather system returns the oil carryover to the engine. Stops the build up of deposits in cam covers amongst other advantages. In a TDI application it would go between the Crankcase Breather and Turbo Inlet Pipe to catch any oil whist maintaining the closed breather system. This will reduce the amount of oil found in your Intercooler Pipework, Turbo Housing and TIP Pipe.

Crankcase ventilation - variety and expertise
In internal combustion engines, an oil-laden leakage gas known as the blow-by is produced in the crankcase.
The blow-by must be returned during the combustion process, which is achieved by closed crankcase ventilation (CCV) systems. CCV systems also separate and return the oil to the crankcase and regulate pressure in the crankcase.
MANN+HUMMEL can supply all the components and systems involved in crankcase ventilation, including:
• Oil separators
• Pressure regulating valves
• Heating pipes
• Valve technology (anti-drain valves, PCV valves, ventilation valves)
• Integration of crankcase ventilation into cylinder head covers or other integrated solutions
With increasingly strict emissions legislation, the requirements for oil separation have increased continually over the past few years. Emissions-related engine components such as exhaust turbo chargers, charge air coolers and charge air sensors must be protected against performance degradation from oil contamination. MANN+HUMMEL provides various designs for oil separation, ranging from inserted or non-inserted inertial separators, such as cyclonic or impactor separators, to the ProVent fibre separator for HGV and industrial use.
The ProVent system integrates a powerful oil separator element and a pressure regulator element, both characterized by their robust and light-weight designs. ProVent protects the turbocharger and the downstream engine components from the build-up of oily deposits that diminish performance. This commercial concept is designed for industrial engines with a power of up to approx. 1250 kW and can cover volume flows of approx. 10 to 1000 liters per minute (l/min) blow-by.
The series is complemented by safety valves that allow for multiple applications.
