AIR CLEANER SYSTEMS
Perfect integration multifunctional products
Our core competence in the development of air filter systems includes the filtration, the flow optimization, NVH, styling, and integration of various functions. Continual further development in all these areas enables us constantly to set new standards. The results are competent solutions for many-faceted requirements.
MANN+HUMMEL air filter systems also offer innovative solutions in the field of gas filtration. Examples of applications include HC-Adsorption – relevant to the forthcoming LEV2 emission legislation in the USA – or the pollutant gas filtration in fuel cell applications. Flexible and innovative – air filter systems for commercial vehicles.
MANN+HUMMEL has developed a flexible modular system with metal-free filter elements & system solutions adapted to meet customers’ specifications that saves development time – the New Air Filter Generation (NLG).

FILTERS FOR LIQUIDS
Modular concepts - for transmission oil filters, fuel and motor oil filter systems.
The Liquid Filter Systems Business Unit concerns itself with the filtration, separation,
and tempering of liquids that are used in automobiles. This includes mainly the development & production of filter systems for fuel, engine oil, and the transmission oil circuit.
The filter systems that are produced can be equipped with various additional functions. In the case of oil filter systems these are, for instance, oil/water heat-exchangers, valves, oil venting devices, or load-bearing functions integrated into the housing. In the field of fuel filtration, heating and cooling systems, sensors for water recognition, and water drain functions are used.
Transmission oil filters and oil centrifuges that separate solid particles from the engine oil complete the product range of this Business Unit. |
PRELINE FILTERS
The injection pressure in modern diesel engines has risen continuously in recent years due to higher performance requirements. The injection systems used have very high requirements regarding cleanliness of the fuel.This means the fuel should contain hardly any particles and practically no water (condensate).
MANN+HUMMEL uses high performance multigrade media for the filtration of the fuel.
The MANN+HUMMEL PreLine® series separates more than 93 % according to ISO 4020 of water present in the fuel and so fulfils the requirements of leading injection system producers.
The perfectly matched interaction between the PreLine® pre-filter and the MANN+HUMMEL main filter offers maximum protection for the sensitive injection system and contributes to the economic running of your engine.

CRANKCASE VENTILATION
ProVent® is MANN+HUMMEL's newest innovation for crankcase ventilation. It is specifically designed to accommodate 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
