The challenge facing the development of air filter elements lies in the installation space prescribed for them, which is often very small and requires flexible geometrical shaping of the elements whilst at the same time meeting stringent requirements for filter performance.

The new inline filter system from MANN+HUMMEL with its highly compact air filter elements meets these requirements. The compact air filter elements consist of a large number of channels arranged in parallel with one another and alternately enclosed. Inside the air stream enters from the raw air side and is conducted through the filter paper so that it can flow out again through the neighboring open channel on the pure air side.

Another MANN+HUMMEL innovation is the completely synthetic filter medium Micrograde N. Its distinctive feature, in comparison with conventional cellulose media, is its far higher dirt absorption capacity and a vastly improved filtration performance, which makes it possible to lengthen its service life or to reduce installation space.

With the aid of MANN+HUMMEL production technology and the outstanding filtration performance of our media, MANN+HUMMEL air filter elements can be adapted efficiently to fit the installation space available in passenger cars and commercial vehicles.

True to its slogan “Any shape any size” MANN+HUMMEL sells filter elements in various different shapes and sizes including oval-conical, trapezium, or stepped, and even filter elements with a sealed aperture.
