Engine air filtration expertise

Test laboratory

To be able to show our customers a comparable filtration efficiency value, we test our air filter systems according to the internationally accepted ISO 5011. The results of this test provide information on the filtration efficiency of an air filter and its contamination retention capacity, resulting in laboratory service lives. As application specifications are subject to specific local loads in practice, these laboratory service lives cannot precisely reflect the practical maintenance intervals. That is why we have additionally introduced our own in-house standard, which also provides practical results. They support our customers in the optimum design of the air filter system.

Axial and radial sealing geometries

Air filter bellows are encased in polyurethane (PUR) according to the established sealing system. During the production of air filter elements, PUR metering machines apply a 2-component adhesive under a controlled air load for the optimum seal geometry. Depending on the system, the element seals axially, i.e. with the front face, or radially e.g. with the inner or outer contour, thus also ensuring reliable application in changing weather conditions.

Glass fibre reinforced housing technology

Modern air filter housing parts are made of polyamide (PA) or polypropylene (PP). The robust design is achieved by adding a glass fibre percentage of up to 30 %.

Cyclone pre-separator technology

The efficiency of a rigid pre-separator depends to a large extent on the drawn-in nominal flow rate. The use of an intelligent pre-separator increases the efficiency of the overall system and thus increases the service life of the filter element. Longer maintenance intervals provide a reduction in costs with the use of your work machines.
