An air filter has a filter housing having a raw air inlet and further has a filter element arranged in the filter housing. The filter element has a filter medium body and an end disk with a central primary air passage and a secondary air passage. The filter medium body annularly surrounds a longitudinal axis of the filter element and separates a raw side in the filter housing from a clean side inside the filter element. The filter housing has a primary air outlet communicating through the primary air passage with the clean side of the filter element. The filter housing has a secondary air outlet communicating through the secondary air passage with the clean side of the filter element. The secondary air outlet communicates with the secondary air passage through a channel arranged at the filter element, wherein the channel surrounds the primary air passage annularly and coaxially.

Air filter comprising a primary air outlet and a secondary air outlet and filter element for same

A filter element has a filter medium folded in a star shape that surrounds annularly a longitudinal axis of the filter element and is flowed through radially from exterior to interior. The filter element has a primary air passage and a secondary air passage. In the filter medium, a cutout is formed that penetrates a plurality of folds of the filter medium. A passage socket at which the secondary air passage is formed extends through the cutout. An air filter provided with a filter housing having a raw air inlet, a primary air outlet, and a secondary air outlet, has such a filter element that separates in the filter housing a raw side communicating with the raw air inlet from a clean side. The primary air outlet communicates through the primary air passage and the secondary air outlet through the secondary air passage with the clean side, respectively.

Air filter with a primary air outlet and a secondary air outlet as well as filter element therefor

An air filter element () for insertion into an air filter housing, comprising an intake surface (), a discharge surface (), a filter medium (), and a filter element-retaining device () which extends along at least a section of the periphery of the filter medium (), between the intake surface () and the discharge surface (), and which includes a retaining arrangement () that radially projects from the filter medium ().

Air filter element with retaining geometry

Disclosed is an air filter element () for insertion into an air filter housing, comprising an intake surface (), a discharge surface (), a filter medium (), and a filter element-retaining device () which extends along at least a section of the periphery of the filter medium (), between the intake surface () and the discharge surface (), and which includes a retaining arrangement () that radially projects from the filter medium ().

Air filter element having a specific retaining geometry

Disclosed are an air filter element, a filter housing, and an air filter in which the air filter elements have a high filtering capacity and a long service life by increasing the filter surface of an air filter element taking into account structural requirements for the air filter housing.
