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.
