Abstract

A plate-type filter element for gas filtration has a filter medium body with a circumferentially extending seal that contacts seal-tightly a first sealing surface of a filter housing extending in a filter element plane of the filter element. A sealing bracket is connected to the seal and contacts seal-tightly a second sealing surface of the filter housing extending at least partially outside of the filter element plane. A filter device has a filter housing with first and second sealing surfaces. A plate-type filter element is mountable exchangeably in the filter housing. The filter element has a filter medium body, a circumferentially extending seal, and a sealing bracket connected to the seal. The first sealing surface extends in the filter element plane; the second sealing surface extends partially outside of the filter element plane. The seal contacts seal-tightly the first sealing surface; the sealing bracket seal-tightly contacts the second sealing surface.
