Accordion filter with a protective mask |
摘要 |
A filter element that is able to be sealingly secured in position in a filter housing, comprising an accordion fold pack. The oncoming-flow side of accordion fold pack is covered by a latticed protective mask. The protective mask is sealingly joined to all fold backs of accordion fold pack on the clean-air side. In this manner, the fold edges are protected from damage during the periodic cleaning in the face of the back-blasted air used for that purpose.
