Abstract:
A filter fan includes a basic housing with a frame, wherein the frame is equipped with a quick fastening device in the form of spring-elastic clips. In order to prevent air and/or moisture from penetrating into a housing, the frame extends continuously and without openings around a circumference. The clips are molded onto the frame.
