The casing of the duct filter has a box construction made of galvanised steel. For easy maintenance and replacement of the filter cassette, the housing is equipped with a removable lid.
The filter cassette is installed in the housing as standard or can be ordered separately for replacement during operation. The cassette housing is made of galvanised steel or plastic profile.
