HS35 Serie Bag Filter

HS35 serie bag filter  is used as a pre- or fine filter in air conditioning systems among other thingsair treatment cabinets, air conditioning systems, public areas, and as a pre-filter in cleanrooms and the pharmaceuticals industry.
The filter media, made from both polymer and glass fibres, are assembled in a robust plastic, steel or aluminium frame. Bag filters have ultrasonically welded leak-tight bags, assembled in a polystyrene frame. Bag filters are resistant to temperatures of up to 70°C.

The aluminium frame is a new introduction for AFPRO filters – its advantage is its great stiffness and the detail or the finish level. With the new aluminium frames in combination with the aerodynamic finishing strips, the filters are even simpler to install, and they will have a lower resistance throughout their lifetime
