Filter cartridge

Installing a filter cartridge on the outdoor air duct inlet helps extend the ventilation unit filter life and ensures no insects, leaves or other debris make their way into the ventilation unit.

The filter cartridge includes a G4 coarse dust filter. Filter cartridges are available for 125 mm, 160 mm, 200 mm and 250mm ducts. This option is mandatory if a preheating/cooling calorifier is installed in the system.
