Doors, Filters, Auxiliary Elements

Auxiliary elements include various kinds of additional elements of the duct-based ventilation system.

The most important element are the access doors which facilitate cleaning of both round and rectangular ventilation ducts.

They are made of zinc-coated, acid-proof or aluminium sheet, in isolated and non-isolated options.

Other elements are filters and filtering boxes ensuring proper quality of air and access fittings, such as plugs with handles, cleanable elbows or quick coupling flanges for connecting round spiral ventilation ducts.
