Along with our ventilation grilles you can order an airflow control element (damper), mounted directly on the grille frame. The grilles can be mounted directly to the wall barrier with screws, by using an assembling frame with an invisible clip fastener, or to a plenum box.
These products are made of aluminium, anodised aluminium, galvanised steel or stainless steel. Additionally, we offer paint covers in any RAL colour.
The STR-type grilles are designed for direct installation in round ducts thanks to their specifically shaped face frame. The KS-type grilles are used as terminating elements for round ventilation ducts or spiro pipes. The grilles can be fitted with an assembling frame, equipped with an EU3 filter (or a different class upon request). Rectangular grilles can be installed in a round duct using the NDS cap.
Screen deflectors can be attached to the grilles (used to improve airflow). Deflectors come in two variants: with a clearance of 35% or 58%. They are made of galvanised steel. These products are mounted directly onto the grille. The grilles are designed with plenum boxes in galvanised steel, stainless steel (1.4301) or acid resistant steel (1.4404).
Accessories for ventilation grilles include: plenum boxes, dampers (GP, GA, GSN, GT, GM, GC), screen deflectors (L01, L02), NDS sockets for spiro pipes for installation of rectangular universal grilles, assembling frames (RM, RMZ) and RM(Z)+F assembling frames with a filter.
