For duct or wall mounting (type KG-Q) or installation in round pipes (type KG-R) in supply air and return air installations of cinemas, shopping centres, halls and underground car parks.

The small mounting depth prevents air vortex formation on the front face, as a result of which air is applied evenly to the whole grille surface. The susceptibility of the grille to corrosion is greatly reduced by the absence of weld spots during manufacture. With hit-and-miss damper for setting the air flow rate.

• Ceiling or wall installation, with plenum box or directly into ducts. Solid fastening with screws on a flat frame.
• The clinch joining technique without producing welding spots gives better anticorrosive protection.
• Compact unit consisting of grille and hit-and-miss damper.
• Material: galvanised sheet steel, painted sheet steel, aluminium anodised in natural colour, stainless steel 1.4301 (V2A).
• Option of a profiled cover frame that conceals the fixing screws.
