DescriptionSupply and return air grille type IB with front-side horizontal orvertical pivoting air deflection blades.Frame and blades made of stove-enamelled sheet steel colourRAL 9010 (white) or of electrolytically galvanised sheet steel.Assembly parts made of electrolytically galvanised sheet steel.Fastened with screw mounting. At an extra charge, a plenumbox can be mounted (only available without hit-and-miss damp-er). The damper in the connection piece of the plenum box (byadditional charge) serves for easy air volume regulation.
