FIXED BLADE GRILLE & REGISTER

FBG and FBR are grilles with a set of horizontal blades fixed at angle of 45°. FBG is a grille without opposed blades damper (OBD) and is commonly used as a wall mounted return air grille. FBR is provided with opposed blades damper (OBD) to facilitate precise air volume control.

The fixed blade return air grilles are used in cooling, heating and air ventilation. Frames and blades are made of extruded aluminium alloy 6063 to T6 Heat Treatment.

Flanges are available in 10,13,20,25 and 30mm width. Insulating gasket (optional) is fixed around the back of the frame to prevent infiltration of air between the frame and the wall. OBD are easily removable and attached to the frame by means of (S) clips to ensure tight grip and maximum flexibility. The damper is made of extruded aluminium bars. The damper opening is easily adjusted by means of a control lever that is driven by a screw driver from the front face of the register.
