Rectangular regulating damper

Consists of a duct with trapezoid corrugations and a turning blade. Blade angle can be adjusted 0–90° using the knob in the cup, and blade angle is read from an embossed scale on the edge of the cup. Locking is done by two Pozidriv screws (PZD2).

The damper is provided with a joining profile at each end. The length is normally b + 10, but the damper can also be ordered in special lengths.

The cup allows an insulation thickness of 50 mm. If thicker insulation is needed, add the special insulation cup IK to the damper.

Maximum size for the damper is 600 × 600 mm.

LKSR is equipped with joining profile type RJFP.
