Regulating dampers with EPDM gasket

Photo of product DARL

The DARL regulating damper with EPDM gaskets at both flange
connections has been designed for cladding with up to 50 mm
thick insulation.

The damper closure is pivoted on separate square rods.
The square rod pivots are replaced with a single solid bar in
regulating dampers of diameter 450 mm.
The damper closure position can be read on the 0° to 90° dial of
the control handle. Closing the damper closure allows 20% of
the rated airflow to pass. The damper closure opening ratio can
be fixed with a screw.
