NonInsulated Shut-off Damper

The Shut-off dampers are designed for cladding with up to 50 mm thick insulation. They are a good choice when the ductwork closure must be airtight. The damper closure position can be read on the 0° to 90° dial of the control handle. The damper closure opening ratio can be fixed with a screw. Standard dampers are made from galvanized steel sheet. Others are available on request.
