The DAS-PVC dampers are designed for cladding with up to
30 mm thick insulation.
The DAS-PVC shutoff damper is a good choice when the ductwork
closure does not have to be fully 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.
The product has safe edges.
