This damper features EPDM gaskets at both flange connections and is designed to accommodate cladding with insulation up to 50 mm thick.

It is a suitable option for ductwork systems where full airtightness is not required. The dampers closing position is indicated on a control handle dial ranging from 0 to 90, and the opening angle can be locked in place with a screw.

All standard DASL dampers are constructed from galvanized steel sheet.
