Reinforced round shutoff damper

The DASL-B shutoff damper with EPDM gaskets is designed for cladding
with up to 50 mm thick insulation. The damper closure angle range is
0˚ to 90˚ and can be read on the handle dial.
The differences in design regarding a standard DASL are: additional folding
in the housing, reinforcements on the damper blade, thicker hinge rod (12x12mm),
brass bearings. Used materials provide temperature resistance up to 110˚C
(200˚C for DAS-B without gasket).
