The aluminium damper blades and other prefabricated
accessories for DSQW-A dampers allow shop and on-site
fabrication.
The blades are dimensioned to enable quick assembly, and the gaskets inside the frame angle sections
and on the damper blade provide air tightness class 2. The
rigid sections and the sectional prefabrication design allow
building dampers up to 3000 mm in width.
