DASH dampers are among the most budget-efficient solutions
for air flow control in round ductwork systems. The safe edges
at the damper ends protect against accidental injury during
the installation process.
The wing nut can be tightened to set the control lever in place
at a specific opening angle. The dial of the control handle shows
the damper closure / opening ratio. This damper is designed for air
ducts in diameters of 80 to 315 mm and made from galvanized steel sheet.
