Volume Control Dampers
Every component. One supplier.
From the gear that drives the blade to the base profile that frames the opening - Vivant supplies every part of a volume control damper assembly. Individual coded components or complete kits.
How a VCD Works
A multi-blade operational layout engineered to modulate airflow via unified physical link rotation structures.
Handle (NY DMHD / GI DMHD)
Operator turns the handle
Gear (NY DMGR)
Gear translates handle rotation to blade movement
Blade (AL DMBL)
Blade rotates from fully open to fully closed
Airflow
Modulated from full to zero
Damper Profiles
Heavy-gauge structural components extruded from high-performance aluminium alloys for dimensional structural stability.
