Multivane (Louvre) Dampers

are available with various configurations with respect to vane rotation, frame splitters (incorporating central bearings), linked or independently actuated vanes and single or double drive systems.

Vane rotation is either direct (parallel) or opposed. The latter is ideal for flow control as disruption is minimal whereas direct rotation is better suited for open/closed duty or positioning where the vanes could be used to improve flow around duct bends.

The greater the number of vanes the better the control but pressure loss across the damper increases and sealing efficiency is reduced due to seal periphery.


We can design and manufacture a wide range of multivane and louvre dampers for a wide variety of applications in any size required.
