Louver Dampers

Multi-Vane dampers with opposed linkage provide the best alternative for throttling control. These dampers can also be supplied with seals to minimize leakage along with their modulating capability.

Multi-Vane dampers with parallel linkage are an excellent way to provide isolation where space is at a premium. This type of damper is often used on fan inlets to aid fan performance.

Control Equipment multi-vane dampers can be supplied for light weight applications such as system balancing and industrial ventilation, or for heavy duty applications such as gas turbine exhaust and high volume flow control.
