Combined Fire & Smoke Dampers

Combined Fire & Smoke Dampers

The FSD Series Fire, Smoke and Control Damper has been specifically designed to be positioned within the duct system to prevent the free passage of smoke and fire as well as offering the added facility of air balancing control.

Combination fire and smoke dampers incorporate the features typically required by specifiers, contractors and Fire Authorities.

There are three casing variants - cases fully welded: square/rectangular, circular and flat oval. All are available in any size increment within minimum / maximum dimensions. All are suitable for low-high velocity and pressure appliactions.

Available to order are local and/or remote test panels with blade status indication; bespoke control management systems; factory fitted HEVAC approved installation frames; single and multiple assemblies.

All are manufactured in compliance with the company's quality assurance procedures.
