Description
Our range of smoke control dampers are suitable for installing into low to medium velocity ductwork to perform as a volume control damper, and in the event of a fire, to prevent the spread of hot or cold smoke through the ventilation system.
They can also be adapted for use in smoke ventilation shafts in both 1.0m² and 1.5m² free area sizes with matching grilles to suit.
The damper has been high temperature tested to 800°C for 120 mins.
Construction
The case is manufactured from 1.2mm galvanised mild steel, whilst the blades are double skin aerofoil section with a fish tail interlocking design from 0.7mm galvanised mild steel.
Stainless steel blades in grade 430 or grade 316 are optional.
