Quality Assurance system assessed to BS EN ISO 9002.
4 hour fire resistance.
Lead time on all rectangular fire dampers is 5-7 working days.
Casings are manufactured from 1.2mm galvanised mild steel. Blades are specially rollformed from 0.8mm galvanised mild steel as standard. Curtains held outside airstream (top of unit in the image).
"Why would I need an installation frame?"
When exposed to high temperatures the steel casing of the damper will expand. In the absence of a frame, this would cause the mechanism to jam, preventing the damper from closing. The frame provides a cavity between the damper body and the brickwork. This allows for expansion and ensures the damper closes correctly.
All fire dampers are to be installed in accordance with the manufacturer's instructions; a copy of which can be found here.
