Smoke damper, horizontal

Horizontal smoke damper

For closing openings in discharge shafts

Opens automatically in case of fire

Description

Large format, single leaf, fire resistant smoke control damper especially designed for installation in air release shafts of RDA (RDA = Smoke protection pressure systems). The aim of the application is to keep safety staircases smoke-free. In case of fire the smoke control damper is opened automatically by the controls of the on-site RDA. Large-format cross-sections provide a clear, unobstructed air release area for fire gases. The closure is smoke-tight and provides fire resistance for 90 minutes.
