PRIODOOR ETX RDA H
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.
