Description

Large-size, single-vent, fire resistant, specially designed for installation in RDA outlet ducts (RDA = Smoke protection pressure systems). The aim of the application is to keep safety staircases smoke-free. When a fire occurs, the exhaust damper is automatically opened by the control unit of the RDA supplied by the customer. Large-size cross sections offer a free unhindered outlet surface area for combustion gases. The closure is smoke-proof and offers fire resistance for up to 90 minutes.
