PRIOAIR SD-RDA-V
Smoke extraction damper
Smoke extraction damper according to EN12101-8
For use in smoke protection pressure systems according
Smoke-free escape routes
Minimal look – maximum safety
PRIOAIR SD-RDA-V
Large-format, single-leaf, fire-resistant smoke damper, specially designed to seal off outflow shafts as part of a smoke pressure system. The goal of using these is to keep safety stairwells free from smoke. In case of a fire, the controller of the on-site smoke pressure system opens the smoke damper automatically. Large cross-sections offer a free, unimpeded outflow area for flue gases. The closure is smoke proof and offers a fire resistance rating of over 90 minutes.
PRIOAIR SD-RDA-V is classified for vertical installation in walls and ducts and thus has the classification vedw (d = duct smoke extraction duct, w = wall, wall – part of the smoke extraction duct) required for installation in shaft walls and offers an outflow area of up to 1.74 m² at pressure stage 2 in the largest dimension.
