The PASSAGE is an innovative remote smoke control damper allowing complete freedom with regard to dimensions of smoke control shafts. The net passage is infinitely adjustable so that required flow rates and/or air speeds can be set as required at the yard. The PASSAGE is developed in compliance with the European product standard EN 12101-8 and tested with cover grille according to standard EN 1366-10. The product is fire resistant for 120 minutes and guarantees minimum pressure loss.
Smoke evacuation shutters and dampers are suitable for use in ventilating protected lobbies, venting to shafts either naturally or mechanically. They open to evacuate smoke in emergency situations whilst maintaining fire resistant integrity in standby position.
