Smoke control lobby damper for naturally and mechanically ventilated applications.
Application
Designed for internal application in shafts within multi-level buildings with a natural (stack effect) or mechanical ventilation system.
For smoke evacuation and control within lobbies, suitable for dry wall or masonry/ concrete construction.
Description
The LDN Series Lobby Natural Ventilation Smoke Damper consists of two parts, the damper within a sleeve and a grille room side for ductless applications. The main sleeved damper with peripheral flange allows it to be fitted flush into the builder's prepared aperture.
The fitted internal actuator is used to drive the damper blades from the normal closed position to the fully open position on receipt of a signal from a fire/smoke control and detection system. The horizontal blade grille has been designed to maximize the airflow with minimal pressure loss and is affixed to the damper with concealed colour-matched fixings.
