Automatic Fire Door

Essential for use with all sizes of refuse and linen chutes.  An automatic fire door gives a vital 1 hour fire protection from any fire in the refuse or linen room.
Hardall automatic fire doors are built to an exceptionally high standard of precision and safety.  Operation is by 2 powerful springs pulling against a 70deg.C fusible link .  In the event of a fire the fusible link breaks and the springs pull the shutter door across the chute.  Hardall fire doors normally have a 1 hour fire rating but are also available with a 2 hour rating where specified.
