Smoke Vent Winch

Roof vents are used to allow smoke from a fire to escape from large enclosed spaces such as shopping centres.  Our electromagnets are used to hold these vents closed against the opening force from a spring or gas strut.

By using a Geofire winch instead of an electromagnet, the vents can be automatically pulled shut after opening, making regular testing much more straight forward.  The winch also allows the vents to be opened in a controlled manner for use with temperature management systems.

Geofire roof vent winches are mains powered and include a 24v power-on clutch.  This allows the winch to free wheel when power is switched off.
