Geofire > Products > Smoke Vent Automatic Winch

The Geofire range of powered winches offer a compact solution to the problem of opening roof vents in large buildings.

The slim-line design allows the winch to be fitted unobtrusively in the vent frame work. A powerful 230V motor provides ample closing force via cables fitted to the vent.

Once the vent/fire door retainer is closed the winch locks in position with a 24 V brake.

When power to the brake is cut, the winch releases allowing the vent to open under the action of gas struts, etc. When power is returned to the winch, it automatically pulls the vent back to a closed position.
