SMOKE EXTRACTION MOTORS

Smoke Extraction Motors
Our new certified smoke extraction motors have been specially developed for buildings or construction sites with smoke control systems. This includes buildings frequented by the public in large numbers, such as discotheques, shopping centers, movie theaters, airports, enclosed car parks as well as industrial buildings, staircases, tunnels and so on. Our smoke extraction motors can even cope with high ambient temperatures safely. In the event of an accident, they reduce the heat loading on the building and keep access and escape routes smoke-free.
The double-function motors operate as follows:
  • As fan motor for operation under normal conditions
  • Operation under fault conditions as fan motor at high ambient temperatures (200°C, 300°C, 400°C) and minimum operating time stipulated according to norm
Temperature-time Classification in Accordance with EN 12101 - 3 June 2002
Class Temerature °C Minimum function duration (min) Achieved time (min)
F200 200 120 180
F300 300 60
F400 400 120
