Smoke Extraction Motors

Reliable ventilation even at high temperatures

General description

The certified smoke extraction motors have been specially developed for buildings or construction sites with smoke control systems. 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.

Smoke extraction motors have two important double functions:

Standard operation (fan):

  • Ventilation or extraction under standard conditions, for instance KT -20 ... +40°C

Operation under fault conditions (fire):

  • Maintaining evacuation and access routes free of smoke

  • Facilitate firefighting by creating a smoke-free layer

  • Preventing / delaying fire flashovers

  • Protecting devices and equipment

  • Minimizing the thermal stress of components

  • Extracting thermal decomposition products and hot gases quickly from the fire location, therefore reducing the subsequent damage caused by fire
