Smoke extraction motors

Never gamble with safety in tunnels! In case of fire, dispersing the toxic fumes quickly and efficiently can be livesaving. It is therefore necessary to use specialized, certified smoke extraction motors for fans in tunnels and other confined spaces.

Smoke extraction motors are typically used in two types of applications - jet fans and axial fans:

  • Tunnels
  • Single and multi-storey shopping malls
  • Single and multi-storey industrial buildings and warehouses
  • Stairways
  • Enclosed car parks
  • Theaters
  • Other locations to mitigate the effects of a fire
