Smoke Extraction Fans
Smoke extraction fans are heat-resistant special mechanical systems that expel toxic gases and dense smoke produced during a fire, keeping escape routes open. They are used mandatorily in enclosed and crowded buildings to increase life safety and preserve visibility.

Frequently Asked Questions
Is a smoke extraction fan mandatory?
It is used mandatorily in enclosed and crowded buildings for fire safety.
Which capacity should I choose?
It is determined by the volume of the space and the fire scenario. Use the table above to find the air flow (m³/h) you need, and contact us for a project-specific calculation.
Why must it be heat-resistant?
It must keep running at high temperature during a fire to keep escape routes open.
Is it used as a jet fan in car parks?
Yes, it extracts exhaust and fire smoke with jet-fan systems in enclosed car parks.
