Discover unmatched safety with Changli's IEC low voltage smoke extraction motors
Smoke extraction motors play a critical role in keeping tunnels safe. In the event of a tunnel fire, lives depend on the ability of extraction fans – and the electric motors driving them – to disperse toxic fumes and smoke quickly and efficiently. Smoke extraction motors must be capable of withstanding the high temperatures generated in fire zones and continue to work reliably under these extreme circumstances.
Product Overview
Smoke extraction motors are typically used in two types of applications - jet fans and axial fans - for both comfort ventilation and extreme cases by fire.
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
