Cyclone car park induction jet fan

Colt Cyclone is designed to reduce the concentrations of polluted air and to assist with the extraction of smoke trapped in car parks, in the event of a fire. It is a low profile, high velocity induction fan, which controls air movement in underground service areas and car parks, directing polluted air towards the extract positions. It is tested and certified to EN 12101-3.

Cyclone incorporates a backward curve centrifugal impeller with a high temperature external rotor motor rated at 300°C for one hour.

These kinds of fans use tunnel ventilation technology to eliminate the need for costly and bulky ductwork. Compared to ductwork systems, this may save car-parking spaces, reduce running costs and noise, and make the car park a lighter, less cluttered environment.
