backward Curved Fans for Smoke Extraction Systems

Method of smoke extraction by means of fans certified for work at temperature during a specific period of time according to classification and certification. This method is habitually applied in blocks, shopping centres, tunnels, car parks and other large buildings and with large open areas, also in industrial buildings with a high risk of fire and for smoke extraction in industrial kitchens.

Backward curved impellers are generally more efficient that their forward curved counterparts. Our collection of smoke extraction backward curved fans are suitable for use outside of the danger zone and are often available as standard and special specifications for the emergency control of smoke.
