HTF series high temperature fire fighting smoke exhaust axial fan design by using CAD Technology of multiple-target optimization. adopts contour forging twist wing form mixed-Flow impeller, fully enclosed built-in the high temperature motor, and special motor cooling system. The fan is made of direct drive double-speed motor,to achieve a fan of two usage(Usually the supply and exhaust ventilation,and fire fighting high temperature smoke exhaust). the mating electric cabinet can remote automatic control. They have the advantages of high heat-resistance, large air volume and high pressure.The fan is widely used in high buildings, drying room, underground parking, subways, tunnels, and fire fighting smoke exhaust ventilation. According to the test method of GA211-1999 for the fire resistance to high temperature fan. In the 350℃ high temperature environment, the fan can continuous operating more 100 minutes. In the 120℃ high temperature environment, the fan can long-term operation.
