HTF series fire temperature exhaust fan designed specifically for high-temperature exhaust. Equipped with high-temperature fan motors, totally enclosed motor built, and a special motor cooling system to ensure safe use of the electric motors at high temperatures. By objective optimization design, the company's HTF temperature exhaust fan fire, the sentence has excellent high temperature performance, high efficiency, low noise, reasonable structure, small size and easy installation. Installed on horizontal, vertical, lifting can be. 1. centrifugal fan wind chassis, the required electrical power is the condition to be determined, together with proper mechanical loss reserves, it is not a required air full of power, such as the fan outlet is not then pipe or add external resistance and empty running, the motor burned danger, for safety reasons, the valve should be added at the fan outlet or inlet line, starting off the fan, will run slowly open the valve, reaches a predetermined condition so far, and pay attention to fan current exceeds a predetermined value. 2. The fan allows full pressure start or step-down start, but it should be noted that the current full voltage starting time of 5 to 7 times the rated current exhaust fan brand, voltage starting torque is proportional to the square of the voltage, when the lack of grid capacity When the exhaust fan installed, should step-down start. (When the power is greater than 11KW, should adopt the step-down start). HTF (A) fire temperature exhaust axial fans using advanced CAD-aided design systems, is the more optimized design developed new products with high efficiency characteristics curve flat, conducive to energy conservation. Optional molded axial flow impeller, offer built-in high-temperature exhaust fan motor, arranged a special motor cooling system. Use two-speed motor direct-drive, to one machine (that usually send row when high-temperature exhaust ventilation and firefighting), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, high efficiency, small size, easy installation (horizontal, vertical, lifting can be), etc., are widely used in high-rise buildings, drying room, underground garage, subway, tunnels and other occasions to send fire smoke and exhaust ventilation . Press GA211-1999 Fire fan high temperature test methods, can run at 400 ℃ more than 100 minutes of continuous high temperature, medium temperature at 100 ℃ continuous operation 20 hours / times without damaging the exhaust fan, it has been the major city fire department authorized use. Fans of the series may use the occasion of the installation requirements, peripherals silencer box, made HTF (A) -X box-shaped exhaust fan the fire.
