Francis HTF temperature exhaust fan is a series of products, performance of new fans between axial and centrifugal fans between the inlet silencer equipped with a current collector, the outlet is equipped with deflector, and is designed into the second gas, help to reduce the ambient temperature of the motor. Temperature exhaust mixed flow fan with high efficiency, energy saving, low noise, compact, light weight, small size, reliable, easy to install exhaust fan manufacturers, may run one hour at 300 ℃ environment can be different according to senior civil requirements, with variable speed or multi-speed drive form the heart reaches one machine (ie, when used through ventilation and fire high-temperature exhaust) purposes; airfoil axial flow into (HTF (GYF) -I, II) and Francis HTF (GYF) -IG, also making rooftop silencer type. 2. High efficiency: This series of axial fan using advanced CAD software by the multi-objective optimization design of new products developed in the test shows that fan efficiency greater than 80%, some big machine number greater than 85%, and has a flat efficiency curve characteristics conducive to energy conservation; 3, easy installation, covering less centrifugal fan: The fan base in the form of an axial flow fan or mixed flow fan, direct pipe connection or wall mounting with the wind, the installation can be vertical or horizontal form. Considerably reduced footprint. HTF (A) fire temperature exhaust axial fans using advanced CAD-aided design system, exhaust fans, is the more optimized design developed new products with high efficiency characteristics curve flat, conducive to energy conservation. Optional molded axial flow impeller, built high temperature 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. exhaust fan price, widely used in high-rise building fire situation, drying room, underground garage, subway, tunnels and other smoke and send row ventilation. Press GA211-1999 Fire fan high temperature test methods, can run more than 100 minutes of continuous high temperature at 400 ℃, medium temperature at 100 ℃ continuous operation 20 hours / times without damaging the exhaust fan reports, it has been the major cities nationwide fire departments 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.
