HTF (A) series fire temperature exhaust axial fan Overview and Features 1, HTF (A) fire temperature exhaust axial fans, the basic form of an axial flow type structure, with high temperature motor, with a special motor cooling system. With excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation and so on. 2, HTF (A) fire temperature exhaust axial fan through the "National Fire Equipment Quality Supervision and Inspection Center" qualified, the performance of the leading domestic level, through more than 30 provinces nationwide fire department certification. The fans sold in Beijing, Tianjin, Shanghai, Chongqing, Zhejiang, Guangdong, Jiangsu, Shandong, Henan, Hebei, Anhui, Hunan, Sichuan, Liaoning, Hubei, Shaanxi, Jilin, Inner Mongolia, Shanxi, Guizhou, Heilongjiang, Jiangxi, Yunnan, Shenzhen and other provinces (municipalities) and autonomous regions. 3, high temperature performance: Fan tested in accordance with the Fire Code standards GBJ45-82 fan with a unique design, high temperature motors built, configured motor cooling system can operate continuously under conditions of high temperature 300 ℃ more than 100 minutes, temperature 100 ℃ condition Continuous 20 hours / times without loss, widely used in high buildings, oven, underground garage, tunnels and other occasions; 4, for a wide range: according to different requirements of senior civil use of variable speed or multi-speed drive form, in order to achieve a dual-purpose (ie, through ventilation and fire are common high-temperature exhaust) purposes; airfoil into axial flow (HTF (A) -I, II) and Francis HTF (A) -IG, also making roof type silencer type. 5, High Efficiency: This series of fans using advanced CAD software by the multi-objective optimization design of new products developed by 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; 6, easy installation, covering less than the centrifugal fan, direct pipe connection or wall mounting with the wind, the installation forms can be vertical or horizontal. Considerably reduced footprint.
