(1) HTF (GYF) series fire temperature exhaust axial fans, with excellent performance exhaust fan wucheng, good high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation. (2) HTF (GYF) series axial fan the fire temperature exhaust fan sold in Beijing, Tianjin, Shanghai classics, Chongqing, Zhejiang, Guangdong, Jiangsu, Shandong, Henan, Hebei, Anhui, Hunan, Sichuan, Liaoning, Hubei, Shaanxi , Jilin, Inner Mongolia, Shanxi, Guizhou, Heilongjiang, Fujian, 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 that can run more than 100 minutes in the 300's exhaust continuous intake of high temperatures fan, 100-degree camera's continuous 20 hours at a temperature condition / not damaged, are widely used in senior civil factory exhaust fan, oven, underground garage, tunnels and other occasions; HTF series exhaust fan fire for high-rise buildings, underground construction and tunnels, drying room and other high-temperature exhaust or ventilation. Continuous operation at 280 ℃ under the high temperature for 30 minutes or more, the medium temperature at 100 ℃ continuous operation 20 hours / times without damage, fire is the ideal necessary facilities. 1, the performance of the fan performance table lists the properties in the most efficient range, according to the performance of the air volume is divided into five working points, according to prevail in the selection of the performance table. Qualified fan factory is rated flow, total pressure error does not exceed ± 5%, the performance of the selection list is performance under standard conditions, regardless of the technical documentation or performance are subject to the requirements of the standard state orders; 2, the fan installation can be divided into horizontal and roof type, air volume, total pressure, dimensions and other properties have special requirements; set smoke damper in exhaust fan and exhaust pipe connections, set in the exhaust pipe is not the end row smoke valves, exhaust valves and pay attention to the function smoke damper is completely different devices. Exhaust valve usually normally closed, opened fire, and alarm host linkage, open the condition that an outbreak of fire alarm system (detector alarm), fire alarm host into automatic mode, exhaust valves open automatically start linkage exhaust fan. Smoke damper is usually always open exhaust fan introduction, but also turned a fire, but when the smoke temperature reaches 280 ℃, the exhaust damper automatically closes, the linkage has been opened fan stops running.
