1. Purpose: DTF series fire temperature exhaust fan, for a variety of building high-rise buildings, drying room, underground garage, subways, tunnels and other fire sent smoke and exhaust ventilation, low speed for two-speed fan usually through ventilation, high speed When the fire smoke. 2, features: axial flow impeller wheel, pneumatic blade, the noise is lower than the existing fire fans 8-10dB; totally enclosed motor built positive pressure blower picture, a specialized motor cooling system; the main air duct at 280 ℃ It can run for 30 minutes or more positive pressure blower, 150 ℃ when the long-term continuous operation. Efficient and reasonable, space and air volume centrifugal fan with two-thirds less. The company specializes in producing damper fire control valve exhaust valve exhaust dampers axial fan Francis fan oblique flow fan fire temperature exhaust fan wind chassis positive pressure blower pressure multi-leaf blower outlet pressure outlet pressure delivery outlet Fire Equipment leafy exhaust port plate discharges new air unit new wind ventilators air conditioning accessories and other products air conditioning fire products, the "national fixed fire extinguishing and fire-resistant components of Quality Supervision, Inspection and Testing Center," Detection of qualified, can China Fire Network product line in. HTF (A) series fire temperature exhaust axial fan Overview, Features 1. HTF (A) series fire temperature exhaust axial fan, 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) series 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 approval. 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, Fujian, Jiangxi, Yunnan , Shenzhen and other provinces (municipalities) and autonomous regions. 3. Exhaust fan high temperature performance: Fan tested in accordance with the Fire Code standards GBJ45-82 fan positive pressure blower unique design selection, high temperature motors built, configured motor cooling system can operate continuously under high temperature 300 ℃ more than 100 minutes at 100 ℃ temperature conditions for 20 hours / time is not damaged, widely used in high buildings, oven, underground garage, tunnels and other occasions; 4. Wide range of applications: according to the different requirements of senior civil use of variable speed or multi-speed drive form, in order to achieve one machine (ie, when used through ventilation and fire high-temperature exhaust) purposes; airfoil axial flow into (HTF (A) -Ⅰ, Ⅱ) and Francis HTF (A) -IG, also making rooftop silencer type. Positive pressure blower picture, I chose Hefei blower manufacturers! Huoqiu positive pressure blower is provided by Shandong Air Conditioning Equipment Co. GREAT fan.
