1.HTF-Ⅰ, HTF-Ⅱ, said pressure type fire temperature exhaust fan, leaf type with axial flow: HTF-Ⅰ (single speed) and HTF-Ⅱ (double speed) of two; HTF-Ⅲ, HTF -Ⅳ representation pressure fire temperature exhaust professionals; 2, HTF-X for silencer type fire temperature exhaust fan, the user can choose according to the actual needs of different kinds; 3, HTF-W Series rooftop fire temperature exhaust fan The user can choose according to the actual needs of flame-retardant fiberglass hood or steel hood; 4, HTF-D for low pressure type fire temperature exhaust fan; 5. Special note: GYF and HTF series fan is similar products. Products; 1.HTF type fire temperature exhaust axial fans, the basic form of axial-flow structure, the use of high-temperature exhaust fan motor rooftop, arranged a special motor cooling systems, products by the National Fire Equipment Quality Supervision and Inspection Center Press GA211-1999 "fire exhaust fan high temperature test method" test temperature at medium temperature 300 ℃ high temperature over 60 minutes of continuous operation, 100 ℃ temperature conditions under continuous operation 20 hours / times without damage, ventilation row Smoke can be dual-use. 1.2 Installation divided by Product Category: Horizontal and roof type (W type). Divided by the amount of wind pressure: atmospheric model have type Ⅰ, Ⅱ (double speed); medium-pressure (for mixed flow impeller) has Ⅲ, Ⅳ type (double speed); there is low pressure type D1, D2 type. By the governor points: single-speed, two-speed, frequency (frequency conversion motor roof exhaust fan with variable frequency controller, the implementation of frequency control, in order to adapt to different conditions exhaust fan, it is recommended to adjust the frequency locked in 25Hz ~ 50Hz) . 1.3. In order to meet the requirements of different places noise axial flow exhaust fan fire, fans can be equipped with different lengths muffler, can also be made sheathed (housing silencer). 2, HTF-type fire temperature exhaust axial fans working conditions Operating temperature: -20 ℃ ~ + 60 ℃ (continuous operation); temperature: 100 ℃ (20 hours of continuous operation), 300 ℃ (60 minutes of continuous operation ); temperature: <90%; medium conditions: air (dust content of no more than 100mg / m3); Power supply: three-phase, 380V / 50Hz; 3, HTF-type fire temperature exhaust fan axial fan applications can be widely used rise construction, oven, underground garage, tunnels and other places smoke ventilation.
