Products; 1.HTF type fire temperature exhaust axial fans, the basic form of an axial flow type structure, with high temperature motor, arranged a special motor cooling system exhaust fan buy products by the National Fire Equipment Quality Supervision and Inspection Center Press GA211-1999 "fire exhaust fan high temperature test method" high-temperature test at medium temperature conditions of high temperature 300 ℃ continuous operation over 60 minutes at 100 ℃ under the conditions of continuous operation 20 hours / times without damage, smoke ventilation can be dual-use. 1.2 Categories by Mounting points: horizontal and Roof (W type). Press the air flow pressure point: there is pressure type Ⅰ and Ⅱ (double speed); medium-pressure (mixed flow impeller) has Ⅲ, Ⅳ type (double speed); there is low pressure type D1, D2 type. Press Speed ??points: single-speed, two-speed, variable frequency (by frequency conversion motor with variable frequency controller, inverter implementation exhaust fan, to adapt to different conditions, it is recommended to adjust the frequency locked in 25Hz ~ 50Hz). 1.3. To meet the noise requirements of different places, the fan can be equipped with different lengths muffler, it can be made into a sheathed (housing silencer). 2, HTF-type fire temperature exhaust axial fans working conditions Operating temperature: -20 ℃ ~ + 60 ℃ (continuous operation); temperature: 100 ℃ (continuous operation 20 hours), 300 ℃ (continuous operation 60 minutes ); 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 fans can be widely used application rise construction, oven, underground garage, tunnels and other places exhaust ventilation. The fan uses a special compartment temperature measures built cycle impeller can forcibly cool the motor, ensure that the motor temperature does not exceed a predetermined value. Run at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Can play a role of ventilation and fire smoke. The product was identified as Shandong Provincial Fire Department fire products sentinel production. YTPY type, fire temperature exhaust fan with high efficiency, smooth operation exhaust fan size, low noise, high-temperature structure is reasonable, easy to install, can be vertical, horizontal and hanging installation. The fan is designed with special air-cooled motor cooling system built-in motor type; the use of advanced aerodynamic design of the blade (swept forward, forward) wucheng exhaust fan, so noise than existing fire fans 2, low 8-10dB (A ) low power 6%; the main air duct medium temperature of 280 ℃ when more than 30 minutes of continuous operation, 150 ℃ when the long-term continuous operation. Product Attributes This fan uses a special compartment temperature measures built cycle impeller can forcibly cool the motor, ensure that the motor temperature does not exceed a predetermined value. Run at 400 ℃ 100 minutes or more, long-term operation at 100 ℃. Ventilation and fire smoke can play a role in the product altogether divided into: ① ② atmospheric pressure single-speed two-speed single-speed ④ ③ MV MV dual-speed four series. HTF series of high-temperature exhaust fan fire Overview: HTF series fire temperature exhaust fan with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation. HTF series fire temperature exhaust fan of "national fixed fire extinguishing systems and fire-resistant component quality inspection center" test qualified, the performance of the leading domestic level. High temperature performance: Fan Test conform GBJ45-82 Fire Code standards, established above the standards of corporate internal control assurance system to run more than 60 minutes continuously under high temperature 300 ℃ conditions, at a temperature of 100 ℃ for 20 hours / time does not damage, widely used in senior civil oven, underground garage, tunnels and other occasions.
