Two-speed fan at the top health nuisance exhaust system made use together is well known, type a lot of smoke and heat fire, and consume large amounts of air. On its harmful effects, particularly at night to smoke, smoke in his mouth many types of toxic factor, even if the non-toxic, also may be due to burning to make hypoxia suffocating to death. Back to produce fire every thing, who burned to death, most are also the first to be burned to death after a faint smoke, smoke when fire spread faster rate, the extent of up to 0.5-0.8m / s, straight to reach 6-8m / s. In the fire, one that is fire, then a nuisance, smoke. Is off the fire extinguishing, broken smoke source, harm, exhaust system supply was safe escape route, two-speed exhaust fan, and a favorable start the fire. The fan uses a special compartment temperature measures, Binzhou exhaust fan, the impeller can be built on the motor cycle forced cooling, 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, 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), the noise 2. Low 8-10dB (A) 6% lower power than the existing Fire fans ; main air duct medium temperature of 280 ℃ continuous operation when more than 30 minutes, roof exhaust fans, 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. 1. Commissioning number less than two, one to control power, one observes fan operation, abnormal phenomenon immediately stop inspection; First check the direction of rotation is correct; fan during each phase of the operation should be checked whether the current balance, current is exceed the rated current; if not normal, you should stop checking. After running for five minutes, the fan down to check whether there is abnormal phenomenon, confirmed that no anomalies start running again. 2. A two-speed fan test, fire exhaust fan, you should start low, and check the direction of rotation is correct; it must be starting after the high-speed fan still renewed, to prevent reverse rotation speed, causing the switch trips and motor damage.
