The fan uses a special compartment temperature measures can be built circulating impeller motor exhaust fan forced cooling principle, 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 ℃ 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. Two-speed fan control theory and start debugging Fan Related Products: The fiberglass roof fan, induced fan, centrifugal fan, induced fan, FRP fan, explosion-proof fans and other fans of the start-up and commissioning a fan to normal operation speed, should be tested for the fan of each phase input power supply is normal, the fan operating current not exceed the rated current, if the operating current exceeds the rated current price exhaust fan, the fan should check the supply voltage is normal. Use; 1.MHL3-2A, MPYH-14A (MHTFL-14A) Francis two-speed high-temperature exhaust fan for tunnels, underground garage, metallurgy and other high-temperature exhaust, in the case of fire exhaust fan buy, can quickly exhaust smoke cooling, fire into the disaster area to assist firefighters, fire safety is an essential facility. 2, the type of gas transportation: air and other non-natural, harmless, non-corrosive gases for just, in special circumstances, the choice of explosion-proof Francis fan. 3, impurity gases inside: adhesive materials are allowed within the gas contained in the dust and hard particles is not greater than 150mg / m3. 4, the temperature of the gas: MHL3-2A, MPYH-14A (MHTFL exhaust fan maintenance, Chen Yu-conditioned (certified), exhaust fan by Wu Cheng Chen-yu air-conditioning Co. wucheng Chenyu Air Conditioning Equipment Co., Ltd ..
