Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Manufacturers introduced T35-11 axial fan T35-11 axial fan is the fan industry based on energy requirements, instead of 03-11 series axial fan. With energy-saving, low power consumption without power roof fan, compact structure, smooth operation, vibration is small. T35-11 series axial fans, there are major components of the impeller, casing, collector and motors and other components without power fiberglass roof fan, simple structure, low noise, high efficiency. Purpose: This series of fans are generally applicable to transport non-flammable non-corrosive gases no significant dust, ambient temperature must not exceed 60 ℃, widely used in factories, warehouses, offices, residential heating ventilation or strong heat. This series of products, according to the impeller diameter can be divided into 10 different models, in order of priority 2.5 #, 3 #, 3.5 #, 4 # 5 # 6 # 7 # 8, # 9, # 10 and so on. Each machine can be installed into a number of blades 15 °, 20 °, 25 °, 30 °, 35 ° angle other five. This series of products are used impeller mounted directly on the motor shaft directly linked structure. Round House impeller speed does not exceed 60m / s condition is equipped with three kinds of speed: 2900,1450,960r / min. Seen in the direction facing the air inlet to the impeller to rotate counterclockwise. BFT35-11 FRP corrosion proof axial fan for the Class B T4 group Ⅱ class and below contain explosive gas mixtures dangerous places Zone 1 and Zone 2, petroleum, chemical, docks, food, pharmaceutical, military, and other factories and enterprises. As factories, warehouses ventilation, air circulation, and update the laboratory. This product is anti-acid, alkali, salt, ammonia, chlorine, non-powered turbine corrosion, waterproof, dustproof, corrosion grade F2. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Seven needs no power ventilators made: 1, no power roof ventilators and entries should be based on aerodynamics, made a streamlined, the fan inlet / outlet flow smoothly without power fan FRP, reducing pressure loss. 2, glass fiber reinforced plastic material formulations, to be performed in accordance with the relevant requirements of the plasticizer, add the appropriate amount of anti-aging and prolong life. 3, roof fan must have a reliable measures to prevent rain, snow penetration without power ventilators. 4, no power ventilation enclosure should be able to withstand the devastating impact of the local outdoor maximum wind speed. 5, should be set at the bottom of the security fence. Security fence is safe, reliable, and can effectively prevent decrease in order to avoid an accident to equipment or parts. 6, roof fan should be provided with an efficient network, all stainless steel, mesh 30 x 30 mm. 7, no power ventilation should be static and dynamic balance test before delivery, after passing the factory before. In the static, dynamic balance, the fan impeller operation allows RMS vibration velocity is less than or equal to 6.3 mm / s, and shall comply with JB / T 9101 -. 1999 "fan rotor balance" principle of non-powered ventilation fan _ Flextronics (certified) _ Tianjin without power fan ventilation equipment from Liaocheng Flextronics Limited.
