Axial fan products are used impeller mounted directly to 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 of the impeller inlet face counterclockwise rotation. BFT35-11 FRP corrosion proof axial fan for class B T4 group and Ⅱ class and below contain explosive gas mixtures Zone 1 and 2 hazardous location area, petroleum, chemical, port, 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 ion corrosion, waterproof, dustproof, corrosion grade F2. No power ventilation system on the roof of the plant, can achieve very good ventilation effect. Because often due to the operation of the machine tool to produce heat and smoke pollution in the factory, according to the "thermal expansion and contraction," the principle of hot air expands, so the number of molecules in a given volume of air is reduced, relative geothermal air density will be smaller than the cold air , that hot air lighter than cold air, so the indoor hot air to rise, cool air to fall, the indoor heat or smoke pollution can accumulate in the vicinity of the roof, ventilation, so the room temperature high pressure. Then as long as the rotation of the turbine on the roof with no power fan, heat or indoor smoke pollution will be by the blade clearance for diversion method works spin out outdoors, when the heat extraction, window ventilation, no power ventilation indoor will produce low pressure, while the outdoor air lower than the high pressure, the air flows into the interior, filling the extracted heat space, and then to adjust the temperature, to the decontamination of smoke effects, indoor air becomes clean and cool. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Corrosion fan preservative fan trends generally moving in a direction of how to develop it, consider the following article. 1. The use of variable pitch axial fans instead of large-scale anti-corrosion centrifugal fan anti-corrosion; 2. further improve aerodynamic efficiency corrosion fan, the device efficiency and the use of efficient ventilation design to reduce power consumption; 3. Improve smoke, exhaust Dust fan impeller and casing wear; 4. Reduce corrosion fan noise; 5. Implement variable speed adjustment and automatic adjustment. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. No power ventilation utilizes natural convection of air principle, power ventilation, becomes in any direction parallel to the flow rate, and the vertical air flow conversion. With the use of the chimney effect itself, buildings and equipment to achieve an internal and external ventilation equipment. No power ventilation applications: large factories, warehouses, stadiums, pet farm functional areas, high-rise buildings, residential and other ventilation. Power ventilation, Flextronics ventilators (certified), ventilation consists Liaocheng Flextronics ventilation equipment provided. Liaocheng Flextronics ventilation equipment (www.lcwctf.com) (www.lcwctf.com) is an industry leader in Shandong Liaocheng, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Flextronics ventilation in leadership with the staff warmly welcome all inquiries negotiations to create Flextronics ventilation a better future.
