Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Roof ventilation is divided into several main components are a few: Turbine Head: The head of wavy blade circular turbine design. Axis: high quality stainless steel bottom bracket bearings: a fully enclosed ubc bearings, lubrication-free, long life. Bracket: made of imported steel bars. Variable angle tube neck: You can change depending on the roof slope angle of the neck, to stay in the rotation, greatly improving efficiency. Bottom: a metal forming waterproof substrate products are used axial fan 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, corrosion roof turbine ventilators, 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 machine tools to produce heat and smoke pollution within the plant, 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 density of hot air cooler air will be small , that is lighter than cold air hot air turbine ventilators, therefore, indoor hot air to rise turbine ventilation manufacturers, cold air to drop, heat or indoor smoke pollution will gather near the roof, so the indoor temperature is high, the pressure great. Then as long as the rotation of the turbine on the roof with no power fan, indoor heat or smoke pollution will be void by the blades to spin works out outdoor diversion method, when the heat is withdrawn without power ventilators interior will produce low pressure, The outdoor air is lower than the high pressure, the air flows into the indoor ventilation turbine prices, fill the space heat is extracted, and then to adjust the temperature, to the decontamination of smoke effects, clean indoor air becomes cool. 500 turbo ventilators | Flextronics ventilators (certified) | sunshine turbine ventilation ventilation equipment from Liaocheng Flextronics Limited.
