Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Should consider installing roof ventilators wind areas, roof ventilators in the typhoon-prone areas and strong winds should be used with good anti-typhoon performance roof fan, its center of gravity should be as low as possible, with streamlined structure to reduce wind resistance, anti-umbrella Wind rain-hat very unsatisfactory performance, minimize the use of the structure. The advent of strong winds is non-normal conditions, rain hat design can stop the situation into account. Roof fan in the typhoon-prone areas and strong winds may also consider using the automatic installation of the aileron, even in strong winds, weather, due to the installation of automatic aileron will reduce a lot of wind and rain to enter. Aileron will return by spring mechanism in place, while the ailerons can also serve to reduce the air resistance of the flow sheet effect, roof ventilators to achieve the effect of increasing the amount of wind. No power fan bearing temperature abnormally elevated main reasons can be attributed to improper installation, poor lubrication, cooling is not enough, bearing exception. Axial fans are promoting the use of natural natural wind speed rotation of the turbine fan, and the indoor and outdoor air convection principle, parallel to the air flow in any direction, and into a bottom vertical acceleration of the air flow, in order to improve indoor ventilation change An apparatus for gas effect. The fan no electricity, no impatient tone without power fan works, long-term operation. Based on air flow and air flow principles of natural law, is set at the top of the roof of rationalization can quickly exhaust gas indoor hot and dirty, improve the indoor environment. Axial fan impeller products are used directly mounted 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, 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 No power fan manufacturers, that hot air is lighter than cold air, so the indoor hot air to rise, cool air to fall, the indoor heat or smoke pollution will gather near the roof, so the indoor temperature high pressure. 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 hot air out of stainless steel non-powered fan, no power ventilation indoors Low pressure will produce no power ventilators, while the outdoor air is lower than the high pressure, the air flows into the room, filling the space heat is extracted, and then to adjust the temperature, to the decontamination of smoke effects, indoor air becomes clean cool. No power fan works | Zhengzhou no power ventilators | Flextronics ventilation provided by Liaocheng Wei Chong ventilation equipment. Liaocheng Flextronics Ventilation Equipment Co. (www.lcwctf.com) (www.lcwctf.com) strong, credible, Shandong Liaocheng fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Flextronics ventilators and you hand into the brilliant, for a better future!
