Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Axial fan wheel spinning reel traditionally backward axial fan wheel plant processes are generally carried out using three roll rolling without power ventilators how to install, and then welding rough shape, then the mechanical finishing, as this species backward process leading to the hub dimensional tolerances and geometric tolerances can not be effectively guaranteed, and the impact of stress and deformation due to welding, but also lead to reduced accuracy of the fan, the fan affects the efficiency of the use of Zhejiang some Blower Drawing mold manufacturing hub, but only a very few product model, because a larger die size wheels, costly, and the need for supporting the thousands of tonnage pressure machine in order to be implemented, and the manufacturing cost of spinning tires with only drawing mold around 1/20, or even less, and the spinning tire tool machining cycle than drawing die even shorter for the fans varieties, small batch of product characteristics is extremely appropriate. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power ventilation roof ventilation various properties: 1, zero failure: a strict ball shape of the structure, the upper and lower permanently lubricated ball bearings ensure long life, no maintenance, no need to replace parts without power fan works, the United States UBC closed high-precision bearing systems provide absolute quality assurance. 2, rugged. Can be bent and rolled leaf design with one piece, is the most robust turbine ventilators. 3, anti-corrosion: Use stainless steel, acid resistant, resistant to seal, but also corrosion resistant non-powered fan, the material using the best materials ventilation equipment. 4, rain properties: designed to be absolutely rainproof, it has the turbine blade, while the blade is rotated by centrifugal force, the indoor air is discharged to block the entry of rain, while between the blades and the blade due to rapid rotation, is formed each piece to fill the gap, even when attached to a small raindrops on the blade, the blade can flow along the roof. Therefore, the turbine meter waterproof ventilation is the best five, running equipment: The United States closed UBC high-precision bearing systems, highly heat-resistant synthetic bearing grease is the best lubricant permanently self-lubricating, no maintenance Even if the wind speed is less than 2 km in the breeze, but also to self-running. 6, to prevent noise: the use of wind-driven principle, not the use of motor power, cost-free electricity-free operation, the turbine ventilators stop self rotation, so silent no noise when running. 7, anti-dust. Turbine ventilation is rotated 24 hours non-stop, easy to attach stainless steel dust without power fan, do not need cleaning. 8, light weight: light weight turbine ventilators, very light and strong, in the design and planning of the plant structure, the roof does not need to worry about heavy load. 9, mining light. There is a gap between the blade and the blade, the light will thus enter the room, increase the illumination. No power fan installation, Gansu no power ventilators, ventilation by Flextronics Flextronics Liaocheng ventilation equipment Limited. Liaocheng Flextronics Ventilation Equipment Co.
