Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Natural ventilation is the roof FRP centrifugal fan, by the indoor and outdoor thermal pressure, complemented by natural wind, without the need for power-driven situation continuously indoor air is exhausted to the outside air based on thermodynamic principles, while the inflow of fresh outdoor air FRP centrifugal fan prices, thereby promoting and improving the indoor temperature and humidity conditions. Since this is a way of saving ventilation, so the "heating, ventilation and air conditioning design specifications" GB50019-2003 the provisions of article 5.2.1: eliminating waste heat buildings, I wet the ventilation design, priority should be the use of natural ventilation. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power ventilation product characteristics at zero cost to run 24 hours without personnel FRP centrifugal fan, light weight, environmental protection, no noise, long life, easy installation and fast, wide applicability corrosion FRP centrifugal fan, unique round appearance (Taiji principles to solve the horizontal pushing) and the support structure, in order to ensure the turbine can withstand typhoon. Uses a unique variable angular diameter, as long as the pressure plate from 0 to light a variety of industrial plants steel roof angle, can be directly installed concrete roof slopes plus other accessories can also be installed.
