Liaocheng Huarui Ventilation Equipment Co., Ltd. is a professional company that produces ventilation skylights, ventilation buildings, unpowered ventilators, unpowered wind balloons, hoods, centrifugal fans, negative pressure fans, roof glass fiber reinforced plastic fans, and axial flow fans. Phone: 0635-8380192
Ventilation skylights and ventilating caps have the characteristics of light weight, beautiful appearance, high ventilation efficiency, good rain and snow resistance, windproof performance, and easy installation. The unpowered fan is to use the natural wind speed of nature to promote the turbine's turbine rotation, and use the principle of indoor and outdoor air convection to accelerate and convert any parallel air flow into vertical air flow from bottom to top to improve indoor ventilation. A device for air effect. The fan does not use electricity, has no noise, and can run for a long time. According to the natural law of air and the principle of air flow, it is rationally arranged on the top of the roof, which can quickly exhaust the hot and dirty gases in the room and improve the indoor environment. The centrifugal fan is a machine that relies on the input mechanical energy to increase the pressure of the gas and discharge the gas. It is a driven fluid machine. Centrifugal fans are widely used in ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and cooling of air conditioning equipment and household appliances Ventilation; drying and sending of grain; wind tunnel wind source and inflation and propulsion of hovercraft. Negative pressure fan is a cooling principle using air convection and negative pressure ventilation. It is a kind of opposite from the installation site-the door or window naturally inhales fresh air, and the sweltering indoor air is quickly forced out of the room. Any poor ventilation problems are Improved machine, cooling and ventilation effect can reach 90% -97%. FRP roof fan is an advanced roof exhaust equipment at home and abroad. It is mainly used for ventilation of hotels, restaurants, theaters, office buildings, laboratories, factories, houses and other buildings. This series of fans have the characteristics of beautiful appearance, compact structure, high strength, light weight, corrosion resistance, aging resistance, low power consumption, low noise, reliable operation, convenient installation and maintenance, etc. Improve efficiency by 30%. According to user needs, explosion-proof roof fans can also be produced, whose performance is the same as the same number.
