Quality not to be missed | Products Factory】 【roof fan | Jinzhong roof fan is provided by Horizon Air conditioning equipment. We are a Texas Air Conditioning Equipment Co., Ltd. Hongxin (www.hxktsb.com) located at: Shandong Dezhou specializes in: New air unit fresh air ventilator fan air pressure delivery outlet damper chassis outlet DW-87-8 type.. FRP roof fan with low noise and vibration. Shell using the latest thermal spraying anti-corrosion treatment, anti-corrosive atmospheric moisture roof fan products factory, to ensure stable operation of the fan in the room outside conditions. Suitable for forced air power, petroleum, chemical, metallurgy, warehouses and other modern architectural design. Fan mounted vertically on the roof, there are mushroom-shaped hood room sleet. Binder comes to automatically open the throttle, the fan stops running when the throttle is closed, in order to reduce indoor heat loss season Division, loose-leaf dampers for the fan attachment, selection by the user when ordering. Mushroom-shaped hood and chassis are made of fiberglass. Detachable hood and chassis separately, easy installation and maintenance. Direct the impeller on the motor, using a fiberglass wing-shaped blades, so fans have a good aerodynamic performance fan running while working medium industrial atmosphere, when equipped with ordinary motor medium temperature ≤ 40 ℃ (equipped with explosion-proof motors, medium ≤ temperature of 55 ℃). When the medium temperature is 25 ℃, relative humidity less than 95%, the amount of dust medium (containing solid impurities) should not exceed 100 mg / cubic meter. If the fan above those provisions, to be presented at the time of ordering for special designs. Fan performance provided by the factory, are to air performance at standard conditions (temperature is 20 ℃, 50% relative humidity, atmospheric pressure 101325Pa (760 mm Hg) than raw gas 1.2 kg / cubic meter) when. If the fan roof fan when the price of work in non-standard conditions, the performance will have translated through the appropriate formula. Roof fan which of these categories: From the material can be divided into ordinary steel, glass, steel roof fan manufacturers, aluminum material. Although a wide range, but according to its usefulness, glass steel roof fan no matter from exhaust ventilation effect, as well as power consumption has an absolute advantage, and glass and steel roof fan sound is very low, it will not affect the surrounding environment, any negative impact to the workers roof fan, but, fiberglass with anti-acid, anti-corrosion and other characteristics, which compared with the same fans, which greatly increased life expectancy, thus, also a glass and steel roof fan energy saving roof fan.
