Jianhua fiberglass roof fan roof fan Chongqing

F4-72 FRP centrifugal fan body is made of glass fiber reinforced polyester, it has a good air performance, light weight, high strength, corrosion resistance, not aging, low noise, and wide range of advantages apply to the carriage of certain concentration of corrosion gas, metal parts are all covered; various parts of the fan to prevent erosion, building ventilation, general carriage of the gas temperature is below 50 degrees Celsius. Optional high temperature (120 degrees Celsius) temperature type FRP centrifugal fan and explosion-proof fans. * Good quality and good service * expect to visit. Roof fan must have reliable in rain, snow and wind and sand basic performance, but now a lot of roof fans are designed with only rain function, ignoring the snow and sand will not only from the top into the fan at the outdoor wind speed reaches a certain intensity of the situation, also may enter the fan from the bottom. Some uses for internal activities louver roof fan air backstop device seems to prevent snow falling in the room, in fact, the snow accumulation on the activities of blinds, room temperature after thawing can cause dripping phenomenon, can not play a role in anti-snow . ... The wind turbine housing cap retail format * good quality * low expectations coming; there are three types of fan A, Axial roof fan: Model DWT-I type, suitable for low pressure, high flow usage scenarios . According to user needs can also be designed to send two-way reversible exhaust, which has positive and negative features of working conditions equivalent fan, DWT-Ⅴ type such as; B, centrifugal roof fan: Model DWT-Ⅱ type, DWT-Ⅲ type Two versions for smaller air volume and pressure requires high; C, no motor turbine exhaust fan: Model for the DWT-Ⅳ type, is an indoor and outdoor air pressure driven by the special curved blade with the axis of rotation thereby discharging the ideal energy-saving ventilation of indoor air.
