 4-72 centrifugal fan, F4-72 anticorrosive centrifugal fan, B4-proof centrifugal fan 4-72 centrifugal fan is an energy efficient centrifugal fan, its airfoil blades, curved front plate and cone curved impeller Imported rapids and other structures fan, the fan has excellent aerodynamic performance, enduring career in China's economic construction, 4-72 centrifugal fan in the country is the use of the first fans, but also the most common use of fans, from high-rise buildings to the Underground Railroad, a blast from the boiler to the plant ventilation, 4-72 fan everywhere. 4-72 centrifugal fan in the model number, meet the requirements of different occasions, No2 ~ 6A fan mainly by the impeller, housing, the air and motor components. No8 ~ 10C, D fan as well as group and pulley or drive coupling. 4-72 centrifugal fan rotation direction of divided right rotation and left rotation, face a period of mixed flow fan from the motor, the impeller rotates clockwise, rotate the right to become fans, to the "right" means. Counterclockwise rotation, left rotation fan becomes to "left". Direction of rotation of the fan must be marked at the time of ordering. B4-72 explosion-proof centrifugal fan centrifugal fan centrifugal fan is 4-72 derived products, special occasion is proof blower fan products prices, with explosion-proof motor, the key components of the surface coating to prevent static electricity or the use of non-ferrous metal manufacturing fire smoke fan, can effectively prevent static electricity spark friction leak and electrical components. Proof centrifugal fan for transportation of flammable, explosive gases fan for general purposes. Its transport medium maximum temperature does not exceed 80 ℃, the amount of dust and other solid content of impurities is not greater than 100mg / m3, a diameter of not more than 1mm. B4-72 explosion-proof centrifugal fan is dedicated fan, standing applied to fuel gas boiler room, workshop high concentrations of dust, oil depots, gas stations, warehouses, and other flammable items stored with explosion-proof requirements of the occasion, can transport flammable, the volatile nature of the gas explosion and easy.
