Product advantages: This series of fans has the characteristics of high strength, resistance to aging, good corrosion resistance, low noise, and stable operation. It is an ideal general-purpose anti-corrosion fan.
Applicable occasions: Widely used in chemical, electroplating, oxidation, power plants, laboratories, circuit boards, environmental protection equipment and other places containing corrosive gases.
  • Product Details
  • Stainless steel 4-72A\D centrifugal fan

    Stainless steel 4-72A\D centrifugal fan can transport air, non spontaneous gas, harmless gas. and non-corrosive gas Gas does not allow the sticky materian theconcentration of containing dust and nard particles isnot larger than 150mg!m3 The gas temperatureshould not exceed 80℃. The fan is widely used inthe ventilation of industrial and mining enterprises, large bulldings. hotels and other indoor places.
    Product type: The company has NO1, 2.5, 2.8, 3.2, 3.6, 4, 4.5, 5, 5.6, 6, 7.1. It can be made into two types: right-handed and left-handed. The impeller rotates clockwise and is called a right-handed fan. Expressed as "right", the impeller rotates counterclockwise, called the left-handed fan, and is represented by "left". The exit position of the fan is expressed by the air outlet angle of the casing. 4-72(No)2-7.1 is made in various types at the factory, and can be installed to the required position according to the requirements of the unit of use. That is, the position of the air outlet is adjusted from 0° to 225°, and the interval is 22.5° or 45°. There are six types (0°, 45°, 90°, 135°, 180°, 225°). The fan is driven in the A mode. Structural features: The fan is mainly composed of an impeller, a casing, an air inlet, a motor plate and the like with a direct-connected motor. Impeller: consists of 10 rear-tilted airfoil blades, curved front discs and flat rear discs. After dynamic balance correction and aerodynamic performance, it has the characteristics of balanced operation, small vibration, high efficiency and long service life. Housing: welded with a steel plate into a volute casing. Air inlet: made into a whole (all mold molding), installed on the side of the fan, the axially parallel wear surface has no curved shape, which enables the gas to smoothly enter the impeller with less loss.
