4-72 C High Quality Big Centrifugal Fan

4-72-C Model Highlights:

 

  • Belt driven make  easily control speed.
  • Strong body with pure copper Increase the whole machine life.
  • Multi-functional in many area.
  • The air inlets of the fan is also made with fixed structure, located at the side of the fan, curve shape with the section of axial parallel, to ensure that air can be smoothly enter the impeller more efficiently.
  • This centrifugal fan can be used in ordinary for indoor ventilating, deliver air and other gas which is non-hypergolic, harmless to human and non-corrosive to metal.
  • The air which isdelivered by this product is forbidden to contain with stickum, also the dust and hard particle.

4-72-C Model Features:

 

: Material Properties


:4-72-C type boiler centrifugal fan is designed to fit the equipment of heavy industries  which can burn any kind of coal base and equipped with smoke and dust-removal device. It is applicable as long as the air volume and the performance are fit the condition. However, the highest temperature shall not exceed 130℃. Our company can provide the stainless steel heat boiler centrifugal fan when the temperature of air must exceed 130℃. It can be used on many occasions transfer materials, ventilation and improvide motivation to systems.

 

: Selection

: The  centrifugal fan has single inlet, the model No. has No6,7,8,10,12,14,16, these  kinds.
: The centrifugal fan can be made into two forms which are left-hand rotated and right-hand rotated. Face the fan from one end of the drive set. If the impeller rotates clockwise, we called it right-hand rotated, in short we use “right” for expression. If the impeller rotates anticlockwise, we called it left-hand rotated, in short we use “left” for expression. 
: The position of the air outlet of the fan is indicated by the angle of the air outlet of the housing. “left” and “right” can be made into 0°,90°,180°three kind of angles. 

 

: Fan Structure


:  The boiler centrifugal fan is made by the impeller, housing, air inlet, driven set, regulating door and other parts. 
: The impeller has 12 backward inclined plate blades of 16Mn material, which are welded in the arc cone impeller cover and in the middle of the plate-shaped disc, and are corrected by dynamic balance. Therefore, it runs smoothly, has high strength and wear resistance, and has a long service life,
