First of all, what working conditions will use the axial fan, simply put, the axial fan and the general household fan working principle is the same, the gas along the axial flow of the ventilation fan is called the axial fan. The difference between a domestic fan and an axial fan lies in the air pressure of the fan, and axial fans are generally used under conditions where the air pressure is below 490 Pa.

The composition of the axial fan structure.

An axial flow fan is mainly composed of a wind collector, impeller, front deflector, rear deflector, diffuser cylinder, and motor.

Second, the material of the axial fan.

Different use conditions demand will certainly choose a different material. Different materials, the cost of products made out of different. Fans are made of carbon steel, stainless steel, glass steel, aluminum alloy, high strength steel. Different materials lead to different costs for axial flow fans. Today I will mainly explain the category of carbon steel material, axial flow fan in the use of carbon in steel material mainly involved the components of the wind collector, impeller, before the deflector, after the deflector, diffusion cylinder, and 5 major components. These five components have a one-piece and split type two kinds, one-piece material cost is low, but the processing complexity is high, and the cost is higher than the split-type processing; split-type material cost is high because it involves the link at the material increase, but the processing difficulty is weak, so the processing cost is lower than the one-piece. The overall cost difference between the one-piece and the split type is not too great, as the assembly cost of the split type is slightly higher than that of the one-piece type. So basically the difference in construction cost is not significant. Another issue is the choice of carbon steel material, positive material, secondary material, cold plate, hot plate, or different materials, the price will have an up and down range.

Third, according to the working conditions of the motor used.

At present, I understand the axial flow fan use working condition is generally divided into general ventilation and ventilation ordinary motor; high temperature resistant working condition motor; with moisture working condition moisture-proof motor; flammable and explosive working condition explosion-proof motor.

Fourth, the main components of the axial flow fan airfoil.

There are many fan manufacturers, the core technology lies in the airfoil, the airfoil is also known as the moving leaf, the size of the airfoil, twist curvature, the thickness of the plate, and the size of the hub size, etc. in the fan structure plays a decisive role. The area of the airfoil determines the size of the air volume, and the speed of rotation determines the air pressure of the fan. The higher the precision of the components of the axial fan, the lower the flow losses and the higher the efficiency.

Combined with the four points explained above, this configuration determines the cost of the axial fan. The material of the housing, the type of impeller, and the power of the motor determine the sales price of the axial fan. So when choosing a fan manufacturer, you need to clearly understand the manufacturer's production capacity and processing capability as well as design and inspection strength. However, we can not look at the price of the fan alone, even if the same type of product, different manufacturers, processing, and inspection methods are different, the cost will be relatively different. Industrial products sold are the use of the effect, not the price, the demand is far more important than the price. It depends on your needs to determine the price of the product!
