"Axial Fan" blade pushing air with the shaft in the same direction flow. With the axial impeller and propeller products somewhat similar, it is at work, most of the flow of the air flow parallel to the axis, in other words in the axial direction. this fan static pressure when the inlet gas stream is 0 free air, its power capacity is relatively low, when running with the airstream will rise back-pressure power consumption will increase. "Axial Fan" is usually installed in the electrical equipment cabinets, sometimes integrated in the motor, this fan because of its compact structure, you can save a lot of space, and ease of installation, it is widely used. "Axial Fan" which is characterized by: high flow rate, moderate pressure.
