AC exhaust fans are mainly used in industrial manufacturing processes where cooling, ventilation and air change are required. They have heavy-duty characteristics and can be driven by AC power to provide high exhaust efficiency to meet factory demands for exhaust quality. AC exhaust fans are designed to help solve problems such as heat, fumes and odours generated by machines or processes.

The internal structure of an AC exhaust fan consists mainly of a stator and a rotor. The stator includes the motor, outer frame, bearings, grommets, springs, silicon steel sheets, etc. These components serve to provide stable support and rotational power to the fan. The rotor includes the fan blades and shaft, and the design and material selection of the fan blades affects the exhaust efficiency and noise level.

AC exhaust fans work on the principle that they are driven by an alternating current (AC), with two sets of coils working alternately to produce different magnetic fields, which in turn drive the fan blades to rotate. A starter capacitor is also an important part of an AC exhaust fan, which usually has 250V between 12uf to help the motor start quickly.

The advantages of AC exhaust fans are that they can be driven by alternating current, provide high exhaust efficiency, and can withstand harsh environments for locations that require cooling, ventilation, and air change. Their design and material choices can help reduce noise levels, increase exhaust efficiency, and can be adjusted as needed to meet different exhaust needs.

The disadvantages of AC exhaust fans are that they require a power source and circuit control, and they require regular maintenance and cleaning to ensure proper operation and exhaust efficiency. In addition, AC exhaust fans are relatively expensive and may not be suitable for some small factories or homes.
