There are two types of industrial fans: Axial fan and Centrifugal fan. The other fans and blowers divide in multiple classifications like Industrial Blowers, Ventilation Fans, Industrial Exhaust Fans and many others terms are used to define an Axial or a centrifugal fan.
Centrifugal fans:
- An industrial centrifugal fan ( (it is also known as “พัดลมแบบแรงเหวี่ยงอุตสาหกรรม” in the Thai language) is slightly different from axial fan.

- That blade is a circular drum or plate configuration with a knife, or ribs are attached around the circumference of the space in the center, is called the impeller.
- These fans displace air radially, changing the direction of the airflow. The airflow created by centrifugal fan is directed through a system of ducts or tubes.
- A centrifugal fans used for common ventilation, in HVAC systems, and in the dust collection. It creates a much greater air pressure, with greater efficiency then axial fans.
Axial Fans:
- An axial fan blade is mounted itself on the motor axial, a bit like a plane propeller, and pulls air through a linear knife and drives it out of the back of the fan body through what is known as the spigot or tap.
- By design, Axial fans create airflow with a high flow rate, meaning they create a large volume of airflow. However, the airflow create a low pressure. They require a low power input for operation.
- An axial fan is the type that you are likely to see, and have been installed by the builder or electricity if you ask them to adjust to your fans. They are mostly used axial fans rather than centrifugal fans.
Axial fans, when used as intended will give excellent results with minimal noise or the centrifugal fans achieve longer distance, but it will generate more noise in operation.
