Industrial or mechanical fans come in many different shapes and sizes to fulfill all industry needs. They can be bought fully assembled, or ordered and tailor made to suit specific needs.
Here we defined some types of industrial fans used Ventilation for factories (it is also known as “การระบายอากาศสำหรับโรงงาน“ in the Thai language) and for control cabinets.

Axial Fans
Axial fans are generally used where the main requirement is a heavy air flow. The fans use axial forces to function. This allows for movement of air or gas that turns the central hub with blades that expand towards the outer edge.
There are various types of the axial fan available on the market, each of which are suitable for certain settings and industries.
Cooling Fans
Cooling fans are used in applications such as radiators, air-cooled heat exchangers, air-cooled steam condensers, wet mechanical cooling towers, and similar. These devices typically feature larger diameters for low pressures and large volumes of airflow.
Centrifugal Fans
This kind of fan uses rotating impellers to increase pressure that in turn moves air or other gases. It’s a robust, quiet and reliable piece of equipment.
Before investing in any industrial fans, consult industry experts, and be prepared to answer questions about your requirements, the setting in which the machinery will be used, and health and safety.
