In this article we’ll be using the terms industrial blower, industrial blower fan, and centrifugal blower interchangeably since they are typically the same, it basically depends on the application. 

Many blower fans fall under the classification of industrial blowers, industrial fan blower, industrial fans and industrial ventilation fans. They are typically the same, but the biggest difference when using any of these terms is what the purpose of the blower or for what application it will be used for.

Centrifugal blowers are the workhorse of the HVAC industry. They are among the most versatile and efficient air ventilation equipment. They are typically quiet and dependable. Centrifugal fans are designed to work in various working environments and for different applications as you will discover below.

How do Centrifugal Fans Work?

Unlike the more common axial fan, a centrifugal fan has a bunch of small blades attached to a ring, which forms an impeller. When the assembly rotates these little blades push air away from the center, and that creates a low-pressure area in the center.

Therefore, air is drawn into the impeller parallel to the axis of rotation. Once inside the wheel it turns 90 degrees and then shoots off the wheel in a 360 degree pattern (source).

Industrial Fan Drive Systems

There are many other factors to consider when deciding which type of blower to install. However, fans have 2 main drive systems.

Direct Drive

Direct drive blowers are more cost effective and usually used in smaller blowers. Using less parts makes them easy to assemble and repair, which in turn makes them easier to maintain. 

Direct drive fans are more efficient since there is no drive loss.

Belt Drive

Typically used in larger blowers because they offer more versatility when matching airflow requirements that have a variable pitch motor and pulley system.

Some belt drive systems have variable frequency, which makes them as versatile as direct drive blowers.
