Industrial Fans & Blowers

Industrial Blowers

When discussing air blowers they typically use centrifugal force to propel air ahead. If you break down a centrifugal blower, also know as a centrifugal fan, it’s a wheel housing small blades that move around the circumference. This allows the air to gain velocity in the center of the wheel and push out toward the edge.

How Do Exhaust Fans & Blowers work?

R. Williamson & Associates and its partners have the knowledge and application experience with air moving applications to provide you with innovative, efficient and effective solutions for any of your air handling needs. Categorized by their airflow characteristics, the predominate categories for commercial and industrial fans & blowers are centrifugal and axial flow. Centrifugal fans direct the air at right angles to the airstream as it enters the inlet of the fan and is suited for handling materials in the airstream.  Axial fans move the air along the same axis as the airflow out the outlet of the fan and are applied when moving clean air.

Take a look at what our fans & blowers can do in your building below:

  • General or Process Ventilation
  • Heat Removal
  • General Circulation
  • Conveyance of Air, Gas, Dust, Fumes, Heat, Cooling, Material & More

Types of Blowers

Industrial Blowers are different from axial fans due to the way they move air. Centrifugal blowers are like industrial blowers because they have 1 of 7 types of wheels or blades that take in the air into the inlet of the blower housing section.

This is different from an axial fan or industrial axial fan because they use a propeller to bring in the air into its housing section.

With an industrial or centrifugal blower the air is sucked in through a wheel. It’s then dispersed at a 90 degree angle through the discharge encasement.

Axial fans release air in the same axial direction, that is, at 90 degrees through the encasement. To put it simply, fans move air with the use of propellers. Blowers move air using a wheel type design.

Blowers typically call under the umbrella of industrial cooling fans, industrial exhaust fans, industrial fan blowers, industrial ventilation fans, and most commonly referred to as industrial fans. However, whatever a person calls them they are essentially the same. The most important factor one must consider when talking about an industrial fan is what type of application it will be used for.

The aforementioned list of industrial fans typically fall under the 2 main categories: Centrifugal or Axial.
Although the word industrial in regard to fan is used quite loosely, it’s meant to portray that the construction or build of the fan is made of more durable parts. 

This is to allow the industrial fan to be used in heavy duty industrial operations. That is why industrial fans use larger shafts, thicker material, better quality bearings that can stand the test of time. Perhaps most importantly, industrial fans use corrosion resistant materials that can withstand high temperatures compared to your typical commercial heating, venting and air conditioning (HVAC) fans.
