industrial blowers

Industrial blowers are devices that increase airflow in a workspace to remove potential contaminants, dust, and dirt in a workspace. They use electric motors, impellers, and air foils to create a positive air pressure range somewhere between that of a fan and a compressor. That means they offer a happy-medium option that makes them an essential component of many manufacturing and production facilities and applications. 

Below, we’ll explore more about industrial blowers, including some of the most popular types and what they’re used for — giving you the information you need to choose one that will work best for your facility. 

5 Types of Industrial Blowers

Over the years, industrial blower engineering has advanced to produce a variety of industrial blower types, all with varying designs, sizes, and applications. There are a multitude of industrial blower types on the market today, but we’ll only focus on five of the most popular — known for their efficiency and reliability — in this article. 

1. Positive Displacement Industrial Blowers

Positive displacement blowers use a safety valve to release air at a specific time, direction, velocity, and pressure. They have two propellers that counterrotate as air enters the chamber and exits the outlet pipe, maintaining consistent flow and pressure. In fact, the term “positive displacement” comes from the fact that the air is displaced from one end to another without changing any of its volume. 

Positive displacement blowers can be used for a number of applications that require constant air flow and pressure, but they’re most commonly seen in these industries:

  • Aquaculture
  • Chemical
  • Milling
  • Oil & gas
  • Plastics

2. Rotary Lobe Blowers

Rotary lobe blowers feature two or three rotating devices (known as lobes) that encourage air compression. These lobes turn within the blower’s chamber and create pockets of air that have a vacuum effect. This vacuum pressure pulls a fixed volume of air and continually forces more air into it to create higher pressure. 

Rotary lobe blowers are most often used in the following applications:

  • Wastewater treatment
  • Pneumatic conveying
  • Vacuum systems
  • Surface treatment
  • Aquaculture

3. Centrifugal Industrial Blowers

Centrifugal blowers are great at maintaining a constant transfer of gas and air, while also blocking air contaminants. They work by intaking a stream of air through a set of rotating impellers, where the speed and volume of the air is increased. Then, the fan wheel shifts and accelerates, continuously increasing the amount of air passing through and the kinetic energy within the entire system. 

Centrifugal blowers are beneficial in industries and applications that require large volumes of air and gas to flow at high pressures. You’re most likely to find them in ventilation systems, but they’re also used for the following purposes:

  • Dust collection
  • Air combustion for burners
  • Drying and cooling systems
  • Sewage aeration

4. Side Channel Blowers

Side channel blowers transport air or gas by rotating a fan with many blades through a narrow fitting pumphouse at high speeds. The pressure in the channel increases as turbulent air streams enter into the radial section, creating differential pressure between the input and output pipes. This means that the flow of side channel blowers decrease as pressure increases. 

Side channel blowers’ varying capabilities make them a good fit for continuous and non-continuous applications that require a mix of pressurized and non-pressurized solutions, including:

  • Vacuum lifting
  • Dry blowing
  • Point suction
  • Aeration of biological processes
  • Plastics manufacturing

5. Regenerative Blowers

Regenerative blowers are unique because they move air using non-positive displacement, which is how they get their other name —  high-flow, low-pressure mechanisms. Instead of trapping air and forcing it to move, they allow some air to pass over a blade, and then move it forward using another blade. Air is usually circulated in one or two stages. 

Regenerative blowers are well-suited for applications that require high rates of air flow at a low pressure, or that require a vacuum. This could include things like:

  • Sewage aeration
  • Concrete aeration
  • Vacuum lifting
  • Vacuum packaging
  • Pneumatic conveying
