Axial Fans

Axial fans are not new to the industrial world. As a matter of fact, they are the most common type of propeller fan on the market today. When looking at the construction, actual physics are not much different than you would expect. The fancy names for axial and centrifugal industrial fans simply mean they move air along the same access as the power source that generates the rotation.

You may already be familiar with cooling fans like ceiling fans or box fans. Each of these applications will push the air axis parallel to the rotation and each of them helps to cool the area around them by boosting airflow.

Industrial and commercial facilities must control the air to provide compliant, safe, and clean working conditions. An axial fan is a popular tool when ventilating spaces and moving air. When looking at axial fans vs. centrifugal fans, you want to know how they work, their suggested applications, and which options are best for your unique facility and needs.

What Are Axial Fans?

As mentioned, an axial fan moves air running parallel to the motor shaft to create a consistent, precise flow. Spinning blades work to control movement while the air intake and discharge happen to move in the same direction. When axial fans are used, they create improved ventilation with low-pressure air movement. The fans may be noisier than other styles, but they are often lighter and smaller and might be able to get outfitted with silencers. The fan's number of blades usually impacts the noise output.

Axial Fan Blades

The industrial fan blades for axial fans are “wind-tipped” or tapered to help cut back on turbulence. Different blades and the materials that make them can move the air differently. Many axial fans have blades constructed from:

  • Stainless steel
  • Steel
  • Cast aluminum
  • Glass-reinforced polyamide (PAG)
  • Glass-reinforced polypropylene (PPG)

Both PAG and PPG blades are good for use in different environments, especially corrosive or wet ones.

When selecting blade materials, you must consider the application, especially for your work environment. If you work in temperatures over 175°, your axial fans should have industrial-grade materials like sheet metal or aluminum. Cast aluminum is lightweight and durable, which makes it a good choice for fan blades.

Axial Fan Construction

Along with the blades, the fans include several other parts like the motor, impellors, and housing. The axial blower comes in a few categories, including vaneaxial, tubeaxial, and propeller. The propeller axials have two or more blades rotating in the frame, while a tubeaxial style mounts via a tube to generate a spiral discharge. The vaneaxial design is similar to tubeaxial, but it features stationary vanes to cut back on the swirl when releasing the air. Regardless of the type of axial fan, each is engineered to address a large quantity of air movement with low static pressures.
