An efficient ventilation system is essential for any quality business, but they come with so many separate components it can be difficult to know where to start. As all systems are made up of fans and blowers, the best place to start is knowing the difference between common fan types.


Centrifugal Fans And Blowers


These fans resemble oversized hamster wheels, and work by drawing air into the center of the fan and then exhausting it at a 90 degree angle. Smaller examples of centrifugal fans lie in hair dryers, vacuum cleaners, and home furnaces. Of all fans and blowers, they are able to operate against a very high resistance. Centrifugal fans are typically used in exhaust ventilation systems, and their subcategories are determined by the type of fan blades:

  • Radial
  • Forward Curved
  • Backward Curved
  • Airfoil

A rugged radial blade centrifugal fan is the best type to exhaust heavy amounts of dust, as they are the least likely to become clogged or abraded by dust. Centrifugal air blowers are also used in HVAC systems. Their incredible pressure output, as seen in high pressure centrifugal blowers, make them ideal for cleaning equipment and automotive applications. With this type of high-performing equipment, it is important to keep it in a well-ventilated area below 104 degrees Fahrenheit for maximum longevity.


Axial Fans


These fans look more like traditional fans that would be free-standing. They function by drawing air straight through the fan, and they are made in three basic types:

  • Propeller
  • Tubeaxial
  • Vaneaxial

Typically, propeller fans are used for dilution ventilation or cooling and are mounted in a wall or ceiling. They can move a large amount of air, as long as there is little resistance. Unlike centrifugal fans, they are not suited for material conveying as they do not generate enough suction to draw the particles through the system. These types of fans are often used as automobile radiator fans. Tubeaxial and vaneaxial fans have the same design as propeller fans, but they are designed to fit in a duct. Typically, they are used to supplement the duties of exhaust fans by moving the air through air ducts.
