Commercial fans are built to be tough. They need to work long and hard, be able to withstand extreme temperatures, and hold up when knocked and bumped around. Air conditioning and venting for commercial buildings is the most obvious application for commercial fans. But here are some other applications you might not think of that call for the use of durable, commercial grade fans.
- Other transportation such as buses and trains
- Refrigeration units
- Cooling towers
Here are some of the standard types that can be used to address these applications.
Axial flow fans should come with sturdy aerofoil section bladed impellers. Die cast aluminum is a good choice that will allow the fan to withstand temperatures up to 300 degrees centigrade for four hours at a time. These fans are useful for smoke and other high volume ventilation needs. They can come in direct or belt-driven models.
Bifurcated fans are mainly used in industrial applications. They are designed to handle air and fumes while withstanding hot temperatures.
These fans consist of impellers that are mounted directly onto the motor. This makes them extra sturdy while allowing for manual adjustment of the pitch.
Mixed flow fans are often used as roof extract fans and can handle a variety of needs with high efficiency.
These are the fans you want if a mixed flow unit is not enough. They are used as roof extract fans for industrial grade ventilation.
Centrifugal fans are available in either backward or forward curved bladed designs. Either design can come with a single or double inlet unit arranged in a variety of ways to accommodate space and function.
Since commercial fans are highly powered, they can often be noisy as well. It may make sense to purchase a sound attenuator along with the fan. These appliances can be used to dampen or virtually eliminate fan-produced noise in air conditioning and ventilation systems.
