Different Industrial Exhaust Fan Types & Their Applications

February 09, 2023


Industrial exhaust fans are an essential element of industrial air ventilation systems. They help to remove harmful fumes, smoke dust, and other contaminants from the working environment. Industrial exhaust fans are available in various styles, including high-end ceiling exhaust fans, wall-mounted exhaust fans Industrial blowers, and ceiling fans. Each one comes with its distinct features and functions which make it ideal for various industrial settings. In this article, we'll look at the different kinds of industrial exhaust fans and their numerous uses.


There are differences between ventilation fans and exhaust fans.


Both exhaust and ventilation fans work together to produce the freshest and pure air that is possible within the area within which they are situated. The primary difference between the two kinds of fans is their use. A ventilation fan is used to circulate clean air through an enclosed space, it is a source from outside while an exhaust fan is used to remove contaminants from the indoor air of a home or commercial space.


Types of Industrial Exhaust Fans


Roof Mounted Exhaust Fans


This kind of fan is affixed to the roof, and it releases air from the area where it is installed through an opening in the roof.


Inline Exhaust Fans


For rooms that aren't well ventilated in the room, inline exhaust fans are often the best option. They are installed between the ducting and help to eliminate polluted air from the ducts.


Belt Drive Exhaust Fans


Fans that are driven by belts are fitted with a belt that is connected to the shaft of the rotor and motor. They assist in removing dust and heat and provide the quietest operation. This kind of design of exhaust fans also gives greater control for a user than direct drive fans.


Wall Exhaust Fan


A wall-mounted exhaust fan is the kind of exhaust fan typically used in homes, particularly those with walls that are directly in front of open spaces.

This kind of exhaust fan is easily mounted using a simple installation. The exhaust fan is also efficient in sucking out the dirty and stuffy air from your house. This kind of one also doesn't require the use of a mechanical Ventilation Heating Recovery System (MVHR) or specially designed exhaust ducts.

Usually, wall-mounted exhaust fans aren't only ideal for use in the living room or bedroom, however, but they are also ideal for use in the bathroom or kitchen.


Backward Curved Centrifugal Fans


Backward-curved centrifugal fans possess less large blades that could be aerofoil segments, which typically are curved away in the direction of the rotation. Maximum power and speed can be seen to overlap at the midpoint of the curve of the fan and, as long that the motor is designed to function at this point, the fan can be classified as having the "non-overloading characteristic". 

The fan can be used without or with a scroll housing, which gives an array of design options. 

This kind of fan has more speed to create pressure than forward-curved fans of the same size. The backward-curved fan, such as the latest Wheel style is by far the most energy-efficient among all designs of impellers. it is commonplace that large fan systems usually employ backward-curved fans for smaller energy consumption.


Exhaust Fan Cooker Hood


A cooker's exhaust vent works to circulate the air created during cooking using the exhaust air conduit. The exhaust fan cooker hood efficiently gets rid of cooking smells and gases from burning while cooking.

When you install the cooker hood for exhaust fans it is important to be aware of the direction that the air will go. You can then attach it to the wall and then channel the air directly to your wall in front of the mount.

This device uses an air filter to get rid of the cooking smells. The air is then recirculated into space. The hoods all have an oil filter, as well as activated charcoal or carbon filter that neutralizes the smells you produce while cooking.




The range in industrial exhaust fans allows them to be used for a variety of purposes, including:

  • Clean air handling: They can be found in industrial systems components or work to move huge amounts of air. Exhaust fans improve the air quality inside the facility and the equipment.
  • The dust load is light: Exhaust fan exhausts can efficiently move and collect dust and prevent dust from accumulating in equipment or all over the facility.
  • Material handling: Many particles are often accumulated in industrial settings. Exhaust fan exhausts can handle larger particles, including wood chips, sawdust grain, wood chips plastic pellets, and much more.
  • Fans of saturated air: If there is a significant amount of humidity or moisture present in the air it's called saturated air. Centrifugal exhaust fans are often used to remove the air, thus preventing the accumulation of moisture that could result in mold or corrosion.
  • High temperatures: Certain industrial processes such as heat treatment can result in extremely high temperatures that require special equipment. Exhaust fans can safely circulate hot air in these extreme conditions.
