Manufacturing industries use industrial fans and blowers mainly for ventilation. However, they also use them to facilitate some of their industrial processes that require airflow. Since they keep some of the industrial processes running, they form an important requirement that every manufacturing industry should consider installing.
Standard Industrial fan systems consist of:
- A fan
- Electric motor
- A drive system
- Piping or duct
- Flow control devices
- Air conditioning equipment
Experts separate industrial fans, blowers, and compressors based on the method they use to circulate air. The system pressure, against which they operate, is also used to determine the type of a fan system.
Industrial fans – These exist in two main types: centrifugal fans, and axial fans. In centrifugal fans, they use an impeller to circulate air while in axial fans, air moves along the axis of the fan. If you operate a mid-size or mainstream manufacturing firm, it is advisable to consider installing commercial exhaust fans, as that can lead to improved ventilation and efficiency in industrial processes.
Centrifugal fans – With a rotating impeller, centrifugal fans are able to increase the speed of air stream. As the air reaches towards the ends of the blades, it gains more speed and turns to pressure. Due to the high pressure they produce, centrifugal fans are ideal for harsh operating conditions, making them one the best industrial fans Melbourne market has for customers.
They are suitable for places where temperatures are high, and places with moist or dirty airstreams. Based on the nature of their blades, centrifugal fans fall under three categories namely radial, forward-curved, and backward inclined centrifugal fans. Each type of centrifugal fan has its advantages and downsides.

As for radial centrifugal fans, they are ideal for places with high temperature and high static pressures. Their design is simple, making it easy to customize for special applications. In addition to that, radial centrifugal fans are designed to operate in areas with low or medium airflow rates without causing vibrations. They are highly durable and efficient, with their efficiency going up to 75%. The only downside of radial centrifugal fans is that they are only applicable in low to medium airflow rates.
In forward-curved centrifugal fans, they are ideal in moving large volumes of air. They are relatively smaller and produce low noise level, making them suitable for residential applications. They can be used for ventilation and air conditioning purposes. However, they also come with their downsides. For example, they have low energy efficiency and users have difficulty in adjusting the fan output. Besides, they are only suitable for clean areas and not for heavy-duty operations where high pressure and harsh services are required.
Backward-inclined fans are the best with efficiency of up to 85 percent. However, they are not applicable for dirty and harsh applications.
