- Temperature regulation
Industrial spaces and factories usually experience high temperatures. An exhaust fan helps in regulating these high temperatures by removing hot air and bringing in fresh, cool air.
This can keep your workplace more comfortable and even helps by preventing the issue of equipment overheating.
- Improved air quality
Another significant benefit of these exhaust fans is that these can improve the air quality to a great extent. In many factories, procedures can release harmful dust, gases, or chemicals.
These industrial exhaust fans help by eliminating these harmful elements from the air and making the area healthier.
- Prevention of mold and moisture
In some industries, moisture may aid in mold growth. These exhaust fans can easily remove excess moisture from the atmosphere and control humidity levels.
- Increased productivity
If a workplace is properly ventilated then it usually becomes more comfortable for workers. When employees do not have to work within poor air quality, their productivity may increase a lot. Moreover, proper ventilation can reduce the incidents of health-related absences, eventually boosting efficiency.

- Consider Key Parameters
While choosing the right industrial exhaust fan, it is important to check out the key parameters carefully. Those parameters are discussed below.
- Air Temperature
The temperature of the air that goes through the blower or the fan usually affects the performance of the blower or fan. Thus, it is a vital factor that you must check out.
- Density
Usually, density changes due to variations of temperature and barometric pressure. Hence, you must correct these situations carefully before choosing the right industrial exhaust fan for your workplace.
- Static Pressure
Static Pressure is actually the resistance to friction or airflow that is caused when the air moves through a duct, pipe, filter, hose, air control dampers, and hood slots.
This Static Pressure is rated in inWG or inches water gauge or the metric equivalent, mmWG or millimeters water gauge. (1 inWG = 25.4 x mmWG)
- Airflow Rate
Airflow rate is actually the quantity of air that passes through an industrial fan over time. This airflow is rated in CFM or cubic feet per minute, or the metric equivalent M3/Hr or cubic meters per hour. (1 CFM = 1.6990 x M3/Hr.)
- Altitude
The actual altitude at which the blower or the fan will be functioning may have a significant effect on the performance of the fan.
- Ambient Temperature
The ambient temperature, or the temperature of the air outside the blower or the fan, may have a strong effect on the operation of the blower or fan. Though the vast majority of fans usually blow air at room temperature, there are still some that must operate under certain environmental conditions or temperature.
- Noise Level
If loud sound is a problem, then you may look for some high volume-low speed commercial ceiling fans or industrial exhaust fans that do not make loud noises.
Usually, small fans require to run at quite high speeds, as in this way, they can maximize airflow. However, as a result, they make a lot of noise.
Some Other Factors
Other than the key factors mentioned above, there are some other additional factors, that you should check out while buying the right industrial exhaust fans. Those are as follows:
- Installation and Maintenance
There are some fans that are quite easier to install than other types of fans. You just have to make sure that your workplaces have enough space and proper mounting options for the industrial exhaust fan you select.
Moreover, you need to look for fans that are very easy to maintain and clean. You may look for features like accessible filters and bearings that can simplify maintenance tasks.
- Build Quality and Durability
You must check for solid construction and quality components in your industrial exhaust fans. If you choose a well-built fan that it will have a longer lifespan and require fewer maintenance issues.
If your industrial exhaust fans are made of strong elements like aluminum or galvanized steel, then it will surely last longer than other types of fans.
- Energy Efficiency
It is important to look for industrial exhaust fans that have high-efficiency motors. These types of fans usually consume less power and hence can optimize energy use. Moreover, you may check out fans with variable speed drives that can adjust the speed of the motor according to demand, eventually optimizing energy use.
- Size and Capacity
You need to check the size of these industrial fans as larger fans can move more air. So, if you have large workplaces, you must get fans with larger diameters. Moreover, you can opt for fans that have multiple speed settings. This feature will help you to adjust the airflow as per your needs.
So, you need to carefully check the detailed specification of the right exhaust fan. For these details, you may check the specifications given by the fan-manufacturer.
Hence, no matter if you need an industrial exhaust fan or fans for cooling, ventilating, or drying out, considering these vital factors is always important.
Things to Consider while Choosing the Right Fans
Before choosing the right kind of industrial exhaust fan for your workplace, you need to check out some vital things, including types of fans. So, let’s take a look.
- Asses the environment
In the procedure of choosing the right kind of industrial fan, the characteristics of the surrounding environment play a vital role. Open areas, high ceilings, or even any kind obstruction may affect the efficiency of air circulation to a great extent. Areas where people work within dust or chemicals may require fans in order to maintain the right working conditions.
- Sort out Your Requirements
Before choosing the right industrial exhaust fan for your workplace, you have to find out what you actually need from this ventilation system. Thus, you have to consider the type of activities your workers conduct, the size of the area, and also the average number of workers who work in that area during peak times.
This will help you to find out the actual volume of air movement that this area requires maintaining proper working conditions for your employees.
Types of Fans
Industrial fans operate in different ways. Two most common types of industrial fans are Axial Fans and Centrifugal Fans.
- Axial Fans
These types of fans are made of a propeller that rotates on its axis with the help of a motor. It can move the air in an axial direction through a formed orifice panel or a cylindrical housing.
These fans are usually used for lower pressures and higher flows. Generally, an axial fan is used for desired air circulation in large spaces, ventilation of rooms through ducting, and walls. If you compare an Axial fan with a centrifugal fan, then the axial fan usually occupies less spaces, are quieter, and also less expensive.
- Centrifugal Fans
Centrifugal fans are also called radial fans. These are another type of industrial fans that have an impeller or a wheel. This wheel can draw air into the housing inlet, can turn about 90 degrees and accelerate radially, and then exits the fan housing.
These centrifugal fans are generally used for higher pressures and lower flows. These are also very quieter and hence, can be perfect for your workplace if you don’t like loud noises. However, they are more expensive and take up more space than Axial fans.
- HVLS or High Volume Low Speed Fans
These are another type of industrial fans that are suitable for large spaces. They can circulate large volume of air at low speeds, and hence, can offer energy-efficient cooling.
- Inline Fans
These types of industrial fans are generally installed in ducts and they can move air through long distances. These Inline fans are often used in HVAC systems.
Hence, industrial exhaust fans play a vital role in maintaining the right environment within your workplace. However, you need to choose the right type of fans to give your employees a perfect working environment.
