Employee safety and well-being are of utmost importance in industrial settings. Several considerations must be taken into account to achieve this goal, including the preservation of air quality in confined areas that are frequently exposed to high temperatures, humidity, exhaust fumes, and airborne chemicals. Fans and blowers are essential in these situations because they remove stale air and bring in fresh clean air.
This is why various sellers offer a broad selection of industrial fans as well as blowers with a variety of options for flow direction, speed, & volume capacity to meet the requirements of a wide range of clients and applications.
In addition to centrifugal and axial fans, the products are used in a wide range of industries and applications, from biotechnology to education to food and beverage to manufacturing.
The warm and humid air is replaced with fresh air by exhaust fans. Fresh air enters through a vent or even a door after being sucked out of a small area by exhaust fans.
Types of Industrial Exhaust Fans
Blowers and fans improve airflow and air quality in industrial ventilation systems. Even though their functions are very much alike, they operate according to slightly different rules.
To move air, fans use rotating blades that create low-pressure generalized circulation. When it comes to propelling air at high speeds, blowers rely on wheels.
They are available in two types
→ Centrifugal fans
Using blades that rotate at high speeds, centrifugal fans increase airflow velocity and pressure. At a 90-degree angle, the air leaving the fan travels. Aside from their higher pressure capacity, they are often used in harsh and corrosive environments because of their high level of chemicals, dirt, humidity, as well as other contaminants.
Centrifugal fans could be designed with forward-curved and backward-curved blades. Smaller air volumes can be moved by forward-curved blades with less sound, while larger air volumes can be moved by backward-curved blades with greater efficiency.
→ Axial fans
However, unlike centrifugal fans, the intake & discharge of axial fans are done in a straight line. They are perfect for shifting large amounts of low-pressure, clean air into and out of space frequently.
Exhaust & ventilation systems for storage facilities, paint booths, heaters, and sewage pump stations are common examples of these systems’ applications.

How To Choose The Industrial Exhaust Fan?
As soon as you’ve decided whether an axial or centrifugal fan is the perfect suited for your facility, there are several other important considerations to keep in mind. Among the many examples that could be cited are:
1. Belt drive Vs. Direct drive
A direct-drive fan is noisier than one that uses a belt or pulley system. Belt-driven fans, on the other hand, are more efficient and require less maintenance than direct drive models. Belt-driven motors are almost universally used in high-temperature fans operating above 120 degrees Fahrenheit.
2. Fan location
For example, wall, roof, and air duct fans all have unique designs and models that are tailored to their specific locations. Functioning components are the same regardless of the location. You can choose the best location by analyzing the structure of your building and determining how well the air should flow.
3. CFM or cubic feet per minute
When a fan is running at full power, the amount of air moving through the room is measured in cubic feet per minute (CFM). To effectively cool and ventilate a room, the CFM should be increased. According to local building codes, CFM ranges are typically specified.
4. Static pressure
As the name suggests, static pressure refers to the amount of force a fan must exert to move the air in a particular direction against a fixed amount of resistance. No air will move unless the force pushing or pulling it is greater than the force resisting it.
5. Noise level
It is possible to gauge the volume of noise produced by a ceiling fan using both decibels & sones as units. A product’s noise level is determined by its Sone rating. The sound level of a sone is about 40 decibels louder than that of a typical volume. As an example, two sones inside a personal home to between 25- 50 sones in a production plant can be considered appropriate.
6. Air quality
There must be a certain amount of air movement for your exhaust fan to work properly. So figure out the amount of airflow your kitchen and bathroom exhaust fan needs, and then look for a fan that can support that amount of airflow.
7. Cleaning
Buying an industrial exhaust fan that is easy to clean is the best option. Even though many exhaust fans on the market do an excellent job, they are notoriously difficult to maintain. Make sure the exhaust fan you choose can be cleaned easily, as well as efficiently.
8. Warranty
To get a replacement for your exhaust fan if it breaks, you should look for a manufacturer’s warranty of at least 1-2 years on the product.
Conclusion
Industrial exhaust fan is the best option to go for, according to the experts. With a 2-year manufacturer’s warranty, a robust design, a backdraft shutter, bearings, an HP motor, and a reasonable price, the affordable exhaust fan can be an excellent choice. You can get your hands on the best exhaust fan based on the features it has to offer.
