Ventilation ducts play an essential role in enclosed spaces where workers handle materials that produce fine particles that can affect air quality and, therefore, worker productivity and health. 

That is why industrial exhaust fans work continuously, ensuring air movement ranging from 200 cubic feet to 2 million cubic feet per minute. They are commonly used in hospitals, businesses, warehouses, or buildings. Their excellent performance ensures proper airflow while minimizing energy consumption.

The difference between an exhaust fan and an air fan

The main difference lies in the fact that an industrial air fan works as a ceiling-mounted fan for domestic use. It generates an air current that causes dust and other substances to rise, resulting in the entry of contaminants and harmful fauna that can affect product safety.

However, it is possible to have both an exhaust fan and a fan during installation, depending on the design or ventilation systems needed to determine the losses or thermal stabilization, such as with double-flow ventilation.

Types of exhaust fans

The type of industrial exhaust fan required will depend on the space's conditions and the ventilation system's design , among other factors. The two main types are:

Axial or helical: These fans consist of a chassis, a motor, and blades that are coupled according to the required revolutions. Helical extractors also include pulleys and belts for transmission. The most notable benefit of these fans is their large capacity. However, one of their disadvantages is that they generate more noise, approximately 73 decibels. The noise level depends on the location and size of the fan.

Centrifugal: As the name suggests, these fans use centrifugal force through rotation. One of their main benefits is the reduction of odors and humidity in the environment, which is why they are commonly used in the food industry. Centrifugal fans are composed of a frame, side plate, flange, blades, suction cone, and snail.

Preliminary recommendations before installation

Prior to installation, it is essential to perform preliminary studies to ensure proper operation, as recommended by the Air Movement and Control Association International (AMCA). These include:  

• For welding fumes, the recommended speed is 10-12.5 m/s.
• For very fine dust (cotton, wood flour, or talc), a speed of 12.5-15 m/s is recommended.
• For heavy dust (metal chips or lead dust), a speed of 20-22.5 m/s is suitable.
• For heavy wet dust (wet cement dust), a speed higher than 22.5 m/s is recommended.

Exhaust fans are essential for any type of industry, as they have a wide range of uses, from commercial buildings to farms. Moreover, their durable construction materials make them strong and ideal for withstanding inclement conditions while ensuring the safety and well-being of workers.
