Top 10 Considerations for Industrial Exhaust Fans

Are you unsure about what to consider when choosing an industrial exhaust fan?
Selecting the wrong fan could lead to operational inefficiencies and higher long-term costs. To avoid this, it's essential to know the key factors that determine the best choice for your industrial environment.

1. What is the right size for an industrial exhaust fan?

Pain: A fan that is too small will fail to provide adequate ventilation, while an oversized fan may lead to unnecessary energy consumption.
Agitation: Misjudging the fan size can result in poor air circulation, excessive noise, and inflated power bills.
Solution: Select the fan size based on the volume of the space and the required airflow, measured in cubic feet per minute (CFM). Large areas like factories or greenhouses typically need 24-inch or 48-inch exhaust fans, while smaller spaces can benefit from using 6-inch or 10-inch extractor fans.
Learn more about how to size an industrial fan for your specific space.
For smaller areas, consider a 6-inch extractor fan.

2. How do I calculate the airflow (CFM) needed?

Pain: Inadequate airflow can lead to insufficient ventilation, resulting in stagnant air and potential health risks.
Agitation: Without proper airflow, the environment may become uncomfortable or even hazardous for workers.
Solution: To determine the required CFM, consider the volume of the space and the frequency of air changes needed. For instance, environments that require frequent air changes, such as workshops, should utilize high-CFM options like industrial extractor fans designed for various environments.
