Comparing The Role Of CFM And PSI In Industrial Filters

Cubic feet per minute (CFM) and pounds per square inch (PSI) are two common metrics used in industrial filters. What is the main difference between these two measurements? In this blog, Dynamic Filtration Ltd., a major manufacturer of industrial filters, filter elements, and custom filters in Waterloo, Ontario, explores the differences between CFM and PSI in detail.

 

 

What Is Cubic Feet Per Minute In Industrial Filters?

Cubic feet per minute (CFM) is defined as the amount of air flowing through the industrial filter per minute. It is a key metric in industrial filters as it indicates a filter’s application. The higher the CFM, the lower the filtration efficiency.

 

 

What Is Pounds Per Square Inch In Industrial Filters?

Pounds per square inch (PSI) is more of a measure of pressure being exerted on the filter element. It is defined as the amount of pressure being exerted on a single square inch of the industrial filter. This is a key metric to consider for OEM and custom filters, as all filters need a minimal amount of pressure to operate effectively. 

 

 

How Are CFM and PSI related to each other?

In the context of industrial filters, CFM and PSI are inversely proportional to each other. This means that as CFM increases, PSI will reduce and vice versa. Hence, while choosing a filter, it is important to consider its application. If better filtration is desirable, then a higher PSI and lower CFM will be a better choice. Conversely, for applications such as an HVAC system, the CFM needs to be moderate or high to enable easy air flow, thereby reducing the PSI rating.

 

 

Conclusion

In closing, CFM and PSI are two key metrics used to rate an industrial filter. However, the two are distinct from one another and are considered inversely proportional.

FAQs:

 

What is the maximum CFM in industrial filters?

The maximum CFM in industrial filters defines the amount of airflow a filter can handle without adversely affecting filtration efficiency.

 

How to ensure a high CFM without dropping pressure in industrial filters?

To ensure a high CFM without compromising on pressure, industrial filters are fitted with large housings to ensure the pressure drop is minimal.
