When it comes to choosing air tools and you’re reading up on your air compressor specifications, it’s good to know what some of the abbreviations stand for, like PSI and CFM.

Not only this, but what the difference between them is and why they are important. Don’t worry, we’ve got you covered! Here is everything you need to know about PSI and CFM, including their relationship.

Essential Information About PSI & CFM


What Does PSI Stand For?

PSI stands for Pounds per Square Inch. Simply put, it measures the air pressure within an area, specifically how many pounds of air pressure in one square inch. This is an important measurement because the air pressure determines how powerful the compressed air is.

What Does CFM Stand For?

CFM stands for Cubic Feet per Minute. Particularly for air compressors, CFM measures how much air can move per minute. This is an important measurement because the rate of air flow determines how much air your compressor is producing.


How Do They Relate to Each Other?

As mentioned above, the difference between PSI and CFM are what they measure, but both measurements are vital when it comes to both air compressor and air tool operation.

They are referred to as performance specifications and indicate whether an air compressor will sufficiently power air tools. When you purchase new air tools, it is important to check these capacities beforehand against your air compressor performance specifications. If they both meet the air requirements of your air tools, then your air compressor will power them sufficiently.

It is essential that you maintain both air pressure and air flow rates of your air compressor in order to guarantee the proper functioning of your applications. These measurements are essential to your operation, so don’t dismiss them.
