  Understanding PSI and CFM

Pressure and Capacity

Pressure and capacity are the two main specifications to consider when buying an air compressor.


  • Pressure is expressed in PSI (pounds per square inch).
  • Capacity is expressed in CFM (cubic feet per minute).

The difference between a large compressor and a small compressor is not the size of the tank or the pressure…It is the capacity of air flow (CFM) the compressor produces.


Simply put, CFM performs the work PSI dictates how fast the work gets done.


What pressure (PSI) do I need?

Look at the tools or machines you use. Every tool or piece of machinery has a required minimum operating pressure. Generally, tools are between 80-100psi. For larger industrial machinery, check the technical specifications for that specific machine. If you cannot find the psi and cfm requirements contact the manufacturer to get the correct pressure and flow needs of your equipment.


What size/capacity (CFM) do I need?

Capacity is the amount of air that the compressor can pump out. It is expressed in CFM (cubic feet per minute). CFM is one of the main factors to consider when selecting the right compressor. You will need to know the cfm requirements of the tools and/or machinery that your compressor will be operating.

  • The Capacity of the compressor is measured in Cubic Feet per Minute, NOT in gallons or liters. This means tank size is not necessarily related to choosing the size of the compressor.
  • When replacing an old air compressor it may be helpful to know for reference purposes, that reciprocating compressors produce approximately 3.2 cfm per horse power and rotary screw compressors produce approximately 4.2 CFM per horse power.

Air compressors can be a significant investment for business owners, so it is important to understand the factors that affect performance before you buy. As you weigh your options, evaluate your shop’s current CFM requirements, but also forecast your future demands. Are you planning to add technicians or equipment to expand your business? If so, then you may want to purchase a larger compressor.


To Determine CFM

It’s always best to get an accurate measurement of your current air usage if possible. However if you have a small system a good rule of thumb is to add up the CFM (Not pressure!) requirements for all the air tools and machines that you have. This would be the maximum air capacity required if all of your equipment were to operate at the same time - which is rarely the case. If you operate 60% of your equipment at once multiply the total number by 0.6, if you operate only 40% multiply by 0.4 and so on. Add 10% to the total number. If you already have one or more compressors and need to purchase a replacement machine, it is still recommended that you evaluate the changes that may have occurred in your system and size a replacement compressor to accommodate growing needs.
