An air compressor's CFM specifications must also include atmospheric pressure, ambient air pressure, temperature and humidity, in order to get accurate and comparable numbers. The term standard cubic feet per minute (SCFM) incorporates these variables.


Air Compressor Buyers Guide – CFM vs. SCFM. Air compressors come in many different sizes and variations. There are different horsepower motors, different size tanks and different piston configurations . But perhaps more importantly, all of them are rated in cubic feet per minute, or CFM of compressed air.

The distinction between SCFM and CFM is important because air density changes with pressure and temperature. This can be seen from taking a look at the ideal gas law. ...

The air compressor industry is full of acronyms for measuring airflow or consumption. Two common measurements are ACFM and SCFM. ACFM (Actual Cubic Feet per Minute) may have different definitions depending on the industry. VMAC defines ACFM as the true air mass flow given a certain set of real life conditions.


This page is providing information about SCFM and the measuring of compressed air flow. Since SCFM is the measurement of free air flow, confusion with how this applies to compressed air flow, and even above questions about compressors themselves, is an issue that draws a steady stream of visitors to this air compressor information website.


I will plagiarize the Roots SCFM vs ACFM Guidebook to offer the correct calculation for air. In specifying blower performance, major problems occur in distinguishing ACFM from SCFM, and in correctly converting from one to the other. Some people even use SCFM and ACFM interchangeably.


SCFM, which stands for standard cubic feet per minute, is a numerical rating that shows the quantity of air flow a pneumatic tool requires to function at peak performance. The actual value varies based on the pressure exerted by the air in the compressor, which is typically measured in pounds per inch.


SCFM versus ACFM and ICFM Actual air compressor capacity (ACFM) versus standard air capacity (SCFM) and inlet air capacity (ICFM) ... ACFM = Actual Cubic Feet per Minute. SCFM = Standard Cubic Feet per Minute. P std = standard absolute air pressure ... SCFM to ACFM. The actual CFM of a compressor operating at "non-standard" conditions like ...


Partly for the sake of comparing products, manufacturers sometimes express capacity in Standard Cubic Feet per Minute (SCFM), which assumes a standard temperature and pressure. If you have an application that calls for a certain capacity at a specified temperature and pressure, and the capacity of the system you are considering lists capacity ...


CFM: Cubic feet per minute is the volume of air being delivered by the compressor to the air tool. This number is used as a measure of the compressor’s capabilities — and it’s the most important rating when choosing an air compressor. Compressors with higher cfm ratings provide more air, which makes them more practical for larger jobs.
