Determining the volume of air an air compressor delivers per minute is essential for matching the tool or application’s needs. Cubic Feet per Minute (CFM) quantifies this air delivery rate. A common example involves using a compressor to power a pneumatic tool; if the tool requires 5 CFM at 90 PSI and the compressor provides only 3 CFM at 90 PSI, the tool will not operate correctly, potentially leading to performance issues or damage.
Accurate assessment of air flow is critical for efficient operation and preventing equipment failure. Historically, estimation was based on theoretical calculations, but practical testing methods have evolved to provide more realistic and reliable values. Selecting an appropriately sized compressor prevents unnecessary energy consumption, reduces wear and tear on the unit, and ensures consistent performance of connected equipment.
