22 CFM
This 22 CFM air compressor category groups units by rated airflow so you can filter results instead of sorting the full catalog. It exists to narrow the field to a specific delivery level, and the central check stays the same: confirm each compressor's delivered CFM at the working PSI your tools actually require.
Matching 22 CFM To Working Pressure
A 22 CFM rating only means something once you know the pressure it was measured at, because the same compressor delivers less air as required pressure climbs. Check each product page for the PSI at which airflow is stated, then compare that against the pressure your tools or processes actually roerate. If a listing quotes airflow at a lower pressure than you need, its usable delivery at your working PSI will be less than the headline figure suggests.
Checking Air Demand At 22 CFM
Total the air every tool or process draws when running together, then set that figure against a compressor's rated 22 CFM delivery. Allow a reasonable operating buffer above your total so recovery keeps pace with steady use. If your verified demand lands below this level, the 20 CFM air compressors category may fit, while demand that sits close to the number is worth weighing against the 25 CFM air compressors for added margin. Keep in mind that a single stage air compressor would need to produce twice the required CFM to allow for duty cycle and a two stage anywhere from 25 to 40%. No piston air compressor is rated for 100% duty. A rotary screw air compressor can be sized closer to the required demand because it can run at 100% duty.
FAQ:
Does running more than one tool change what I need at 22 CFM?
Yes. Simultaneous tools or users add their airflow demands together, so two moderate tools at once can exceed 22 CFM even when each alone sits well under it.
What else should I check alongside a 22 CFM rating?
Confirm the working PSI the airflow is rated at, and review the other listed specifications on each product page rather than treating the CFM figure alone as a match.
