28 CFM

Matching 28 CFM To Working Pressure

A 28 CFM rating only means something once you know the pressure it was measured at, because the same compressor delivers less air as the 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 operate. 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, and the 30 CFM air compressors category may be worth weighing for added margin.

Matching 28 CFM To Intermittent And Sustained Demand

The application determines what 28 CFM can cover. Intermittent, single-tool work pulls air in bursts and tolerates a tighter figure, while sustained tools and simultaneous users hold demand steady with less room to spare. Compressor type factors in too: a two-stage piston would need to produce anywhere from 25 to 40% more than the required CFM to allow for duty cycle, and no piston air compressor is rated for 100% duty. A rotary screw can be sized closer to the required demand because it runs at 100% duty. A verified lighter load may point to the 25 CFM air compressors range.

FAQ:

Does running more than one tool change what I need at 28 CFM?
Yes. Simultaneous tools or users add their airflow demands together, so two moderate tools at once can exceed 28 CFM even when each alone sits well under it.

What else should I check alongside a 28 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.
