The bigger concern for most Pros is SCFM – the volume of air it can deliver. Ridgid’s 5.0 SCFM at 90 PSI is right on par for this class, though it does drop behind slightly for its 40 PSI rating. That will run all of your nailers along with 1/2-inch or smaller impact wrenches, most air ratchets, and some grinders. You won’t have enough air to run sanders, large grinders, and shears.
What that means for the Ridgid 15-Gallon Air Compressor – and the class, in general – is that this makes a great job site compressor, but gearheads and hard-core woodworkers will need more.
If there’s an area that Ridgid stumbles, it’s in its decibel rating. While the other 2 are humming along at 78 dB(A), Ridgid is a full 8 points higher at 86 dB(A).
