Ingersoll Rand 5-HP 60-Gallon Single-Stage Air Compressor (230V 1-Phase)

21.5 Amps on this model. I've loaded the Manual and the Spec Sheet as downloadable PDF files under the Specs tab for you.

An air tool requires air flow to work.

Think of a windmill. A slight breeze lacks the power to turn the blades. However, a hurricane-force wind can generate substantial power.

Some air tools consume more air than others. Nailers and staplers require a puff of air. Sandblasters and sanders need massive gusts.

So, you basically want to know how fast the air comes out of the compressor. The air flow is measured in Cubic Feet Per Minute (CFM). The greater the flow -- the greater the power.

You simply select an air compressor that exceeds the CFM of your most powerful air tool. If the flow isn’t strong enough, the air tool simply won’t perform properly.
We recommend sizing the compressor 1.25-1.5 times the CFM of your tool for continuous operation. If the compressor does not produce enough air volume, CFM, then the pressure will drop.
Reciprocating (Piston) compressors are not designed for continuous or 100% duty cycle. The compressor will cycle off & on if it is sized correctly.
A two stage compressor compresses the air twice resulting in a maximum air pressure of 175 psi. A single stage compressor will only achieve a max pressure of between 125-135 psi.
Air flow, CFM, is generally the most important spec when sizing a compressor.
