The main difference between single- and two-stage compressors is the number of times that air gets compressed between the inlet valve and the tool nozzle. In a single-stage compressor, the air is compressed one time; in a two-stage compressor, the air is compressed twice for double the pressure.

Air Compressor Motor Function: Electric motor is a kind of equipment that converts electric energy into mechanical energy. It uses the electrified coil to generate the rotating magnetic field and act on the rotor to form the magnetoelectric rotating torque
Motor Classification and Component: Motors are divided into DC motors and AC motors according to the different power supply. Most of the motors in the power system are AC motors, which can be synchronous or asynchronous motors. The direction of force movement of electrified wire in the magnetic field is related to the direction of current and magnetic induction wire. The working principle of the motor is that the magnetic field acts on the current to make the motor rotate

Determine which one requires the highest CFM at the highest PSI. Add 50% to the required CFM for a margin of safety, and look for a compressor that meets the requirement. For example, if a tool requires 3 CFM at 90 PSI, select a compressor that delivers at least 4.5 CFM at 90 PSI.
The rotary vane mechanism is simpler, more durable, and more efficient than reciprocating compressors (also called “piston compressors”), and the result is a better machine — one with more uptime, better energy efficiency and cost-effectiveness, higher air quality, and a longer lifespan.
Improved efficiency: Two-stage compressors perform less work to compress air to a given pressure, which means your operating costs are lower. Better reliability: The intercooling stage of two-stage compression creates less chance of overheating, which in turn means more uptime and better productivity.
Note that if you do leave them pressurized and the air inside has moisture you may risk corrosion damaging the check valve (and if you leave the compressor plugged in and on, this could cause the compressor to fire on and run indefinitely until you catch it or it trips a breaker).
In my experience, the smallest size air compressor that you need to run an impact wrench is 6 gallon. With a 6 gallon compressor, you should be able to work for a couple of minutes before you run out of stored air.
