Which is the best piston air compressor to buy? If you are using your piston air compressor inside electric would be the one to go for but if you are wanting a portable piston air compressor you can choose either the diesel or petrol models depending on what type of fuel your other equipment is using.

Brad Nailer  .03 CFM, Chisel/Hammer  3-11 CFM, Drill, Reversible or Straight-Line  3-6 CFM, Dual Sander  11-13 CFM, Framing Nailer  2.2 CFM, Impact Wrench – 3/8″  2.5-3.5 CFM, Impact Wrench – 1/2″  4-5 CFM, Orbital Sander  6-9 CFM, Ratchet – 1/4″  2.5-3.5 CFM, Ratchet – 3/8″  4-5.5 CFM

It stands for Cubic Feet Per Minute, the amount of air a piston air compressor delivers, measured in cubic feet in a minute. Just be aware that CFM a compressor delivers changes, depending upon the psi (pounds per square inch). Most air tools have a CFM requirement for volume and pressure. When choosing a piston ring compressor, think of the tool you are planning to use that requires the highest CFM, and add a small amount to that number for a margin of safety. For example, if a tool requires 3 CFM at 90 psi, select a reciprocating air compressor that delivers at least 4.5 CFM at 90 psi.

A reciprocating compressor or piston air compressor uses pistons driven by a crankshaft to deliver air at high pressure. A piston moves downwards, reducing the pressure in its cylinder by creating a vacuum. The up-and-down motion is called a reciprocating motion and that's why its called a reciprocating compressor
