Best Air Compressor Overall

Each of these air compressors deserves the title of best for some quality or combination of qualities. Which one is best for you is something you will have to decide because only you can know your needs. Whether you want to run a sander or two, inflate a tire, or run a finish nailer, there is something on this list that will do the job you need done.

Buying an air compressor is like buying a truck. The question in both cases is the same. Before you make your choice you have to know. How much load do you have and how long do you need to carry it? In order to know your compressor’s load you have to look at the ratings of all the tools you intend to run At The Same Time. Add them up and then add some so the compressor does not have to run all the time.

5.5 cubic feet per minute (cfm) at 90 pounds per square inch pressure (psi) is as much air as you can expect from a compressor running off of a standard 15 amp 120 volt circuit. It has to do with the torque required from the motor driving the pump and the electricity available to power the motor. If somebody could get much more than that they would not be selling you a compressor they would be on their way to Stockholm to collect their Nobel Prize. So the 2 larger capacity compressors I recommend require 230 volt single phase power. This is the type of circuit that runs a clothes dryer.

Features: All of these compressors have oil cooled pumps. This not only makes them quieter it greatly increases their life compared to oiless compressors. It is also an indication that the manufacturer was building a serious tool not a cost cutter for a price. They all come with gauges, drain valves, and standard fittings ready to screw in the fittings and put it to work.
In addition to the compressor you should buy at least one quality 25 foot 3/8 inch air hose. Even for the portable compressors. It will ruin the motor to run one of these on a household extension cord. It is easier, cheaper and better for the compressor to take the air to the job not the whole machine.

If these are more than you need then I do have a “Best Budget 120 volt Home Air Compressor” list posted.
