The single stage compressor would compress up to 20 CFM at the pressure of 125 psi, while a double stage would compress about 50 CFM at 175 psi.

Capacity and pressure

Two most important specifications while purchasing the air compressor are the pressure and the capacity. Just by adding the air consumption of all the air tools you can get the capacity required. The same would have to be done for pressure. It is always advised that you have some more capacity that that actually required by you.

Electrical connections

Before you go to buy the air compressor, check out the wiring at your workshop or garage. Know about the voltage of your home or work space and also the maximum current that can be handled by your wiring. Also you may require a 3 phase power, thus check about it too.

If you make an enclosure, do not forget to keep ventilation holes, so that the heat produced by the compressor is ventilated.

Tank size

You would find that most of the compressors come with a tank that ranges between 40-80 gallons. The larger the tank the better, as there would be bigger buffer for compressed air.

Duty cycle

Last, but definitely not least!

The percentage of time your compressor runs is its duty cycle. Generally the single stage have 50% duty cycle, that means after running the compressor for 5 minutes it need to cool down for another 5 minutes. However, the dual stage has 100% duty cycle and can run 24 hours a day.

Thus, before you buy a compressor, check these specifications and you would be benefitted.
