This is suitable for simple applications, nailing and sawing as well as light work.

 

Two Stage Air Compressors 

These types of air compressors have 2 cylinders.  They operate by moving air from the cooling tube into another cylinder at 90 PSI and then into the tank at 175 PSI.

When analysing air compressors,  the CFM rating is of out most importance.

CFM stands for Cubic Feet per Minute.  This indicates the amount of air coming out of the air compressor.

It’s important to note that the CFM rating of any air compressor is different at different pressure or PSI levels. However, most 20-gallon air compressors offer a CFM rating of 5 or higher.

Maximum Air Pressure
