Factors to consider when choosing your compressor:

• Type—Wheeled Portable, Hand Carry Portable, Stationary

• Volume of Air-cubic feet per minute, (CFM), and pounds per square inch, (PSI), of pressure required

• Electric or Gas engine driven

Here are some helpful descriptions of various terms to help you choose the proper compressor.

CFM - cubic feet per minute It can be noted as CFM displacement or CFM delivered air. Delivered air is what runs your tool or provides adequate air to perform your job. CFM displacement is merely the bore X stroke X rpm. CFM delivered air is the vital rating. It is the CFM displacement X the efficiency of the compressor. This rating varies widely depending on the quality, design,manufacturing tolerances of the compressor pump, and the final air pressure being produced.

PSI—pounds per square inch This is the pressure of the flow of air. As pressure increases, the volume of air, (CFM), decreases. Therefore, it is easier to produce higher CFM at lower pressures. Your application may require a specific PSI, but volume (CFM) runs your tool.

Delivered Air - Don't be fooled by incomplete ratings. Air pressure alone does not drive your fastener, or operate your sander, air wrench, or paint gun. You need CFM delivered air at a given pressure. While a unit rated by CFM displacement only or even by CFM delivered air at a lower pressure may appear to be larger, it may be inadequate for your needs.

Horsepower - You're not driving a car. Air runs your tools, not horsepower. Efficient air compressors consistently produce greater volumes of delivered air. This makes you more efficient. This saves you money. Horsepower can be noted many different ways. The motor or engine horsepower rating should not be a deciding factor in your choice of compressor.

Tank Size - The Tank stores reserve air. It doesn't help the compressor make more air. A large air receiver can't help you if your pump is inefficient or too small. You'll run out of air when the stored air has been used.
