Common Terminologies for Air Compressors

If you’re going to have to work closely with Air Compressors, one of the things you have to keep in mind would have to a set of terminologies that you would be encountering. If you’re a frequent visitor of, then all the more you would have to be familiar, as these terminologies are usually determined by the parts used. These terms that you use for Air Compressors are not that many, and are mere acronyms of the actual terms. Having said that, below are the different air compressor terms which you would have to be familiar with.


PSI is known as Pounds per Square Inch. This is the English system measurement for pressure, and the different types of pneumatic tools are in need of its own respective PSI rating. Different tools have different standard PSIs, with a nailer having 90, a single-stage compressor having 135 PSI.


A measurement of power which is common in other applications as well is the Horsepower. This would most definitely apply to the motor. Depending on the design or the size of the compressor at hand, it could range everywhere from 1.5 HP to 500 HP. The higher the HP, the more flexible it would be.


If you’re on the lookout for a compressor, one of the most crucial details you would have to know would be the CFM rating, or the cubic feet per minute. This is because through this particular compressor property, you are able to effectively determine the number of tools that you may use at a given time. The higher the CFM, the wider the range of tools you can use. The tools that greatly require a high CFM include sanders, grinders, and other materials which are in need of smooth and continuous operations.
