Now that you know the most common activities for which an air compressor is used, let’s talk about the types of compressors. In the market, there is a range of models and brands to choose from. However, it is essential to emphasize that it is necessary to know what the purpose of the air compressor will be to start your search. Some models meet the simplest to the most complex need. To choose the right one, you must research the product’s model, brand, and guarantee. After all, if your need is more complex, it is essential to find an air compressor with a good origin.
PSI – Air Pressure
When researching your air compressor from Fluid-Aire Dynamics for example, you will notice the acronym PSI, which means air pressure, on the technical sheet. The vast majority of equipment needs 90 PSI to function correctly. So be aware of that.
Thus, the product description will show how much air pressure the compressor has. Also, air compressors have two stages. The first stage has up to 90 PSI, while in the second stage, the equipment can have up to 175 PSI.
A vital tip: Before using your air compressor, check that nothing is restricting its air hose. If you have something blocking the air passage, it can make it difficult for the air pressure to reach the proper capacity.
HP – Power
The power of the air compressor from Compressed Air Installation Contractor for example is one of the things you need to be more aware of when buying. The power is the compressor’s force, which will define how vital the equipment is.
The common power rating of an air compressor is 1.5 and 6.5 HP. Air compressors with higher HP capacity are those reserved for industrial use, which, in addition to higher HP, also offer higher PSI. If your goal is a compressor for low-complexity use, you don’t need to look for one with power as high as those for industrial use.
CFM – Cubic Feet per Minute
The CFM is what measures the volume of air an air compressor produces. Thus, CFM appears in different ratings at various pressures of a compressor. You might notice a high displacement CFM rating, for example. This is a classification based on the size and speed of the air compressor pump. However, it is unimportant since it is at zero pressure and does not consider pump inefficiencies.
The most essential CFM on smaller compressors is 90 PSI, which is the pressure required to operate most equipment. It’s essential to be aware that CFM ratings tend to be slightly exaggerated.
So, to choose correctly, consider that you should have 3 – 4 CFM per actual HP at 90 PSI.
