If you happen to be one working with air tools, say at home or at office picking the air compressor that's right for you can be quite some confusing. There is a good amount of information regarding air compressors available online. But it is even more important for you to understand how you can read the available information and select the perfect air compressor that can meet your needs. There is specific information that you ought to look for before you go out and fetch one air compressor.
The foremost point you should know about air compressors is that they are given ratings based on their CFM (cubic feet per minute) or LPM (liters per minute) output of the compressor for that tank pressure, pressure and horsepower.
If you want to own one compressor, the sensible way of purchasing is to first zero in on the tools that you will be using with the compressor. The air-powered tools have specific requirements of pressure and CFM which is the amount of air flow from the compressor needed to run the tools continuously. The rule of the thumb here is that the air compressor's CFM should exceed that of largest air tool by one and half times. Remember if you take a compressor which is appropriately sized, it will give service for long. In case you mull with the idea of running more air tools at one time with the same air compressor then you've got to take cumulative CFMs to run all of the respective tools which will be the minimum (read: minimum) amount of air flow the air compressor must and should meet.
There are some tools including impact tools or nailguns that use short gusts of compressed air and so these don't need high-powered air compressor. However, grinders, sandblasters and drills will call for continuous air flow and so require larger as well as high-powered air compressors. For this consider amount of air pressure that your tools require. The pressure means the quantity of air delivered from air compressor to the respective tool. Check the pressure ratings of the air compressor. Depending on the place it's manufactured, it'd be in PSI (pounds per square inch) or Bars (number of atmospheres).
In case you want to work with many tools at a time you don't have add the pressure requirements like we do for air flow, however, you need to know the pressure requirement for the biggest air tool and ensure your air compressor meets this pressure requirement.
Then you've got to take into account amount of air that will leak through the tools (in case your tools are aged). Buying a compressor with minimum amount of airflow needed, chances are that you will not get effective use of tools. It makes sense to buying the air compressor that gives a little more than minimum needed. But do not go overboard because you will have to fork out more for anything more. Take into account your budget too.
