How much air pressure do I need for my application

There are many areas to consider during the selection process of an air compressor for your business. Most important, determining the proper size of the compressor to match your operational needs. Then secondly, making sure you have the correct installation to adequately support the compressor. The goal, purchasing a compressor sized large enough to have an ample supply of air without overloading the compressor. 

Keep in mind, your operational requirements could have various minimum supply air pressure needs. It is important to take the highest rating of the minimum pressures needed and what application the air compressor will be used for. Figuring out your cubic feet per minute (CFM) of air and pounds per square inch (PSI) for the operational demands of your facility will assist in helping you align with the right compressor. For example, if you will be using it to power air tools, then you need to determine the CFM of each tool and typical frequency of use.

Good news , Ash Air can help to make it easy to figure out the CFM and PSI to align you with the correct compressor. If you need help deciding which size is best for you, please contact us for any assistance.

If you're wondering what an air compressor actually is, you've come to the right place. Simply, air compressors convert power in to air that is pressurised which is then used to power air tools such as spray guns. Air compressors are used in a wide range of applications, so naturally if you want one that will be designed for spray painting your vehicle, you want a compressor specifically made for spray guns! This way your compressor will be able to provide the right amount of power to perform the job.
