An airbrush compressor is a necessary part of the airbrush system. These miniature compressors are a version of the larger counterparts, look very much the same, except in a smaller size. It’s probably a good idea to “oversize” your airbrush compressors a little bit. What this means is that even though the airbrush compressors unit flows 15 CFM at 60 PSI, you will only need perhaps 3 CFM at 20 PSI. You can achieve this pressure through the use of a pressure regulator. This way, you can adjust the airbrush compressors pressure either higher or lower depending on your needs at the moment. Having the higher capacity compressor will enable you to be able to use heavier paints without any problems or issues arising.
Other things you should take into consideration when making you purchase of an airbrush compressors:
Noise levels – lower cost airbrush compressors, and indeed some of the higher priced ones too, are noisy. The cost of getting rid of the noise however, can come at a price.
Oil-less Compressors: Almost a must have. Who wants oil marring the surface of an otherwise fantastic piece of artwork?
Water: You’ll want to make sure the system is equipped with a filter to keep water off your work, which is just as destructive as oil.
A regulator is necessary for your airbrush compressors to control the CFM and PSI levels. This is true of any compressor.
Duty Cycle: You will want to know this too. Not all compressors are suited for continuous duty.
The bottom line to selecting the proper compressor is to be sure that you end up with a unit with ample flow, ample pressure both for now and as your business grows. Buy a unit with a little more capacity now, or you may end up making a second purchase for a more productive airbrush compressor unit in the near future. Remember to maintain the compressor unit properly, and to drain the liquid from the receiver on a regular basis, and your unit will serve you well for years to come!
