Types of Airbrush Compressors
There are four basic types of airbrush compressors. The main differences in the compressors have to do with price and size. If the compressor will only be used occasionally for hobbies or sporadic projects, a portable, inexpensive model may be the best choice. If the machine will be used every day for business or shop applications, a larger, sturdier, more expensive model would be a better investment.

Diaphragm Airbrush Compressors
-
Diaphragm airbrush compressors appeal to many hobbyists and people who like to tinker with home projects. It is highly portable, small, dependable and comparatively inexpensive. The diaphragm airbrush compressor has a pressure limit of 30 pounds per square inch, so it cannot handle large jobs. The compressor has a diaphragm that oscillates through vacuum power. This motion drives air in one direction through a valve.
The main complaint about the diaphragm airbrush compressor is that the valve often vibrates as air passes through it, making fine lines and details impossible to create. Other drawbacks include its noisy operation and excessive heat generation. Guidelines for this model often urge users to limit usage to 20 minutes per session to prevent overheating.
Silent Airbrush Compressors
-
Although these models operate with almost no noise because the motor is surrounded by oil, they are heavy and cumbersome to transport. Many styles have a dolly-like base to make mobility easier. This airbrush compressor is highly reliable and requires minimal maintenance. Its relatively high price is its main drawback.

Oil-Less Airbrush Compressors
-
Generally regarded as the mid-priced favorite, oil-less airbrush compressors lack the desirable high pressure of the silent models. They are also a bit easier to transport than the silent kind. On the downside, oil-less airbrush compressors are a bit noisy. Some models also experience overheating problems.
Industrial Airbrush Compressor
-
Another moderately priced unit, the industrial airbrush compressor also uses no oil. It is large, bulky and hard to operate indoors. This compressor is known for being the loudest airbrush compressor of the group, which also detracts from its popularity. On the plus side, it can also be adapted for various other tools that require compressed air.
Choosing Wisely
-
No matter what airbrush compressor model you choose, the main consideration should be that the air pressure and flow are constant and controllable enough to complete jobs to your satisfaction. Price is important, as is product value. Make sure the noise level of the unit is acceptable to all who are within earshot of the project site.
