Air Compressor Modification Tutorial

There are a number of cheap hobby compressors out there that are tankless and this means that the motor needs to keep running in order to supply the airbrush with air. This quick "tutorial" is basically a quick guide in how to install your own tank on your compressor. 

The tank will allow your compressor not not have to run continuously and hopefully preserve its life span. I will also discuss other potential modifications that may be helpful.

Of course the first thing you need is a compressor and an air tank. Be sure to purchase a tank and air hose that can handle the working pressure you intend. Since airbrushing usually requires very little PSI, this most likely will not be a problem.

I attached my tank at a "T". If necessary, I can put a valve on the T-branch to be able to isolate the tank. (potential benefits discussed later)

My tank is a little bit small. I would recommend 3-5 gallon tanks for this particular application. This keep your compressor from restarting repeatedly.

I used a type of fitting known as "push to connect" fittings. This allows for easy removal and transportation as I can disconnect the tank and move tank and compressor seperately.

Other Ideas:

For people that do pressure resin recasting, the pressure pot can be used as an air tank. By use of the "T" fitting and adding the valve mentioned above, the compressor can be used for airbrushing and other purposes even while you are casting.

It might be beneficial to add a regulator on the airbrush "branch" of the T fitting. This will allow for quicker pressure changes when you need them and will allow you to store more air in the tank as it will not affect the working pressure of the brush.

That's all! Any comments, questions, corrections or suggestions are appreciated.
