Having a gauge for your airbrush setup is a must. Metallics need a bit higher pressure while regular thinned paint colors require a lower setting. This is where this gauge is great to have on your compressor.

The same reason as the other filters & regulator with a gauge, You need one on a large compressor or a tank.

I love this gauge and filter. I place it right next to the airbrush so I can always easily adjust the pressure and look for debris. Slightly on the larger side and the threading does not allow for adjustment of the direction it points but once you get accustomed to its presence it is a part of the airbrush I won't do without.
