Piston Compressor - This compressor is usually more powerful than a diaphragm compressor and produces more air than normally needed to propel an airbrush. Therefore, the air needs to be restricted before it reaches the air hose. The air regulator usually has an attached moisture filter which captures the moisture that is developed inside the compressor before it reaches the air hose. If the piston compressor uses oil, then an oil filter must also be attached after the regulator and before the hose to remove any oil that may work its way into the air source.

Propellant cans are an inexpensive substitute for a compressor.
A regulator is screwed onto the top of the can. In the center of the regulator is a brass screw that activates the propellant. Before attaching the regulator to the propellant can, make sure that the brass screw is totally unscrewed so you don't inadvertently activate the propellant while attaching the regulator. Once the regulator is attached, a vinyl hose is screwed onto the threads of the regulator. One end attaches to the regulator and the other end attaches to the airbrush.
