You will be glad that you did! An air regulator is a device that lowers the downstream air pressure.

Downstream air is the air that’s moving from the regulator towards your request.

Compressed air will flow from the compressor reservoir into the air regulator ( this supply is sometimes known as upstream air ) and through a system of an internal diaphragm and springs, the regulator will maintain a continued downstream air pressure level, notwithstanding changes in the upstream supply pressure from the tank. If you can work out paths to do that, do make me aware, and we’ll both get rich! ,-) You’ll need to set the downstream air pressure from your regulator at a pressure level that’s's below the lowest air pressure that’ll be in-going from your air compressor. When the cut out pressure is reached, the compressor stops compressing air. When you start to use compressed air from the compressor tank, the pressure inside starts to drop, and at last the compressor will start again.

This is the ‘cut in’ pressure point. As a result, your claim, be it an air tool or an air brush, will ‘see’ varying pressures from the tank as the compressor cycles on and off between the two set points. Notwithstanding your best efforts with the air brush, if the supply air pressure is regularly changing, so too will the standard of your work. This brings us back to the why you can always have to have an air regulator installed in the line between the compressor and your device.

As the air compressor goes thru its standard cut-in and cut-out cycle your air regulator guarantees that your downstream device will see a steady, non-fluctuating, supply of compressed air. If your claim consumes more compressed air than your compressor can generate, though you have set your air regulator at a ‘safe’ level, ultimately the air pressure from the tank will fall below the level your regulator is set for, and the downstream device will see a continuously lessening air pressure supply too, this although your compressor could have cut-in, and is trying despairingly to build a supply of compressed air within the tank.
