I have this regulator on a Porter-Cable compressor and liked it so well that I bought another one to replace a unit on another older compressor that I use for airbrushing. It works perfectly. Some regulators, while they allow you to set the airflow at a given pressure, allow the pressure to build in the line when the flow is stopped (trigger of the airbrush is released). When you then press the trigger the initial blast of air is at a higher pressure than what is set for the continuous airflow. Not with this regulator. It maintains that pressure constantly so there is never a build-up when the airbrush is static. Every time you depress the airbrush trigger you get the same airflow that you've set. Don't forget to use the sealant tape when installing it.
