You often hear people suggest, "Turn up the pressure, you'll get more air." The truth is just the opposite. You will get more pressure, but less air.
There is a law in physics, called Boyles Law, that states: "For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional." What this means is that as one doubles, the other halves. You can't have both. So unless you have to have 150-175 psi for an application, turn down the pressure. You'll get more usable air and your compressor will last longer.
