NOTE: Values are based on actual test data, however, they should be considered approximate due to
variations in air supply source, volume and pressure. Data was obtained with a ¾” pipe supply
line source connected to a standard ½” pressure regulator with pressure gauge. Larger sizes (5/8”
and ¾”) cannot be determined because of air volumes.
