In other words,
If Total Flow = 50%, Flow Air = 50%, then
Flow air = 1.7 bar (25 psi) or 1/2 of 3.4 bar (50 psi), and
Atomizing air = 1.7 bar (25 psi) or 1/2 of 3.4 bar (50 psi).
If Total Flow = 50%, Flow Air = 25%, then
Flow air = 0.86 bar (12.5) psi or 1/4 of 3.4 bar (50 psi), and
Atomizing air = 2.6 bar (37.5 psi) or 3/4 of 3.4 bar (50 psi).
NOTE: If either Total Flow or Flow Air % are set to 0% then the controller
will not output any air when triggered and no powder will be pumped.
Powder velocity is inversely related to transfer efficiency; the higher the
velocity the lower the transfer efficiency. High powder flow rates can result
in faster wear of powder contact parts.
Use this chart as a starting point making changes for powder volume or
delivery velocity as required. The data in this table was collected using 20
feet of 11mm ID powder tubing and a typical white epoxy powder. For
higher output use 12.7mm ID powder tubing. Powder output values in g/min
are typical, your results may vary.

Classic Flow Mode Settings
To use Classic Flow mode, the controller must be configured for it. Refer to
page 3-16 for a list of the mode defaults and configuration instructions.

sets the atomizing air pressure.
Setting values for both are 0−99% of maximum air pressure. Press the +
and − buttons to enter the desired setpoint. The longer a button is pressed
the faster the units change.
