AIR FLOW (scfm)
GUN
AIR INLET PRESSURE (psi)
Atomizing Pressure Versus
Activator Inlet Pressure
Air
flowing through the gun creates back pressure,
which the activator must overcome before beginning to
flow
. The chart below shows the minimum activator
pressure required to overcome the atomizing air
pressure. Higher pressures may be necessary to
maintain the mix ratio.
