Atomizing Air Pressure
bar (psi)
25 25 1.7 (25) 1.7 (25)
40 10 2.7 (40) 0.689 (10)
In other words,
If Flow air = 25%, Atomizing air = 25%, then
Flow air = 1.7 bar (25 psi), Atomizing air = 1.7 bar (25 psi).
If Flow air = 40%, Atomizing = 10%, then
Flow air = 2.7 bar (40 psi), Atomizing air = 0.689 bar (10 psi).
Refer to your pump manual for typical operating values for Flow and
Atomizing air.
