Setup

6. Adjust the Spray Pattern

WARNING

COMPONENT RUPTURE HAZARD

Do not exceed the 100 psi (0.7 MPa,

7 bar) maximum fluid and air pres-

sure of this gun. Higher pressures can cause parts

to rupture and result in serious injury.

Follow these steps to establish the correct fluid flow

and air flow:

A. Adjust the fluid flow using the fluid pressure

regulator (L) installed in the gun fluid line. Typical

industrial flow rates will vary with regulator pres-

sures from 5 to 30 psi (34 to 210 kPa, 0.3 to

2.1 bar).

NOTE: A larger fluid nozzle at a reduced fluid pressure

will maintain the same flow rate, but slow down the

fluid stream (velocity). When air is applied, this allows

the air to act on the fluid longer and improve the atom-

ization.

B. Using the air pressure regulator (F), set the fan

and atomizing air supply pressure at about 50 psi

(345 kPa, 3.4 bar). On manifolds 241696 and

241697, the fan and atomization air must be sup-

plied and regulated separately. On manifold

243950, one air line supplies both atomization and

fan air. Adjust the pattern length and shape by al-

tering fan air pressure (or adjusting the fan adjust-

ment valve on manifold 243950). Refer to the

Pressure Drop Chart on page 11 for the regulator

setting vs gun inlet pressure.

If available, use the fluid manufacturer’s recom-

mendations to set the air line pressure for high vol-

ume, low pressure, spray gun application.

NOTE: Local laws may limit the maximum pres-

sure to 10 psi (70 kPa, 0.7 bar) at the air cap for

HVLP compliance. 43 psi (300 kPa, 3.0 bar) inlet

air yields 10 psi (70 kPa, 0.7 bar) at the air cap.
