For heavy production spraying, air pressure for atomiza-

tion is controlled by the regulator on the air source. The

fluid pressure is regulated by a separate fluid regulator

at the bulk paint source.

This popular method is similar to the siphon feed with cup

except that the paint cup is mounted above the spray gun.

This creates a positive fluid pressure in the fluid nozzle while

providing better balance and comfort for the operator.

stt; this will avoid the possibility of cross threading the

parts. If the parts can not be turned by hand easily, make sure you have the correct

parts, unscrew by hand easily, make sure you have the correct parts, unscrew,

realign, and try again. NEVER use undue force in mating parts.

1) Connect the paint cup to the fluid inlet nipple and tighten to ensure a good seal, 

using spanner. Use of the supplied filter screen is optional. This filter helps protect 

against small particle contaminants. See parts drawing for proper filter placement.

2) Wrap the threads on the air inlet nipples of 

the spray gun and the regulator with a 

couple of layers of PTFE tape to help 

prevent air leaks. 

3) Connect the regulator to the air inlet nipple 

at the base of the gun handle. 

4) Connect the air supply to the air inlet 

nipple on the regulator.

In order to qualify as an HVLP spray gun, dynamic air pressure, when measured at

the air cap, must not exceed 10 PSI. HVLP Spray guns produce a soft, low velocity

spray pattern which provides increased control while reducing paint “bounce-back”

and overspray. As a result, HVLP is also well suited for spraying surfaces with

recessed areas.

Air pressure for atomization is controlled by the regulator

on the air source. The amount of fluid is adjusted by the

fluid control knob on the gun, the paint viscosity, and the

air pressure. The siphon cup must be vented to the

atmosphere.

Air pressure for atomization is controlled by the regu-

lator on the air source. The fluid pressure is set by

adjusting the cup regulator. The amount of fluid is also

adjusted by the fluid control knob. This method is

required for heavy fluids and when using internal mix

nozzle spraying. This method generally requires a spe-

cial fluid tip, needle and air cap set.

This method is similar to the pressure feed cup hookup

with the added benefit of being able to orient the gun in

any position independent of the tank. This method is

useful for medium production or large scale spraying

applications where large quantities of paint are used.

For medium production spraying (single regulator setup

on tank), air pressure for atomization is controlled by

the regulator at the air source. The amount of fluid is

adjusted by the regulator on the paint pressure tank.

For portable painting operations (double regulator setup

on tank), air pressure for atomization and fluid supply is

regulated by two individual air regulators on the paint

pressure tank.
