vs. Bleeder Gun
Optional Air Inlet
HVLP guns differ from conventional air spray guns in two main areas:
One difference is the size of the internal air ports. Conventional gun air

port openings are approximately
openings
those in conventional guns. Keep in mind that HVLP atomizes with a high
volume of air and low pressure.
The second major difference is the manner in which the material is moved
from the cup out of the nozzle. HVLP units pressurize the cup, forcing
material to the nozzle. A conventional gun creates a vacuum to siphon
material to and through the nozzle.
The term non-bleeder means that when the user releases the trigger of the gun,
the air flow stops. With a two-stage trigger, the user will first feel air coming
f rom the air cap; trigger further and material flow will begin. With a bleeder
gun, air flows continuously; the trigger only starts and stops the paint flow.
The Maxum II Gun offers two air inlet locations: one on the bottom of the
handle for non-bleeder set up and the second directly behind the air control
valve. To set up the gun in bleeder spray mode, remove the air control knob
and replace it with the air inlet fitting from the bottom of the gun. Close the
air inlet fitting with the plug supplied with the gun. The air hose can now be
attached to the gun. When using this location, the gun becomes a bleeder gun
by always discharg i n g air. This location is particularly helpful spraying inside
lockers or cabinets.
Another area to utilize the top air inlet is to improve atomization with very
heavy materials. This can be done by bypassing the air valve so air is directly
channeled to the air cap.
