MATERIALS OF CONSTRUCTION
Zinc plated carbon steel tank, lid, fluid tube,
lid bushing and outlet elbow fitting. Agitator
shaft (agitated models); molded nylon pro-
peller (agitated models); polyethylene liner.
PT-418 AIR MOTOR DRIVEN AGITATOR
The agitator utilizes an air driven motor to
turn the agitator shaft to which a propeller
is attached. The rotation of the propeller
mixes materials which have a tendency to
separate or settle quickly. Material agitation
may be performed at the same time mate-
rial is being sprayed without any adverse
effect. The air motor is powerful and smooth
running. An air adjusting valve is included
to control the speed of the agitator. The
air motor requires low air consumption,
approximately 3-6 C.F.M. at 60 P.S.l. (Max.
input air pressure 100 P.S.l.)
INSTALLATION
Mix and prepare material to be used accord-
ing to manufacturer’s instructions. Strain
material through a fine mesh screen (60
or 90 mesh) to remove all foreign matter
which is likely to enter and clog material
passages.
1. AIways relieve all air pressure in the
tank. Turn thumbscrew on air pressure
relief valve. Wait until pressure bleeds
down.
2. Loosen thumb screws, tip lid clamps
back and remove lid assembly.
3. Pour material into the tank. See ac-
cessories for strainers and disposable
tank liners. A one gallon container
may also be used by cutting 3/16" off
end of fluid tube at an angle.
4. Replace the lid assembly and tighten
clamps and thumb screws securely.
5. If possible, the air supply line should
pass through an air filter/regulator
to filter dirt from air and remove en-
trained water and oil. See Accessories
for filters available. Connect the air
supply hose to the air inlet fitting on
tank regulator.
6. Connect the atomization air hose to
the air outlet fitting which is directly
opposite air inlet fitting.
7. Connect material hose to the fluid outlet
fitting.
8. See Figure 1 for a typical hookup.
Figure 1
OPERATION
1. Turn on the air supply.
2. Turn T-Handle adjusting screw clock-
wise on the tank regulator to increase
material pressure: turn it counter clock-
wise to decrease pressure. Maximum
tank pressure is 80 PSI.
3. For tank with air motor agitator, turn
the knob of the air adjusting valve (8)
counterclockwise to set the desired
agitator speed. Operate the agitator at
the minimum speed required to keep
the material thoroughly mixed. Do not
over-agitate the material. Air bubbles
may form in the material, causing a
poor finish.
4. Atomization air for the spray gun can be
adjusted at the gun by means of an air
adjusting valve or, with the additional
air regulator provided with “dual regula-
tion” tank models (83C-220 or 83C-221).
5. See Spray Gun instructions for opera-
tion of the gun.
If using an air quick disconnect
(Q.D.) at the inlet to the regulator
at the pressure tank, do not discon-
nect the Q.D. while the tank is pres-
surized. Doing so will allow tank
pressure to quickly relieve, and can
potentially pull paint back through
the air regulator and air motor,
depending upon the liquid level
in the tank. Tank pressure should
always be relieved by turning the
regulator fully counterclockwise
or turning thumb screw on air
relief valve.
REPLACEMENT OF PARTS
(Air Motor Assembly, See Page 5)
Do not pry front plate (40) or end plate (46)
from air motor body (43) with a screwdriver;
this will dent the surface of the plates and
body causing leaks. A puller tool should be
used to remove the plate from the motor
body while maintaining the position of the
shaft. Holes must be drilled for dowel pins
(42) after assembling front plate (40) on new
body (43) for alignment of parts. Always
install new end plate gaskets (41) when
reassembling air motor.
