DeVilbiss QM T-5 Series Service Bulletin

5, 10, 15 GALLON QMS TANKS
IMPORTANT: Read and follow all instruc-
tions and SAFETY PRECAUTIONS before
using this equipment. Retain for future
reference.
DESCRIPTION
DeVilbiss pressure feed tanks are intended
for use as a pressure container to supply
material at a constant preset pressure up to
a maximum of 110 psi. The tanks are built to
ASME specifications, and are FM approved.
DeVilbiss pressure tanks are also certified
for vacuum operation.
NOTE
These pressure tanks are constructed
from stainless steel and other non-
reactive materials. Materials con-
taining halogented solvents can be
used safely with these tanks.
Standard Nonregulated Tanks
(No Regulation)
Standard type tank for use to distribute
"regulated" air by remote filter/regulator or
other similar control to pressure tank.
Equipped with pressure gauge, safety valve,
air bleed down valve, and air inlet valve.
Standard Fluid Regulated Tanks
(Single Regulation)
Standard type tank for use on jobs where
precision control of both fluid and atomiza-
tion air pressures is not required. Also used
where atomization air can be taken from
filter/regulator air lines. Provides standard
fluid pressure control only. Equipped with
pressure regulator, pressure gauge, air bleed
down valve, safety valve, and inlet and
outlet air valves. (For conversion to double
regulation, use kit QMS-436.)
(STAINLESS STEEL)
Standard Air and Fluid Regulated Tanks
(Dual Regulation)
Precision controlled tanks for use with
materials that are best applied at low,
closely controlled, fluid and atomization air
pressures. Used with portable air compres-
sors or with air lines when no other means
of air pressure regulation (filter/regulator)
is available. Equipped with two regulators
(one for fluid pressure, the other for atomi-
zation air pressure), two pressure gauges,
air bleed down valve, safety valve, and
inlet and outlet valves.
Extra Sensitive Fluid Regulation
Tanks especially adapted for use with elec-
trostatic spray installations, application of
lubricants, special coatings, etc. Suitable for
use wherever extremely sensitive, non-fluc-
tuating low pressure control is required.
Large, reinforced, synthetic diaphragm
type regulator controls to a maximum of
30 pounds pressure. Equipped with extra
sensitive pressure regulator, pressure
gauge, air bleed down valve, safety valve,
inlet valve, and unregulated outlet valve.
Agitation
Pressure tanks can be equipped with differ-
ent types of fluid agitation, or no agitation.
Hand agitation or air agitators are provided
to suit any application.
Refer to specifications chart to ensure
that fluids and solvents being used
are chemically compatible with the
tank wetted parts. Before placing
fluids or solvents in tank, always
read accompanying manufacturer's
literature.
SERVICE BULLETIN
SB-21-064-J
Replaces SB-21-064-I
Air pressure loads that are higher
than design loads, or changes to the
pressure feed tank, can cause the
tank to rupture or explode.
• A safety valve protects the tank
from overpressurization. During
each use, pull ring on the safety
valve to make sure it operates freely
and relieves air pressure. If the valve
is stuck, does not operate freely, or
does not relieve air pressure, it must
be replaced with a safety valve
having the same rating. Do not
eliminate, make adjustments to, or
substitute this valve.
• Changes to the air tank will
weaken it. Never drill into, weld, or
change the tank in any way.
• Maximum working pressure of
this tank is 110 psi.
