DeVilbiss SB-21-058-H Manual

IMPORTANT: Read and follow all instruc-
tions and SAFETY PRECAUTIONS before
using this equipment. Retain for future ref-
erence.
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. DeVilbiss pressure
tanks are also certified for vacuum opera-
tion.
Halogenated hydarbon solvents -
for example: 1, 1,
trichloroethane and methylene
chloride - can chemically react
with aluminum parts and compo-
nents and cause an explosion haz-
ard. These solvents will also cor-
rode the galvanized tank coating.
Read the label or data sheet for
the material. Do not use materi-
als containing these solvents with
these pressure tanks. Stainless
steel tank models may be used
with halogenated solvents.
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 tanks for use on jobs where
precision control of both fluid and atomiza-
tion air pressures is not required. Also used
2 GALLON QMG TANKS
(GALVANIZED)
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 regula-
tion, use kit QMS-436.)
STANDARD AIR AND FLUID REGULATED
TANKS
(Dual Regulation)
Precision controlled tanks for use with mate-
rials that are best applied at low, closely
controlled, fluid and atomization air pres-
sures. Used with portable air compressors or
with air lines when no other means of air
pressure regulation is available. Equipped
with two regulators (one for fluid pressure,
the other for atomization 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 electro-
static spray installations, application of lubri-
cants, special coatings, etc. Suitable for use
wherever extremely sensitive, non-fluctuat-
ing low pressure control is required. Large,
reinforced, synthetic diaphragm type regula-
tor controls to a maximum of 30 pounds
pressure. Equipped with extra sensitive pres-
sure 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
accompanying manufacturer's
literature.
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 substitutions to 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.
