General Specifications
The Dual Internal Air Head Assembly is a heavy duty wet only industrial vacuum. It will pick up wet and moist waste
without the need to change any filters. This compressed air vacuum has no moving parts and has tremendous suction
for a portable unit. It is designed to fit onto a 55-gallon rolled top steel drum (Tornado # 95942) for volume pick-up with
maximum efficiency. All recovered products go into the drum, therefore maintaining peak performance. The included
liquid shut off attachments prevent over filling of the drum. Use for volume pickup of light to medium oils, liquid sludge,
and many other light to medium viscosity liquids. Designed to perform at maximum efficiency with 2” hoses and attach-
ments (refer to attachments section of this manual).

When using this unit, basic precautions should always be followed. Read all instructions before
using this unit.
Do not leave machine unattended when running. Turn off when not in use.
Before attempting any maintenance or adjustment, disconnect air lines.
Do not expose to rain.
Do not allow to be used as a toy. Close attention is necessary when used by or near children.
Use only as described in this manual. Use only manufacturer’s recommended attachments.
If machine is not working as it should, has been dropped, damaged, left outdoors, or dropped into water, return it to a
service center.
Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.
Turn off all controls before disconnecting air lines.
Do not put any object into openings. Do not use with any opening blocked. Keep openings free of dust, lint, hair, and
anything that may reduce air flow.
Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes.
Do not pick up flammable or combustible liquids, such as gasolline, or use machine where they may be present.
Do not use without filters in place.
Use extra care when cleaning on stairs.
Always replace worn or torn external filters immediately. This will prevent possible injury due to flying objects.
Never operate with intake unguarded. Strong suction will pull fingers and/or clothing into hose and other parts.
Always wear safety glasses when in vicinity of this unit.
Never operate above 100 p.s.i. (8 BAR) pressure.
Always turn off your air line supply at the drop before disconnecting the air line.

ASSEMBLY OF HEAD UNIT AND DRUM
1. Remove all components from package.
2. The Venturi Powerhead(s) come already attached to
the Jumbo Covers. To detach, remove the double
unit air connector, then turn powerhead(s) counter-
clockwise and they will unlock from the Jumbo
Cover.
3. Install hose adaptor onto Jumbo Housing. Lock in
place by lining up adaptor indent with lock screw
and tightening lock screw.
4. Place head unit onto drum (required accessory). The
weight and suction power of the head unit will form a
seal on the drum.
OPERATING RULES
Use 1.5” to 2” I.D. hoses and attachments.
Use 3/4” air line hose and flow-thru quick connects (do
not use ball style fittings).
90 p.s.i. (7 BAR) at gauge (valve open) for maximum
pickup power, 60 p.s.i. (5 BAR) at gauge (valve open)
for lighter debris recovery.
Use to recover water, heavy oils and oil soaked metal
shavings.
IMPORTANT: The internal air vacuums do not have inter-
nal filters for dry recovery. They are assembled with
silencers built inside the venturi powerhead and are
designed for wet application only.
Breuer Tornado does offer an optional internal filter kit
that will convert this unit to a dry and moist pickup vac-
uum. Please note that if this conversion is done, it will be
considered a dry/moist pickup vacuum only, and cannot
be used for any wet/liquid pickup of any kind. Contact
Breuer Tornado for more information on this conversion
kit.
Head Assembly Setup and Operation
STARTING/STOPPING MACHINE
1. Connect air supply line to head line connector.
2. Start vacuum by turning air valve located on line
connector to its ON position.
3. Stop vacuum by turning air valve located on line
connector to its OFF position.
NOTE: Empty and clean vacuum and attachments after
each days use for maximum performance.

1. Machine does not operate Make sure air line valve is in ON position.
Inspect air regulators for interference of air flow.
Inspect air compressor for adequate size, and verify that
proper air pressure is available (60 to 90 p.s.i.)
Inspect air line for proper size and/or damage.
Always use flow thru connectors.
2. Machine stops running Inspect drum level.
Inspect air line for damage.
Inspect air pressure.
3. Machine has no suction Inspect for clogged hose, collapsed hose, defective drum,
material too heavy for unit.
4. Air pressure drops at gauge Inspect air compressor for proper free air consumption and
resistance in air line size or connections.
5. Machine has poor recovery Inspect for correct size hose and attachments, poor sealing,
defective drum, material too heavy for unit.
Inspect for proper drum cover seal (gasket).
Inspect for damage and/or wear to hose and accessories.
Inspect locked position(s) of venturi powerhead(s) to jumbo
cover.
Inspect all seals for wear and/or damage.

COMPRESSED AIR VACUUM FACTS
1. Use the smallest air jet possible to do the job. The
smaller the jet, the lower the compressed air C.F.M.
required.
2. Use a single venturi unit where liquid recovery is the
primary application. A single venturi will recover liquids
as fast as a double venturi will, yet consumes only one
half as much compressed air.
3. Use a double venturi or quad venturi unit where higher
volume of vacuum air is required. Remember, com-
pressor overload is more likely to occur with a quad
than a double venturi.
4. Use the lowest air line pressure possible per the given
jet size to do the job. The lower the line pressure, the
lower the compressed air consumption.
5. Air line must be maintained at the valve of the venturi
unit. If pressure is not maintained at the unit, vacuum
performance will not be reached. Be sure to use
low line pressure for light liquid recovery, and high
line pressure for liquids, sludge, and other heavy
debris.
6. The air line hose should be as short as possible, and of
maximum inside diameter (single 1/2”, double 3/4”,
quad 1” recommended). Line air losses that occur are
related to hose length and diameter, thus reducing
performance.
7. Any air line moisture (condensation) should be elimin-
ated. Using a water trap in the air line to the venturi unit
will help maintain peak performance.
8. Air line components can reduce performance. Quick
disconnect couplings and line filters, for example, may
reduce compressed air delivery.
9. Factors that affect compressed air supply are com-
pressor horsepower rating, compressor C.F.M. rating,
and system resistance of installed air lines.
Things To Know
AIR COMPRESSOR EVALUATION
Independent of high horsepower or high compressor
C.F.M. rating claims made by individuals, the final evalua-
tion in determining if a compressor is capable of supply-
ing enough compressed air, is to demonstrate the air
vacuum with a pressure gauge at the venturi unit. This
will show the actual pressure being maintained while the
unit is operating (refer to fact #5). This approach will also
compensate for air line system resistance losses. If the
compressor cannot maintain the free air consumption
necessary, the line pressure will drop. Consequently, the
compressed air C.F.M. will also drop, thus reducing the
vacuum or suction performance.
NOTE: The compressed air C.F.M. is not the same as the
vacuum air C.F.M.
