Performance figures stated in this manual are based on a standard atmosphere of 59°F
(15°C) at 29.92” Hg (1,014 millibars) at sea level, using 60 Hz power. Altitude is an
important consideration when specifying vacuum conveying components. AEC can
advise you on proper selection and sizing of systems for your operating environment.
AEC is committed to a continuing program of product improvement.
Specifications, appearance, and dimensions described in this manual
are subject to change without notice.

Safety Considerations
AEC VacTrac conveying systems are designed to provide safe and
reliable operation when installed and operated within design
specifications and national and local safety codes.
To avoid possible personnel injury or equipment damage when
installing or operating this equipment, always use good judgment
and follow these safe practices:
; Follow all SAFETY CODES.
; Wear SAFETY GLASSES and WORK GLOVES.
; Use care when LOADING, UNLOADING, RIGGING, or
MOVING this equipment.
; OPEN, TAG, and LOCK ALL DISCONNECTS before
working on equipment. You should remove the fuses and carry
them with you.
; GROUND your VacTrac system properly before applying
power.
; Use extreme caution when working with your VacTrac system.
HIGH VACUUM can be dangerous. Keep body parts, tools,
clothing, and debris away from vacuum inlets.
; Do not jump or bypass any electrical safety control.
; Do not restore power until you remove all tools, test
equipment, etc.
; Only fully trained personnel familiar with the warnings and
instructions in this manual should work on this equipment.

1General Information
1-1Equipment Function
AEC VacTrac Series conveying systems create vacuum for
conveying pelletized, granular, or powder material in a central
material handling system.
A typical use is as an in-plant distribution system for plastic
processing plants.
1-2Necessary Documents
The documents listed below are necessary for proper installation,
operation and maintenance of VacTrac conveying systems. You
can obtain additional copies from the Service Department at AEC,
Inc.
Make sure that appropriate personnel get familiar with these documents:
• This product manual
• The VacTrac Series controller product manual
• Electrical schematic and connection diagrams
• The PLC manual
• Blower and electric motor information sheets
• Operation and Installation manuals for installed options and
accessories
1-3System Capabilities
VacTrac Series central vacuum systems are as varied as the
applications that they service. Tubing and equipment furnished in
an AEC -designed system is intended to convey the material(s)
specified at the time of purchase at specific rates and distances.
Mechanical ComponentsWH2-605A.4
VacTrac™ Series Conveying SystemsPage 9
AEC can advise you on your system capabilities based on system
makeup, distance, material, and desired conveying rates.
Pressure drops in the overall system directly affect system
capacity, such as number of material line bends, footage of
pipe, Y-tubes, T-tubes, etc.
The less distance, flexible hose, and bends you use on material
lines, the better. Keep material lines as straight as possible.
Vacuum leaks occurring anywhere in your system reduce capacity.
1-4Equipment Cycle
VacTrac Series material conveying systems are used for automatic
pneumatic handling of most free-flowing, dry, pelletized, powder
granular materials.
Important!
Material characteristics determine the type of equipment needed to
properly convey the material.
See Figures 18 and 19 on Page 46 for typical system
configurations.
Basic System Components
A typical VacTrac Series conveying system contains the following
components:
• Vacuum receiver(s)
• VacTrac vacuum pump
• Filter chamber
• Sequence or atmospheric valves
• Controller
• Take-off compartments
Page 10VacTrac™ Series Conveying Systems
WH2-605A.4Mechanical Components
• Pickup tubes/wands
• Vacuum and material tubing
Combinations of these components help you build your VacTrac
system for the application you need.
Basic System Types
VacTrac Time-Fill Systems
A VacTrac time-fill system conveys material to an on-line vacuum
receiver for a pre-set time period. When this interval elapses, the
controller conveys material to the next on-line vacuum receiver.
VacTrac Volume-Fill Systems
A VacTrac volume-fill system conveys material to an on-line
vacuum receiver until the material level activates the proximity
switch in the vacuum receiver, or a preset time elapses. When
either of these conditions occur, the controller conveys material to
the next on-line vacuum receiver.
Basic Operation
When you activate the controller, the system energizes and initiates
the conveying cycle. The following components energize:
• The vacuum pump motor starter.
• The vacuum pump vent valve.
• The sequencing valve above the first on-line vacuum receiver
that requires material.
The vacuum pump draws vacuum to that receiver. When the
receiver is full or the time interval elapses, the controller then
signals the atmospheric valve above the next on-line receiver
requiring material to energize, allowing material to convey to that
receiver. The conveying sequence continues to the last on-line
vacuum receiver requiring material.
When the time interval for the last receiverelapses or the receiver
is full, a new conveying cycle begins at the first on-line vacuum
receiver requiring material.
