CONVEYING
Conair’s DustBeater vacuum material loaders provide flexibility
in meeting the varying demands of conveying pelletized and regrind materials to a hopper, bin or processing machine.
The DB8 is ideal for lower-volume conveying up to 200 lbs/hr.
The DB12 provides a larger loader body, filter and vacuum
motor for higher-volume conveying, up to 1000 lbs/hr.

Conair’s DustBeater series, the most
reliable loader line, is now even better
with the new Easy Loading Control
(ELC) and improved options to meet
your demanding material transfer
needs. The unit provides powerful conveying, is easy to set-up and simple to
maintain. The latest generation offers
an optional brushless motor for long
motor life with no brush maintenance
(DB12).
The optional ControlMate pendant allows you to load regrind along with virgin material, purge the conveying line,
adjust blowback pulses and load and
hold. Built-in security levels allow easy
parameter viewing of simple day-today settings, yet secure the critical settings.
A choice of loader configuration allows
direct loading to machine throats or
hopper loading to bins and hoppers.

SELF-CONTAINED VACUUM LOADERS
DUSTBEATER DB8 AND DB12 MODELS
HOW IT WORKS
A signal from the loader’s demand switch indicates to the ELC-M on
the loader that it requires material to be conveyed to satisfy its demand. The ELC-M sends a signal to the vacuum motor on the loader
to energize and start a loading cycle. The material is then drawn in
by the loader’s vacuum motor. If the hopper is filled, the demand
switch will remain open (Fig. 1) and no further load cycles will be
needed. However, if the demand was not satisfied and the demand
switch closes (Fig. 2) the loader will continue with loading cycles
until the demand is satisfied.
Loading Control
The ELC-M displays a loader’s sequence within its
conveying cycle with icons and associated LEDs.
The control has precise, reliable electronics
for operation, programming and alarms.

ELC ControlMateTM
Pendant
The ControlMate pendant
consists of eight LEDs, a
three-digit numeric display
and three push buttons.
The ControlMate comes with
an ethernet cable that supplies power and communications to the pendant from the
main ELC control.
ControlMate User Level 1 Parameters
• On/Off
• Unload Time
• Load Attempts
• Ratio Layers
• Ratio Percentage
• Purge Time
• Load Time
• Blowback
• Interchangeable programming - One optional pendant can be
used to control all ELC controls within your system.The ControlMate
pendant can be used with either the ELC-M or ELC-16.
• Change up to 16 parameters - Eight standard control parameters
are accessible through User Level 1. An additional eight parameters
are accessed through User Level 2. These additional parameters
activate loading options such as: priority demand, fill sensor logic,
demand sensor logic, fill sensor present, load and hold, purge/
Adjustable Purge Valve (APV) installed, ratio installed, blow
back installed.
• Easy-to-read display - Both the ControlMate pendant and the ELC
control use icons and associated LEDs to symbolize various loading
parameters.
DISCHARGE VALVE CONFIGURATION
The gravity discharge valve uses a
non-contact, magnetic reed switch
to signal loader demand. Stand-offs
provide a rugged guard to prevent
discharge damage. The huge opening eliminates material bridging.
A positive discharge air-operated
discharge valve is also available.
DIRECT FEED CONFIGURATION
Mount directly to a machine throat
with a direct feed glass hopper
(3 sizes available). An air-tight seal
at the throat is required, or an isolator valve may be included. Quickdisconnect clamps allow
easy loader removal for
thorough cleaning. A simple
grate magnet may also be
included in the cast base for
catching tramp metal.

TUBING CONNECTIONS
DustBeaters are built for a lifetime of service,
so common wear components are designed
for easy replacement. Tubing stubs are
threaded and may be easily replaced in the
event of damage, extreme wear or even for
changing line sizes.
EASY LOADING CONTROL (ELC)
Individually mounted Easy Loading Controls
(ELC) operate the loader’s vacuum pump when
it receives a signal from the demand switch to
start a conveying cycle.
EASY FILTER CLEAN/CHANGE
The lid may be easily removed from the loader
with no tools. The reinforced dacron disc filter
simply drops into place. All connections are
quick-disconnect for fast maintenance and
easy service.
OPTIONS
A Broad Choice of Options Stretch the Value of your DustBeater Purchase
Brushless Motor
Wear Plates
No maintenance. Longer life. Higher throughput. These new
motors incorporate technology that transforms the incoming
power into fast acting magnetic pulses that interact with the
motor armature to create rotation faster than ever possible
with traditional brush architecture. Provides near-frictionless
motor performance, similar to, but far exceeding the performance of traditional three-phase motors.
(DB12 only).
T-1 tool steel plates, installed inside the loader body, radically
reduce hopper wear when conveying highly abrasive materials like glass-filled compounds. Wear plates may be easily
replaced, if needed.
Sound Shield
The sound shield option bolts into place
easily with no loader modification. This is
a very effective option for both the new
brushless as well as traditional brush motors.
Magnets
An airtight, Drawer Magnet may be added below any direct
feed DustBeater to trap ferrous metal. Or, a low cost Grate
Magnet may be inserted directly into the glass hopper of the
direct feed receiver to save head room.
Stainless Steel Material Contact
Provides stainless steel in place of carbon steel. The 304 grade
stainless steel is uncoated internally (in material contact
areas), but powder coated externally for optimum cosmetic appearance.
Volume Fill Sensor
Provides automatic shut-off of the loader's vacuum sequence
when the loader is full. An alarm message is displayed on the
control if not satisfied during the vacuum sequence.
Ratio Valve
Dual inlet, single outlet material valve allows the loading of a second material
(usually regrind) in approximate, layered
percentages along with virgin material.
May be installed on loader inlet or remotely.
See the Ratio Valve specification sheet for more information.
Remote Demand Sensor
To trigger the operation of the loader (demand) from a location
other than directly below the loader, a remote demand sensor
may be used. Useful on oversized drying hoppers to sense
through a window (6 foot cable provided) or when off-loading
a granulator (30 foot cable provided). Extension cables are
also available.
Positive Discharge Valve
Provides a pneumatically driven discharge valve on the bottom of the loader in the event that gravity will not sufficiently
open the standard flapper after loading. Useful for very light
materials or when high CFM drying hoppers are being loaded.
(DB12 only).
