1
Donaldson Company, Inc.
Improper operation of dust collectors and/or dust control systems may contribute to conditions in a work
area or facility which could result in severe personal injury, and product or property damage. All dust
collection equipment should be used only for its intended purpose and should be properly selected and sized
for its intended use.
Process owners have important responsibilities relating to identifying and addressing potential hazards in
their processes. When the potential for handling combustible dust exists within a process the process owner
should include combustion hazards in their risk management activities and should comply with applicable
codes and standards related to combustible dust.
Electrical installation must be performed by a qualified electrician.
This equipment is not designed to support site ducts, piping, or electrical services. All ducts, piping, or
electrical services must be adequately supported to prevent injury and/or property damage.
Site selection must account for wind, seismic zone, and other load conditions.
Equipment may reach peak sound pressure levels above 80 dB (A). Noise levels should be considered when
selecting collector location.
Combustible Dust Hazards
Among other considerations, the current NFPA standards require owners whose processes involve potentially
combustible materials to have a current Dust Hazard Analysis, which can serve as the foundation for their process
hazard mitigation strategy. Mitigation may include but is not limited to:
• Prevention of all ignition sources from entering any dust collection equipment.
• Selection and implementation of fire and explosion mitigation, suppression, and isolation strategies
appropriate for the risks in their process.
• Development and use of work practices to maintain safe operating conditions, and to ensure combustible dust
does not accumulate within their plant or process equipment.
Donaldson designs, manufactures, and sells industrial air filtration products for a wide variety of applications. Some
applications may include processes or materials with inherent fire and explosion hazards. Donaldson is neither an
expert nor a certified consultant in fire, spark, or explosion detection, suppression, or control. Donaldson does not
provide engineering consulting services related to process or dust hazard analyses, or code and standard compliance.
Complying with applicable codes and standards and managing the risks associated with the process or materials
remains the responsibility of the process owner/operator. Donaldson may provide referrals to consultants, suppliers
of equipment or services related to the detection and/or mitigation of sparks, fires and/or explosions, but Donaldson
does not assume responsibility for any such referrals, nor does Donaldson assume any liability for the fitness of a
mitigation strategy or product for a particular installation or application. The process owner’s final selection of dust
collectors and risk mitigation strategies should be based on the outcome of a Dust Hazard / Process Hazard Analysis
performed by the process owner. Although early engagement of a dust collector supplier provides helpful insights on
the availability and features of various products, process owners should consult with a combustible dust expert and/or
a process safety expert before making actual product and mitigation strategy selections.
Donaldson recommends that all industrial air filtration system designs be reviewed and approved by an expert
consultant who is responsible for the integrity of the system design and compliance with applicable codes and
standards. It is the process owner’s responsibility to understand the risks in their process and mitigate those risks in
accordance with all applicable laws, regulations and standards, including those published by the NFPA. Donaldson
also recommends that proper maintenance and housekeeping procedures and work practices be evaluated,
developed, and followed to maintain any industrial air filtration products in safe operating condition.
Many factors beyond the control of Donaldson can affect the use and performance of Donaldson products in a
particular application, including the conditions under which the product is used. Since these factors are uniquely
within the user’s knowledge and control, it is essential the user evaluate the Donaldson products to determine whether
the product is fit for the particular purpose and suitable for the user’s application. All products, product specifications,
and data (airflow, capacity, dimensions, or availability) are subject to change without notice, and may vary by region or
country.

Description
The Torit PowerCore CPV collector is a continuous duty
dust collector that uses obround style filter packs with
the proprietary axial flow PowerCore filter media. The
system is designed to provide optimum performance for
high efficiency, low operating pressure drop (energy
usage) within a small size collector. The filters can be
pulse-cleaned on- or off-line. Standard sizes range from
1 to 12 obround filter packs.
The Torit PowerCore CPV is not designed as a "stand
alone" collector. Rather, it is designed to be a filtration/
ventilation component of another component, such
as a silo or bin container. The open bottom of the
Torit PowerCore CPV is intended for roof mounting
applications. Some preparation work may be required
before installing the collector. An opening in the silo or
storage bin must have the correct dimensions and be
properly reinforced to support the weight of the Torit
PowerCore CPV. Reference the Rating and Specification
Information.
Purpose and Intended Use
Misuse or modification of
this equipment may result in
personal injury.
Do not misuse or modify.
Discuss the use and application of this equipment with a
Donaldson Torit representative.
In pneumatic conveying systems, Torit PowerCore CPV
can be mounted on the top of silos or storage vessels
to separate the product conveying from displaced air to
prevent product loss and nuisance dust. In mechanical
conveying systems, the dust generated by product
loading, transfer, and discharge can be controlled using
Torit PowerCore CPV on an enclosure. The collected
dust returns directly to the product conveyed making
expensive ductwork systems unnecessary, saving space,
and eliminating dust disposal issues.
Torit PowerCore CPV collectors can be integrated with
process machinery requiring dust control such as fluid
bed reactors, mixers, blenders, mills, and crushers. They
can also be used in bulk materials handling applications
and for bin venting. The CPV model is commonly used in
the grain, chemical, mineral, plastic, wood, composites,
paper, packaging, and textile industries.

Donaldson Company, Inc.
Operation
During normal operation, dust-laden air enters the
collector through the cabinet opening at the bottom of
the collector, which is fastened to the silo or storage
container. Airflow is directed upwards through the
collector. The CPV filter packs remove fine particulate
and clean, filtered air passes through the CPV filter pack
to the clean-air plenum and discharges through the
clean-air outlet.
Filter pack cleaning is completed using pulse-jet
technology. Air diaphragm valves provide the pulse
cleaning. An electronic solenoid valve actuates the pulse
cleaning. Filter packs are easily removed without tools
when they need to be changed.

The solid-state timer is used to control the filter cleaning
system. Available options include 3, 6, 10, 20, or 32-pin
solenoid valve controls.
1. Using the wiring diagram supplied, wire the
starter, solid-state timer and solenoid valves. Use
appropriate wire gauge for rated amp load as
specified by local codes.
2. Plug the program lug into the pin that corresponds
with the number of solenoid valves controlled.
3. With power supply ON, check the operation of the
timer and valves. The valves should open and close
sequentially at factory set 10-second intervals.
4. If a gauge or similar device is used to control the
solid-state timer, the jumper on the pressure switch
portion of the timer should be removed. The solenoid
valves will then pulse only when the differential
pressure reaches the high-pressure setpoint. The
valves will continue to pulse until the low-pressure
setpoint is reached.
The solid-state timer voltage
must match the voltage of the
rating of the timer provided (typically 120VAC).
Do not mount the solid-state timer directly
to the collector as mechanical vibration can
damage the timer.
Electrical installation, service
or maintenance work during

Solid-State Timer Installation
Solenoid Connection
The collector is equipped with electric solenoid valves
(typically 120V) that controls the pulse-cleaning valves,
which in turn clean the filters.
Solenoid enclosures are mounted near or on the
collector’s compressed-air manifold.
Wire the solenoids to the solid-state timer following the
wiring diagram supplied with the collector. Filter life and
cleaning operation will be affected if not wired correctly.
Timer and Solenoid Specifications
Power to the solid-state timer is supplied to Terminals
L1 and L2, which are intended to operate in parallel
with the fan starter’s low-voltage coil. On fan start-up,
power is supplied to the timer and the preset OFF time is
initiated. At the end of the OFF time, the timer energizes
the corresponding solenoid valve to provide the ON time
cleaning pulse for one diaphragm valve and then steps to
the next until all filters have been cleaned.
To pulse when the fan is OFF, install a toggle switch as
shown on the Solid-State Timer Wiring Diagram. When
the toggle switch is ON, the timer receives power and
energizes the solenoid valves’ pulse-cleaning operation
even though the fan is turned OFF.

Maintenance Information
Operational Checklist
1. Monitor the physical condition of the collector and
repair or replace any damaged components.
Routine inspections will minimize downtime and
maintain optimum system performance. This
is particularly important on continuous-duty
applications.
2. Periodically check the compressed air components
and replace compressed air filters.
Drain moisture following the manufacturer’s
instructions. With the compressed air supply ON,
check the cleaning valves, solenoid valves, and
tubing for leaks. Replace as necessary.
3. Monitor pressure drop across filters.
Abnormal changes in pressure drop may indicate a
change in operating conditions and possibly a fault
to be corrected. For example, prolonged lack of
compressed air will cause an excess build-up of dust
on the filters resulting in increased pressure drop.
Cleaning off-line with no airflow usually restores the
filters to normal pressure drop.
4. Monitor exhaust.
5. Monitor dust disposal.
Filter Removal and Installation
Use proper safety and protective
equipment when removing
contaminants and filters.
Dirty filters may be heavier than they appear.
Use care when removing filters to avoid

Electrical Connection (CPV-1 Only)
Electrical work must be
performed by a qualified
electrician and comply with all applicable
national and local codes.
Turn power off and lock out electrical
power sources before performing service or
maintenance work.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
1. Using the wiring diagram supplied, wire the
customer-supplied disconnect switch and fan starter.
Make the connections to the fan motor.
Use appropriate wire gauge for rated amp load as
specified by local codes.
2. Turn the fan motor On then OFF to check for proper
rotation by referencing the rotation arrow located on
the motor's mounting plate.
Do not look into fan outlet to
determine rotation. View the fan
rotation from the back of the motor.
Check that the exhaust plenum is free of tools
or debris before checking blower/fan rotation.
Stand clear of exhaust to avoid personal injury.
To reverse rotation, three-phase power supply: Turn
electrical power OFF at source and switch any two
leads on the output-side of the fan motor starter.
Do not interchange a power lead
with the ground wire. Severe
personal injury or equipment damage may
result.
Fan Blower (Except CPV-1)
Optional Equipment
Failure to lift the fan correctly
can result in severe personal
injury and/or property damage.
Use appropriate lifting equipment and adopt
all safety precautions needed for moving and
handling the fan.
A crane or forklift and qualified operator are
recommended for unloading, assembly, and
installation of the fan.
Location must be clear of all obstructions, such
as utility lines or roof overhang.
To avoid personal injury and/or damage to
equipment, ensure fan blowers are properly
attached to equipment.
The use of a damper or variable
fan drive (VFD) is required to
control airflow through the collector. Lack of a
control damper or VFD will shorten filter life.
The collector can accept direct mounted fan blowers,
Torit Backward Inclined (TBI) or Torit Radial Blade (TRB),
to the top or side of the collector.
For complete information, see the most current version
of the TBI or TRB Fan Installation, Operation and
Maintenance manual.
Fans are dynamically balanced and tested at operating
speeds to check for conformance to vibration limits. All
fans must be adequately supported for smooth operation

Magnehelic®Gauge
The Magnehelic is a differential pressure gauge used to
measure the pressure difference between the clean- and
dirty-air plenums and provides a visual display of filter
change requirements. The high-pressure tap is located in
the dirty-air plenum and the low-pressure tap is located
in the clean-air plenum.
1. Choose a convenient, accessible location on or near
the collector for mounting that provides the best
visual advantage.
If collector is equipped with factory-installed
pressure taps, skip to Step 5.
2. Before drilling, place a piece of non-combustible
cloth over the filter opening in the clean-air plenum
to protect them from drilling chips.
3. Place a piece of wood behind the drill location in the
dirty-air plenum to protect the filters from damage by
the drill bit.
4. Mount the pressure tap hardware on the clean-air
plenum panel and the dirty-air plenum.
5. Plug the pressure ports on the back of the gauge
using two, 1/8-in NPT pipe plugs supplied. Install
two, 1/8-in NPT male adapters supplied with the
gauge into the high- and low-pressure ports on the
side of the gauge.
6. Attach the mounting bracket using three, #6-32 x 1/4-
in screws supplied.
