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.
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.

Operation
During normal operation, dust-laden air enters the
unit through the cabinet opening at the bottom of the
unit, 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 an electronic timer used to
control the filter cleaning system. Available options
include 3, 6, 10, 20, and 32-pin solenoid valve control.
1. Using the supplied wiring diagram, wire the fan
motor, fan-motor 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
solenoid valves. The valves should open and close
sequentially at factory set 10-second intervals.
4. If a Photohelic gauge or similar device is used to
control the solid-state timer and the jumper on the
pressure switch portion of the timer is removed,
the solenoid valves pulse only when the differential
pressure reaches the high-pressure setpoint. The
valves 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 115VAC).
Do not mount the solid-state timer directly to
the unit. Mechanical vibration can damage the
control.
Solenoid Connection
The unit is equipped with 115-V solenoid valves that
control the pulse-cleaning valves, which clean the filters.
One of three types of solenoid enclosures, the
weatherproof NEMA 4 with 3D2 solenoids, the explosion
proof NEMA 7 with 5D2 solenoids, or the explosion proof
NEMA 9 with 5D2 solenoids, is mounted near or on the
unit’s compressed-air manifold.
Wire the solenoids to the solid-state timer following
the wiring diagram supplied with the unit. 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 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.

Side-Mount Power Pack
Electrical service or maintenance
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.
Mounting a power pack on the
side of a collector requires a
power pack adapter to support the weight of
the power pack.
Poorly installed power packs may separate
from the collector resulting in personal injury
and damage to equipment or property.
1. Disconnect power supply.
2. Apply 1/4-in diameter rope-type sealant to the
outside surface of the power pack adapter between
the fan mount bolt holes and the round fan inlet hole.
3. Install the fan housing to the power pack adapter
using 3/8 x 1 1/4-in bolts, flat washers, and hex nuts.
Install bolts with the bolt head in
the fan housing and the threaded
end in the power pack adapter.
4. Reinstall the motor, bracket, and fan wheel assembly.
Align motor mount bracket to the mark on the
housing on 30 Hp/60 Hz and 20-30 Hp/50 Hz units.
Other motor sizes do not require alignment, but
consider the electrical connection location.
5. Connect power supply to the motor. Turn the fan
motor ON then OFF to check motor rotation by
referencing the rotation arrow on the blower.
To change rotation on three
phase units, turn power supply
OFF and switch any two leads on the output
side of the fan motor starter.
NOTICE
NOTICE
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.

Donaldson Company, Inc.
Magnehelic®Gauge
The Magnehelic is a differential pressure gauge used
to measure the pressure difference between the clean-
air 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 unit for mounting that provides the best visual
advantage.
2. 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.
3. Attach the mounting bracket using three, #6-32 x 1/4-
in screws supplied.
4. Mount the gauge and bracket assembly to the
supporting structure using two, self-drilling screws.
5. Thirty-five feet of plastic tubing is supplied and must
be cut in two sections. Connect one section of tubing
from the gauge’s high-pressure port to the pressure
fitting located in the dirty-air plenum. Connect
remaining tubing from the gauge’s low-pressure
port to the fitting in the clean-air plenum. Additional
tubing can be ordered from your representative.
6. Zero and maintain the gauge as directed in the
manufacturer’s Operating and Maintenance
Instructions provided.
