Description
Torit Bin Vents (TBVs) apply cartridge technology
to a continuous-duty dust collection system,
offering significant advantages. They are designed
specifically for silo, storage bin and conveyor
transfer applications. Standard models include both
the Insertable-mounted cabinet and the Plenum-
mounted cabinet, with each available in three filter
configurations: a two (2) filter unit (TBV-2), a
four (4) filter unit (TBV-4) and a six (6) filter unit
(TBV-6). All standard TBVs include Donaldson
Torit® Ultra-Web® filters with continuous air
pulse-jet cleaning. This provides for a highly efficient
self-cleaning filtration system ensuring long filter life
and a reduced maintenance schedule. The TBV was
designed for simple filter service and maintenance
with a “tool-less” approach. The unit incorporates
top-side (clean air plenum) filter cartridge removal
and replacement, making it unnecessary to enter
the silo or storage container. No tools are needed
for the quick release pipe couplers when replacing
filters. This reduces the risk of contamination of
the customer product stored in the silo/storage
container.
The filter elements in the TBV are the key to
efficient, long life operation. With the high efficiency
filtration from this dust collector, exhaust air can
often be recirculated to the factory. To ensure high
efficiency operation, always use genuine Torit-Built®
replacement filter elements for your TBV.

Purpose and Intended Use
Misuse or modification of
this equipment may result in
personal injury.
Do not misuse or modify.
The Torit Bin Vent is used to vent displaced air
and contain valuable and/or harmful products
in bins or silos. As materials are conveyed to a
bin by various means (mechanical, gravity, and
pneumatic), air inside the enclosed bin is displaced.
The process by which excess air is removed is called
bin venting. The most common industries for the
TBV are food/agriculture such as grain and process/
manufacturing such as chemical/pharmaceutical,
cement, wood, foundries (clay, sand, additives), and
waste treatment. The most common dusts are lime,
cement, carbon, plastics, and wood.
Combustible materials such as buffing lint, paper, wood, metal dusts, weld fume, or
flammable coolants or solvents represent potential fire and/or explosion hazards. Use
special care when selecting, installing, and operating all dust, fume, or mist collection equipment
when such combustible materials may be present in order to protect workers and property from
serious injury or damage due to a fire and/or explosion.
Consult and comply with all National and Local Codes related to fire and/or explosion properties
of combustible materials when determining the location and operation of all dust, fume, or mist
collection equipment.
Standard Donaldson Torit equipment is not equipped with fire extinguishing or explosion protection
systems.

Unit Operation (Model TBV-4 shown)
Operation
During normal operation, contaminated or dust-
laden air enters the TBV through the cabinet opening
at the bottom of the unit, which is fastened to the
silo or storage container. The dust-laden incoming
air is collected on the outside surface of the filter
elements. As the dust cake collects on the outside
filter surface, gravity and air pulse-jet cleaning force
the dust to drop back into the storage bin. The
clean, filtered air flows up through the center of the
filter elements and passes through the venturi into
the clean air plenum, where it finally exits through
the clean air outlet. The clean air outlet can be
configured with a blower fan or a weather hood
side-mounted to the rear of the unit. Another option,
depending on the customer product being stored, is
to recirculate the clean air back into the work area
via duct work.
Filter Cleaning
The filter elements are cleaned automatically and
continuously during operation. Only a few filters
are off-line for pulse-jet cleaning at any given time.
A solid state timer controls the cycle of pulse-jet
cleaning. Solenoid-operated diaphragm valves open
in sequence, introducing jets of high pressure air into
venturis located above the filter element cartridges.
The resulting reverse airflow initiates the cleaning
cycle, which dislodges the dust accumulated on the
outside of the filter media, while the remaining filter
elements in the unit continue the filtration process.

*In general, Torit Bin Vents are shipped without
the blower/motor packs installed (shipped loose) to
better protect the equipment during transit. Filter
cartridges are shipped installed in the TBV plenum
models. In the TBV insertable models, the filter
cartridges are shipped loose to avoid crushing the
portion of the filters that extend below the bottom
of the cabinet.
Pre-Installation
The TBV is not designed as a “stand alone” unit.
Rather, it is designed to be a filtration/ventilation
component of a larger system, such as a silo or
bin container. The open bottom of the bin vent is
intended for roof mounting applications. Some
preparation work is required before installing the
unit. A hole must be cut into the silo or storage bin
to the correct dimensions.
Ensure the silo or storage bin is
reinforced to properly support
the weight of the TBV. Failure to do so
may result in a collapse causing personal
injury/and or property damage.
See the Specification Control Drawing for footprint
dimensions and weights.

Donaldson Company, Inc.

Filter Installation for TBV Insertable
The filter cartridges in the TBV insertable model
extend past the bottom of the cabinet when
installed. The filter cartridges would be crushed and
damaged under the weight of the collector if they
were shipped installed; therefore, they are shipped
loose and installed at the customer site once the unit
has been installed into a permanent location.
See the Filter Element
Installation section for plenum
models.
The TBV insertable-model must already be
installed in a permanent location before the
installation of the filter cartridges into the
unit.
1. Unpack the filter cartridges from each box,
which contains a filter element, a filter crank
rod, a rubber-backed washer and a steel
grounding tab.
2. Open the TBV top roof access door to its fully
open position (small notch on bar).
Failure to open the door
properly could result in
personal injury. Ensure the door is in the
correct open position.
Once the roof is secured, reach inside the clean
air plenum of the unit and disconnect the
blowpipes by pulling back the levers of the quick
release pipe couplers. Stow the blowpipes in an
upright position by inserting them into the slots
provided at the rear of the unit.
3. Reach down inside the clean air plenum of the
unit and halfway unscrew all the black hold-
down knobs. Reach down inside the venturi,
grasp the collar bracket and twist to the right
(clockwise) until the filter hold-down collar
clears all four screw studs. Pull up and remove
the filter hold-down collar assembly from the
clean air plenum.
4. Place the new filter element end-cap down
(gasket-side up). Slide the filter hold-down collar
down inside the open end of the filter element
until it stops. Lay the filter element on its side.

Solid-State Timer Installation
The standard control panel includes a solid-state
timer used to control the filter cleaning system.
Install the control box and customer-supplied fan
starter switch in a convenient location. Install
conduit and wire to the unit.
The solid-state timer requires
a 105 to 135-Volt customer-
supplied power supply. Failure to comply
may result in personal injury and/or
property damage.
1. Using the wiring diagram supplied, wire the
blower motor, blower-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 to 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.

Solenoid Connection
The unit is equipped with 115-Volt solenoid valves
that control the pulse-cleaning valves, which clean
the filters.
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 blower starter’s low-voltage coil. On blower
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 blower 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 blower is
turned OFF.
Input
105-135V/50-60Hz/1Ph
Output Solenoids
The load is carried and turned ON and OFF by
the 200 watt maximum-load-per-output solid-state
switch.
Pulse ON Time
Factory set at 100-milliseconds, or 1/10-second.
Do not adjust pulse ON
time unless the proper test
equipment is available. Too much or too
little ON time can cause shortened filter
life.
NOTICE
Pulse OFF Time
Factory set at 10-seconds, adjustable from 1 to
1.5-second minimum to maximum 60 to 66-second.
Operating Temperature Range
-20° F to 130° F
Transient Voltage Protection
50 kW transient volts for 20-millisecond duration
once every 20 seconds, 1% duty cycle.
Solenoid Valves
110 to 120-Volt AC coil with NEMA 4 rated DIN
socket rated at 15 watts includes a 1/2-in conduit
fitting. The solenoid valve is part of an integral
diaphragm valve assembly. DB-2000 is equipped
with 3/4-in solenoid valves and DB-3000 with 1-in
solenoid valves.
Compressed-Air
Set compressed-air supply at 90-psig. The timer is
factory set to clean one filter or set of filters every
10-seconds.
Do not set compressed-air
pressure above 100-psig.
Component damage will occur.
NOTICE

Donaldson Company, Inc.

cleaning valve failure or poor collector
performance.
Purge compressed-air lines to remove debris
before connecting to the unit’s compressed-
air manifold.
1. Remove the 1-in pipe cap from unit’s air
manifold and connect the compressed-air supply
line. Use thread-sealing tape or pipe sealant on
all compressed-air connections.
2. Install a customer-supplied shut-off valve, bleed-
type regulator with gauge, filter, and automatic
condensate valve in the compressed-air supply
line.

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.
The pressure taps for this gauge are factory installed.
For units being installed in remote locations, such
as on top of silos and storage containers, it is
recommended to mount the gauge at ground level
adjacent to the control box and motor start switch.
1. Choose a convenient, accessible location on or
near the unit for mounting that provides the best
visual advantage.
If unit 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 the filters 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. Mount the pressure tap with
the tee inside 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. Attach the
mounting bracket using three, #6-32 x 1/4-in
screws supplied.
6. Mount the gauge and bracket assembly to the
supporting structure using two self-drilling
screws.
7. 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.
8. Carefully remove the cloth protecting the filters.
Close access doors and tighten securely by hand.

2. Check for and remove all loose items in or near
the inlet and outlet of the unit.
3. Check that all remote controls are wired into the
control system and all service switches are in the
OFF position.
4. Check that all optional accessories are installed
properly and secured.
5. Check that hopper discharge is open and the
storage container is sealed, if equipped.
6. Turn power ON at source.
7. Turn the compressed-air supply ON. Adjust
pressure regulator for 90-psi.
8. 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 through 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, single-phase power supply:
Follow manufacturer’s instructions on the
motor’s nameplate.
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.
9. Adjust the blower/fan for proper airflow by
adjusting the volume control damper on the
blower/fan discharge, if equipped.
Excess airflow can shorten
filter life, cause electrical
system failure, and blower motor failure.
