Safe operation and good practice use of your BK-75 dust collection
system April 2001
The BK-75 dust collection system is designed to accept one dust inlet. Dust is drawn into the BK-75 by
its onboard air suction system. The air stream and dust is passed through a filter bank where a significant
amount of the dust is removed from the air stream. The air is then ducted out of the BK-75. The following
minimum safe practices should be read, understood, and practiced by all users of the BK-75, and those
persons who maintain the BK-75, or are present in the BK-
To minimize fire, explosion, health and other risks to personnel and property:
Do not use your BK-75 to collect materials prone to explosion unless it has been specifically
modified to be “explosion proof”.
Do not draw debris from different alloys into the BK-75 system.
Do not use water or other electrically conductive fluid in your BK-75 unless it has been
specifically modified for wet operation.
Do not mix wood, plastic, paper, or other flammable material debris with metal or other
high temperature dust/debris.
Do use a spark-arresting device if your BK-75 will be used to collect debris from materials
that spark or otherwise create ignition level debris when worked.
Do consult with the appropriate authorities to be certain that your BK-75 installation and
its intended use comply with local, state, and federal codes.
Do use approved inhalation protective devices in conjunction with the BK-75.
Do use approved protective eye, face, hand, and body protection when grinding, polishing,
or otherwise creating dust and debris that you intend the BK-75 collect.
Do disconnect all power to the BK-75 (and any equipment connected to it) prior to
performing adjustments, maintenance, or other activity that involves opening any cover on
the BK-75.
Do read, understand, and abide by the operating and maintenance instructions provided for
the BK-75.

Caution!
Application of Dust Control Equipment
• Combustible materials such as buffing lint, paper, wood, aluminum or steel dust, weld
fume, or flammable solvents represent fire or explosion hazards. Use special care when
selecting and operating all dust or fume collection equipment when combustible
materials are present to protect workers and property from damage due to fire and/or
explosion. Consult and comply with National and Local Codes relating to fire or
explosion and all other appropriate codes when determining the location and operation
of dust or fume collection equipment.
• When combustible materials are present, consult with an installer of fire extinguishing
systems familiar with these types of fire hazards and local fire codes for
recommendations and installation of fire extinguishing and explosion protection
systems. Donaldson dust collection equipment is not equipped with fire extinguishing
or explosion protection systems.
• DO NOT allow sparks, cigarettes or other burning objects to enter the hood or duct of
any dust or fume control equipment as these may initiate a fire or explosion.
• For optimum collector performance, use only Donaldson replacement parts.
Warning – Improper operation of a dust control system may contribute to conditions in the
work area or facility that could result in severe personal injury and product or property
damage. Check that all collection equipment is properly selected and sized for the intended use.

Description
Purpose and Intended Use
Cabinet Series 50 to 80 dust collectors are selfcontained, intermittent-duty collectors with
envelope-style filters. Using the EZ Filter Pack™
filter system, Cabinet series collectors provide
highly efficient, low maintenance air cleaning.
Filters are cleaned using the standard manual filter
shaker or an optional motorized filter shaker which
cleans the filters automatically each time the unit is
turned off. The EZ Filter Pack is designed for quick,
easy filter replacement without the use of special
tools.
Designed to increase the versatility of the unit,
standard options include a hopper package for a
5-gallon pail or 55-gallon drum, indoor and
outdoor exhaust deflectors, HEPA filter packs, and
exhaust silencers. Four filter media choices and
three construction options are among the many
options available to customize the unit to the
specific application.
Caution!
• Misuse or modification of this
equipment may result in personal injury.
• Do not misuse or modify.
Cabinet collectors provide excellent efficiency on
nuisance dust generated in industrial operations
and are a good choice for low airflow, light-load
applications that do not require continuous airflow.
Typical applications include grinding, buffing and
polishing, abrasive blasting, batch mixing, and bag
dumping. Often, individual Cabinet collectors are
dedicated to one or two machines.
Four filter media selections offer a wide variety of
characteristics: cotton sateen is the standard media
and provides good efficiency in applications up to
180° F; polyester sateen provides the same
efficiency, but has higher temperature resistance
(240° F) and is more abrasion-resistant; woven
polyester provides better dust release capabilities
with lower efficiency; and polypropylene provides
some chemical resistance up to 180° F.
Standard galvanized construction includes
galvanized metal support bars, slide latches, bag
clips, and hardware to support most applications.
Optional stainless-steel construction is tailored to
corrosive environments. This option includes
stainless steel clips and screws if the screws
protrude into the dirty-air chamber. Slide latches,
support bars, and other hardware located in the
clean-air chamber remain galvanized steel.
Grounded, non-spark construction includes the
standard frame and polyester sateen filter media,
an additional stainless steel wire-mesh insert,
stainless-steel bag clips, and ground wires.

Operation
During normal operation, dust-laden air enters the
unit through the dirty-air inlet and passes through
the unit where the dust collects on the outside
surface of the filter media. As dust collects on the
filter surfaces, a dust cake forms, which actually
improves the efficiency of the filters. The greater
the amount of dust cake accumulated, the higher
the efficiency of the filter.
The filtered air flows up through the center of the
filters and into the clean-air chamber. Clean,

Pushing down on the hand- or foot-operated shaker
pedal and releasing rapidly six times completes
manual filter cleaning. The releasing action causes
the dust cake to fracture and fall into the dust
storage area. Motorized filter shakers are optional
and automatically clean the filters each time the
unit is turned off.

The automatic shaker is driven by a 1/10 Hp
TENV gear motor controlled by a solid-state timer.
The timer control box can be ordered with or
without step-down transformers. A timer control
box without the transformer requires a 120-Volt
AC power supply controlled by a customer-supplied
fan starter. Input power is supplied to the timer on
fan motor shutdown, through the normally-closed
auxiliary contact of the fan starter. After a 60second delay, the timer energizes and the shaker
motor starts for a 30-second fixed time. Turning the
unit ON and OFF initiates the shaker sequence.
Wiring
1. Mount the timer control box in a convenient,
accessible location on or near the unit.
2. Complete the wiring to the fan starter, timer,
and shaker motor according to the appropriate
wiring diagram.

Solid-State Timer Specifications
Sequence of Operation
Input power is supplied to Terminals L1 and
L2 of the automatic shaker control. On fan
shutdown the normally-closed auxiliary
contact closes and power is supplied to the
solid-state timer which activates the delayon-make timer. After 60-seconds, the delayon-make timer energizes the interval timer
and starts the shaker motor. After 30-sec,
the interval timer times out and the shaker
motor turns OFF.

Preliminary Start-Up Check
Start-Up
1. Check all electrical connections for tightness
and contact.
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. Excess
airflow to the blower will cause electrical
failure.
6. Turn power ON at source.
7. Turn the fan motor ON then OFF to check for
proper rotation by referencing the rotation
arrow located on the motor’s mounting plate.
To reverse rotation, single-phase power supply:
Follow manufacturer’s instructions on the
motor’s nameplate.
1. Turn power ON at source.
2. Turn unit ON.
3. On hopper models with 5- or 55-gallon drum
storage, check that hopper discharge is open
and the storage container is sealed, if equipped.
Excess airflow to the blower will cause
electrical failure.
4. When airflow diminishes, turn the unit OFF and
manually shake the EZ Filter Pack.
To reverse rotation, three-phase power supply:
Turn electrical power OFF at source and switch
any two leads on the output-side of the fanmotor starter.
