performed in accordance with industry accepted practice and all relevant
local, state, and federal government codes, laws, and policies.
2SAFETY
2.1 Safety statement
The air cleaning equipment supplied by AAF International ranges from very
large multiple-component assemblies which require significant and complex,
rigging, handling and assembly on-site, to small compact assemblies that are
easily handled and maneuvered. In addition to size, many of the dust collectors
will require electrical connections, compressed air connections, and will feature
high speed rotating equipment.
At all times, when dealing with industrial equipment such as dust collection
equipment personnel safety must be the highest priority of all involved, from
riggers, installers, operators, users, and maintenance personnel. Those
responsible on-site shall review the details of the equipment beforehand and
develop a plan for dealing with all stages of the installation from receipt of the
equipment on-site to start-up, commissioning, and hand-over. All applicable
health, safety, and environmental (“HSE”) rules, regulations, and legislation shall
be fully complied with at all times.
2.2 Safe working practices and staff training
AAF International is fully committed to the safety of its employees and those
of its customers. In this spirit the following guidelines are offered for the
consideration of those responsible:

Filter Company, Inc., is prohibited. FabriPulse, AAF, REDClean,
REDFiltration, and Reliable Efficient Durable are registered
trademarks of American Air Filter Company, Inc. d/b/a AAF
International.
All personnel shall receive safety training specific to the site, the task, and
the conditions under which the work will be conducted.
All personnel shall be equipped with appropriate safety apparel and
equipment, such as clothing, footwear, hard-hats, gloves, ear protection, eye
protection, and safety harness.
All personnel involved in any stage of the process shall have been trained for
the tasks in which they will be involved and at all times shall be under the direct
supervision of experienced supervisors and managers.
All personnel shall be equipped with appropriate tools and equipment to
safely and efficiently complete their task.
Adequate lighting shall be supplied at all times while work is being
conducted.
A work perimeter shall be set up to define the limits of the area within which
the work will be conducted and outside which there will be no threat to the safety
of personnel or plant. The perimeter shall be taped-off and marked appropriately
to prevent accidental ingress of uninvolved personnel or equipment. When the
work area impedes into existing access ways or traffic routes for which no practical
alternative is available, barriers, wardens and flaggers shall be employed to safely
control crossing traffic and personnel.
At any time only those personnel directly involved in completing the task at
hand shall be allowed within the work perimeter.
2.3 Dust explosions
Dust explosions constitute a serious industrial hazard and may result in
death, serious injury, and/or devastating property damage. It is the responsibility
of the user to identify the nature of the dust and whether or not it poses an
explosive hazard and to properly mitigate this hazard. Except as otherwise
expressly provided in writing, AAF makes no representation or warranty in
connection with explosion hazard equipment, including, but not limited to, the
necessity or effectiveness of explosion hazard equipment or to the design,
installation, operation, and performance of such equipment. The basic standard for
dealing with explosive dust applications is the National Fire Protection Agency
(“NFPA”), NFPA 69: Standard on Explosion Prevention Systems. This standard

International.
applies to the design, installation, operation, maintenance, and testing of systems
for the prevention of explosions by means of various methods. The user shall be
fully conversant with the provisions of NFPA and shall comply in full with all of its
requirements.
By its very nature AAF equipment is intended to be used to capture airborne
particulate matter, otherwise known as dust. There are various methods for
dealing with a dust explosion in a dust collector. These can include, but are not
limited to, the use of properly designed explosion vents, explosion suppression
systems, or flameless vents. The user shall understand which method is being
used and who is responsible for the design and supply of the equipment required.
When an explosive dust has been properly identified to AAF the dust collector may
be structurally designed to withstand the internal pressure generated during the
explosive event and fitted with an explosion vent, or with multiple vents, designed
to safely discharge the pressure and the resulting fireball. The user shall review
the purchase order and the documents referenced within it to determine if
explosion protection equipment has been supplied by AAF International. Where
this is the case, review the appropriate sections of this manual that deal with the
installation, operation and maintenance of the equipment ordered.
When explosion protection systems are supplied by multiple vendors, it is
the responsibility of the user to coordinate between suppliers to ensure that the
equipment supplied by each vendor will work together to achieve the required
protection. For instance, if an explosion suppression system is being supplied by
parties other than AAF, it is incumbent on the user to ensure that the dust
collection equipment has been ordered to resist the internal pressure defined by
the suppression equipment supplier.
Dust collectors fitted with explosion vents must not be located indoors,
unless properly designed in accordance to NFPA regulations. The equipment shall
be oriented so that the vent will discharge to an unoccupied zone. Such a zone will
be prohibited to personnel and shall not include critical equipment or services such
as fuel storage tanks, flammable materials, fire hydrants, power distribution or
electrical control equipment, or similar. If the vent (or vents) is located on the
side(s) of the equipment the vent discharge area shall be isolated with barriers
erected to prevent the parking of vehicles, pedestrian use, use of the area for
temporary storage, etc. Warning signs shall be posted. Include diagrams showing
the distribution of a typical dust explosion discharge.

2.4 Electrical hazards
Before doing any work on the AAF equipment make sure that all potential
electrical hazards have been identified and that all electric current connected to
the equipment, and to any connected or associated equipment, has been properly
disconnected and securely locked-out to prevent accidental reconnection prior to
completion of the work. All electrical work shall be done in full accordance with the
current edition of NFPA 70, the National Electrical Code, and all other applicable
laws, rules, and regulations. All electrical work shall be performed by a licensed
electrician. Only original AAF parts shall be used as replacements for ongoing
maintenance and repair.
2.5 Rotating equipment
The FabriPulse M can include a fan which is installed on the top of the dust
collector, either on top of the collector or as an integral fan. The fan wheel rotates
at a nominal speed of 3,600 rpm and has the potential to cause severe injury. The
fan wheel could be accessed from inside the cabinet through the air inlet if the
pulse pipes are removed, and from outside the cabinet through the fan discharge.
All due care should be exercised to avoid any contact with the operating fan.
Under no circumstances should the fan ever be allowed to operate when any of the
access panels on the dust collector, or the silencer, have been removed. The fan
must be disconnected and locked out prior to the performance of any maintenance
work, see paragraph 2.4.
2.6 Safety guards
The dust collector cabinet prevents access to the fan inlet. All access panels
shall remain bolted in place while the fan is operating. Prior to the removal of any
access panels, the electrical power to the collector shall be disconnected and
locked out, see paragraphs 2.4 And 2.5. After electrical power is disconnected, the
fan wheel will continue to rotate for a period of time before coasting to a stop. Do
not access the fan until the fan wheel has come to a complete stop.
3GENERAL PRODUCT INFORMATION
3.1 Description
The FabriPulse M is a pre-assembled continuous and automatic self-cleaning
pulse-jet dust collector. The FabriPulse M is a complete pulse-jet collector system
capable of providing continuous on-line cleaning. This collector utilizes high
efficiency bag filter elements arranged in a vertical arrangement. Dust laden air
enters in the high inlet and moves in a true down flow direction between the
filters. The airstream passes through the media as the dust is collected on the

filter media. The clean air then moves through the tube sheet section and into a
clean air plenum at the top of the module.
There are three main designs of the FabriPulse M: standard hopper design,
bin vent design, and integral fan design.
The standard hopper design will have either a remote mounted or top
mounted fan, with a standard hopper.
The bin vent design will not have a hopper and does not come with a fan.
This is used to vent large areas, like a silo, by differential pressure between the
silo pressure and the atmosphere.
The integral fan design is the same design as the standard hopper design,
but with a fan that is integral to the top of collector.
3.2 Purpose and intended use
The FabriPulse M is intended to be used for relatively dry nuisance dusts,
with loadings generally less than 8 grains per cubic foot (8 gr/ft3). Typical
applications a FabriPulse M is used for include woodworking, metalworking,
chemical, mining, and food processing. The standard bag media that is used in the
FabriPulse M should be suitable for the intended application.
Contact AAF International for assistance on a bag design for your
application. It is recommended that you use only AAF International bags on AAF
International equipment.
3.3 Normal Operation
During normal operation, air enters the FabriPulse M dust collector through
the high inlet and moves downward through the dirty air plenum, in true “down
flow” fashion. The cleaned air passes through the filter elements, while dust is
collected on the outside surfaces of the elements. Clean air flows through the
center of the elements into the clean air plenum, where it exits through the clean
air outlet.
During filter element cleaning, a pulse controller automatically selects the
element or pair of elements to be cleaned, activating solenoid valves which open
air diaphragm valves. High pressure air pulses directly into the center of the
selected element, or pair of elements, for 100 milliseconds, blowing collected dust

off the filter element(s). The dust is swept downward into the hopper by the
prevailing airflow and gravity.
3.4 Sizes
The FabriPulse M comes with bags in two different lengths- 4 and 6 feet.
Each header of the FabriPulse M comes with 42 bags. The size nomenclature
for the FabriPulse M is the length of the bag, followed by the total number of bags,
followed by the total square feet of available media. For instance, the 6-336-1200
means that the collector has 6 foot bags, has 336 total bags, and a total media
area of 1200 square feet.
3.5 Filter elements
The FabriPulse M utilizes a unique header design that has a 6x7 array of
bags in each header. This makes maintenance of the collector much easier than
any other baghouse on the market. Each bag is 2.25” diameter bags and are
arranged in a 3”x2.5” spacing pattern. Bags are factory mounted over a
galvanized steel support spring and attached to a venturi.
Operating temperature is dependent on type of venturi and/or bag material
specified. Inspection, maintenance and bag replacement is through hinged, side-
mounted access doors. Contact AAF International for assistance on a bag design
for your application. It is recommended that you use only AAF International bags
on AAF International equipment.

Make certain that the housing is safely positioned onto the
hoppers/supporting steel structure and that it cannot possibly fall should there be
a failure of the lifting supports.
Secure the housing to the hopper with the bolts, washers, and nuts that are
supplied.
All the bolts must be tightened to the appropriate torque setting. The lifting
equipment can now be removed.
9.2.5 Installing the access components
When access components, such as an access platform, are ordered with the
FabriPulse M, separate installation instructions will be provided with the collector.
9.2.6 Installation of control panel
Refer to the electrical drawings issued with the GA drawing.
When the AAF Control Center or Pressure Demand controller is to be used,
select a location for fixing the enclosure within 15ft of the static taps located on
the FabriPulse M side panels. Usually the Pressure Demand controller is fixed to
the leg structure but it can be remotely located if desired.
AAF provides plastic tubing for the pulse controller to be located 15ft from
the static taps. A more remote position is acceptable if additional tubing is
obtained. A practical limit of 30ft applies.
Once the pulse controller is fixed in position, connect two parallel lines of
plastic tubing to the 2 connection taps on the pulse controller and the other ends
to the static taps located on the side wall of the FabriPulse M. These plastic pipes
allow the pulse controller to measure and display the differential pressure that
exists between the clean air plenum and dirty side plenum. In some modes of
operation, this differential pressure is used to control the pulsing.
Connect the high pressure port to the dirty side of the collector and connect
the low pressure port to the clean air side (back of the unit). Both ports are
located on the side of the collector.
See the separate pulse controller manual for a full explanation of its features
and modes of operation.

9.2.7 Installation of the filter elements
Check new header assemblies for bag or venture damage. The spring inside
the bag should stretch from the venture to the bottom of the bag. Also check for
venturis that may have become unseated during shipping.
Normally, when the bags need to be replaced, the entire 42 bag header is to
be replaced with a new one. An entire header can be replaced in minutes,
eliminating a labor intensive procedure of replacing 42 individual bags. Also, since
a new header is equipped with new sealing gaskets, reuse of old, worn and leaking
gaskets is also avoided.
For bag installation and removal refer to the image above and follow these
instructions:
1. Open the hinged door.
2. To remove the header, release the sealing levers by pushing them
toward the back of the collector. This will release the bag assembly for
removal.
3. Slide the bag assembly toward the door opening and remove. If the
unit has a second bag assembly behind the first, it may also be removed by
sliding it out the door opening.

4. The new headers are inserted by following the reverse procedure. Be
sure the headers are located against the interior stop before securing the
sealing lever.
5. Continue the above procedure for all bag assemblies.
6. IMPORTANT: Pull all lever arm handles outward until the lever arm
handle stops.
7. Close all access doors and tighten hand knobs to seal door. Lever arm
handles will be pushed in slightly by door, but will remain in “past center
locked” position.
8. Any bag assemblies that are removed and re-installed in the collector
shall be returned to its original place and orientation to ensure sealing.
There may be occasions when one or two bags become damaged and need
to be replaced. Individual bag replacement can be done with the following
instructions:
1. Unseat the venture/bag assembly, remove venture from expander
spring.
2. Push new bag/expander spring assembly up through the hole in the
tubesheet.
3. Snap the expander spring into the lower portion of the venturi
4. Slide venture down the bag
5. Continue sliding venturi/bag assembly down into the tubesheet hole
until the bag and grooved portion of the venturi contacts the tubesheet.
IMPORTANT: Top of the bag must be folded over the top of the tubesheet
so that the bag remains positioned between the top lip of the venture and the top
of the tubesheet. Leaks will occur if this is not accomplished.
6. Apply force to venture/bag assembly to seat it into the tubesheet. It
may be necessary to place a block of wood over the venturi and strike with a
hammer.
9.2.8 Installation of accessories
When accessories, such as sprinklers and airlocks, are ordered with the
FabriPulse M, separate installation instructions will be provided with the collector.
For complete information, see the most current installation drawing or separate
IOM.

9.2.9 Electrical connections
WARNING: Potential shock hazard. Disconnect power before servicing. Only
qualified electrical personnel should work on this system.
If the integral fan is purchased, the fan motor should be connected to the
power source through a fused disconnect, or combination motor starter with a
rating sufficient to protect the motor. Refer to the fan motor junction box for
proper wiring connections. Check the fan rotation against the rotation arrow for
correct motor connections. Fan rotation should always be clockwise when
looking down from the top of the motor. If incorrect, change the motor leads
as indicated on the motor wiring instructions. Provide adequate grounding of unit.
The FabriPulse M pulse-jet bag collector is supplied with electrical solenoids
in a NEMA 4 enclosure and the standard pulse controller in a NEMA4X enclosure.
Higher NEMA ratings are available as an option. Do not install in classified
hazardous locations without an enclosure suitably rated for the application and
location.
The standard pulse control supplied with the FabriPulse M is the DCT-1010
(or 1022) Dust Collector Timer Controller. This pulse controller is used for on-
demand or continuous cleaning applications.
To power up the DCT controller, connect power line to L1 and L2. Control
Wiring must be field installed between the solenoid valves and the pulse output
