1INTRODUCTION
This document contains the information necessary to properly receive,
assemble, install, operate, and maintain the AAF®ArrestAll®filter system and
filters. The purchaser, installer, and operator of the filter system MUST read and
comply with this document in its entirety prior to installation of the equipment and
its operation. Failure to comply with the requirements of this manual may void the
product warranty. The information and guidelines contained in this manual are not
exhaustive, and additional or different precautions, measures, training, etc. may
be needed depending on the specific circumstances.
CAUTION
These instructions are specific to the AAF ArrestAll filter system and filters.
All ancillary tasks including, but not limited to, electrical and mechanical
work, equipment handling, and safety procedures must be 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:

this document contains, without permission of American Air Filter
Company, Inc., is prohibited. ArrestAll, 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 from the National Fire Protection Agency
(“FPA”), NFPA 69: Standard on Explosion Prevention Systems. This standard
applies to the design, installation, operation, maintenance, and testing of systems

Filter Company, Inc. d/b/a AAF International.
for the prevention of explosions by means of various methods. The user shall be
fully conversant with the provisions of NFPA 69 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(s) 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, or use of the area for temporary
storage. 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 ArrestAll 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 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 ArrestAll self-contained dust collector is a compact and efficient unit
designed to control intermittent, low to medium volume, dry, dust sources. It is
cleaned off-line, meaning that it cleans once the fan is turn off. The unit includes
an air mover and can be relocated as required.
Each collector is furnished with fan assembly, housing, filter cartridge(s),
and an automatic shaker mechanism for filter cleaning. Based on size, they are

available as a bin vent, flat bottom, cart bottom, and funnel bottom arrangements.
The size range is from 1,000 to 12,000 ACFM.
3.2 Purpose and intended use
The ArrestAll is intended for intermittent dust collection and is best suited for
dry free flowing dusts. Examples of such applications would be woodworking
shops, small sanding booths, cement, clay, etc. It is not intended for dust
collection that is continuous, heavy dust loads, or for small particulate.
3.3 Normal Operation
Dust laden air is drawn into the inlet where it turns vertically 90 degrees,
causing the heavier particles to fall into the collection container below. The fine
particles are drawn to the fabric pockets and trapped on the surface, forming a
dust cake which increases efficiency. The clean air flows from the pockets into the
fan and is discharged. The collected dust is periodically removed from the fabric
pockets by an automatic shaker system.
3.4 Sizes
There are 12 unique ArrestAll sizes, ranging from an AR1-3 through an AR6-
25. The first number in the name designation is the number of filters in the unit,
the second number is the fan horsepower. This means an AR4-20 has 4 filters and
a 20HP fan.
The standard funnel bottom design is available on all unit sizes, as is the bin
vent design. The Dust Drawer design is only available on the AR1-3 as a standard
design. The Dust Cart is only available on the AR1-3 through the AR3-15L as a
standard design.
The following page is the fan performance curve for each size unit. Contact
AAF International for assistance in sizing the right ArrestAll for your application.

3.5 Filter elements
The ArrestAll filter has been designed to maximize airflow and efficiency. The
pocket and separator geometry minimizes differential pressure (see Figure 1). The
one-piece construction adds strength and sealing integrity to achieve up to 99+%
efficiency on general industrial dust by weight.
Figure 1. ArrestAll filter design
The ArrestAll filter design minimizes internal turbulence and differential
pressure. Air flows vertically inside the filter pockets, guided by the corrugated
spacers. This produces a laminar flow into the horizontal fan inlet cone.
