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. RotoClone, 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
(“NFPA”), NFPA 69: Standard on Explosion Prevention Systems. This standard

Filter Company, Inc. d/b/a AAF 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 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 (or vents) are 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 RotoClone LVN will operate with a fan which is installed either on the
ground or on the top of the dust collector. 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 moisture
eliminator is 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 panel 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 RotoClone LVN is a complete dust control unit. Designed to perform its
various functions automatically, the RotoClone requires very little maintenance.
Like any other mechanical equipment, however, it should have regular attention
and be operated according to instructions to insure long life and trouble-free
service.

Filter Company, Inc. d/b/a AAF International.
The RotoClone LVN is a factory assembled, fully self-contained unitary dust
collector. The dust generated by operations is drawn into the collector by
ductwork, into a water bath and then through AAF’s unique static impeller which
causes the dust to mix thoroughly with the water and separate from the air. The
cleaned air is then emitted from the dust collector through the fan located on top
of the collector and separated dust settles to the bottom of the water bath. The
dust forms a sludge which is then periodically removed from the collector.
The RotoClone N can only be operated when it is filled with water to the
correct level. Automatic cut-out devices prevent operation of the fan if the water
level is too low.
3.2 Purpose and intended use
The RotoClone LVN is intended to be used to collect dust that can be
explosive, such as metal dusts, dusts that tend to cause dry collectors to have
problems, such as oily or moisture laden dust, or dusts that can be easily collected
using a water bath. Contact AAF International for assistance on your application.
3.3 Normal Operation
The RotoClone LVN cleans the air by the combined action of centrifugal force
and a thorough mixing of water and dust laden air. The dust is separated from the
air by means of a water curtain, created by the flow of air through a partially
submerged stationary impeller (see Figure 1). Air flowing through the impeller at a
high velocity conveys water with it in a very turbulent sheet. Since there is a
certain differential pressure through the impeller, the water flows upward through
the slot in an attempt to reach the water level on the clean air side. This water
flow upward through the slot creates increased interaction between the dust and
water, thus, increased collection efficiency. The centrifugal force exerted by the
rapid changes in direction of flow causes the dust particle to penetrate the water
film and become permanently trapped. (Figure 1)
Any entrained moisture in the cleaned air is removed by specially designed,
wide spaced chevron eliminators.
The water in the reservoir is continually reused and since the water curtain
is produced by the air flow, no pumps or nozzles are required. The water level is
maintained by the water level probe in the control box as long as a small amount
of fresh water is supplied through the make-up water connection as needed to
compensate for evaporation and water lost as the collected dust is removed from
the unit.

9ASSEMBLY AND INSTALLATION
9.1 Introduction
Safe and efficient operation of the RotoClone LVN depends on proper
installation.
AAF recommends that the ductwork going into the collector be as straight as
possible, with at least 5 diameters of straight run recommended.
Authorities with jurisdiction should be consulted before installing the
RotoClone LVN to insure local installation laws, codes, regulations and procedures
are followed.
A qualified installation and service agent must complete installation and
service of the dust collector and equipment.
Ensure all covers from shipping and loose materials are removed from the
collector before installation. Failure to do so can result in failure of the dust
collector.
Ensure the hardware on the dust collector assemblies are properly installed
and tight before installation.
9.2 Assembling and installing the structure
9.2.1 All Arrangements
1. Set RotoClone on foundation and adjust base until unit is level. Place
spirit level on the leveling strips welded on two or more sides of the
hopper. Use care in leveling both directions as the operation of the
RotoClone depends on the accuracy of the leveling function.
Note: This level can be checked by filling the unit with water until the level
reaches the entering edge (Figure 1) of the impeller. This entering edge
should be level with the water along its entire length with maximum
variation of 1⁄16" plus or minus.
9.2.2 Lubrication
All motor bearings are ball bearings and packed with grease before leaving
the factory. Do not add more grease during installation.

9.2.4 Water supply connections
Units are supplied with a 1” (FPT) quick fill valve and ¼” (FPT) solenoid
valve for automatic water makeup. Connect supply piping to both.
9.2.5 Drain Connection
A 2” (FPT) drain valve is supplied at the bottom of the hopper. Drain piping,
should be attached here and to the 1” (FPT) overflow coupling on the side of the
sludge chute.
9.2.6 Ductwork Installation
In order to prevent surging within the RotoClone, four to five duct diameters
length of straight run prior to the inlet will provide uniform distribution at the inlet.
If an elbow is required due to space constraints, turning vanes must be used in the
elbow to evenly distribute the air and prevent surging.
Inlet and exhaust ductwork must be supported from the floor, wall or
ceiling; not from the RotoClone or fan exhauster. Depending on the application
and local conditions, the discharge from the exhauster may be either returned to
the workroom or discharged to the atmosphere. It may be desirable to have both
outside and inside discharges fitted with a selective damper. This will save heat in
the winter with recirculation and aid ventilation by discharging outside during the
summer months. When a discharge duct is required, it should extend above
adjacent roof lines and should discharge vertically upward. As long as there is a
drain in the fan housing, a drain cap or weather hood should not be used. Cross-
section of the discharge duct should not be less than the exhauster outlet area.
10 Water Level Control Options
Supply water makeup for the RotoClone is required because of water losses
due to evaporation and sludge removal. Makeup water will maintain the proper
water level in the unit by entering the RotoClone through the RotoClone/Control
box connection.
The Model A control is the only water level control available on the
RotoClone LVN.
10.1 Model “A” Control
This control box is used when there can be no water overflow from the
RotoClone. Makeup water will be added to the system only when the requirement
exists. This control also prevents the RotoClone from operating when there is
insufficient water level.

The water supply system contains a fill valve, strainer, solenoid valve,
electrode, electrode holder, and a timing relay.
The electrode and holder are installed in one of the ports on the top of the
box. This low water safety device is designed to be in continuous contact with the
water in the control box. When the water level drops below the electrode, the
solenoid valve opens to supply the required makeup water to the system. When
the control box water level is again in contact with the electrode, the solenoid
valve closes and stops the makeup water flow. This prohibits a continuous water
overflow at the weir.
If the water level has not reached the electrode within three (3) minutes, the
timer will turn off the RotoClone exhauster and stop the RotoClone operation.
NOTE: Since make-up water is only added to replace evaporated water losses and
sludge removal water losses, dissolved solids will build up in the scrubbing water
which can cause increased rates of corrosion. It is recommended that the reservoir
be purged occasionally and pH readings be taken once a week (with litmus paper)
and adjusted to 6.5–7.5.
This range is appropriate for most dusts except aluminum, magnesium, and
titanium, which oxidize and leave a high hydrogen ion content. A high H content
equals a low pH. This can be kept in the 6–6.5 range with an automatic (solenoid
valves on drain and makeup) purge system which lets in fresh water once each
one to four hours. For each gallon of fresh water, a gallon of low pH water is
released.
Be aware that most collected dusts are either inert or biodegradable.
However, dusts which are toxins or heavy metals may not be purged to the
sewage system. Be sure to follow the applicable regulations on this matter.
