Improper operation of dust collectors and/or dust control systems may contribute to conditions in a work area or
facility which could result in severe personal injury, and product or property damage.All dust collection equipment
should be used only for its intended purpose and should be properly selected and sized for its intended use.
Process owners have important responsibilities relating to identifying and addressing potential hazards in their
processes. When the potential for handling combustible dust exists within a process the process owner should
include combustion hazards in their risk management activities and should comply with applicable codes and
standards related to combustible dust.
Electrical installation must be performed by a qualied electrician.
This equipment is not designed to support site ducts, piping, or electrical services.All ducts, piping, or electrical
services must be adequately supported to prevent injury and/or property damage.
Site selection must account for wind, seismic zone, and other load conditions.
Equipment may reach peak sound pressure levels above 80 dB (A). Noise levels should be considered when
selecting collector location.
Most dusts present safety and health hazards that require precautions. Wear eye, respiratory, head and other
protection equipment suitable for the type of dust.
Some components may be heavier than they appear. Use appropriate lifting methods to avoid personal injury and/or
property damage.

Combustible Dust Hazards
Among other considerations, the current NFPAstandards require owners whose processes involve potentially combustible
materials to have a current Dust HazardAnalysis, which can serve as the foundation for their process hazard mitigation strategy.
Mitigation may include but is not limited to:
• Prevention of all ignition sources from entering any dust collection equipment.
• Selection and implementation of re and explosion mitigation, suppression, and isolation strategies appropriate for the
risks in their process.
• Development and use of work practices to maintain safe operating conditions, and to ensure combustible dust does not
accumulate within their plant or process equipment.
Donaldson designs, manufactures, and sells industrial air ltration products for a wide variety of applications. Some applications
may include processes or materials with inherent re and explosion hazards. Donaldson is neither an expert nor a certied
consultant in re, spark, or explosion detection, suppression, or control. Donaldson does not provide engineering consulting
services related to process or dust hazard analyses, or code and standard compliance. Complying with applicable codes and
standards and managing the risks associated with the process or materials remains the responsibility of the process owner/
operator. Donaldson may provide referrals to consultants, suppliers of equipment or services related to the detection and/
or mitigation of sparks, res and/or explosions, but Donaldson does not assume responsibility for any such referrals, nor does
Donaldson assume any liability for the tness of a mitigation strategy or product for a particular installation or application. The
process owner’s nal selection of dust collectors and risk mitigation strategies should be based on the outcome of a Dust Hazard /
Process HazardAnalysis performed by the process owner.Although early engagement of a dust collector supplier provides helpful
insights on the availability and features of various products, process owners should consult with a combustible dust expert and/or a
process safety expert before making actual product and mitigation strategy selections.
Donaldson recommends that all industrial air ltration system designs be reviewed and approved by an expert consultant who is
responsible for the integrity of the system design and compliance with applicable codes and standards. It is the process owner’s
responsibility to understand the risks in their process and mitigate those risks in accordance with all applicable laws, regulations
and standards, including those published by the NFPA. Donaldson also recommends that proper maintenance and housekeeping
procedures and work practices be evaluated, developed, and followed to maintain any industrial air ltration products in safe
operating condition.
Many factors beyond the control of Donaldson can affect the use and performance of Donaldson products in a particular
application, including the conditions under which the product is used. Since these factors are uniquely within the user’s knowledge
and control, it is essential the user evaluate the Donaldson products to determine whether the product is t for the particular
purpose and suitable for the user’s application. All products, product specications, and data (airow, capacity, dimensions, or
availability) are subject to change without notice, and may vary by region or country.

The Rugged Pleat (RP) Baghouse is a continuous duty dust collector with pleated lters designed to handle applications with
heavy dust loads. Continuous-duty means the lters can be pulse cleaned on-line without interrupting airow through the collector.
The cleaning system logic monitors the arm location and ensures pulses are delivered directly on the centerline of lters to
optimize cleaning with all lters being cleaned every four minutes.
The cylindrical collector housing design features an all-welded construction in standard sizes from 70 to 272 lter with 60-inch
pleated bags available in various media types. The collector housing design can include a SuperSep™ low body inlet or an upper
body radial high inlet with replaceable wear inserts.
The SuperSep™ inlets are typically used for heavy non-abrasive dust handling applications. These inlet styles allow the majority
of the incoming dust to cyclonically separate. The heavier dust is directed downward into the hopper while the lighter dust is
passed through air straightening vanes to evenly distribute the air and entrained dusts over the lters for nal separation.
The upper body radial style high inlet is typically used on highly abrasive dust type applications. This style of inlet is located in
the lter housing section below the tubesheet and directs the incoming dust particles into a replaceable impaction zone then
downward around the lters and into the hopper. This ow path reduces abrasion and assists the cleaning system by supporting
an airow pattern that encourages the dislodged dust pulsed off the lters to move downward into the hopper. Bafes in the inlet
keep dusts from directly abrading on the lter bodies.
RP Baghouses come standard with a walk-in Clean-Air Plenum (CAP). Filters, pulse and drive components can be serviced on
the clean air side of the collector within the walk-in plenum.Access to the CleanAir Plenum is provided by an optional ladder and
platform system.
The RP Baghouse collector is ideal for applications in the woodworking, grain and mining industries where it effectively handles
high-volume, high dust-load applications.Additional applications include cement, chemical and food processing applications.
The RP Baghouse is typically used in applications between 10,000-55,000 cfm.
Sizes are available for lower airow applications with any of the following conditions or requirements:
• Heavy dust load
• No compressed air available
• Around collector required for sanitary reasons
• High pressure or vacuum requirement
• Arequirement for a single discharge hopper.
Operations involving higher temperatures, humidity, or air stream chemistry may require customized collector design options.

Standard Equipment
All welded collectors can be lifted from the truck to the prepared site.
Platform and Ladder
Access ladder to the platform and door to enter the Clean Air Plenum for maintenance such as lter changes, mechanical work on
the pulse arm and drive and pulse system, and electrical work on the pulse system.
Hopper Access Cover
Access cover which when removed allows access to the DirtyAir Plenum (DAP).
SuperSep™ Inlet
Atangentially oriented inlet where the dirty air enters the DirtyAir Plenum. Various features in the inlet section promote the dropout
of dust through cyclonic action and bafing to reduce dust loading to the lters and features above the inlet reduce air rotation or
spin to improve the distribution of air to the lters.
High Inlet
Anon-cyclonic inlet designed for abrasive dusts.
Outlet
Located on the CleanAir Plenum and where the clean air exits the collector and typically is routed to the fan.
Hopper Outlet
The hopper outlet is a singular outlet on the DirtyAir Plenum where the separated dust exits the collector and is routed to be
disposed of via bin, pneumatic conveyor, screw conveyor, or other means.Arotary airlock is typically used to isolate the dust
collection system from the dust disposal system.
Hopper Transition
Atransition from the typical outlet to a variety of dust disposal device options available through Donaldson or other Manufacturers.
Collector Body
The combination of the Dirty and CleanAir plenums represents the total collector body.
Leg Pack
Leg structure supports the collector body at an elevation to accommodate various dust disposal devices and systems which can be
congured to meet customer needs.
Positive Displacement (PD) Pump
Positive Displacement air pump which supplies air to the pulse system typically at 7.5psig. Using a PD pump for the pulse system
reduces the cost of the compressed air and reduces issues related to remote supplied compressed air dew points and supply
issues.
CAP
Clean Air Plenum where ltered air enters after passing through the lters as it travels to the outlet.
Cleaning System
Single pulse valve system with a rotary arm that pivots around the center of the collector efciently allowing for the cleaning of
all lters directly on the centerline of each lter. The single valve design reduces the maintenance typical of multi valve and multi
bank systems.

Tubesheet
Metal panel the lters are sealed against to separate the Dirty Air and Clean Air Plenums of the collector. Through holes are cut to
mount lters.
Spoke
Radial line from the center of the tubesheet through lter openings at the outer most ring. All of the lters fall on these radial lines
allowing the lters to be pulsed.
Filter Assembly
Includes pleated lter media attached to a soft polymer cuff and/or metal pan that mounts into the tubesheet with a radial seal
and an expanding insert that presses in and locks down to seal the lter assembly against dust bypass. The lter assembly
incorporates both a venturi geometry and tertiary holes to improve the pulse cleaning characteristics.
Clean Air Plenum (CAP) Door
Access door from the platform to allow entry into the CleanAir Plenum for service and inspection.
Dirty Air Plenum (DAP)
DirtyAir Plenum where dust laden process air enters the body of the dust collector through the inlet.As air enters it goes through a
preseparation stage and then airow straightening before it reaches the lters. This allows the majority of the dust to drop out into
the hopper and the airow to be evened out before it gets to the lters.
Hopper
Discharge point for dust that has been preseparated and pulsed off of the lters.
Filter
Consists of a soft polymer cuff and/or metal pan, an internal structure, pleated lter media, and an end cap of either polymer or a
potted metal cap. Filters dust from the airstream on the outside of the lter before entering the DAP.
Reservoir Tank
Central tank which holds compressed air supplied by PD pump for pulsing. The tank is the mounting point for the drive package
and pulsing components.
Arm Drive
Consists of a gearbox, motor, tensioner, sprockets, and chain. This rotates the arm around the centerline of the collector to
distribute the pulses around the tubesheet.
Arm Assembly
A “Tee” or “L” shaped assembly with nozzles along the bottom to pulse air directly into the centerline of the lter openings. The Arm
Assembly rotates around the centerline of the collector.
H Frame
An “H” shaped structure that supports the pulse system.

Pulse Solenoid
This converts an electrical signal from the timer to the mechanical release of air from the secondary diaphragm for a prescribed
duration during each pulse.
Diaphragm Primary
The large diaphragm mounted directly to the air tank under the large cast aluminum cap. This is actuated by the secondary
diaphragm and releases compressed air to the arm assembly and pulse the lters.
Diaphragm Secondary
The small diaphragm mounted between the solenoid and primary diaphragm. This is actuated by the solenoid and triggers release
of compressed air by the primary diaphragm.
Sensor Switch and Target
Asensor switch and targeting magnet that work in combination to provide the controller both arm position and speed to ensure
proper pulse alignment and proper timing between pulses.
Cleaning Logic
Using signals from the Sensor Switch and Target, the Cleaning Logic Controller sets the time delay between pulses and adjusts
pulse duration to ensure all lters are pulsed on their centerline within four minutes, while avoiding situations where a lter is
cleaned adjacent to a recently cleaned lter.
Helix
Spiral strip starting at the inlet and spiraling down to the top of the hopper at 180 deg. Helps encourage small particulate
preseparation and prevent dust migration upward towards the lter section.
Strakes
Two at perpendicular surfaces in the lower hopper that disrupt the cyclonic action to improve dropout and terminate the cyclonic
action before entering the dust disposal system.
EvenFlow Ba󰀪es™
Engineered vanes which reduce the cyclonic swirl of the airow and provide more uniform ow into the Dirty Air Plenum section
containing the lters.

Donaldson Company, Inc.
3 Operation
Electrical work during installation, service or maintenance must be performed by a qualied electrician and comply
with all applicable national and local codes.
Turn power off and lock out all power before performing service or maintenance work.
Turn compressed air supply off, bleed and lock out lines before performing service or maintenance work.
Check that the collector is clear and free of all debris before starting.
Do not install in classied hazardous atmospheres without an enclosure rated for the application.
The RP Baghouse cleaning system consists of two opposing arms which rotates around the center of the collectors CAP. This
system uses medium pressure air (7.5 PSI) generated by a PD pump typically located at ground level to charge a holding tank.
The system has a 2 stage diaphragm valve set to provide the pulse air when a solenoid is activated.
The solenoid activation is controlled by a pulse controller which calculates the position of the arm using a proprietary system to
determine the position of the arm based on a xed sensor. This allows the pulse to be oriented directly into the centerline of the
lter to deliver the most effective pulse possible all while properly distributing the pulses around the entirety of the tubesheet to
eliminate wasted pulses. Refer toAppendixAfor pulse system alignment instructions.
Tangential Inlet Operation
During normal operation of an RP Baghouse with a tangential inlet, dust-laden air enters the dirty-air inlet.The tangential inlet
induces a cyclonic action which pre-seperates the majority of the particulate from the dirty airstream. During this process the
dirty air passes by the helix and hopper strakes causing further dropout of particulate. As the airow transitions upward within the
collector, the airow straighteners reduce the cyclonic action, straightening and distributing the airow to the lter elements above.
The remaining particulate is separated from the airstream by the pleated lter bags. The clean ltered air continues on through the
CAP and is either exhausted to the ambient air or returned to the facility. The dust left behind forms a “cake” on the outside of the
lters.
As the dust “cake” becomes thicker and less permeable, the pressure drop across the lter rises. To reduce and maintain pressure
drop across the lter bags, a pulse cleaning system is employed.
High Inlet Operation
During normal operation of an RP Baghouse with a high inlet, dust-laden air enters the dirty-air inlet.The high inlet section
contains bafes that prevent the abrasion of lters by directing the incoming dust particles into a replaceable impaction zone then
downward around the lters and into the hopper. This ow path reduces abrasion and assists the cleaning system by supporting
an airow pattern that encourages the dust dislodged when the lter is pulsed to move downward into the hopper. Bafes in the
inlet keep dusts from directly abrading on the lter bodies.

Typical Collector Operation Sequence
Start-Up
Verify the process system is ready for operation and all alarm conditions are cleared prior to starting the collector.
1. Start waste dust systems.
a. Pneumatic conveying, compactor, RAL or screw conveyor
b. Look for upset conditions upon start/waiting to clear/monitor for dust accumulation
2. Start pulse system.
a. Cleaning arm drive
b. Pulse logic
c. PD pump
3. Start main blower.
Shut-Down
1. Shut off main blower.
Slowly ramping down airow will allow accumulated dust to drop into the hopper gradually while the
collector continues cleaning. An abrupt reduction in airow may result in one large release of dust from
the lters which may plug the hopper discharge.
2. Stop pulse system (pulse with no airow for a short period of time in order to get better dust discharge and to reduce dust
buildup prior to restarting system).
3. Stop waste dust system once system is clear (continue running until no additional material discharge is noted).
*Reference control panel IOM for control specic startup instructions.
