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 NFPA standards require owners whose processes involve potentially combustible
materials to have a current Dust Hazard Analysis, 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 Hazard Analysis 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.

2 Product Description
Standard Equipment
All welded collectors can be lifted from the truck to the prepared site.
Hopper Access Cover
The access cover, when removed, allows access to the interior of the hopper.
Clean Air Outlet
Clean air exists the collector through the clean air outlet located in the clean air plenum.
The LP Baghouse is a continuous duty dust collector with bag-style lters designed to handle up to 141,000 cfm depending on the
application and dust type. Continuous duty means the lters can be reverse air cleaned on-line without interrupting airow through
the collector. All bags are cleaned with every revolution of the cleaning arm.
The LP features a walk-in clean-air plenum, allowing lter bag service from inside the clean air plenum.
Intended Use
The LP Baghouse collector is common in the nut, woodworking and grain industries where it effectively handles high-volume, high
dust-load applications.
Sizes are available for applications with any of the following conditions or requirements:
• Heavy dust load
• No compressed air available
• A requirement for a single discharge hopper
Filters
The LP collector ships with lter bags and cages. The standard bag media is Dura-Life™ which provides long life and energy
savings due to lower pressure drop. Other lter bag media options are available.
Involute Scroll Style Inlet
The inlet develops a cyclonic airow causing heavier particulate to drop directly into the hopper. The air continues through an
internal ow straightener, reduces turbulence and evenly distributes the dust-laden air within the collector cross-section and around
the lter bags.
Reverse Air Cleaning System
The cleaning system contains an internal fan with reverse air ow design. The sweep arms have a ow-stop plate which briey
keeps air from owing through the bag lters after cleaning. This feature reduces the chances of dust from cleaned bags being
re-entrained onto recently cleaned bags, resulting in lower pressure drop and reduced energy costs due to bags staying cleaner
longer. The system does not require any compressed air supply.
Rating and Specication Information
General rating and specication information can be found in the product literature provided with the collector and is available on the
Donaldson website. For specic load values for a collector, see the Specication Control Drawing shipped with the collector.

72LP - 252LP Baghouse

Collector Body
The combination of the Dirty and Clean Air plenums along with the hopper represents the total collector body.
Leg Pack
The 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.
Clean Air Plenum (CAP)
Air passes through the lters and into the Clean Air Plenum(CAP) where it exists through the Clean Air Outlet.
Tubesheet
The tubesheet is the 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.
Clean Air Plenum (CAP) Door
The Clean Air Plenum (VAP) door allows access into the Clean Air Plenum for service and inspection.
Dirty Air Plenum (DAP)
Dust laden process air enters the Dirty Air Plenum via the involute scroll 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
The hopper, located at the bottom of the collector body, is the discharge point for dust that has been preseparated and pulsed off
of the lters.
Arm Drive
The arm drive consists of a gearbox, motor, tensioner, sprockets, and chain. This rotates the arm around the centerline of the
collector to distribute the cleaning air.
Sweep Arm Assembly
The sweep arm assembly is a “Tee” or “L” shaped assembly with nozzles along the bottom to distribute the cleaning air into the
lter bags. The arm assembly rotates around the centerline of the collector.
H Frame
An “H” shaped structure that supports the reverse air cleaing system.
Hopper Outlet
The hopper outlet is a singular outlet at the bottom of the hopper where the separated dust exits the collector and is routed to
be disposed of via bin, pneumatic conveyor, screw conveyor, or other means. A rotary airlock is typically used to isolate the dust
collection system from the dust disposal system.

Donaldson Company, Inc.
Platform and Ladder
Collector may be equipped with a ladder and platform system for gaining access to the clean air plenum for lter bag changeout.
For all ladders over 24-ft OSHA requires a ladder safety system or personal fall arrest system. As a convenience, Donaldson offers
ladder safety systems as an option.
Explosion Relief Panels
Collector may be equipped with optional explosion relief panels to support a process owners combustible dust mitigation strategy.
Explosion vent sizing follows NFPA-68 formulas assuming outdoor location of collector with no duct or obstruction on the explosion
vent panels. Contact Donaldson Torit for explosion venting requirements for other conditions.
Sprinkler Coupling
Sprinkler couplings are provided for the convenience of re control system installers. The re control system installer shall make
their own decisions on the appropriate location of re control system components.
Water Overow Valve
An optional means to allow water evacuation. Some method of water evacuation must be provided if a water based extinguishing
system is installed on the collector.
Cleaning Controls and Sensors
Magnehelic®Gauge
Simple mechanical gauges that measure differential pressure. May be passive mechanical versions or digital, may include
electrical contacts and user adjustable setpoints.
Hopper Discharge Accessories
Hopper Transition
The collector comes with a standard size hopper outlet. Donaldson offers optional hopper outlet transitions to match up with
various dust disposal devices.
Live Bottom Hopper
Short section of screw conveyor with a round to rectangle transition that handles tough dusts that bridge easily.
Rotary Airlock (RAL)
Used to isolate the dust collection system pressure from atmosphere. Options include exible wipers, NFPA rated valves,
Pneumatic conveying ready valves, and high clearance valves for tough to handle dusts.
Screw Conveyor
Can be mounted directly to the hopper outlet with the addition of an RAL at the discharge. Useful for loading bulk containers while
maintaining a shorter overall height.

3 Operation
The LP cleaning system contains an internal fan with reverse air ow design. The sweep arms have a ow-stop plate which briey
keeps air from owing through the bag lters after cleaning. This feature reduces the chances of dust from cleaned bags being
re-entrained onto recently cleaned bags, resulting in lower pressure drop and reduced energy costs due to bags staying cleaner
longer. The system does not require any compressed air supply.
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.
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.
During normal operation, dust-laden air enters the dirty-air inlet. The involute scroll-style inlet develops a cyclonic airow causing
heavier particulate to drop directly into the hopper. The air continues through an internal ow straightener that evenly distributes
the dust-laden air within the collector cross-section and around the lter bags. After entering the collector the light dust collects on
the outside surface of each lter bag forming a dust cake. Clean, ltered air passes through the lter bags to the clean-air plenum
and discharges through the clean-air outlet.
Typical Collector Operation
Typical Start-Up Sequence
1. Start rotary airlock (if applicable).
2. Start gear box motor for cleaning arm rotation.
3. Start reverse-air cleaning assembly fan.
4. Start main system fan.
5. Start process equipment.
Typical Shut-Down Sequence
1. Stop process equipment. Allow LP to continue operating for 3-5 minutes. Fan remains running to clear dust from conveying
ducts and areas around hoods.
2. Stop main system fan. Allow LP reverse-air fan and gear box motor to continue running for 15-10 minutes. Cleaning remains
active after main system fan shuts off to allow for a brief period of enhanced lter bag cleaning.
3. Stop LP reverse-air fan and gear box motor. Allow airlock to run for at least 5 minutes after reverse-air fan and gear box motor
shut off to ensure dust is fully evacuated from the hopper of the LP.
4. Stop airlock.
