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.
1 Safety Communication

LP Panelized Baghouse 684LP - 882LP
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.

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.
Tangential 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.
Tubesheet
The tubesheet separates the dirty-air plenum from the clean-air plenum while supporting the lter elements and cleaning system.
Clean-Air Access Plenum, Clean-Air Outlet, Roof
Clean, ltered air ows up through the tubesheet, through the clean-air access plenum and out the clean-air outlet.
Dirty-Air Plenum
Evenly distributed dust-laden air ows through the dirty-air plenum, around the lter bags, and clean-air exits through the
tubesheet.
Hopper, Transition
Dust which drops out from the tangential inlet, along with dust being constantly cleaned from the lter elements exits the LP
system through the hopper and transition. Access into the hopper and transition is also provided through the access panel located
on the transition.
The hopper of the LP is not intended for dust storage.
Leg Pack/Support Structure
The entire LP collector is supported by the leg pack/support structure.
Standard Equipment
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 is the recommended collector selection 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
2 Product Description

LP Panelized Baghouse 684LP - 882LP
Explosion Vent
Personal injury, death, and/or property damage can result from material discharge during venting.
The material discharged during the venting of an explosion must be safely directed outdoors away from areas
occupied by personnel to reduce risk of personal injury and/or property damage.
The risk of personal injury and/or property damage can be minimized or avoided by locating vented equipment
outside buildings and away from normally occupied areas.
Explosion vents should be inspected regularly to conrm physical and operational condition. Replace any damaged
parts immediately.
Standard explosion vents are intended for outdoor installations only.
Unless otherwise noted, the explosion venting calculations are based on formulas from NFPA-68 for outdoor applications only, with
no duct or obstructions on the explosion vent panel.
Contact Donaldson Torit for assistance in calculating specic venting requirements for equipment.
NFPA 68 can provide guidance on both the frequency of and appropriate details for inspections.
Platform/Ladder
Collector may be equipped with a platform/ladder system for gaining access to the clean-air plenum for lter bag changeout. For all
ladders over 24-ft installed November 19, 2018 or later, OSHA requires a ladder safety system or personal fall arrest system. As a
convenience, Donaldson offers ladder safety systems as an option.

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.
During normal operation, dust-laden air enters the dirty-air inlet. The tangential inlet with helix 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.
3 Operation
Typical Collector Start-Up/Shut-Down Sequence
Start-Up
1. Start material discharge mechanism such as a 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.
Shut-Down
1. Stop process equipment. Allow main system fan and LP to continue operating for 10-15 minutes to clear dust from conveying
ducts.
2. Stop main system fan. Allow LP reverse-air fan and gear box motor to continue running for 5-10 minutes for a brief period of
enhanced lter bag cleaning.
3. Stop LP reverse-air fan and gear box motor. Allow material discharge mechanisms to run for 10-15 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 material discharge mechanism.
Reverse Air Internal Cleaning System
The cleaning system contains an internal fan with reverse air ow design. The sweep arms have a ow-stop plate which keeps air
from owing through the bag lters before and 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.
