Donaldson Company, Inc.

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 qualiﬁed 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.

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 ﬁre 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 recommends process owners consult experts in combustion risks to ensure these responsibilities are met.

Some processes may involve materials or processes which have inherent ﬁre and explosion hazards. The process

owner retains responsibility to comply with applicable codes and standards and to manage the risks associated

with the process or materials. Donaldson is neither an expert nor a certiﬁed consultant in ﬁre, 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.

Donaldson may provide referrals to consultants and/or suppliers of equipment or services related to the detection and/

or mitigation of sparks, ﬁres and/or explosions, but Donaldson does not assume responsibility for any such referrals,

nor does Donaldson assume any liability for the ﬁtness of a mitigation strategy or product for a particular installation

or application. The process owner’s ﬁnal selection of dust collection 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 can provide helpful insights on the availability and features of various products, process

owners should consult with combustible dust experts and/or process safety experts before making actual product and

mitigation strategy selections.

Donaldson recommends all industrial air ﬁltration system designs be reviewed and approved by an expert consultant

responsible for the integrity of the system design and compliance with applicable codes and standards. It is the

process owner’s responsibility to understand 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

proper maintenance and housekeeping procedures and work practices be evaluated, developed, and followed to

maintain any industrial air ﬁltration 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 ﬁt for the particular purpose and suitable for the user’s application.

Safety Communication

Downﬂo Evolution, DFE 2-8 to 5-80

Description

The Downﬂo®Evolution dust collector is a continuous-

duty, modular collector with cartridge-style ﬁlters.

The downward airﬂow design delivers high ﬁltration

efﬁciency while using less energy. Continuous duty

means the ﬁlters can be pulse cleaned on-line without

interrupting airﬂow through the collector. The ﬁlters are

pulse-cleaned in sequence, one set at a time, without

turning the collector off. Each standard collector is two

or three ﬁlter columns wide by two, three, four, or ﬁve

ﬁlter rows high by two ﬁlters deep.

Designed to increase the versatility of the collector,

standard options include abrasion-resistant inlets,

extended dirty-air plenums, air management modules

and clean change options.

Downﬂo Evolution collectors are intended for ﬁltration

of nuisance dust where the dust loading to the collector

is less than ﬁve grains per cubic foot. Some typical

applications include metal grinding, plasma cutting,

dry bulk, pharmaceutical, thermal spray, welding,

metal manufacturing, glass, and food processing. Each

application is different and selecting the correct ﬁlter

for the application and dust being collected is important.

Contact Donaldson Torit for selection assistance.

• Ambient, extremely ﬁne, and non-ﬁbrous dusts,

typically are well served by Ultra Web®ﬁlters

which offer high efﬁciency and performance on ﬁne

particulate.

• Fibrous dusts often beneﬁt from a ﬁlter with an open-

pleat design, such as Fibra-Web®.

• Operations involving high temperature and high

humidity may require special attention. Temperature,

moisture content, and chemistry issues may also

require custom collector design.

• Hygroscopic dust such as fertilizer, salt, and sugar

should be handled under a controlled, low humidity

environment.

• Flammable or explosive dust may require customized

collector design options.

• Applications with high hydrocarbon or high oil

content may require special treatment or ﬁlter media.

Purpose and Intended Use

Misuse or modiﬁcation may result

in severe personal injury and/or

property damage.

Do not misuse or modify.

Donaldson Company, Inc.

Collector Operation

Operation

During normal operation, dust-laden air enters the

collector through the dirty-air inlet, which is positioned

over the venturi section of the dirty air plenum. Airﬂow

is directed downward through the collector over the

venturis and heavier particulate falls directly into the

hopper. The ﬁlters remove ﬁne particulate allowing

ﬁltered air to pass through the ﬁlters to the clean-air

plenum where it discharges through the clean-air outlet.

Filter cleaning is completed using pulse-jet technology.

A solenoid and diaphragm valve aligned to each row

of ﬁlters provides the pulse cleaning. The cleaning

sequence starts at the top ﬁlter row and continues down

through the module. Removal, inspection, or replacement

of ﬁlters can be accomplished from outside the collector

by removing the ﬁlter access cover and sliding the ﬁlters

out.

Rating and Speciﬁcation

Information

General rating and speciﬁcation information can be

found in the product literature provided with the collector

or available on the Donaldson website. For speciﬁc

load values for a collector, see the Speciﬁcation Control
