Data Sheet
Process owners/operators have important responsibilities relating to combustible hazards.
Process owners/operators must determine whether their process creates combustible dust,
fume, or mist. If combustible dust, fume, or mist is generated, process owners/operators should at a
minimum:
• Comply with all applicable codes and standards. Among other considerations, current NFPA standards
require owners/operators whose processes involve potentially combustible materials to have a current
Hazard Analysis, which can serve as the foundation for their process hazard mitigation strategies.
• Prevent all ignition sources from entering any dust collection equipment.
• Design, select, and implement fire and explosion mitigation, suppression, and isolation strategies that
are appropriate for the risks associated with their application.
• Develop and implement maintenance work practices to maintain a safe operating environment, ensuring
that combustible dust, fume, or mist does not accumulate within the plant.
Donaldson recommends process owners/operators consult with experts to insure each of these
responsibilities are met.
As a manufacturer and supplier of Industrial Filtration Products, Donaldson can assist process owners/
operators in the selection of filtration technologies. However, process owners/operators retain all
responsibility for the suitability of fire and explosion hazard mitigation, suppression, and isolation strategies.
Donaldson assumes no responsibility or liability for the suitability of any fire and/or explosion mitigation
strategy, or any items incorporated into a collector as part of an owner/operators hazard mitigation strategy.
Improper operation of a dust control system may contribute to conditions in the work area or facility that
could result in severe personal injury and product or property damage. Check that all collection equipment is
properly selected and sized for the intended use.
DO NOT operate this equipment until you have read and understand the instruction warnings in the
Installation and Operations Manual. For a replacement manual, contact Donaldson Torit.
This manual contains specific precautionary statements relative to worker safety. Read thoroughly and comply
as directed. Discuss the use and application of this equipment with a Donaldson Torit representative. Instruct all
personnel on safe use and maintenance procedures.

Donaldson Company, Inc.
Combustible materials such as buffing lint, paper, wood, metal dusts, weld fume, or flammable
coolants or solvents represent potential fire and/or explosion hazards. Use special care when
selecting, installing, and operating all dust, fume, or mist collection equipment when such combustible
materials may be present in order to protect workers and property from serious injury or damage due to a
fire and/or explosion.
Consult and comply with all National and Local Codes related to fire and/or explosion properties of
combustible materials when determining the location and operation of all dust, fume, or mist collection
equipment.
Standard Donaldson Torit equipment is not equipped with fire extinguishing or explosion protection systems.
The Dryflo mist collector, Models MMA and MMB, mount
directly to a machining center to collect airborne mist
such as oil, water-soluble, and synthetic coolant from
machining operations. Three stages of filtration, plus an
optional HEPA filter, provide a cleaner, healthier work
environment as well as a more cost effective means
of mist collection. With airflow capacities from 390 to
800 cfm, the Dryflo is a strategic component to meeting
industrial and government air-quality standards. The high
efficiency filter cartridges allow air and coolants to be
recycled and the cartridge efficiency actually increases
as the collector operates.
Designed to increase the versatility of the collector,
standard options include inlet hoppers, impact
separators, drain collection methods and an adjustable
stand. A variety of filter media specifically designed
for mist collection, from heavy liquid-load to heavy
particulate-load applications, is also available.
Airborne mist is small droplets of liquid suspended in the
air. Dryflo mist collectors are widely used in machine
tool operations using metalworking fluids. Metalworking
fluids include straight oil, water-soluble coolants, soluble
oil, and semi-synthetic coolants. These fluids perform
a variety of functions such as lubricating or cooling the
part or the tool, flushing chips away from the part, and
suppressing dust and smoke. Oils and coolants allow
machines to operate faster and tools to last longer
resulting in high quality parts.
Mist is created two ways: mechanical action or thermal
effects. Mechanical action refers to aerosol used for
light lubrication and generally creates mist greater than
one micron in size. Thermal effects occur when heat
vaporizes the coolant; the vapor cools and recondenses
into a mist. Thermal effects create mist from 0.01 to 1
micron in size. Other contaminants, such as dust from the
part or the tool or smoke from the combustion of the oil
or coolant are also generated when using metalworking
fluids.
The Dryflo can collect some dust with the mist; however,
it should not be operated without mist. The collector is
not designed to handle water mist alone. There should be
some type of material to allow coalescing, or water vapor
will pass through the filters. The extremes of very heavy
oil and light, thin oil should be avoided. Very heavy oil,
similar to tar consistency, will not drain while very light,
thin oil, similar to gasoline consistency, may evaporate.

in severe personal injury and/or
property damage.

Donaldson Company, Inc.
During normal operation, contaminated air enters the
collector through the dirty-air inlet on the bottom of the
unit. The air passes through a reusable first-stage filter
designed to collect and coalesce large droplets and
particles. Smaller mist droplets pass to a second-stage
filter wrap where the small droplets coalesce into larger
droplets.
The third and most efficient stage of filtration is the
pleated filter specifically designed to collect, coalesce,
and drain fine mist. As the mist coalesce, the droplets are
big enough to run down the element and drain back into
the collector. The droplets will drain on both the inside
and outside of the filter cartridge. Liquid that collects on
the inside of the cartridge drains back into the machine
center. Clean, mist-free air exits the filter cartridge and
discharge through the top of the collector.
