CAUTION!
Application of Mist Control Equipment
• Combustible materials such as buffing lint, rouge, aluminum and steel dust, weld fume,
or flammable solvents represent fire or explosion hazards. Use special care when
selecting and operating all mist collection equipment when combustible materials are
present to protect workers and property from damage due to fire and/or explosion.
Consult and comply with National and Local Codes relating to fire or explosion, and
all other appropriate codes when determining the location and operation of mist
collection equipment.
• When combustible materials are present, consult with an installer of fire extinguishing
systems familiar with these types of fire hazards and local fire codes for
recommendations and installation of fire extinguishing and explosion protection
systems. Donaldson Dust Collection equipment is not equipped with fire extinguishing
or explosion protection systems.
•DO NOT allow sparks, cigarettes, or other burning objects to enter the hood or duct
of any mist control equipment.
• For optimum collector performance, use only Donaldson replacement parts.
Warning – Improper operation of a mist control system may result in 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.

Description
The Modular MediaFilter –Horizontal Series
source collectors are designed to collect airborne
mist such as oil- or water-soluble, and synthetic
coolant from machining operations. Two stages of
filtration plus an optional HEPA filter provide a
cleaner, healthier work environment as well as a
more cost efficient means of mist collection. With
airflow capacities from 1,500 to 3,000 cfm, the
Modular MediaFilter –Horizontal Series source
collector is a strategic component to meeting
industrial and government air-quality standards.
The high efficiency filter system allows filtered air
to be returned to the plant environment.
Designed to increase the versatility of the unit,
standard options include motor starter controls,
drain collection containers, and control boxes with
remote START/STOP or machine interlock
capabilities. A variety of filter media specifically
designed for mist collection, from heavy liquid-load
to heavy particulate-load applications, is also
available.
Purpose and Intended Use
Airborne mist is small droplets of liquid that are
suspended in the air. Modular MediaFilter—
Horizontal Series collectors are widely used in
machine tool operations where metalworking fluids
are used. 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 and should be considered when
selecting equipment.

Unit Operation
Operation
During normal operation, contaminated air enters
the unit through one of the two side inlet collars.
The dirty-air plenum is designed to reduce the
incoming airflow velocity and cause large droplets
to separate from the airstream. The reduced-
velocity air passes across an impactor plate which
separates the droplets from the airstream where
they fall into the first hopper. 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
fiberglass vee-bag filter. The vee-bag’s open pleat
design and precise bag spacing allows contaminant
loading throughout the life of the filter. As mist
particles coalesce and form large droplets, the
droplets run down into the bottom of the filter and
drain into the second hopper. The collected liquid
drains from both hoppers into
P-traps or collection bottles. Clean, mist-free air
exits the filter and discharges through the end of
the collector.

Magnehelic Gauge
The Magnehelic is a differential pressure gauge
used to measure the pressure difference between
the clean- and dirty-air chambers and provides a
visual display of filter change requirements. The
high-pressure tap is located in the dirty-air
chamber and the low-pressure tap is connected to
the clean-air chamber.
1. Choose a convenient, accessible location on or
near the unit for mounting that provides the
best visual advantage.
If unit is equipped with factory-installed pressure
taps, skip to Step 5.
2. Before drilling, place a piece of non-combustible
cloth over the filter opening in the clean-air
chamber to protect them from drilling chips.
3. Place a piece of wood behind the drill location
in the dirty-air chamber to protect the filters
from damage by the drill bit. Use a .406-inch
diameter bit to drill the holes.
4. Mount the pressure tap hardware in the clean-
and dirty-air chambers.
5. Plug the pressure ports on the back of the gauge
using two, 1/8-in NPT pipe plugs supplied.
Install two, 1/8-in NPT male adapters supplied
with the gauge into the high- and low-pressure
ports on the side of the gauge. Attach the
mounting bracket using three, #6-32 x 1/4-in
screws supplied.
