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.

Split Taper™ Bushing Mounting Instructions
Many fans are furnished with split taper bushings
for mounting the impeller to the shaft. When
properly assembled, the bushings grip the hub with
a positive clamping action.
1. Bushel barrel and bore of impeller are tapered
to ensure concentric mounting and a true
running propeller.
2. Capscrews, when tightened, lock bushing in
propeller. Use special plated capscrews and
nylock nuts.
3. Bushing is split so that when the locking
capscrews force bushing into tapered bore, the
bushing grips the shaft with a positive clamping
fit. This will withstand vibration and heavy
loads without being loosened.
4. Impeller and bushing assembly is keyed to the
shaft and held in place by compression, which
adds driving strength.
Note: Before assembly, ensure shaft and
keyway are clean and smooth.
Check key size with both shaft and
bushing keyway.
5. To assemble, insert the capscrews through the
clearance holes in the bushing and install
bushing loosely into the impeller. Do not press
or drive. Start capscrews by hand, turning them
just enough to engage threads in the nylock nut.
Do not use a wrench at this time. The bushing
should be loose enough in the propeller to move
freely. Slide impeller and bushing assembly onto
shaft, allowing adequate clearance for shaft
end play to prevent friction. Fit key into
keyway. Do not force impeller and bushing
onto shaft. If it does not go on easily, check
shaft, bushing, and key sizes once again.
Tighten capscrews gradually and evenly with
wrench similar to mounting an automobile
wheel. Rotate a quarter turn on each capscrew
successively until all capscrews are tight.
These capscrews force the taper bushing into
the hub, which in turn compresses the bushing
onto the shaft. This makes a positive clamping
fit. The torque must not exceed the value
specified in the table.
CAUTION!
Do not attempt to pull bushing flange
flush with hub end. There should be a
clearance which varies approximately
3/16-in to 1/4-in with the bushing size
when tightened. This is not a locating
dimension.
Impeller Assembly Removal
1. Remove all capscrews from impeller and hub
assembly.
2. Insert capscrews into the threaded holes in the
bushing flange.
3. Tighten each bolt in quarter of a turn
increments to push the impeller off the bushing.
This forces the bushing loose from the propeller
hub and releases the compression so that the
entire assembly will slide from the shaft.
4. Pull the bushing off the shaft.
Note: If the assembly has been in place
sometime it may be necessary to use a
wheel puller to remove the bushing.
Never use a wheel puller on the impeller.
