ANY INSTALLATION OR OPERATION OF THIS DUST COLLECTOR. MA E SURE YOU ARE IN COMPLIANCE
WITH ALL LOCAL, STATE, FEDERAL AND SAFETY GUIDELINES, REGULATIONS AND STANDARDS.
The National Fire Protection Association (NFPA) has
defined the following materials as “reactive metals”:
Aluminum, Magnesium, Tantalum, Titanium and
Zirconium.
Improper handling, machining, collection and disposal of
these materials can result in a severe explosion and/or fire
resulting in death, severe personal injury and extensive,
immediate and surrounding property damage. Consult the
NFPA for current standards. Review of your application
and future type of installation must be completed by
your local Fire Marshal or an Authorized Fire Department
Official prior to the installation of any equipment for this
purpose.
This Standard combines the following previous Standards
into one Standard: NFPA 480, NFPA 481, NFPA 482, NFPA
485 and NFPA 651. NFPA 484 was approved as an
American National Standard on July 19, 2002.
We have reviewed the latest NFPA Standard 484 for
“Combustible Metals, Metal Powders, and Metal Dusts, 2002
Edition” and we have determined:

length is inside the hose. Tighten the hose clamp
around the hose and connector.
For “HB” Hanging Bags (Figure 3), proceed with Step
2. DO NOT use “HB” Bags on Models 50S & 75S.
For “DB” Drum Bags (Figure 4) proceed to Step 5 on
Page 6.
2. “HB” type Hanging Bags are only recommended
when there is not enough floor space for a second
55 gallon drum next to the dust collector. However,
they are more cumbersome to empty and require
emptying much more often. A “DB” type bag will be
much easier to empty and will not require being
emptied as often.
a. Assembly of the “J” hooks (2) onto the angle iron
ring (1).
Thread a 1/4-20 nut all the way onto a “J” hook.
Install a 1/4” flat washer. Put threaded end of the
“J” hook nut and washer assembly through a hole
in the angle iron ring. Install a second washer on
top of the ring hole. Install a second 1/4-20 nut
on top of the flat washer and tighten. Repeat
these steps for each “J” hook.
3. a. Slide a hose clamp (4) over the inlet collar in the
side of the HB dust bag (3).
b. Slide the inlet collar of the dust bag over the
exposed end of the hose/bag connector (5) that
you connected in Step C-1,d above.
c. Secure the dust bag collar to the hose connector
with the hose clamp.
4. This step will be performed much more safely
with two people on separate ladders.
a. Put one bag grommet over each “J” hook in the
ring/hook assembly.
b. Carefully start climbing the ladders while holding
onto the ring/bag/hose assembly.
c. Raise the ring/bag/hose assembly high enough
above the ground without putting to much tension
on the bag or the hose entering the side of the
bag. Also make sure the hose (6) is not “kinked”
at the discharge of the dust collector. This is the
proper height for the ring to hang off of the
ground.
d. Measure the distance from the ring to the ceiling
joist, rafter or truss.
e. Securely hang the ring from a ceiling joist, rafter
or truss with approved cable or chains.
f. The bag should be hanging so it doesn’t
touch the floor AND it doesn’t pull on the
dust collector discharge hose. See Figure 3
on page 14.
IV. ASSEMBLY (Continued)
The intake cylinder/guard (#19) in Step 1b below, MUST
be installed. Failure to install this part will GREATLY
reduce the airflow (CFM) of the dust collector.
NOTE

6
NOTE:
Never let an HB type hanging bag collect over 12” of dust or
chips in the bottom of the bag. When dust or chips reach a
depth of 12”, the bag must be emptied. If not, the weight of the
material inside the bag may cause the bag to tear from the
grommet straps at the top or at the zipper in the bottom.
See Dust Bag Cleaning Instructions on page 11.
For “DB” Drum Bags (Figure 4) proceed with Step 5.
5. The “DB” type Drum Mount dust bags come in
three sizes. Approximate dimensions are:
DB24x40 is 24” diameter x 36” high for models 50S
and 75S. Available in two fabric types.
DB24x80 is 24” diameter x 72” high for models
100S, 150S, 200S and 300S. Available in three
fabric types.
DB48x80 is 48” diameter x 72” high for models
100S, 150S, 200S and 300S. Available in three
fabric types.
a. You should have completed Steps C-1,a through
C-1,d on page 5.
b. Slide a hose clamp (9) over the inlet collar in the
side of the dust bag.
c. Slide the inlet collar of the dust bag (7) over the
exposed end of the hose connector (8) that you
installed in Step C-1,d on page 5. Secure the
dust bag collar to the hose connector by
tightening the hose clamp.
d. The “DB” type Drum Mount dust bag has an
outer and an inner sleeve in the bottom opening
of the bag. There is also a belt on the outside of
the bag. Loosen the belt as far as possible.
e. Roll back the outer sleeve and slide the inner
sleeve inside an open top 55 gallon drum. Now,
unroll the outer sleeve down over the outside of
the drum so that the bottom of the bag overlaps
the top of the drum by 4-6”. Tighten the belt as
tight as possible
NOTE:
If you will be collecting dust smaller than 10
microns, we recommend you remove the belt
from the bag and install a 55 gallon drum lid
clamp around the top of the drum. This will
provide a better seal between the drum and the
dust bag.
f. There is a single grommet in the top, center of
the bag. Connect one end of a rope or cable
through the eye of the grommet and connect the
other end to a rafter or truss in the ceiling. This is
only needed to hold the bag up when the dust
collector is turned off. Leave about 12” of slack
in the rope or cable.
V. INSTALLATION
A. Proper Cans, Drums and Unit Location
Models 33S, 50S and 75S should be mounted on top of a
25-30 gallon garbage can or a 30-35 gallon drum. The
garbage can or drum should have a diameter no less than
18” and not more than 20”. Do not use plastic cans or
drums. A fiber can or drum may be used if it has a fire
resistant foil liner and it can support the weight of the dust
collector.
Models 100S, 150S, 200S and 300S should be mounted
on top of a 55 gallon, roll-top, steel drum only. The drum
should have a diameter no less than 22” and not more than
24”. Do not use plastic or fiber drums. Place the
assembled dust collector as near as possible to the dust
generating source.
IV. ASSEMBLY (Continued)

(2) CFM's required are minimums per each equipment type. Duct
velocity should not be less than 3500 FPM to prevent wood dust
from settling in duct work.
(3) Requires 2 nozzles or hoods. CFM’s shown are total CFM for
both nozzles or hoods.
(4) For all metalworking applications, duct velocity should be at least
3500 FPM for light grinding or buffing and at least 4500 FPM for
heavy grinding or buffing to prevent settling in duct work.
(5) The wheel hood should cover at least 75% of the wheel to be
considered a good enclosure.

How To Select The Proper Size Dust-Master Dust Collector
Although Cincinnati Fan Dust-Master dust collectors will give you
excellent results in collecting wood chips, fine dust and metal shavings,
they are not designed to work in large central system applications. These
are portable units that can be moved from machine to machine. To select
the proper size Dust-Master, use the criteria below:
1. Add the “CFM REQUIRED” for each machine per the above chart. This
is your TOTAL CFM REQUIRED.
2. Now, select the Dust-Master model from page 1 with a “Max. CFM”
greater than your TOTAL CFM REQUIRED in Step 1. If none of the
models on page 1 have a Max. CFM greater than your TOTAL CFM
required, you will need more than one unit.
3. If the unit will be in a “fixed installation” all ductwork should be sheet
metal duct instead of flexible hose. The pressure drop through flexible
hose can be 2-3 times that of smooth wall pipe. DO NOT use any PVC
or plastic pipe. It can deliver a severe static electric shock caused
by high velocity dust passing through it.
4. The Dust-Master should be located as close to the machine as possible
and preferably no more than 10 feet away.
5. Use as few elbows as possible in your ductwork. The loss through one,
90° elbow is equal to approximately 10 feet of straight, smooth wall pipe.
6. If the dust collector will be used for more than one machine, install slide
gate dampers in the duct at each machine to “close off” that section of
duct when using another machine. This will allow the dust collector to pull
from only one machine at a time and thus increase the dust collector
performance.
7. Typically, a Model 150S will work with up to 20 total feet of duct, a model
200S will work with up to 30 total feet of duct work and a 300S will work
with up to 75 total feet of duct. These values are based on having
dampers at each machine connection (as in note 6 above) and all duct
work is smooth wall, sheet metal.
Abbreviations used in charts:
CFM = Cubic feet of air per minute
FPM = Feet per minute
sf/m = Surface feet per minute
Also see Section C on Page 8.
7
B. Exhaust Volumes Required for Different Applications (1)

C. Duct Work Recommendations
The maximum CFM rating for each model dust collector
should be greater than the minimum required CFM as
listed in the Exhaust Volumes equired for Different
Applications chart on page 7.
If you will be connecting the dust collector into a piping
system for more than one machine, the dust collectors
maximum CFM should be greater than the minimum CFM
required for each machine in the system. If the piping
system will have slide gate dampers at each machine, with
only one machine operating at a time, then the dust
collector can handle more machines as long as the CFM
required does not exceed the maximum CFM of the dust
collector. As a rule of thumb, one dust collector can handle
multiple machines as follows:
Model 33S & 50S .. One machine only.
Model 75S ...........Two machines if within 5 feet of each other.
Model 100S .........Two machines if within 10 feet of each other.
Model 150S .........Two machines if within 20 feet of each other.
Model 200S .........Up to 30 feet of 5” duct, and 3 machines.
Model 300S .........Up to 75 feet of 5” duct, and 3-4 machines.
NOTE:
The number of machines you can collect from will depend on
the CFM required per machine.
General Recommendations for Ductwork Systems:
1. The National Fire Protection Agency (NFPA) will no
longer permit a single dust collector to be used to
collect BOTH wood dust or chips AND metal dust or
chips because of the possibility of a fire and/or
explosion.
2. DO NOT use any PVC pipe or flexible hose for
duct work. This is no longer permitted by the
National Fire Protection Agency (NFPA). Dust
traveling through PVC pipe or hose can build up a
static electric charge.
3. Limit the use of flexible hose in any duct work to as
little as possible. The pressure drop (resistance)
through flex hose can be 2-3 times greater than
smooth wall sheet metal pipe.
4. If connecting a dust collector to more than one
machine, you should install slide gate dampers at
each machine so the dust collector is only pulling
from one machine at a time.
5. eep the number of duct elbows to a minimum. A
90° elbow has the same pressure drop (resistance)
as 10 feet of straight pipe.
6. Estimate 2 CFM reduction in air flow for each foot of
straight pipe and 20 CFM reduction for each 90°
elbow.
7. Pneumatic conveying of wood dust requires a
minimum air velocity of 3500 feet per minute (FPM)
in the duct or hose. For metal dust, the velocity can
be from 3500 FPM to 4500 FPM. Velocities less than
these will allow the dust to settle in the duct work or
hose. Therefore, the CFM must not be reduced
below these velocities.
8. Connect the dust collector inlet hose to the
connector port built into the dust producing machine.
If there is no port on the machine, place the inlet
hose and inlet nozzle as close as safely possible
where it will collect the most dust.
9. DO NOT use any duct or hose smaller than 3”.
D. Electrical
All electrical connections and wiring must be
performed by qualified personnel or a licensed
electrician. Models 33S, 50S, 75S and 100S, with single
phase, TEFC motors are pre-wired at the factory with a
cord, plug and switch to operate on a 115 Volt, 1 Phase, 60
Hertz power supply. These motors are also connected for
the proper blower wheel rotation.
All other motors must be wired by the user for the
operating voltage as stated on the motor nameplate and
wiring diagram. All wiring must be in accordance with
Underwriters Laboratories (UL) and the National
Electric Code (NEC). After all wiring is properly
completed, apply power to the motor for 1-2 seconds and
then turn it off. As the motor slows down, observe the
rotation of the motor cooling fan on top of the motor. The
proper rotation for all dust collector motors is Clockwise
(CW) when looking down on top of the motor. If the motor
is turning Counter-Clockwise (CCW), lock out the power to
the motor and then make the wiring changes per the motor
wiring diagram either on the motor nameplate or inside the
motor conduit box.
VI. OPERATION
The only operation steps that need to be monitored are
emptying the can or drum and the dust bag. The can or
drum should never be allowed to become over 1/3 full. The
bag should never be more than 1/4 full.

HAZARDOUS VOLTAGE CAN CAUSE ELECTRICAL
SHOC AND DEATH.
Always disconnect or lock out power to the motor and let
the wheel come to a complete stop BEFORE attempting
any inspection, service, maintenance or
moving of this dust collector.
HIGH SPEED ROTATING EQUIPMENT CAN CAUSE
SEVERE PERSONAL INJURY.
There is a high speed blower wheel inside the blower
housing and another one inside the fan cover on top of the
motor. Always disconnect or lock out power to the motor
and let the wheel come to a complete stop BEFORE
attempting any inspection, service, maintenance or moving
of this dust collector.
WEAR EYE PROTECTION.
Always wear eye protection when operating, servicing or
cleaning this dust collector with a high pressure air hose.
A. Motor
The bearings in the motor are lubricated and sealed for life so
they will not require any additional lubrication during the life of
the motor. eep the motor clean as excessive dirt may prevent
proper cooling of the motor. Use no more than 40 PSI air to
blow off excessive dirt.
B. Blower Wheel and Steel Components
The cast aluminum wheel and steel components are generally
maintenance free during the life of the unit. It is possible that
very fine, sticky dust particles can build up on the blades and
back plate of the blower wheel. When the unit is lifted off of the
can or drum for emptying of the can or drum, you should also
inspect the blower wheel for any material buildup. Using a
flashlight, look into the blower inlet underneath the lid. Any
material that has built up on the wheel must be removed to
prevent the wheel from an imbalance situation that could
cause a premature motor bearing failure and/or dangerous
wheel failure. For proper cleaning instructions, see the
following section.
C. Cleaning the Blower Wheel
This operation is best performed with the dust
collector sitting on top of the can or drum.
1. Lock out and disconnect power to the motor.
2. Disconnect the discharge bag elbow (8) from the
blower housing discharge. On units with oversized
dust bags, disconnect the flex hose from the blower
discharge.
3. There are two pop rivets that connect the discharge
guard (5) to the top section of the blower housing
discharge (4). These pop rivets should be drilled out
with a 3/16” drill bit.
4. Using a 7/16“ socket and wrench, loosen and
remove all the 1/4-20 nuts & bolts holding the two
housing halves (4and 7) together around the blower
housing flange.
5. After removing all the nuts and bolts, use a screw
driver or pry bar to carefully break the sealant in
between the two housing halves.
6. After the sealant is loosened, lift the motor side
housing (4) and motor assembly off of the inlet side
housing (7).
7. Set the blower housing/wheel/motor assembly on a
work bench resting on the side of the motor.
8. If possible, clean the blower wheel (6) with a wire
brush while the wheel is still on the motor shaft. Use
an air hose to blow off the wheel when finished. If it
is not possible to clean the wheel while on the motor
shaft, see Section D. eplacing The Blower
Wheel below.
9. If cleaning the blower wheel while on the motor shaft
was successful, use a putty knife to clean the
excess sealant caulk off of the flanges of both
blower housing halves (4and 7).
10. Apply a fresh bead of silicone sealant to the housing
flange on the blower housing inlet side (7).
11. Carefully reset the blower housing motor side (4) on
top of the blower housing inlet side (7) so that the
outside of the flanges and the discharges line up.
12. Reverse Steps 5 through 1, at left, to complete
reassembly.
D. Replacing the Blower Wheel
This operation is best performed with the dust
collector sitting on top of the can or drum.
1. First complete Steps 1 through 7 for Step C.
Cleaning the Blower Wheel, at left.
2. Now, follow the following steps to replace the blower
wheel.
3. Measure the distance from the front of the wheel
hub to the end of the motor shaft. eep this
dimension.
4. There are two set screws in the blower wheel. Using
a 5/32” Allen wrench, remove the two set screws
from the wheel hub.
5. Using two pry bars, place the pry bars behind the
back plate of the wheel so that the pry bars are
located behind two opposite wheel blades. This will
give you the most leverage. Pry the wheel off of the
motor shaft being careful not to damage or distort
the blower housing.
6. After removing the wheel, clean it thoroughly with a
wire brush if you will be reusing it.
7. If the wheel is eroded, DO NOT reuse it. It will be
out of balance and will damage the motor bearings.
8. If you can reuse the wheel, you MUST replace the
set screws in the wheel hub. Set screws can never
VII. MAINTENANCE
9

be used more than once. Replace them with 5/16-
18 set screws with a knurled head and a nylon
locking patch on the side of the screw.
9. File any burrs on the motor shaft from the previous
set screws and dress up the keyway in the motor
shaft with a file.
10. Using a rubber or raw hide hammer, reinstall the
present wheel or install a new wheel onto the motor
shaft. Locate the wheel hub on the motor shaft to the
same dimension you took in Step 3 on page 9.
DO NOT use a steel hammer. It can damage the
wheel and/or the motor bearings.
11. Line up the keyway in the motor shaft with the keyway
in the wheel hub.
12. Install a new 3/16” square shaft key into the keyway.
The key should be no longer than 1-1/2”. The key
should be positioned so it is flush with the end of the
wheel hub.
13. Spin the wheel by hand to make sure it is not rubbing
against the motor side of the blower housing.
14. Tighten the set screw over the shaft key first. Then
tighten the set screw onto the motor shaft. Both
screws should be tightened to 165 inch pounds.
15. Use a putty knife to clean the excess sealant caulk off
of the flanges on both blower housing halves.
16. Apply a fresh bead of silicone sealant to the housing
flange on the blower housing inlet side (7).
17. Carefully reset the blower housing motor side (4) on
top of the blower housing inlet side (7) so that the
outside of the flanges and the discharges line up.
18. Look into the discharge to make sure the blower
wheel is not touching the inlet side of the blower
housing.
19. Reverse Steps 5 through 1, on page 9 to complete
reassembly.
E. Replacing the Motor
Before you attempt to replace the motor, make sure you have
the correct replacement motor in your possession. All dust
collector motors have the following characteristics:
a. All Models 33S through 200S have a 56C frame
with a C-Face mounting and a 5/8” shaft.
b. Model 300S has a 145TC frame with a C-Face
mounting and a 7/8” shaft.
c. All motors used in the U.S.A. and Canada are
3450 RPM.
d. All motors are Totally Enclosed (TEFC) or
Explosion Proof (EXP). NEVER replace an EXP
motor with a TEFC motor.
e. The motor horsepower (HP) should match the HP
of the motor you are replacing
f. Make sure the new motor matches the operating
voltage, phase and hertz of the old motor.
To replace the motor, follow Steps 1 through 8.
This operation is best performed with the dust collector
sitting on top of the can or drum.
1. First complete Steps 1 through 7 for Cleaning the
Blower Wheel, on page 9.
2. Now, complete Steps 3 through 8 for Replacing the
Blower Wheel, on page 9-10.
3. Before removing the motor, notice the location of the
motor conduit box with relation to the blower
housing.
4. With a 9/16” socket wrench, remove the four 3/8-
16UNC bolts that hold the motor onto the motor side
blower housing (4).
5. Remove the old motor.
6. Install the new motor onto the blower housing with
the conduit box in the same orientation as noticed in
Step 3 above.
7. Replace or reinstall the four motor bolts and lock
washers through the blower housing and into the
four holes in the motor C-Face. Thread all bolts by
hand and then tighten them with the socket wrench.
8. Follow Steps 10 through 19 for Replacing the
Blower Wheel, at left, to complete the reassembly
of the dust collector.
F. Emptying the Can or Drum
NEVE ATTEMPT TO EMPTY A CAN O
D UM WHILE THE UNIT IS OPE ATING.
Empty the dust collector can or drum when it becomes 1/3
full. If the can or drum becomes too full, it will reduce the
suction of the dust collector.
G. Emptying the Dust Bag
NEVE ATTEMPT TO EMPTY A DUST
BAG WHILE THE UNIT IS OPE ATING.
If you are collecting heavier chips, they will settle in the
can or drum. Finer, lighter dust will go on into the dust bag.
Therefore, the dust bag must also be emptied. The
National Fire Protection Association (NFPA) states in their
Standard 664, that wood dust in dust bags MUST be
emptied “every day or less if warranted.” They should
then be checked for holes, rips or loose seams that could
leak. Emptying of the dust bag should only be performed
by trained personnel wearing the proper clothing and the
proper respiration equipment. How often you should empty
the dust bag is really a judgment call. It will vary with the
weight of the material you are collecting. No matter what
you are collecting, NEVER let the bag get more than 1/4
full. The major cause of having to replace dust bags is
due to ripping because of too much weight in the
bottom of the bag.
H. Cleaning the Dust Bag
NEVE ATTEMPT TO OPE ATE A DUST COLLECTO
WITHOUT THE DUST BAG IN PLACE.
WARNING:
If dust collector has been used to collect ANY materials
included in the following list, it should NOT be cleaned. The
dust bag must be disposed of using approved methods and
procedures as adopted by the proper regulatory agency or
agencies.
A. Any carcinogenic or biological materials.
B. Any flammable materials.
C. Any explosive materials.
D. Any water reactive materials.
E. Any nuclear materials.
10

F. Any materials with cleaning instructions that are in
contradiction with the following cleaning instructions.
G. Any materials considered to be unsafe if they come
in contact with the body.
Cleaning Instructions
Acrylic Coated Polyester Felt, Teflon® Coated Polyester
Felt or Nomex® Felt Dust Bags:
Because of the special coatings that have been applied to
these materials, we do not recommend that these bag types be
cleaned. They should be replaced when necessary or at least
annually.
Cotton Sateen & nit Polyester Dust Bags:
1. Inspect dust bag for holes. If any holes are found the
bag must be replaced.
2. Unzip any zipper in the bag.
3. Turn bag inside out.
11
4. Shake bag well to dislodge any material sticking to
the pores of the bag.
5. Lay bag flat on table or floor.
6. Vacuum bag on both sides.
7. Put bag in washer.
8. Set washer for Gentle cycle.
9. Set water temperatures to COLD for wash and rinse
cycles.
10. Add 1/4 cup of Woolite® detergent.
11. After washing is completed, hang bag on line to dry.
DO NOT put in dryer.
12. After bag has dried, turn it right side in.
13. Do not use dust bag until it has thoroughly dried.
NOTICE: Overwashing, harsh detergents and/or drying too
fast will cause bag to shrink and the inlet collar might
become too small to fit back onto the unit. Shrinkage is a
non-warranty claim. Dust bags can typically only be
washed one time.
