PORTABLE AIR CLEANER
MODEL 73-250
INSTRUCTION & MAINTENANCE MANUAL
CAUTION: This device is powered by rotating electrical machinery!! Careless or improper use may result in
personal injury. Read the Safety Precautions and Warnings contained within prior to operating this machine.
READ AND SAVE THESE INSTRUCTIONS.
SAFETY WARNINGS & CAUTIONS
FAILURE TO OBSERVE THE FOLLOWING
PRECAUTIONS COULD RESULT IN SERIOUS
INJURY, INCLUDING DEATH IN EXTREME
CASES. SAVE THESE INSTRUCTIONS.
WARNING: (EXPLOSION HAZARD)
This unit contains universal motors, which spark
during norma! operation. Do not use in areas
contaminated by volatile or flammable materials as
these sparks may ignite the contaminates and cause
a dangerous explosion.
WARNING: (HARMFUL FUMES)
The filters used in this unitwill remove solid
particulate ONLY, and do not eliminate fumes and
gases that may be a health hazard. Failure to
observe the presence of such fumes could cause
serious illness or death,
CAUTION: (SHOCK HAZARD)
To insure continued protection against shock
hazard, connect AC cord only to properly grounded
outlets. Replace defective cords immediately. Do
not expose to moisture or liquid as this could defeat
the electrical insulation thus causing electrical
shock.
CAUTION: (AIRFLOW BLOCKAGE)
Since exhaust air leaves the bottom of this unit,
caution should be observed not to set unit down in
such a way as to block the exhaust.
MISCELLANEOUS CAUTIONS:
1. Use of any attachment not recommended or
sold by the air cleaner manufacturer may result
in risk of fire, electric shock, or injury to persons.
To reduce the risk of damage to the electric plug
2.
or cord, disconnect by pulling plug rather than
cord when removing power from the air cleaner.
Make sure cord and hose are located so they
3.
will not be stepped on, tripped over, or otherwise
subjected to damage or stress.
An extension cord should not be used unless
4.
absolutely necessary. Use of improper
extension cord could result in risk of fire and
electric shock. If extension cord must be used,
use only a grounded cord and follow these
recommendations:
25 n.-#14AW6.
60 ft. -#12 AWG.
100 ft.-#10AWG.
CAUTION: (STRONG VACUUM)
Care must be taken to avoid personal injury by not
allowing hose inlet to contact any body area such as
eyes, ears, mouth, etc.
CAUTION: (LIFTING)
Although this unit weighs less than 40 lbs. with
filters, improper lifting or handling of this unit could
cause back injury. Follow the recommended
method for lifting.
Do not disassemble the air cleaner. Take it to a
5.
qualified serviceman when service or repair is
required, incorrect reassembly may result in risk
of electric shock or fire.
To reduce the risk of electric shock or bodily
6.
injury, unplug the air cleaner from outiet before
attempting any maintenance or cleaning.
Turning off the power switch will not eliminate
this risk.
THEORY OF OPERATION
This unit is a lightweight, portable air cleaner
employing two thermally protected, high
performance, flow through vacuum motors
producing very high velocity airflow through the unit.
By utilizing a large (2 ’/2") inlet plus a variety of
collecting nozzles and fittings, fine solid particulate
material and smoke may be removed from the air by
the filter media.
An initial spark trap collects large particles before
they reach the fitter. An easy to empty tray is
attached to the front cover to enable the removal of
the large particles collected by the spark trap without
removing the filter. This trap further isolates the filter
from sparks in the case of a welding operation.
A "clogged" filter light, actuated by a differential
pressure switch is an integral part of the unit. When
the filters become clogged, the light will illuminate.
At this point, the filter should be changed.
GENERAL MAINTENANCE
ONLY QUALIFIED SERVICE TECHNICIANS
SHOULD MAKE REPAIRS TO THIS UNIT.
3. Connect the unit to the power source and test
the operation of the unit by turning it ON with the
On/Off switch. Should the motors not start, or
should the machine make unusual noises,
immediately turn the machine off and seek
trained maintenance personnel. Once the test is
complete, turn the unit back OFF.
4. Attach the hose to the inlet.
5. Assemble the flexible metal hose and nozzle per
Figure #2.
6. Connect the hose/nozzle combination
assembled in Step 5 above to the machine with
the 10' flexible hose and the supplied coupling.
This completes the basic assembly of the unit.
Depending upon the accessories ordered and the
logistics of the work place, the installation
configuration may vary.
DO NOT REPLACE THESE MOTORS WITH
MOTORS OTHER THAN THOSE RECOMMENDED
BY THE MANUFACTURER.
UNPACKING
Carefully inspect the unit for concealed damage that
may have occurred during shipping and handling, if
any damage is found, immediately contact the
Freight Company. Make sure there are no dents in
the housing, as they might prevent the filter from
sliding into the unit smoothly. If there is no evidence
of damage, remove the end cover by releasing the
two rubber latches. Removal of the front cover will
allow inspection of the inside of the unit.
After unpacking the machine, check to see that the
following parts and accessories are present:
1) -10' Flexible Hose
1) - Coupling
1) - Flexible Metal Hose/Magnetic Base Component
Parts. (See Figure #2 For Individual Parts
Included)
1) - Slot Nozzle
1) - Filter
INSTALLATION (See Figure #1)
1. Insert the filter, gasket first, into the unit. Then
place the rubber then steel washers over the
threaded rod. Tighten the wing nut down so that
the filter is sealed and will not rotate.
2. Replace the front cover/spark trap assembly and
re-latch the cover using the rubber latches.

OPERATION
Your ACE Industrial Products machine is designed as a
source capture device, i.e., it is intended to eliminate
smoke and particulate at their point of origin. Keeping this
in mind, the machine should be operated in the following
manner:
Re-read the section on Safety Warnings & Cautions
before proceeding any further.
1. Place the machine on a flat, level surface. Pidt a
location that will allow unrestricted flow of the exhaust
air to the atmosphere.
2. For units with wheels or casters, lock the wheels or
block the wheels.
3. Place the collection nozzle as close to the work as
practical without interfering with the operator. Secure
the nozzle if necessary.
Figure 1
4. Using the ON/OFF switch, turn the machine on.
Should the motor not start, or should the machine
make unusual noises, immediately turn the machine
off and seek trained maintenance personnel. Do not
continue to use the unit.
5. Upon completion of the spedfic manufacturing or
welding operation, turn the machine off. Continuous
running of the unit will reduce the life of the filter and
the motor brushes as well as increase utility cost.
6. When the "clogged" filter light indicates that the filter
is dogged, turn the machine off and remove power
cord from its power source.
See the sedion on installation and use the reverse
process to remove the dirty filters. Re-install the new
filter and reconned the machine to its power source.
MAINTENANCE & REPLACEMENT PARTS
FILTERS: .
As previously slated in the "Theory of Operation section
of this manual, the "dogged" filter indicator light will light
whenever the differential pressure across the filter
indicates that the filter is dogged. When opening the unit,
there are no vacuum hoses to disconnect sin№ the
pressure sensing is accomplished by measuring at the
inlet and inside the suction chamber. The differential
pressure trip point is preset and is not field adjustable.
When the filter gets dirty, it needs to be replaced with a
new one or the filter can be cleaned. To dean, take the
filter out of the unit. Hold the filter 2 to 3 inches above a
concrete floor. Gently drop the filter, rotate and repeat until
most of the dirt falls out of the filter or the filter can be
vacuumed with a portable air vac (if needed, order 80-
201MD). To re-assemble, use reverse process to remove
filter and sweep up dirt that is on the floor.

PERFORMED ONLY BY QUALIFIED, TRAINED
TECHNICIANS.
1. Motor brushes are available from the factory by
ordering Part No. 65077. The use of high performance,
bail sleeve motors provide about 500 hours of brush
operation (depending upon filter condition). Brushes
should be periodically checked after 500 hours use and if
worn, replace as a matter or preventative maintenance.
2. Vacuum Motors are available from the factory by
ordering Part No. 65001. These motors are thermally
protected by an automatic reset thermal circuit breaker
and will shut down if they are overheated due to lack of
airflow or locked rotor condition.
DO NOT REPLACE THESE MOTORS WITH A MOTOR
THAT DOES NOT HAVE A THERMAL OVERLOAD!
