SAFETY RULES
Follow all electrical and safety codes as well as the National Electrical Code (NEC), National Fire Protection Association (NFPA),
and the Occupational Safety and Health Act (OSHA). Qualified personnel should perform all electrical connections and wiring only.
National Fire Protection Association (NFPA) standards require specific duct design and dust collector configuration when collecting
potentially reactive metal dusts, such as aluminum, magnesium, and other materials. NFPA also covers other dusts such as grain
and plastics, etc. A guideline for determining the precautions to be taken can be found in NFPA 497. Other NFPA standards may
apply to your specific application. Consult current NFPA standards, available for NFPA, 1 Batterymarch Park, Quincy, MA, 02269,
800-344-3555, for applicable safeguards which may be required for the Installation, Operation, and Service of this product.
Additional references are the Uniform Building Code and the Uniform Mechanical Code.

improper methods, structural failure or inadequate supports.
WARNING
1. Avoid mixing combustible materials such as (but not limited to) buffing lint, paper / wood dust, aluminum or magnesium
with dust generated from the grinding of ferrous materials. This creates a potential for fire due to the mixing of sparks
and combustible materials.
2. Under no conditions should the machine operator be allowed to put lit cigarettes or any burning object into this or any
dust/mist control system.
3. Installation of this unit in applications where there is a chance for heated and/or flammable materials to enter the unit
should be evaluated to determine if a fire protection/extinguishing system should be installed. Federal, state or local
codes, a required by organizations such as NFPA and Factory Mutual Insurance or your insurance carrier may require
such a system. Air Cleaning Specialists, Inc. can offer basic guidelines for such an installation; however, final
installation design is the responsibility of the filtration unit
Owner/User.
4. Explosion relief vents are required on some applications. Consult with an insurance underwriter or an NFPA manual to
determine proper vent size ratio. Dust or mist collectors must be located outdoors unless otherwise indicated by NFPA
standards. Dust and mist collectors DO NOT CONTAIN EXPLOSION RELIEF VENTS as shipped from the factory and
must be field installed per NFPA standards.

SAFETY
READ AND SAVE THIS MANUAL COMPLETELY AND COMPLY AS DIRECTED. THIS MANUAL CONTAINS
PRECAUTIONARY STATEMENTS RELATING TO WORKER SAFETY. WORKERS HANDLING EQUIPMENT OR
SYSTEMS SHOULD BE INSTRUCTED TO CONDUCT THEMSELVES IN A SAFE MANNER. ALL THE POTENTIAL
HAZARD OF DUST AND MIST CONTROL SYSTEMS AND EQUIPMENT ARE IMPOSSIBLE TO LIST. THEREFORE,
OBTAIN THE SERVICES OF A PROFESSIONAL INSTALLER. A FIRE PROTECTION EXPERT SHOULD BE
OBTAINED IN THE EVENT THE PRODUCT IN INTENDED FOR USES, WHICH PRESENT A POTENTIAL RISK OF
FIRE OR FIRE PROPOGATION. REFER TO APPROPRIATE AUTHORITIES, AND DISCUSS YOUR INTENDED USE
WITH AIR CLEANING SPECIALISTS, INC.
Initial Inspection
If your new BLUE OX units were shipped in by truck you should inspect the carton for damages or possible shortages. If
there are any signs of possible shipping damages, unpack the units and make a note of the shortage or damage on the
freight bill before signing it. If the carton is opened at a later time and there is damage to the unit, you should file a
concealed damage claim with the delivery carrier. They are responsible for any damages in shipment or shortages that
were actually shipped.
Installing Your New Blue OX Units
All installations must meet all electrical or mechanical building codes that may apply in your particular area. If there are
no local requirements, you should follow the National requirements. If the optional Drain Plug was installed in your
unit, you can connect an appropriate 3/8” I.D. rubber hose for oil/mist routing.
All chains, hooks, bolts or other items used in the installation must be at least strong enough to support FOUR times the
weight of each unit. Unit weights are as follows:
BLUE OX2500D ..................................175 lbs.
BLUE OX2500D-CF .............................205 lbs.
BLUE OX2500D-CC .............................225 lbs.
BLUE OX2500D-HE .............................215 lbs.
BLUE OX2500D-WAL ..........................210 lbs.
BLUE OX2500D-WAR .........................210 lbs.
Methods for Mounting your OX2500D Unit
There are many different ways to install your units. The most common method of installing the units is to
support them from the ceiling structure with four chains. If the factory is going to utilize this method, you
should have 4 holes drilled down through the top of the unit approximately 6” from each end and 1” from each
side of the unit. The factory will then install Eye-Bolts that can be used to attached chain or rod. An eye bolt kit
is available at an additional cost.
Another available option is Strut Channel, which will be placed underneath the Blue OX and then hung with
appropriate steel chains and Q-Links.
The top end of the chains must be secured to the ceiling structure in a safe and acceptable manner.
The last typical method for installation is a duel L-Bracket mount, which is ideal for wall mounting.
The next page includes sketches indicating possible methods of mounting your OX2500D cabinets. Please ensure
all installations are secure and meet all local, state, and federal codes. Be sure your unit is connected to the
proper voltage and is protected by correct size fuses or breakers.

Blue Ox is a Product of Air Cleaning Specialists, Inc.
BLUE OX products are designed to improve your environment. The OX2500D series collects dust, smoke, oil mist,
oil smoke, and other atmospheric pollutants in industrial plants, shops, schools, and factories with high efficiency,
2 or 3 stage filtration. It is a complete air filter packaged unit that can be installed easily and used as a free
hanging air filter unit to clean the ambient pollutants, smoke and haze.
The OX2500D consists of a 4” pleated pre-filter that traps dust and larger particles. The second stage, micro-glass
multi-pocket bag filter has 98% arrestance and either 65 or 95% efficiency (depending on the application) on the
atmospheric dust spot test, removing smoke and other submicron size particles from the air. Changing out the
filters is easy as it requires no tools. The 4” pre-filter pulls from the unit and can be replaced. The main filter is
located directly behind the 4” pre-filter and pulls out also. For light odors, there is an optional 2” 50% bypass
carbon filter available.
MOTORS
All direct drive motors are protected with automatic restart overload protection.
All belt driven units must be protected externally.
OPERATION
Do not operate your units without filter for more than a few minutes at a time.
MAGNEHELIC PRESSURE GAGE OPTION
This is an option to help determine when to change the filters. As the bags fill with contaminants, the needle on
the gage will rise. We recommend changing the bags between 1.25 – 1.50 above the reading with clean filters. It is
normal to change the pleated twice (or more) as much as the inside bag filter. After the pleated has been change
and there is no longer a drop in pressure, then it is time to change main filter. The reading may vary depending
upon the contaminants. Please consult your Sales Engineer for further information.
FILTERS
All units are equipped with replaceable type media filters. In some cases, where contaminants being picked up are
dry, it is possible to blow the pre-filters and reuse them. Filters are available in a number of different degrees of
efficiencies. The filters in your new OX2500D unit have been selected by your representative to best collect your
particular type of contaminant.
Media type filters actually become more efficient as they load with contamination. However, as the filters load up,
the air flow volume will decrease and eventually will reach a point where they must be replaced to restore the
original air flow. Changing the filters in your new OX2500D air cleaner is easy. Old filters are simply pulled out of
the entrance end of the unit and new filters are installed. No tools are required. Turning the unit on when
installing new filters will help to pull them into place.
GENERAL NOTE: CLEANING AND INSPECTION OF CABINET
After the dirty components have been removed, inspect the cabinet interior. Remove foreign material, wipe
interior, and clean all filter seating surfaces.
When installing new filters the opening in the bag filter and the pre-filter should be in a vertical position. Be sure
the cloth part of the bag does not bunch up between the bag header and the angle iron filter stops on the cabinet.
The pre-filter should be installed with the wire mesh to the inside of the unit. Replacement filters can be supplied
by your representative.
LOUVERS
Four way lovers are provided on all units to permit you to direct the discharge air away from pilot lights or heaters
and to help you obtain the best air flow pattern for maximum cleaning.

Troubleshooting
Problem Remedy
Motor starts with a whine and does not
reach full speed.
If three-phase powered, stop motor
immediately. It may be “single phasing”
and will overheat, possibly damaging
internal windings. Check fuses and/or
wires for an interruption in one of the
lines. The motor may be operating on
two phases only.
Motor makes a scraping or knocking
noise.
Check motor cooling fan and its cover. It
may have been damaged or shifted in
transit and motor fan is rubbing. Check
for loose blower wheel on motor shaft –
tighten if necessary.
No suction or pressure, or some suction
but not as required (low or no airflow).
Check and open all dampers, if installed.
Check ducting for blockage, if installed.
Check for dirty or blocked filters (refer to
Maintenance section). Check rotation of
fan.
Excess vibration. Check structural support members.
Tighten all bolts on legs and cross
braces. Make sure entire structure is
solid. Check for loose blower wheel –
tighten if necessary.
Contaminants blowing through unit. Check for torn or damaged filters.
Check filter seals. If carbon module is
used, make sure filter sock in place.
Check door seals.
Motor over-amping nameplate. Access door open, close doors.
Incorrect filters or no filters in the unit.
Ductwork faulty.
