Safety Practices for Air Moving Devices.”
Improper operation of dust collectors and/or dust control systems may contribute to conditions in a work area or
facility which could result in severe personal injury, and product or property damage. All dust collection equipment
should be used only for its intended purpose and should be properly selected and sized for its intended use.
Process owners have important responsibilities relating to identifying and addressing potential hazards in their
processes. When the potential for handling combustible dust exists within a process the process owner should
include combustion hazards in their risk management activities and should comply with applicable codes and
standards related to combustible dust.
Electrical installation must be performed by a qualied electrician.
This equipment is not designed to support site ducts, piping, or electrical services. All ducts, piping, or electrical
services must be adequately supported to prevent injury and/or property damage.
Site selection must account for wind, seismic zone, and other load conditions.
Equipment may reach peak sound pressure levels above 80 dB (A). Noise levels should be considered when
selecting collector location.
Most dusts present safety and health hazards that require precautions. Wear eye, respiratory, head and other
protection equipment suitable for the type of dust.
Some components may be heavier than they appear. Use appropriate lifting methods to avoid personal injury and/or
property damage.
1 Safety Communication

Combustible Dust Hazards
Among other considerations, the current NFPA standards require owners whose processes involve potentially combustible
materials to have a current Dust Hazard Analysis, which can serve as the foundation for their process hazard mitigation strategy.
Mitigation may include but is not limited to:
• Prevention of all ignition sources from entering any dust collection equipment.
• Selection and implementation of re and explosion mitigation, suppression, and isolation strategies appropriate for the
risks in their process.
• Development and use of work practices to maintain safe operating conditions, and to ensure combustible dust does not
accumulate within their plant or process equipment.
Donaldson designs, manufactures, and sells industrial air ltration products for a wide variety of applications. Some applications
may include processes or materials with inherent re and explosion hazards. Donaldson is neither an expert nor a certied
consultant in re, spark, or explosion detection, suppression, or control. Donaldson does not provide engineering consulting
services related to process or dust hazard analyses, or code and standard compliance. Complying with applicable codes and
standards and managing the risks associated with the process or materials remains the responsibility of the process owner/
operator. Donaldson may provide referrals to consultants, suppliers of equipment or services related to the detection and/
or mitigation of sparks, res and/or explosions, but Donaldson does not assume responsibility for any such referrals, nor does
Donaldson assume any liability for the tness of a mitigation strategy or product for a particular installation or application. The
process owner’s nal selection of dust collectors and risk mitigation strategies should be based on the outcome of a Dust Hazard /
Process Hazard Analysis performed by the process owner. Although early engagement of a dust collector supplier provides helpful
insights on the availability and features of various products, process owners should consult with a combustible dust expert and/or a
process safety expert before making actual product and mitigation strategy selections.
Donaldson recommends that all industrial air ltration system designs be reviewed and approved by an expert consultant who is
responsible for the integrity of the system design and compliance with applicable codes and standards. It is the process owner’s
responsibility to understand the risks in their process and mitigate those risks in accordance with all applicable laws, regulations
and standards, including those published by the NFPA. Donaldson also recommends that proper maintenance and housekeeping
procedures and work practices be evaluated, developed, and followed to maintain any industrial air ltration products in safe
operating condition.
Many factors beyond the control of Donaldson can affect the use and performance of Donaldson products in a particular
application, including the conditions under which the product is used. Since these factors are uniquely within the user’s knowledge
and control, it is essential the user evaluate the Donaldson products to determine whether the product is t for the particular
purpose and suitable for the user’s application. All products, product specications, and data (airow, capacity, dimensions, or
availability) are subject to change without notice, and may vary by region or country.

Donaldson Company, Inc.
Torit Radial Blade (TRB) Fans provide a convenient, cost-effective method of integrating a fan with a Donaldson®Torit® dust
collector. The TRB mounts directly to the clean-air outlet of the dust collector, eliminating costly transition ducts, and reducing the
footprint of the system.
The TRB Fans feature a radial blade fan wheel which provides high static pressure. It also has direct drive operation to eliminate
maintenance of fan bearings and belts. TRB Fans have computer balanced fan and motor assemblies to ensure vibration-free
operation. When mounted to a Donaldson Torit Dust collector, the fan is designed to pull dusty air through the collector to be
ltered. Cleaned air then exits the collector via the outlet of the TRB Fan.
2 Product Description
Electrical work during installation, service or maintenance must be performed by a qualied electrician and comply
with all applicable national and local codes.
Turn all power off and lock out all power before performing service or maintenance work.
Check that the collector is clear and free of all debris before starting.
Do not install in classied hazardous atmospheres without an enclosure rated for the application.
3 Operation
The use of a damper or variable frequency drive (VFD) is required to control airow through the collector.
Lack of a control damper or VFD will shorten lter life.
When a variable frequency drive (VFD) is used to control fan operation precautions should be taken to eliminate or reduce any
shaft currents which may be imposed on the motor by the VFD as stated per NEMA Mg-1. Part 31.

LOCK-OUT all energy sources prior to performing any service or maintenance on the equipment.
Electrical service or maintenance work must be performed by a qualied electrician and comply with all applicable
national and local codes.
Rotating blades can cause serious injury. Operate equipment only when all guards are correctly and securely in
place.
Turn all power off and lock out all power before performing service or maintenance work. It is not unusual for the
equipment to be operated from a remote location, so equipment may start or stop unexpectedly.
4 Product Service
Donaldson Torit TRB fans are manufactured to high standards with quality materials and components. Proper maintenance will
ensure a long and trouble-free service life.
The key to good fan maintenance is regular and systematic inspection of all fan parts. Inspection frequency is determined by the
severity of the application and local conditions. Strict adherence to an inspection schedule is essential.
Regular fan maintenance should include the following:
Check the fan wheel for any wear or corrosion, as either can cause catastrophic failures. Check also for
the build-up of material which could cause unbalance resulting in vibration, bearing wear and serious
safety hazards. Clean or replace the wheel as required.
Lubricate the bearings, but do not over lubricate.
Periodically inspect the shaft for dirt buildup, corrosion and signs of excess stress or fatigue.
During any routine maintenance, all setscrews and bolts should be checked for tightness. See Torque
Value Table.
Specically for side mounted fans (motor horizontal) conrm the motor drain hole will be oriented facing down in the fan installed
orientation. If the motor orientation in the TBI fan as-received condition will not have the motor drain hole facing down when
installed in the desired side orientation (i.e. forward blast, up blast, aft blast) then:
1. Unbolt the drive plate (with the fan wheel and motor still attached).
2. Rotate the fan wheel/motor/drive plate assembly on the fan case such that the motor drain hole will face downward when the
fan is installed in the desired side mount orientation.
3. Re-bolt the fan wheel/motor/drive plate assembly to the fan case.
Note that the fan wheel should remain attached to the motor shaft and the motor should remain bolted to the drive plate and the
wheel/motor/drive plate assembly should be rotated as a single assembly.
When the fan is mounted to the collector in the desired side mount orientation conrm that the motor drain hole is facing
downward.
Failure to position the motor drain hole facing downward in the installed fan position may result in damage
to the motor.

Motor Maintenance
TRB Fans typically use motors with sealed bearings that are permanently lubricated for the life of the motor, but other types of
motors may have been selected for your fan.
ExxonMobil Polyrex™ EM is a trademark of Exxon Mobil Corporation
Vibration
The fan blower wheel should be periodically checked for material build-up and/or erosion. If material has built up on
any parts of the wheel, it must be removed and cleaned before it is put back into service.
If any parts of the wheel have been eroded, the wheel must be replaced. Failure to perform this inspection can cause
excessive vibration that will damage the fan blower and/or motor bearings. When vibration becomes excessive, it will
lead to complete fan blower failure that can result in severe personal injury and/or property damage.
The user must determine the frequency of this inspection based on the actual circumstances of their operation, but
check the vibration readings should never exceed a 12 month period.
The fan blower was balanced at the factory to comply with ANSI/AMCA Standard 204-05, Category BV-2. However, rough handling
in shipment and/or erection, weak and/or non-rigid foundations and misalignment may cause a vibration problem after installation.
After installation, the vibration levels should be checked by personnel experienced with vibration analysis and vibration analysis
equipment.
Note: The fan blower should not be operated if the vibration velocity of the fan exceeds 0.50 inches per second, lter out,
with the blower rigidly mounted.
Vibration readings for direct driven fan blowers should be taken on the motor at the top, sides, and end.
Grease Motors
Use the following steps for greaseable motors only:
1. Inspect the motor at approximately every 500 hours of operation or every 3 months, whichever occurs rst.
2. Keep the motor clean and the ventilation openings clear. If the motor is not properly ventilated overheating can occur.
3. Use an electrical insulation tester to periodically ensure that the integrity of the winding insulation has been maintained.
Investigate any signicant drop in resistance.
4. Grease the motor bearings using a high grade bearing grease. For standard service conditions ExxonMobil Polyrex™ EM
grease is recommended.
Under standard conditions, grease every 5,500 hours. In severe dirt and abrasive dust conditions, grease every 2750 hours.
Under extreme conditions, such as an environment with iron dust, grease every 550 hours.
Wheel Balance
Airstreams containing particulate or chemicals can cause abrasion or corrosion of the fan parts. This is often uneven and can lead
to wheel imbalance over time. When such wear is discovered, a decision must be made to rebalance or replace the wheel.
The soundness of all parts should be determined making sure there is no hidden structural damage. The airstream components
should also be cleaned to remove any build-up of foreign material. Specialized equipment can be used to rebalance a cleaned
wheel that is considered structurally sound.
Balance weights should be rigidly attached at a point that will not interfere with the housing nor disrupt airow.

Start-up / Commissioning
1. If possible, carefully spin the fan blower wheel by hand to ensure it rotates freely and no rubbing or clicking noise is heard.
2. Check that all fan blower mounting ange and duct work hardware is tight.
3. Check all fan blower wheel set screws are tight per Torque Values table found in this manual.
4. Ensure any inspection doors in the duct work are securely bolted or locked.
5. Ensure all electrical power components are properly sized and matched for electrical system.
6. Check that all required guards are properly secured.
7. If fan blower is mounted on an elevated support structure, make sure the structure is welded at all joint connections and the
structure is properly braced to prevent “side sway”.
8. Close any dampers to minimize load on motor, especially on fans with high temperature construction. Never subject a “cold”
fan to a “hot” gas stream. If the fan motor will be handling “hot gasses” greater than 150°F (65°C) it is imperative that the fan
motor be subjected to a gradual rate of temperature increase, not to exceed 15°F/minute (8°C/minute). The same temperature
limits are also important when the fan motor is experiencing a drop in temperature until the temperature drops down to 150°F
(65°C). Only when the entire fan motor has reached an equilibrium temperature of 150°F (65°C) or less, should the power be
turned OFF.
9. Ensure the power source connections to the fan motor are per the motor manufacturer’s instructions.
10. Ensure the fan motor wheel is stationary prior to start-up. Starting a fan motor with a wheel that is rotating backwards can
cause wheel damage.
Do not look into fan outlet to determine rotation. View the fan rotation through the back of the motor.
Check that the exhaust plenum is free of tools or debris before checking blower/fan rotation.
