Donaldson Company, Inc.Safety CommunicationRotating blades can cause serious injury. Operate fan only when all guards are correctly and securely inplace.Turn power off and lock out all power before performing service or maintenance work. It is not unusual forthe fan to be operated from a remote location, so fans may start unexpectedly.Keep body, hands and foreign objects away from the inlet, the outlet and the other moving parts of the fan such asshafts, belts and pulleys.This fan has moving parts that can cause serious bodily injury. Before operating or starting maintenance, read theinstallation and maintenance instructions provided with this manual and AMCA Publication 410 “Recommended SafetyPractices for Air Moving Devices.”Combustible Dust HazardsAmong other considerations, the current NFPA standards require owners whose processes involve potentiallycombustible materials to have a current Dust Hazard Analysis, which can serve as the foundation for their processhazard 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 fire and explosion mitigation, suppression, and isolation strategiesappropriate for the risks in their process. Development and use of work practices to maintain safe operating conditions, and to ensure combustible dustdoes not accumulate within their plant or process equipment.Donaldson designs, manufactures, and sells industrial air filtration products for a wide variety of applications. Someapplications may include processes or materials with inherent fire and explosion hazards. Donaldson is neither anexpert nor a certified consultant in fire, spark, or explosion detection, suppression, or control. Donaldson does notprovide 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 materialsremains the responsibility of the process owner/operator. Donaldson may provide referrals to consultants, suppliersof equipment or services related to the detection and/or mitigation of sparks, fires and/or explosions, but Donaldsondoes not assume responsibility for any such referrals, nor does Donaldson assume any liability for the fitness of amitigation strategy or product for a particular installation or application. The process owner’s final selection of dustcollectors and risk mitigation strategies should be based on the outcome of a Dust Hazard / Process Hazard Analysisperformed by the process owner. Although early engagement of a dust collector supplier provides helpful insights onthe availability and features of various products, process owners should consult with a combustible dust expert and/ora process safety expert before making actual product and mitigation strategy selections.Donaldson recommends that all industrial air filtration system designs be reviewed and approved by an expertconsultant who is responsible for the integrity of the system design and compliance with applicable codes andstandards. It is the process owner’s responsibility to understand the risks in their process and mitigate those risks inaccordance with all applicable laws, regulations and standards, including those published by the NFPA. Donaldsonalso recommends that proper maintenance and housekeeping procedures and work practices be evaluated,developed, and followed to maintain any industrial air filtration products in safe operating condition.Many factors beyond the control of Donaldson can affect the use and performance of Donaldson products in aparticular application, including the conditions under which the product is used. Since these factors are uniquelywithin the user’s knowledge and control, it is essential the user evaluate the Donaldson products to determine whetherthe product is fit for the particular purpose and suitable for the user’s application. All products, product specifications,and data (airflow, capacity, dimensions, or availability) are subject to change without notice, and may vary by region orcountry.1

Torit Backward Inclined Fan, TBI-3 through 30DescriptionInspection on ArrivalTorit Backward Inclined (TBI) Fans provide a convenient,cost-effective method of integrating a high efficiency fanwith a Donaldson Torit dust collector. The TBI mountsdirectly to the clean-air outlet of the dust collector,eliminating costly transition ducts, and reducing thefootprint of the system.1. Inspect equipment and parts on deliveryOperation5. Compare equipment and parts received withdescription of product ordered.The TBI Fans feature a backward inclined fan wheelwhich provides high efficiency operation. It also hasdirect drive operation to eliminate maintenance of fanbearings and belts. TBI Fans have computer balancedfan and motor assemblies to ensure vibration-freeoperation. When mounted to a Donaldson Torit Dustcollector, the fan is designed to pull air through thecollector to be filtered. Cleaned air exits the collector viathe outlet of the TBI Fan.2. Report any damage to the delivery carrier.3. Request a written inspection report from the ClaimsInspector to substantiate any damage claim.4. File claims with the delivery carrier.6. Report incomplete shipments to the delivery carrierand your Donaldson Torit representative.7. Remove crates and shipping straps. Remove loosecomponents and accessory packages before liftingparts from truck.8. Check for hardware that may have loosened duringshipping.9. Use caution removing temporary covers.10. The fan and accessories should be inspected onreceipt for any shipping damage. Turn the wheel byhand to see that it rotates freely and does not bind. Ifdampers are provided, check for free operation of allmoving parts.2

Donaldson Company, Inc.Installation Codes and ProceduresCodes may regulate recirculatingfiltered air in your facility.Consult with the appropriate authoritieshaving jurisdiction to ensure compliancewith all national and local codes regardingrecirculating filtered air.Safe and efficient operation of the equipment dependson proper installation.Authorities with jurisdiction should be consultedbefore installing to verify local codes and installationprocedures. In the absence of such codes, installcollector according to the National Electric Code,NFPA No. 70-latest edition and NFPA 91 (NFPA 654 ifcombustible dust is present).A qualified installation and service agent must completeinstallation and service of this equipment.All shipping materials, including shipping covers,must be removed from the collector prior to or duringequipment installation.Failure to remove shippingmaterials from the equipment willcompromise performance.Inspect parts to ensure all hardware is properly installedand tight prior to operating equipment.3Hoisting InformationFailure to lift the fan correctly canresult in severe personal injuryand/or property damage.A crane or forklift and qualified operator arerecommended for unloading, assembly, andinstallation of the fan.Use all lifting points provided.Fans should be lifted by the base, mounting supports,or lifting points only. Never lift a fan by the wheel, shaft,motor, motor bracket, housing inlet, outlet, or any fan partnot designed for lifting.Use clevis connectors, not hooks, on lifting slings.Check the Specification Control drawing for weight anddimensions of the fan to ensure adequate crane capacity.Refer to applicable OSHA regulations and local codeswhen using cranes, forklifts, and other lifting equipment.Use drift pins to align holes in flanges during assembly.StorageCheck dampers for free operation and lubricatemoving parts prior to storage. Inspect the stored fanperiodically. Rotate the wheel by hand every two weeksto redistribute grease on motor bearing parts.

Torit Backward Inclined Fan, TBI-3 through 30Electrical WiringElectrical installation, service,or maintenance work mustbe performed by a qualified electrician andcomply with all applicable national and localcodes.Turn power off and lock out all power beforeperforming service or maintenance work.Do not install in classified hazardousatmospheres without an enclosure rated forthe application.Do not look into fan outlet to determinerotation. Material may unexpectedly bedischarged from the fan. View the fan rotationthrough the back of the motor.To reverse rotation, three-phase power supply: switchany two leads on the output side of the motor starter.Do not interchange a power leadwith the ground wire. Severepersonal injury and/or property damage mayresult.All electrical wiring and connections, including electricalgrounding, should be made in accordance with theNational Electric Code (NFPA No. 70-latest edition).Check local ordinances for additional requirements thatapply.The appropriate wiring schematic and electrical ratingmust be used.
