Construction OptionsVibration AnalysisAll centrifugal wheels undergo a computerized balance analysis to a grade of G6.3. In addition, USF 500 seriescentrifugal products endure a complete mechanical vibration test after assembly. Our custom data acquisitionsystem uses tri-axial accelerometers to measure the vibration in three planes at the design operating speed. Apermanent record for each fan’s performance is kept on file and is available upon request.The standard “filter-in” vibration levels attainedmeet the requirements of Fan Application BV-3as defined in AMCA Standard 204-05 “BalanceQuality and Vibration Levels for Fans”. Consultfactory if more stringent vibration levelsare necessary.Drive TypeFilter-InVibration Limit(Rigidly Mounted)Belt0.15 in/sec-pkDirect Arrg. 40.08 in/sec-pkDirect Arrg. 80.15 in/sec-pkCopies of these signatures are kepton file and are available upon request.500 series onlySplit HousingsQuad split housings can solve many space limitation problemsin both retrofit and new construction situations.Not available on 45 discharges TAD, BAD.Size Limitations:7 - 73Bolt-on Pedestal Standard33 - 73 Quad Split Optional500 series onlyShown with bolt on pedestalandpedequad split housing (option)Premium BearingsBelt drive centrifugal products are manufactured with “Air Handling Quality”self-aligning ball or roller pillow block bearings. All bearings include zerk fittingsfor relubrication and are selected for a basic rating fatigue life of L10 in excess of80,000 hours (L50 at 400,000 hrs.) at the maximum RPM for the selected pressureclass. 400 and 500 series models utilize concentric locking collars for smootheroperation and providing superior grip force between the bearing collar and fan shaft.For more critical applications, 500 series models offer bearings with a minimumL10 life in excess of 200,000 hours (L50 at 1,000,000 hrs.)L10 LifeEqual to L50 orAverage LifeIndustry Standard40,000 hrs.200,000 hrs.USF Standard80,000 hrs.400,000 hrs.500 Series Upgrade200,000 hrs.1,000,000 hrs.L10 life implies 90% reliability or 10% failure rate after the stated hours.L50 life implies 50% reliability or 50% failure rate after the stated hours.7

Fan classes are designated as 0, I, II, IIIor IV. As the fan class increases, the outlet velocityand pressure requirements increase as definedin AMCA Standard 99. As the outlet velocity andpressures increase, the fan construction (materialgauge, shaft diameter, motor size, etc.) must alsochange to physically accommodate the fasterRPMs required.150090% WOV13711200105190060010203040506070Volume (cfm x 1000)0204060801003Volume (m /hr x 1000)Class0ClassIClassIIClassIIIClassIV9

AccessoriesVibration Isolators and Isolation BasesGreenheck offers a complete package of vibration isolators, isolation bases and inertia bases to simplify fieldassembly and reduce transmitted vibrations.Refer to the catalog on www.greenheck.com/Resources/Library/Literature. Search for Mounting Bases andVibration Isolation.Mounting TypesDirect MountNo base required, isolators are attached directly to equipment. Directisolation can be used if equipment is unitary and rigid without the use ofadditional support. Direct isolation is not recommended for equipmenthaving large overhung loads (e.g. motors on arrangement 9 fans). If thereis any doubt that equipment can be supported directly on isolators, usebases or consult the factory.Isolation BaseIsolation bases consist of formed steel members welded into a rigid onepiece base. A motor slide base is included where applicable. Bases arerequired for all arrangement 1 and 3 fans with independently mountedmotors. Isolation bases are available without isolators, with rubbermounts or with spring mounts. All formed steel bases with spring mountsincorporate height saving brackets.Isolation basewith heightsaving bracketsInertia BaseInertia bases may be desirable where isolation bases do not providesufficient mass or where discharge velocities cause greater reactionforces. The additional weight of the concrete reduces the vibrationamplitude and reduces reaction forces from fan thrust and start andstop motion. Concrete is by others.Note: Motor slide base is included on arrangement 1 & 3 fans.Inertia baseIsolator TypesRubber MountNeoprene mountings consist of a steeltop plate and base plate completelyembedded in colored (oil-resistant)Neopreneneoprene for easy identification ofcapacity. Neoprene mountings are furnished with atapped hole in the center. This enables the equipmentto be bolted securely to the rubber mount.Free-Standing Open Spring MountFree-standing spring isolators areunhoused laterally stable steel springs.They provide a minimum horizontalstiffness of 0.8 times the rated verticalstiffness and provide an additional 50%FreeStandingoverload capacity. These isolators areequipped with a top mounted adjusting bolt and anacoustical non-skid base. Springs are color coded oridentified to indicate load capacity.10Restrained Spring MountRestrained spring isolators consist oflaterally stable, free-standing springsassembled into a steel housing. Theseassemblies are designed for verticaland horizontal motion restraint.Springs provide 50% overload capacityRestrainedand are color coded or identified toindicate load capacity. Restrained spring mounts arerecommended for equipment subject to wind-loadingor large torquing forces. They are also used forequipment subject to large weight changes such asswing-out fans.

Inlet and outlet guards meetOSHA guidelines.Backdraft DamperBackdraft dampers are available in galvanized,painted steel or aluminum construction and includecounterweights for tight closure when the fan isde-energized.Belt GuardBelt guards are designed to allow easy access to thebelts and pulleys for service. All belt guards includetachometer openings to monitor the fan speed aswell as an access panel for testing belt tension. Beltguards meet OSHA guidelines.Motor Cover (Arrg. 1 W or Z, 3, 4, 8, 9)A weatherproof motor cover shields the motorcomponents from dust, dirt and moisture foroutdoor installations.Shaft Guard (Arrg. 1, 8 or 9)Shaft guards are designed to cover shafts andbearings. Extended lube lines are optional for bearinglubrication without removal of the guard. Shaft guardsmeet OSHA guidelines.Disconnect SwitchShaft SealGreenheck offers a wide selection of NEMA ratedfusible or non-fusible disconnect switches. Switchescan be factory mounted or shipped loose forfield installation.A felt, neoprene, or ceramic shaft seal with a rub ringis available for operation at high temperatures or forexhausting contaminated air.Drain with PlugA one-inch (25 mm) threaded drain connection islocated at the bottom of the fan housing to drainwater that may accumulate.Extended Life BearingsExtended life bearings are selected for a basic ratingfatigue life L10 per ABMA Standards in excess of200,000 hours at the maximum RPM. L10 is the lifeassociated with 90% reliability of a bearing.Extended Lubrication LinesSingle-width fans are available with flexible nylonor copper tubing extending from the bearings toconveniently located grease fittings mounted on thefan pedestal (or on the exterior of weatherhood if aweatherhood is supplied).Stainless Steel ShaftStainless steel fan shafts are available for applicationswhere standard carbon steel shafts may exhibitexcessive corrosion or heat stress.Sure-Aire Non-invasive flow monitoring system capable ofcapturing accuracy within 3% and available with orwithout electronics. Clean air applications only.Weatherhood (Arrg. 1 X/Y, 10)Vented steel weatherhoods protect the motor anddrive components from rain, moisture, dust, and dirt.Weatherhoods meet OSHA guidelines and are easilyremoved for service access.Volume Control:Grease ContainmentVolume Control DamperGrease trap is designed to collect grease residue toavoid drainage onto roof surface. Grease traps shiploose for field installation.Control dampers are available in paintedsteel, aluminum or stainless steel.Actuator options include manual quadrantor electric.Heat SlingerThe heat slinger is an aluminum cooling disc mountedon the fan shaft between the inboard bearing and theblower housing to dissipate heat conducted along thefan shaft.Inlet Companion FlangeVFD Rated MotorVariable frequency drives (VFD’s) change thefrequency of the input power to the motor, whichresults in changing the motor’s speed. Changing thespeed of the fan provides the greatest potential forenergy savings at partial loads.Punched companion inlet flanges are available onsingle-width fans.Inlet and Outlet FlangesOptional inlet flanges on single-width fans are prepunched and welded to the inlet collar. Punchedoutlet flanges are standard on fan sizes 33-73.11
