Standard Construction Features

Wheel

An aluminum, backward-inclined, non-overloading centrifugal wheel is utilized togenerate high-eiciency and minimal sound Wheel cones are careully matched tothe venturi for maximum efficiency. Each wheel is robotically welded and staticallyand dynamically balanced or long lie and quiet operation

DisconnectSwitch

NEMA-1 switch is factory mounted and wiring is provided from the motor as standard(other switches are available). All wiring and electrical components comply with theNational Electrical Code (NEC) and are either UL Listed or Recognized.

Fan ShatPrecisely sized, ground and polished so the first critical speed is at least 25% overthe maximum operating speed. Where the shaft makes contact with bearings, tighttolerances result in longer bearing lie

Bearings100% factory tested and designed specifically for air handling applications with aminimum L10 lie in excess o 100,000 hours (L50 lie o 500,000 hours)

Motor Careully matched to the an load and is mounted out o the airstream

Motor CoverConstructed of aluminum, machine-punched, and attached with fasteners that provideor easy removal and access to motor compartment and drive assembly

Motor CoolingCooling fins located on top of the fan wheel draw outside air through a large spacebetween the fan shroud and the motor cover directly into the motor compartment.Positive motor cooling with fresh air results in maximum motor life.

Liting Points Various lifting points are located on the drive frame and bearing plate (on select sizes).

True VibrationIsolation

Vibration isolators, with no metal-to-metal contact, support the drive assembly andwheel for long life and quiet operation.

Drive AssemblyBelts, pulleys, and keys are oversized 150% of driven horsepower. Machined castpulleys are adjustable or inal system balancing Belts are static-ree and oil-resistant

Lower WindbandHeavy-gauge aluminum with formed edges for added strength and providesweather resistance.

Curb CapCurb cap (with integral deep spun venturi) is constructed of aluminum and is one-piece

for a weather-tight fit.Internal ConduitChase

A large diameter conduit for installing electrical wiring through the curb cap into themotor compartment

With changes in building codes and standards more equipment isbeing required to be seismically certifed in areas o the country not

commonly thought of as being in seismically active zones.The International Building Code (IBC) is designed to provide modelcode regulations that saeguard public health and saety in all UScommunities This code is intended to improve the perormance anddesign o non-structural systems subject to seismic events

The State o Caliornia, one o the most active seismic areas in theUnited States, has the Ofce of Statewide Health Planning and

Development (OSHPD) to regulate the design and construction ohealthcare acilities to ensure they are sae and

capable o providing services to the public atera seismic event. OSHPD developed their own

unique certifcation process to incorporatethe IBC and ASCE testing standards toensure equipment remains operable ater aseismic event

ApplicationsG and GB models

SeismicTesting Criteria

All Greenheck seismically certiied models have been tested using the most severe seismic event thatis ound on the Spectral Response Map per IBC Figures 16135 (1-2) Our testing is perormed underthe worst case scenario using the highest mapped seismic load, highest level occupancy category,worst case site class, and highest code mandated importance factor, thereby allowing Greenhecks

seismically certified fans to be used anywhere in the United States under any conditions

Caliornia OSHPD

Test Protocols

The California Office of Statewide Health Planning and Development (OSHPD) requires all certifiedmodels be shake table tested in accordance with ICC ES AC-156, in which the fans are physically

subjected to the same or greater forces than they will see during a seismic event. SubjectingGreenheck model G and GB fans to this type of testing ensures the fans will operate withoutproblems ater a seismic event

OSHPD Certiication

No 0148-10The OSHPD certification numbers and supporting documents can be viewed on OSHPDs

website ensuring that the fan has been subjected to and passed rigorous testing standards.

State LicensedPE Calculations

When using the fans in applications which are not covered by California OSHPD standards,

Greenheck models G and GB have been certiied by a third party engineering irm to IBC 2006, 2009and ASCE 7-05 standards These engineers hold proessional engineering (PE) licenses in all 50states, so no matter where your job is located, you are backed by a P.E. signature for your state.

CertiiedIndependentThird-Party Testing

All Greenheck seismically certiied an models have gone through extensive testing proceduresGreenheck models G and GB have been certiied to IBC 2006, 2009, ASCE 7-05 and CaliorniaOSHPD standards through both engineering calculations and shake table testing o all models byindependent third party engineering irms

High Wind and Hurricane - G and GBGreenheck is leading the High Wind Standard or roo top ans andventilators. Forceful winds and wind-borne debris are the cause of

most hurricane damage. Hurricane winds start at 75 mph. At speeds

over 150 mph, wind can exert a force of 75 pounds per square foot

of pressure or over 900 pounds on a fan and curb. Forceful winds arenot the only problem, wind-borne debris can also cause detrimental

effects to objects and structures. High winds and extreme forces

are the cause of most storm damage. By analyzing calculations,

computer simulations, actual testing, and other standardsGreenheck developed the High Wind Standard

StructuralPerormance Load

A static load that is 15 times the design load (915 pounds per square oot o pressure) is appliedboth positively and negatively to simulate wind force loads in each direction. Structural Performanceper Dade County Protocol TAS-202 (ASTM-E330)

Miami-Dade CountyTest Protocols

Greenheck worked with Miami-Dade County to outline a High Velocity Hurricane Zone standard forrooftop fans. Greenheck model USGF was the first rooftop fan certified and approved by the Miami-

Dade Building Code Compliance oice and Texas Department o Insurance or use in hurricanezones. Models G and GB have been certified by an independent third party to the ASTM E-330 Static

Pressure Dierence Standard, Florida Building Code Test Protocol TAS-201 (large missile impact),202 (static pressure dierence) and 203 (cyclic pressure) Static Pressure Dierence

Miami-Dade NOANumbers

The certifications can be viewed on the Miami-Dade County website under the NOA numbers listedbelow. Models G and GB are the first downblast aluminum fans in the industry that have received

a Miami-Dade NOA for high wind (150 mph) and hurricane zones. Miami-Dade NOA 09-0624.09 for

models G and GB

Florida ProductApproval

Florida Product Approval ensures that products which have been approved can be used anywhere in

the State of Florida which are not governed by the Miami-Dade County high wind regulations. More

information can be found on the Florida Building Code website. Florida Product Approval FL13225.1

or models G and GB

State LicensedPE Calculations

Structural calculations perormed by a licensed Proessional Engineer (PE) on models G and GBinclude Finite Element Analysis (FEA) and a stamped PE report o the ans compliance to ASCE7-02 Minimum Design Loads or Buildings and Other Structures Standard and the Florida BuildingCode The ASCE 7-02 Standard meets the IBC, Florida and Miami-Dade codes The models havebeen proven to withstand winds in excess of 150 mph (75 psf).

Computational FluidDynamics (CFD)

All Greenheck high wind models have been analyzed using Computational Fluid Dynamics (CFD).CFD is computer software designed to simulate the flow of high speed (150 mph) winds over the

surface of objects. The software records the force profile exerted on the fan so it can be utilized

in Finite Element Analysis (FEA)

Finite ElementAnalysis (FEA)

Utilizing the results from CFD analysis, Greenheck can accurately predict the stress, strain,

and deflection resulting from high wind loads. Greenheck high wind units have been proven

to withstand 150 mph winds through Finite Element Analysis utilizing CFD results.

Operates on AC power thats converted to DC

providing a more efcient motor operation ascompared to an AC operation

The motor can attain up to 85% efciency and

reduce energy consumption

Watt savings of 30-70% depending on RPM.

Note:As motor speed is turned down, efciencystays constant as compared to an AC motor that

decreases dramatically.

Operates cooler than a standard AC motorA cooler motor has longer motor lie and reducesenergy consumption
