OUTLET FLANGESThe flanges are standard on all

HPCA series centrifugal fans. Theheavy duty, undrilled flange has a

smooth sealing face. Drilling isavailable as an option.

SHAFT SEAL—\A neoprene shaft seal is \used to prevent leakage of \corrosive fumes which coulddamage the bearings andthe shaft. The elastomer

:::etthe fiberglass

SHAFTSAll HPCA series fans utilize atumed ground and polishedcarbon steel shaft material.Stainless steel is availablefor special orders onrequest.

BEARINGSGrease lubricatedfully self-aligned pillow blockball bearings are standardequipment.Minimum startingfriction,simple maintenanceand long, trouble-free lifeexpectancy, make themideal for fan service.

,—HOUSING DESIGN

The spiral shaped housing is

designed to collect the air leaving

the periphery of the wheel and

reduce its velocity with a minimum

of turbulence, thereby efficiently

converting velocity pressure to

static pressure for increasedperformance.

,,— STREAMLINED INLET CONE

A new and improved inlet cone

hasbeen provided allowing the

correct overlap into the wheel.This design allows the correctair entry into the wheel and prevents leakage.

FIBERGLASS CENTRIFUGALAIRFOIL WHEELThe backward-inclinedairfoil wheel has ten airfoilprofile blades with a vinyl esterresin exterior and a high densitylight weight interior allowingClass Ill speeds. The imbeddinghub is bolted and bonded to thebackplate and permanentlyencased with a FRP cover.

CUTOFF PLATEAn extended and redesignedcutoff plate has beendesigned for this new airfoil wheelto provide maximum efficiency.

DRAINEvery Harrington centrifugal exhaustfan is supplied with a 1” threaded drainoutlet located in the bottom most positionof the housing.

AIR POLLUTION CONTROL GT)


FEATURES AND GENERAL INFORMATION

Air Movement and Control Association Seal

Harrington EnvironmentalEngineering certifies that theHPCA series FRP centrifugalAirfoil fans shown herein arelicensed to bear the AMCA Seal.The ratings shown are based ontests and procedures performedin accordance with AMCAPublication 211 and comply withthe requirements of the AMCACertified Ratings Program.

The Harrington backward inclined Airfoil wheel is the result of yearsof design and experimentation. This unique Airfoil blade profile is acomposite structure consisting of a premium grade vinyl resin fiberglass exterior and high density light weight interior. This modemconstruction provides excellent chemical resistance to a wide variety of corrosive chemicals and is practically impervious to mostchemicals. The light weight construction and unique Airfoil profileshape allows operation at higher speeds up to Class Ill constructionwithout distortion or bond separation and allows pressures up to 18inches WG.

The ultimate measure of fan performance is operating efficiency.High efficiency means lower operating cost throughout the life of theequipment. The HPCA Airfoil design provides static efficiencies upto 83%. This feature will provide a tremendous energy savings.

Fourteen sizes are available from models HPCA 2000 to 7300.Harrington recommends using the flat blade backward inclinedmodel HPC series, on fans below the HPCA 2000 model, since themerits of airfoil are lost in smaller fan sizes.

All Harrington HPCA series Centrifugal Airfoil fans conform to ASTMD41 67 standard specifications for fiber reinforced plastic fans andblowers. For applications requiring an additional corrosion barrier,Harrington recommends an interior veil on the fan scroll providing aresin-rich layer.

All wheels are statically and dynamically balanced on electronicallycontrolled balancing machines. The necessary weight adjustmentsare made by removing excess material, or by permanently bondingfiberglass material to the wheel. After completed fan assembly, thefans are test run at the customers operating speed to locate andcorrect any minor misalignment that may have occurred duringassembly. They are checked for proper bearing operation.

Sound information is available from Harrington. This data is theresult of laboratory testing based on AMCA standard 300 and processed by the procedures shown in AMCA Bulletin 301. The AMCACertified ratings seal applies to air performance only.

FAN SELECTION AND PERFORMANCE

The Performance Tables shown in this brochure are based on unobstructed air flows into the inlet of the fan. During installation, the faninlet conditions should be designed to allow the air to enter thehousing resembling a fan with an unobstructed inlet. The fan performance can be adversely effected by poor inlet conditions creating uncontrolled spin, unequal air loading or imbalance. Elbowslocated directly at the inlet should be avoided and properly sizedinlet boxes or straightening vanes should be utilized. It is good practice to include the equivalent of two duct diameters prior to the faninlet.

The addition of a short outlet stack will improve the overall performance of the fan. Testing has shown up to a 7% improvement inperformance by the addition of an outlet stack.

The BI Airfoil wheel blades provides non-overloading performance.This allows the brake horsepower to level off at a point wheremotors can be economically selected so they will not overload if thesystem pressure drops.

The brake horsepower shown in the performance tables does notinclude the drive or belt losses. Normally, the belt drive losses varyfrom 5% to 20% of the motor horsepower output.

The estimated belt loss can be obtained using the table located onpage 4.

The chemical and structural properties of fiberglass are excellent.FRP fans moving air at higher temperatures will usually effect thechemical resistance. In addition, the maximum safe speeds shouldbe de-rated using the following table:

MAXIMUM SAFE SPEED CORRECTION FACTORSTemperature (°F) 70 100 150 175 200Factor 1.0 1.0 .95 .93 .91

To obtain the new maximum safe speed when temperature isinvolved, multiply the maximum safe speed as listed for each fansize by the correction factor.

Each of the following capacity tables include a CFM, static pressure,outlet velocity and the corresponding RPM and BHR If capacitiesare not at standard conditions (70 degrees F at sea level) or at standard density of .075 pounds/Cu.Ft., correction factors must beapplied to static pressure and BHR The most efficient fan operationabove the solid black line represents peak efficiency and the mostquiet performance.

Fan performance is shown for Class I, II and III. The maximum safetip speed for each construction is 10,000, 14,000 and 17,000 feetper minute. The capacity table also includes the maximum fan PRMfor each Class construction

FLEXIBLE CONNECTIONS are supplied with stainlesssteel draw bands and are fabricated from a material suitablefor service with corrosives contained in the air stream.

GRAPHITE IMPREGNATION is used for applications whichhandle potentially explosive fumes or gases. The interior airstream surface is coated with a graphite rich resin coat andgrounding strap secured to the steel base. During installation, the steel fan frame should be grounded.

GRAVITY DAMPERS constructed of fiberglass prevent rainfrom entering the inlet duct work and foreign objects fromentering the fan wheel during shut down periods.

INLET BOXES are fabricated of FRP and provide a convenient means of locating an inlet 90 degrees to the fan inletwith predictable entry losses.

INLET OR OUTLET SCREENS can be installed to offer protection on the inlet side from the rotating fan wheel or on theoutlet to prevent foreign objects from entering the wheelhousing.

INLET VANE AND OUTLET DAMPERS fabricated of FRPor 316 stainless steel provide a means of volume controlwith corrosion resistance. Dampers can be motorized.

INTERIOR VEIL is standard on the fan wheel blades and theback plate. If an additional barrier is required because ofsevere chemical service application on the fan housing interior, a veil interior can be provided on the fan housing as anoption. However, the fan housing already includes a resinrich and smooth coat without the use of a surface veil.

MOTORS are available in many different enclosure types(TEFC, ODP, High Efficiency, TEEP, etc.) and voltages. Twospeed motors can be supplied or Harrington can mount acustomer supplied motors. TEFC Inverter Duty motors arealso available.
