HF Thermoplastic Centrifugal Fans1
HF-centrifugal fans are ideally suitable for extraction ofexhaust air and gases. These fans are used mainly forextraction of corrosive fumes in such applications as:
• Electroplating and Metal Finishing• Circuit Board Manufacturing• Chemical Processing• Pulp and Paper• Water and Waste Water Treatment• Industrial, Government & Educational Laboratories• Hospitals• Pharmaceutical
They are available with direct drive (design shape D) orbelt drive (design shape R).
HF-centrifugal fans are produced in sizes from 3 to 20inches or 75 to 500 mm.
Depending on thee impeller sizes (15 or 17) flow ratescan range from 20 to 7000 CFM or 34 to 11,800 m3/hat a maximum static pressure of 6.5 inches of W.G or1600 PA.
A fan efficiency of 81% is attainable at the optimumoperating point. Greater air performance is achievablewith the HF R... 13 D/R series fan ranging in sizes 20 to40 inched (500 to 1000 mm) in three pressure stages.Performance rates range from 1800 to 88,000 CFM(3000 to 150,000 m3/h at a maximum total static pressureof 12 inches [3000PA]). The pressure stage isdifferentiated through the circumferential of the impeller.
HousingThe HF series of fan housings in generally made fromrotationally moulded flame and UV retardant polyethylene(PEs). Other thermoplastic materials are available uponrequest.
The housing is fitted with a splinter guard around thecircumference. A condensate drain is installed at thelowest point of the housing.
HF fans are normally produced in an upblast position andcapable of rotating the exhaust outlet in steps of 45º. Thenormal position is either refered to as GR 360 or GL 360.The exhaust outlet may be connected via a flexibleconnector of flange outlet. Since the outlet is round;attachment to round ducting does not require a transitionfitting.
ImpellerThe impeller is made of flame retardant polypropylene(PPs) that is balanced both statically and dynamically. Inthe case of a direct drive fan the impeller is secured tothe motor shaft by means of a taper lock bushing. Onbelt drive fans the impeller is secured in the same way(taper lock bushing) to the drive shaft and supported byflanged double bearings.
The impeller can be removed without having to dismantlethe housing from the frame.
The fan is mounted to a welded steel frame that is hotdip galvanized.
Accessories:• Flexible vibration connectors• Inlet & outlet flanges• Neoprene or spring vibration isolators• Shaft seal• Inspection port• Weather cover• Starter & disconnect switches• Variable frequency drive

HF-fans are suitable for exhausting agressive corrosivefumes or humid air. Explosive atmosphere can bedelivered with HF-fans especially designed for thispurpose. The permissible gas temperatures for plasticsmost frequently used in our fans are generally:
• For PVC: 0 °C up to 50 °C• For PE, PE-FR (PEs) -20 °C up to 60 °C• For PP, PP-FR (PPs): 0 °C up to 70 °C • And for PVDF, GRP, and CRP: -10 °C up to 100 °C
These temperature ranges must be reviewed and ifnecessary limited depending upon gas composition andimpeller’s rotational speed. In case of exceptionallyaggressive media, the reduction must be reviewed anddetermined from case to case.Our data sheets containinformation about mechanical limits. Other applications ordesign changes must be implemented in consultationwith the manufacturer.
Rough assessment of chemical resistance can be madeaccording to the following instructions:
Chemical resistance of materials used can be derivedfrom the material manufacturers. In case of critical gasmedia, please inquire in writing giving all the conditions ofthe application.

In case of centrifugal fans, the medium is entering theimpeller axially through ducting, a suction box or directlyfrom outside. The impeller is equipped with six bladesbeing bent backward, thus deviating the medium to radialdirection. The conversion from flow energy into staticpressure is effected to a great extent in the impeller.
The standard execution of this high-efficiency impeller ismade of PPs, and the transmission of the torque iseffected by means of a steel hub being mounted in theimpeller and being protected against corrosion. Eachimpeller is balanced electro-dynamically in two levels,balancing quality Q 6.3, according to VDI 2060.
The plastic housing is provided to bring the mediumtogether and to drain it. It is dimensioned according tothe required nominal pressure rates. The standardhousing is equipped with a condensate drain beinglocated at the lowest point, which can be connected toa discharge pipe in case of excessive formation ofcondensate. The suction nozzle is fastened by screws,and thus can be easily removed. A gasket is inserted inthe nozzle and at the back panel of the housing. Thehousing is fastened to the base frame.
The base frame (rack) is made of hot dip galvanized steel.Predrilled holes are prepared to fasten the vibration
absorbers. The vibration absorbing elements reduce thetransmission of the dynamic load to the substructure.
The standard fans can be delivered in two executions.
Design D Direct Drive. The impeller is fastened directlyat the motor shaft. The standard motor is ahigh efficiency TEFC.
Design R Belt Drive. The drive is affected by V-belts.The impeller is fastened on a steel shaft of aflange-type double bearing. The standardmotor is a high efficiency TEFC. A shaft/beltguard consists of PVC or PP material.
The plasticized PVC flexible connectors are available toprevent the transmission of vibrations from the fan to theducting. They are fastened at the fan by means of a bandclamp fitting of stainless steel.
The weather-protection hood of plastic material or steelabove the drive is recommended in case of an outdoorinstallation of the fan.
An inspection/access port is available for observation andeasy cleaning of the impeller.

All shipments are F.O.B. shipping point except whereotherwise stated. The term F.O.B. shipping point meansthe carrier accepts all responsibility upon accepting theshipment at Fabco’s facility. Thus any claims must besettled between the buyer and the carrier.
All centrifugal fans are shipped crated to minimizedamage during shipment.
Upon receipt of shipment, all goods are to be checkedfor damages and for missing parts using the shippingdocuments. Please inform the manufacturer immediatelyin case of any discrepancies or concerns.
The fan should never be lifted by the shaft, housing,motor, belt guard or accessories.
Prior to installation the fan is to be checked that all looseparts are secured and if the impeller can be turned easily.
Critical to every fan installation is a strong, levelfoundation. Reinforced poured concrete provides anexcellent foundation and is used in most installations.Steel beams are also acceptable, but must be sturdyenough, with welded construction, to prevent flexing andvibration.
To eliminate vibration and noise from being transferred tothe building, vibration isolators should be used. The typesof vibration isolators currently available are: elastomer,shearmount, compression mount, ribbed neoprene andcork, natural cork and metal springs. Consult theappropriate isolator catalog for specific applications.
The isolators are installed between the isolation base andthe concrete or steel foundation. The fan is mounteddirectly on the isolation base and must be supported theentire length of the fan base angle.
After the fan, isolator base and isolators are installed, theentire assembly must be leveled. Position the level on theisolation base, not the fan shaft, for proper leveling.Additionally, the motor and fan shafts must be level andparallel relative to each other for proper alignment.
The fans are to be connected to the ducting on thesuction and the pressure side using the elastic collars.The plastic drain plug at the condensate drain is to beremoved.
According to the IEC standard 34-1, the standard motorsbeing supplied are designed for normal operatingconditions. The ambient temperature should not exceed+40 °C, the installation height should be below 1000 m,and the atmospheric pressure should not exceed 1050hPa. If the motor has been designed for deviatingspecifications, it is stated on the nameplate of the motorand/or in our order confirmation. The cooling air supplyshould not be hindered.

Prior to starting the unit, the capacity rates of the motorare to be compared with the available power supply andmains frequency. The power supply cable should beprotected from damage and should be dimensionedaccording to the power consumption.
The access to the electric motor is only allowed when thepower supply had been cut-off, locked out and under dryambient conditions.
Connection and location of the clamping saddles is to beeffected according to the wiring diagram being located inthe terminal box. Each motor should always be protectedby a motor disconnect switch.
The protective motor switches are not included in ourstandard delivery scope.
The electric connection must be performed by qualifiedpersonnel. Prior to the trial run, all rotating parts are to beprotected according to the regulations for prevention ofaccidents to avoid unintentional contact. The motor is tobe switched-on for a short time, and the rotation of thefan is to be checked. The rotation should correspond tothe direction sign attached at the housing.
On each new connection, the rotation is to be checked.During the starting phase, the current consumption ratemay be six to eight times higher than the nominal currentbeing indicated on the motor nameplate. At nominal
speed, that rate should not exceed the nominal currentrate. The motors are always designed for the operatingspeed being indicated on the nameplate. The maximumload of the motors is the current value multiplied by 1.5for two minutes.
Radial fans with a motor capacity greater than or equal to4 kW should be started with a star connected threephase system, and the operation should be continuedwith a delta connection. Should the connection time ofthe star connected three phase system be not sufficientto start the fan, the starting phase can be extended byinstallation of a time lag relay. A better solution would beto start by means of a suitable frequency converter.
Depending on design and operating stress, measuresshould be taken to avoid a deposit of solid matter on theimpeller and the housing. Ensure that the impeller isnever out-of-balance, otherwise it will sustain damage.The fan is to be protected in a suitable way to avoidingestion of foreign matter. Installation of protectiondevices is to be accomplished in such a way that easyaccess for performance and condition checks is ensured.According to the UVV regulations, the fans should beequipped with a splinter guard (plasticized PVC collar orgrid around the housing).
Check all screwed connections and retighten them, ifrequired.
4. Start-up
HF Thermoplastic Centrifugal Fans8
The maintenance intervals are dependent on the natureand composition of the medium to be exhausted and thefan used (direct drive or belt drive). While themaintenance interval for fume cupboards may be severalyears, exhausting of a pickling bath requires amaintenance interval of only one week. The maintenanceinterval required is to be determined via several checksduring the initial phase.
Prior to any cleaning or maintenance tasks, the fan is tobe switched-off and to be protected from unauthorizedstart-up. Make sure, that the impeller comes to acomplete stop. The regulations for prevention ofaccidents are to be observed. Only qualified personnelshould perform maintenance tasks.
Check the fan periodically for smooth running. Should itbe running rough, it may require cleaning andrebalancing. Cleaning of the fan should be effected byrinsing or by careful mechanical removal of the impurities.Should there be any damage to the impeller, themanufacturer is to be consulted immediately.
Maintenance of the motor is to be performed accordingto the instructions of the motor manufacturer.
The flange-type double bearings are maintenance-free.The grease filling of the sealed deep groove ball bearingsis sufficient for lifetime and corresponds to a calculatedlifetime of approx. 20000 to 30000 operating hours. Themaximum admissible storage temperature should be90 °C during standstill, and 70 °C during operation.
The main reason for abnormal heating of the bearings,excessive vibration and fan noise is insufficient V-belttensioning. Consequently, belt tension is to be checkedparticularly during the first weeks and should beadjusted, if required.
This is particularly important, if the fan has not been usedfor an extended period or if the start-up of the fan is at alater date. Insufficient tension will result in slipping andincreased wear. Over tensioning of the V-belts results indamaged bearings.
Prior to checking the V-belt tension or prior to areplacement of the V-belts, the fan is to be protectedfrom unintentional adjustment.
When replacing V-belts, ensure that the shafts andpulleys are in true alignment. The groove profile shouldbe exact and the grooves should be clean.
The axis distance is to be reduced sufficiently prior toinsertion. In case of series HF R, this is done byadjustment of the retaining plate of the motor. The V-beltsare to be inserted separately by hand into the grooves.Never insert the V-belts over the pulley, since this willresult in damage of the belts. The V-belts are to betensioned and, if required, to be checked andretensioned after 1 to 4 operating hours.
