INTRODUCTION

Woods Air Movement Limited has made Axial flow fans for specialist applications and arduousenvironments for over 80 years.

As an acknowledged leader within the industry we have developed a series of bifurcated casedaxials, utilising the improved performance JM Aerofoil range and taking into account the two mostimportant factors to be considered - safety and economy.

All fans are of the highest quality, built to the latest British and International standards, and incor-porating motors rated in accordance with BS5000 Part 99 and IEC 34-1.

This catalogue details the range of pre-designed products available with a Bifurcated casing.Other product variants are available on an individual order basis, please enquire of your localsales office if extra information is required. (For details visit www.woods-fans.com).

The JM AEROFOIL Bifurcated Range

JMThis catalogue contains the complete range of JMAerofoil Bifurcated fans, either for +80°C or+200°C continuous operation, from 400 mm to800mm diameter. The impeller pitch angles arefactory set to individual performance requirements.

JM Series 33This is our range of small bifurcated fans and con-sists of 150mm, 250mm and 300mm diameters fortemperatures of 200°C. For our range of continuous operation high tem-perature smoke clearance bifurcated fans pleasesee Fans in Fire Safety catalogue ref: C10 or con-tact your nearest sales office.

OTHER BIFURCATED RANGES

Large Bifurcated RangeFor higher duties there is our large J bifurcated fan48" (1250mm) diameter. For full details pleaseenquire at your nearest sales office.

APPLICATION

4

THE JM BIFURCATED FANThe JM Aerofoil Bifurcated fan has been developed to handle; wet or dirty atmospheres, hot gases,emergency smoke clearance, dust laden air.The motor is isolated from the main air stream by a tunnel which extends to the side of the mainfan casing only. The motor is cooled by air directly over its carcass by means of a cooling fanmounted on a shaft extension at the tail end. An air splitter in the tunnel separates the incomingcool air from the outgoing warm air. On sizes 400 mm to 1000 mm the mouth of the tunnel is spig-otted so that an extension duct giving access to normal atmosphere can be fitted in cases wherethe fan is mounted inside equipment, such as a drier, where air is required from another area lowerthan ambient for motor cooling.

TYPICAL APPLICATIONS Temperature RangeDifferent sizes of fan are rated for different maxi-mum temperature as in the table below:-

Maximum Temperature

80°C 200°C 320°C*150 - 300 mm X X

400 - 1000 mm X X

*Special - made to order only

Mists and CondensationThe Bifurcated fan is capable of handling mists upto 100 % relative humidity. When there is a dangerof vapour condensing out in the fan duct 150 mmto 500mm diameter fans should not be mountedhorizontally due to their case design. All ductsshould be laid to a slight fall to facilitate drainage.DustsWhere there is a danger of dusts building uparound the motor of a standard axial fan the

Bifurcated fan eliminates this problem with itsmotor out of the airstream. Care must betaken to maintain minimum velocities for theconveying of dusts in the air stream. (If thedust causes a change from standard air den-sity (1.2 kg/m3) please refer to your nearestsales office).Flammable GasesWith the additional fitting of a spark minimisingimpeller track, the fans are suitable for Group2A and 2B gases. The fan must be mountedoutside of the hazardous area. The shaft sealmust be correctly maintained.Corrosive ChemicalsThe Bifurcated fan is suitable for some mildchemicals that will not corrode the galvanisedcasing or the seal of the motor shaft throughthe case. Additional protection can be provid-ed by an epoxy paint finish. Please refer corrosive chemicals such asacids and solvents to ourselves where we canadvise on the suitability of the fan.

SPECIFICATION

5

MotorsConstructed from aluminium as standard withspecial stud and pad mounting fixings. Suitablefor horizontal through to vertical shaft operation.Supplied IP55Insulation is Class F, with Class F temperaturerise.Bearing lubricated with wide temperature rangegrease, relubricatable or sealed for life bearingsdependant on size.The motor is cooled by ambient air drawn intothe tunnel which extends to the side of the cas-ing, and is suitable for continuous operation forup to 40°C ambient.

Speed ControlWoods do not offer speed control for the bifur-cated fan by conventional electronic or auto-transformer speed control. This is due to themotor construction. For inverter drive applica-tions enquire at Colchester.

StartingStandard three phase motors of 5.5 kW outputsand above are usually provided with Star/Deltastarting connections.

Electrical Supply230 V +10/-6 %; 50Hz; single phase (1φ )*400 V +10/-6 %; 50Hz; three phase (3φ )(60Hz and other voltages are available onrequest).

CasingsThe JM Aerofoil Bifurcated design is generallysimilar to a normal axial flow fan, but the motoris isolated from the main air stream by a tunnelwhich extends to the side of the fan casing.The casing of the 150mm to 500mm diametersizes have an enlarged bore located around themotor to permit adequate cross sectional areafor air to flow round the motor tunnel. The 630mm to 1000 mm diameter sizes have casings ofconstant diameter. ImpellersSmall Bifurcated 150 mm - 300 mm Cast aluminium silicon one piece with fixedaerofoil section blade.Large Bifurcated 400 mm - 1000 mmHigh pressure die and clamp plate, with equallyspaced, fully adjustable, high pressure die castsection blades.

The direction of airflow through the fan and the mounting position are defined as the “Form ofRunning”.Woods only offer Form B running bifurcated fans as Form A fans have a marked loss in perform-ance. For vertical operation add suffix “U” for airflow up, or suffix “D” for airflow down.Arrows indicating correct rotation and the direction of air flow are incorporated on the fan ductnameplate.

TestingThe air and sound performance data has beenmeasured by the latest version of British andInternational Standards:-ISO 5801 category D (fully ducted) method fortesting air performance (supercedes BS848 Pt11980).BS848 Pt 2 1985, method of noise testing.It is essential, when comparing fan performances,that the same installation category and teststandards are used at all times.

Acoustic DataThe sound levels quoted are based on testscarried out under the Woods certified laboratoryconditions. Using the spectrum correctionsstated on each performance chart, an unweight-ed sound power spectrum can be obtained forthe fan.

Motor RatingsThe motor ratings, starting, full load currentsand speeds refer to the maximum output ofthe motor. When the impeller does not requirethe full output, the power and current will beless than the maximum quoted.
