JM AEROFOIL - BIFURCATED INTRODUCTION Woods Air Movement Limited has made Axial flow fans for specialist applications and arduous environments for over years. As an acknowledged leader within the industry we have developed a series of bifurcated cased axials, utilising the improved performance JM Aerofoil range and taking into account the two most important factors to be considered - safety and economy. All fans are of the highest quality, built to the latest British and International standards, and incorporating motors rated in accordance with BS5 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 local sales office if extra information is required. (For details visit www.woods-fans.com). The JM AEROFOIL Bifurcated Range JM This catalogue contains the complete range of JM Aerofoil Bifurcated fans, either for +C or +2 C continuous operation, from 4 mm to mm diameter. The impeller pitch angles are factory set to individual performance requirements. JM Series 33 This is our range of small bifurcated fans and consists of 15mm, 25mm and 3mm diameters for temperatures of 2 C. For our range of continuous operation high temperature smoke clearance bifurcated fans please see Fans in Fire Safety catalogue ref: C1 or contact your nearest sales office.

JM AEROFOIL - BIFURCATED APPLICATION THE JM BIFURCATED FAN The 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 main fan casing only. The motor is cooled by air directly over its carcass by means of a cooling fan mounted on a shaft extension at the tail end. An air splitter in the tunnel separates the incoming cool air from the outgoing warm air. On sizes 4 mm to 1 mm the mouth of the tunnel is spigotted so that an extension duct giving access to normal atmosphere can be fitted in cases where the fan is mounted inside equipment, such as a drier, where air is required from another area lower than ambient for motor cooling. MOTOR COOLING AIR OUTLET TERMINAL BOX MOTOR COOLING INLET MOTOR PROTECTION TUNNEL AIRFLOW FORM B ONLY JM IMPELLER 4/5 fl BIFURCATED DUCT COOLING FAN TYPICAL APPLICATIONS Temperature Range Different sizes of fan are rated for different maximum temperature as in the table below:- Maximum Temperature C 2 C C* 15-3 mm X X 4-1 mm X X *Special - made to order only Mists and Condensation The Bifurcated fan is capable of handling mists up to 1 % relative humidity. When there is a danger of vapour condensing out in the fan duct 15 mm to 5mm diameter fans should not be mounted horizontally due to their case design. All ducts should be laid to a slight fall to facilitate drainage. Dusts Where there is a danger of dusts building up around the motor of a standard axial fan the Bifurcated fan eliminates this problem with its motor out of the airstream. Care must be taken to maintain minimum velocities for the conveying of dusts in the air stream. (If the dust causes a change from standard air density (1.2 kg/m 3 ) please refer to your nearest sales office). Flammable Gases With the additional fitting of a spark minimising impeller track, the fans are suitable for Group 2A and 2B gases. The fan must be mounted outside of the hazardous area. The shaft seal must be correctly maintained. Corrosive Chemicals The Bifurcated fan is suitable for some mild chemicals that will not corrode the galvanised casing or the seal of the motor shaft through the case. Additional protection can be provided by an epoxy paint finish. Please refer corrosive chemicals such as acids and solvents to ourselves where we can advise on the suitability of the fan. 4
JM AEROFOIL - BIFURCATED SPECIFICATION Motors Constructed from aluminium as standard with special stud and pad mounting fixings. Suitable for horizontal through to vertical shaft operation. Supplied IP55 Insulation is Class F, with Class F temperature rise. Bearing lubricated with wide temperature range grease, relubricatable or sealed for life bearings dependant on size. The motor is cooled by ambient air drawn into the tunnel which extends to the side of the casing, and is suitable for continuous operation for up to 4 C ambient. Speed Control Woods do not offer speed control for the bifurcated fan by conventional electronic or autotransformer speed control. This is due to the motor construction. For inverter drive applications enquire at Colchester. Starting Standard three phase motors of 5.5 kw outputs and above are usually provided with Star/Delta starting connections. Electrical Supply 23 V +1/-6 %; 5Hz; single phase (1φ )* 4 V +1/-6 %; 5Hz; three phase (3φ ) (6Hz and other voltages are available on request). Casings The JM Aerofoil Bifurcated design is generally similar to a normal axial flow fan, but the motor is isolated from the main air stream by a tunnel which extends to the side of the fan casing. The casing of the 15mm to 5mm diameter sizes have an enlarged bore located around the motor to permit adequate cross sectional area for air to flow round the motor tunnel. The 63 mm to 1 mm diameter sizes have casings of constant diameter. Impellers Small Bifurcated 15 mm - 3 mm Cast aluminium silicon one piece with fixed aerofoil section blade. Large Bifurcated 4 mm - 1 mm High pressure die and clamp plate, with equally spaced, fully adjustable, high pressure die cast section blades. All rotating aluminium components are X-ray examined prior to machining to ensure quality. Balanced to BS661 Part 1 197 (ISO 194-196) Grade G6.3. Ancillaries Guards to comply with BS4 Pt 5. and draft ISO standards. 2 speed switch for Delta/Star reconnection Silencers Mounting feet for both horizontal and vertical mounting Matching Flanges. Flexible Connectors. Air Operated Dampers.** Bellmouth inlets. ** Vibration Isolators. Finish Standard: The fan casing, mounting feet, matching flanges and guards are all hot dipped galvanised after manufacture, (in accordance with BS729:1971). Motors, aluminium self finish, or painted to motor manufacturers specification. Non Standard: For more corrosive conditions the fans can be treated at extra cost with an epoxy paint finish. The maximum temperature for this finish is +12 C (continuous). Additional Extra Features Epoxy Paint System Finish. Non Standard Voltages. Motor Thermistors. Motor Thermostats or Thermal Switches. Motor anti-condensation Heaters. Spark Minimising Feature. * Available 15 mm - 3 mm only ** Available 4 mm - 1 mm only 5
JM AEROFOIL - BIFURCATED FORMS OF RUNNING, TEST METHODS & QUALITY SYSTEMS The direction of airflow through the fan and the mounting position are defined as the Form of Running. Woods only offer Form B running bifurcated fans as Form A fans have a marked loss in performance. 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 duct nameplate. Single Stage Form B Form BU Form BD Two Stage For Two Stage selections, please refer your enquiry to a Woods representative. Form B/B Testing The air and sound performance data has been measured by the latest version of British and International Standards:- ISO 51 category D (fully ducted) method for testing air performance (supercedes BS4 Pt1 19). BS4 Pt 2 195, method of noise testing. It is essential, when comparing fan performances, that the same installation category and test standards are used at all times. Acoustic Data The sound levels quoted are based on tests carried out under the Woods certified laboratory conditions. Using the spectrum corrections stated on each performance chart, an unweighted sound power spectrum can be obtained for the fan. Motor Ratings The motor ratings, starting, full load currents and speeds refer to the maximum output of the motor. When the impeller does not require the full output, the power and current will be less than the maximum quoted. Anechoic Test Suite at Colchester Quality Systems Woods Air Movement are committed to Quality Assurance. Registered to BS EN ISO 91.94, N.A.T.O. Quality Standard AQAP-1 Edn 3. BS EN ISO 91.94 registration means that Woods design is quality assured as well as the manufacture. Our commitment to Quality Assurance doesn't stop with the hardware. The performance data comes from standard tests carried out in Woods own laboratory which is BSI (CAME) and AMCA accredited. A JM Aerofoil Bifurcated fan can be bought with the confidence, as with all Woods products, that it will achieve the published performance data and match the assured quality. All the Woods JM Aerofoils are fitted with IP55 motors as standard, and come with a 2 year guarantee. 6
