1 Axial Flow Fans

2 Section 4 Fläkt Woods offers a wide range of axial flow fans for general air movement and special applications such as emergency high temperature smoke extract and pressurisation. ATEX fans for explosive atmospheres and multistage options for increased pressure development. All fans are tested to the latest internationally recognised standard IS05801 Part 1 (1997), installation category D (AMCA approved) for aerodynamic performance and BS848 Part 2 (1985) for acoustic performance. Coupled with the above fan diameters, the adjustable pitch Aerofoil impeller gives the exact performance required, with a non overloading fan characteristic. Axial Fans - Section 4

4 Aerofoil - JM Aerofoil Section 4 Eleven sizes are offered from 315mm to 1000mm diameter. Volume flows of up to 19m 3 /s Static pressures up to 800 Pa High energy efficiency Sizes 31JM - (315mm) to 100JM - (1000mm). Larger sizes up to 2800mm diameter are also available. Please enquire. Fan Performance All fans are tested to the latest internationally recognised standard IS05801 Part 1 (1997), installation category D (AMCA approved) for aerodynamic performance and BS848 Part 2 (1985) for acoustic performance. Coupled with a wide range of fan diameters, the adjustable pitch Aerofoil impeller gives the exact performance required, with a non overloading fan characteristic. Impellers A unique high efficiency aerofoil section blade with a purposely smoothed hub and clamp plate for adjustable pitch angle availability. The Fläkt Woods impellers are all high pressure die cast to offer thin aerofoil sections for low generation of noise. Every cast aluminium component is X-ray examined using Real Time Radiography inspection prior to assembly. The maximum pitch angles shown allow for speed control by frequency inverter (3ph only). Motors Low installed noise levels Motor protection IP55 All casings are hot dipped galvanised Overheat protection is fitted as standard Inverter controllable All motors are totally enclosed air stream rated class F insulation. Constructed from aluminium or cast iron as standard with special T slot or pad mounted fixings. Single speed motors are suitable for speed control by voltage regulation where indicated. Three phase motors are suitable for use with frequency inverters. Two speed motors where available are pole change type. Suitable for horizontal through to vertical shaft operation. Supplied IP55, with removable drain plugs. Sealed for life bearings lubricated with wide temperature range grease. The BT, CT, F22 and PM112 motors are all fitted with overheat protection thermostat as standard. D motors are fitted with Thermistor OHP. These motors are suitable for inverter speed control down to 20% of full speed. Section 4 - Aerofoil - JM Aerofoil Electrical Supply V / 50 Hz / 1 φ V / 50 Hz / 3 φ Temperature Range -40 C to 50 C as standard. (All motors are not suitable for starting at temperatures lower than -20 C.) Fans that include BT or CT motors can be continuously operated at temperatures up to 70 C. When these fans are operating in excess of 50 C they should be run at full speed only. Other fans can be operated up to 70 C with appropriate deration of motors. Most standard 3φ fans can be offered for a one off emergency operation at 200 C for 2 hours. Casings JM Aerofoil fans are available in either a long cased form, complete with an externally mounted pre-wired electrical terminal box, or short cased for duct or plate installation. Casings are spun from sheet steel with integral pre-drilled and radiused inlet flanges. The galvanised finish gives a high resistance to corrosion and is ideal for external as well as internal use. Accessories Silencers, Mounting feet, Vibration isolators, Matching flanges, Flexible connectors, Air operated non return dampers, Guards, Bell mouth inlets. Electronic and transformer type speed controllers and frequency inverters. Standards available contact your local Express Distributor for more details. See section

25 JM Aerofoil ATEX Section 4.3 Atex standards now available with the Fläkt Woods JM Aerofoil range. Contact your local Express Distributor for further details on availability. Section 4 - Aerofoil - JM ATEX The high specification Industrial Markets in Europe require high specification products for the hazardous application sector. To support our customers Fläkt Woods can offer ATEX compliance on its JM Aerofoil axial fans and its new Centripal EU range of centrifugal fans. This combined range is considered the widest range available from a single manufacturer. What is ATEX? As from July 1, 2003 the new EU ATEX Directive requires most products to be used in potentially explosive environments to be ATEX compliant. The new directive covers a surprisingly large range of equipment including products used in petro-chemical plants, chemicals, pharmaceuticals, battery rooms, flourmills, grain silos and other areas where a potentially explosive atmosphere may be present. Potential explosive hazards are very common and include gases, vapours, mists and dust. The specific mixture being handled categorises the features each product must include. Who does ATEX apply to? End users have the ultimate responsibility to ensure ATEX compliance and Fläkt Woods can assist in this area. Our website provides much of the information and forms required. Manufacturers OEM s Specifiers Distributors Products installed after 1/7/03 may have to be replaced should they not comply with the ATEX directive. Users must act now to specify the correct product. Fläkt Woods ATEX Compliant Fans Fläkt Woods offers both Aerofoil axial fans and Centripal EU range of centrifugal fans that are all ATEX compliant. We have ensured that all the necessary systems are in place during production to continue ATEX compliance. Fläkt Woods have invested heavily in Engineering design and specification to comply with ATEX. Fläkt Woods fans have been modified in a number of ways including changes to motors, materials, locking systems and conduit systems as well as adapting and revising product guides and operation manuals. Acceptance throughout Europe Having the ability to supply ATEX compliance and by CE marking our fans, Fläkt Woods are able to sell fan products anywhere in Europe without further requirements being applied. This also enables refurbishment of existing installations OEM customers can be confident in using Fläkt Woods products to gain the relevant certification of their products.
