FAN & BLOWR CNTRIFUGAL FANS INTRODUCTION GNRAL PRODUCT RANG FANS BY FANTCH - INTRACTIV PRODUCT SUIT SLCTION PROGRAM PRFORMANC CONSTRUCTION The Fan & Blower range of centrifugal fans is marketed to the air conditioning industry throughout Australia by the Fantech Group and its agents. The Fan & Blower Company is an Australian company, wholly-owned by the Harvey Group, who have been steel fabricators since 1895 in NSW, and fan manufacturers since 1968, in Parramatta NSW. The wide range of products includes:- backward-inclined centrifugal fans mill exhaust centrifugal fans high pressure blowers and vacuum producers turbovane radial blade fan special purpose-designed fans when the application demands. The data in this section of the catalogue permits users to make quick selections and to determine the space required by the fans, but it is primarily intended to be a supplement to the Fans by Fantech - Interactive Product Suite computer selection program. The program has been designed for Windows 95 and later computers. The computer program is specific to the backward-inclined single and double-width centrifugal fans used in the air conditioning, ventilation and dust control industries. It enables users to select the fan and get a print-out of the performance curve and dimensions of the selected fan in the required handing. The computer program is limited to showing handings ACW0, ACW90 and ACW1, but others can be provided. A copy of the CD is available on request. The data given here, and in the computer selection program, is based upon tests conducted in accordance with BS848:Part 1, 19 for air flow and to AS1217-Section 3.4, 1972 for noise. Backward-inclined Centrifugal Fans Both the Laminar (L) and Aerofoil (AL) rotors use the same fan casing. The L blade is a backward-inclined blade. The AL blade has a backward-inclined hollow die-formed aerofoil section. Both designs have a non-overloading power curve. Apart from the blades, the rotors are similar in construction, using the same backplate, hub and inlet spinning. Rotors are balanced, both statically and dynamically, in an electrodynamic balancing machine to the balance quality grade G6.3. Fan shafts are machined from Grade CS1030 bright steel conforming to AS1443-1983 and are designed such that the first critical speed of the shaft is equal to, or greater than, 130% of the operating speed. Re-greasable, single-row, deep-grooved ball bearings in pillow block housings are fitted as standard, or, where the duty warrants, grease-lubricated, double-row ball or roller bearings in grease-relieved split plumber block housings. The casings are fabricated from fully-welded, hot-rolled steel sheet plate conforming to AS1594-1992. -12 CNTRIFUGAL FANS; SWSI & DWDI
FAN & BLOWR CNTRIFUGAL FANS INSTALLATION HANDINGS SPCIAL APPLICATIONS ANCILLARY QUIPMNT The amount of space required around the fans must be considered to avoid uneven air flow and pulsations and to ensure the fan will be able to work to its full potential. Generally this necessitates leaving a space equivalent to one impeller diameter between the fan inlet and a wall or baffle. In a situation where two or more fans are mounted in parallel, then a space equivalent to two fan diameters must be left between fan inlets that face each other. If that amount of space cannot be provided a baffle must be erected between the fans, and the possibility that the fans may not operate to their full potential must be considered. The full range of handings for both single and double-width units is available. The fans can be designed to handle air at elevated temperatures continuously. The treatment to the fans in these situations will differ according to whether it is a single or double-width fan but both can be adapted to suit the application; double-width fans are generally limited to 120 C when built to arrangement no. 3. The fans can be provided with the following:- access panel inlet screens drilled discharge angle flanges(spigot connection is standard) matching angles vibration isolators drain connection split casing variable inlet vane control heat slinger and guard spark-resistant construction stainless steel or aluminium(standard construction is mild steel) non-standard finishes(prime coat of grey, zinc phosphate is standard) inverter speed controllers attenuators OTHR PRODUCTS General information on the Mill xhaust, High Pressure Blowers and Vacuum Producers is given on page -20: refer to sales engineers for more specific selection and dimensional information.

CNTRIFUGAL FANS; SWSI & DWDI FATURS Construction Casings are welded mild steel, with a prime coat of zinc phosphate, colour grey. Impellers are of welded construction and can have backwardinclined laminar (L) or aerofoil (AL) section blades. Shafts are of bright steel conforming to AS1443-1983. Motors Type - squirrel cage induction motors. lectricity supply - single or three-phase, 50/60Hz. Bearings - ball. See pages N-3/4 for details on these motors. Motors are selected to suit the application and can be provided with 2-speed windings if necessary. In addition, motors to meet explosion-proof, flameproof, dustproof or similar special needs, can be fitted. Speed-controllable using frequency inverters. Internal Thermal Protection Thermisters can be provided if necessary. Testing Air flow data is based upon tests conducted in accordance with BS848:Part 1, 19 and noise data to AS1217-1972. Special Features Both direct or belt-driven units to suit a wide range of applications can be provided. Selections The graphs shown on page -15 are quick-selection graphs only and are designed to give a close indication of the fan size required to perform a specific duty. Detailed selections can also be made with the Fans by Fantech Interactive Product Suite or by referring to our sales engineers for a written quotation. Wiring Diagrams See page M-6, diagrams DD 1, 2, 3. ANCILLARY QUIPMNT Refer to the ancillary equipment list on pages I-1, J-1 and L-1. HOW TO ORDR Before production can commence the following information is essential:- performance required air temperature, if other than standard fan size and type; eg. SWSI or DWDI impeller type; eg. backward-inclined laminar (L) or aerofoil (AL) fan handing discharge angle position of the drive motor degree of vibration isolation electricity supply type of motor; eg. standard, explosion-proof, flameproof, dustproof, etc. ancillary equipment (refer to pages I-1, J-1 and L-1) finish, if other than standard any special identification markings Special Note Refer to Fantech Product Selection CD-Rom or your Fantech Representative for detailed selection. -14 CNTRIFUGAL FANS; SWSI & DWDI FANTCH 2008
