blades vary from one material to another and simplified criteria are incorporated on the curves However if selecting fans using our interactive product selection CD you may find solutions with higher pitch angles are chosen these selections are quite acceptable It should be noted that as we are constantly reviewing the materials we use these limits may be extended Hubs All hubs use Fantech TECH LOCK taper bushes as standard with one exception The bush ensures ease of fitting and removal of the impeller from the motor shaft should adjustment of the pitch angle cleaning or repair of the impeller prove necessary The exception is for bores above 65mm and 85mm diameter for the 400mm and 550mm diameter hubs respectively In these cases we supply impellers with simple through bores Fixings All impellers are assembled using high tensile zinc plated set screws and self locking nuts Handing Right and left hand blades are available enabling the selection of contra rotating or multi stage axial flow fans up to 1400mm diameter If contra rotating fans of a larger diameter are required please refer to our sales department Standard Material GRP blades will be supplied for normal clean ventilation applications as standard except where otherwise specified or where local regulations prohibit their use Balance The balance of all impellers is carefully checked to ensure vibration free running Fully adjustable Blades All impeller pitch angles are fully adjustable For the Elta Range up to size 1400 the required blade angles are set on jigs but for sizes up to 100 may also be set utilising the graduated scale at the root of each blade For the Elta 2000 Range pitch angle setting is by protractor AXIAL FAN CASINGS Construction All axial fan casings are rolled and flanged from heavy gauge mild steel and hot dip galvanised after manufacture The standard casings enclose the impeller and motor completely and weatherproof external terminal boxes are standard The motor is wired into the external terminal box through flexible terminal weatherproof conduit and a separate earthing screw is provided An inspection hatch is standard on fans 1000mm diameter and over a 50 mm sight hole is fitted on smaller fans An inspection hatch is available in the smaller fans on request Flameproof or increased safety motors are not normally wired to the outside of the case so the client can connect directly to the terminal box in accordance with the requirements for the particular hazardous zone Direct drive AP Series 315 to 2000 mm diameter The entire range can be provided in a wide choice of speeds to meet an extensive range of performances and applications If a speed or duty you require is not shown please contact our sales engineers for assistance In general all flameproof or special application motors can be fitted if required Direct drive APV Series 315 to 2000 mm diameter The full range of sizes and speeds can be provided as direct drive APV units for applications where the fan must be installed vertically The casing is designed with integral outriggers to facilitate vertical mounting Direct drive APS Series 315 to 2000 mm diameter For smoke spill applications we can supply fans up to 2000mm diameter fully tested to meet the Australian Standards AS NZS1668 1 1998 and AS4429 1999 See below for more information Belt drive APB Series 315 to 2000 mm diameter The full range of sizes and speeds can be supplied as belt driven APB units for applications where the motor must be out of the air stream When selecting these fans allowance for the additional pressure loss caused by the drive arrangement must be taken into account as follows Open belts no extra pressure loss Sealed belt guard add 5 to the design pressure Bifurcated BFA Series 400 to 1250 mm diameter This range is available in a wide choice of speeds Bifurcated axial flow BFA fans are designed for handling toxic noxious abrasive and hot gases and can be used as an alternative to the APB belt driven range The maximum air temperature the standard bifurcated fan can handle continuously and without special treatment to the impeller and motor is 100 C for an aluminium impeller or 70 C for GRP Bifurcated fans can be specially built to accommodate temperatures of up to 200 C continuous for sizes up to 1250mm and 250 C up to sizes 630mm For this type of application it is essential the fan be mounted in normal ambient conditions that the central motor tunnel be aligned vertically and that the motor have Class F insulation and equivalent lubrication of the bearings Refer to us if the fans are to handle higher temperatures or the motor tunnel is not vertical When selecting these fans the following allowances must be made to the duty to compensate for the central shroud Sizes 400 to 560 1 0 pdF Sizes 630 to 1250 0 7 pdF Square Plate SQ Series 315 to 1250 mm diameter This range is available in a wide choice of speeds All square plate fans irrespective of the direction of the air flow incorporate a bell mouth entry the direction of air flow must be nominated at the time of order Generally all flameproof or increased safety motors can be fitted if required When selecting these fans installations Type A or B must be used The square plates are of heavy gauge steel with a bell mouth

    corrections are shown below Octave Band Centre Frequency Hz 63 125 250 500 1k 2k 4k 8k A frequency weighting corrections 26 16 9 3 0 1 1 1 The A frequency weighting suggests that if a tone of 40 dB is played at 1000 Hz a 40 dB tone played at 63 Hz would sound 26 dB quieter or be 14 dB A Due to its simplicity and convenience the A frequency weighting has become popular and is now used for many different noise sources at different levels In fact most legislation regarding noise is written using dB A s in addition nearly all manufacturers of fans and other noise generating machines quote their noise levels in dB A s at 1 1 5 or 3 metres assuming spherical distribution It is therefore important that we understand the A frequency weighting and how dB A s are calculated Information on Fan Noise Test Standards Where noted in the product data pages within this catalogue fan noise levels are tested to BS848 Part 2 1985 Fans for general purposes Methods of noise testing This test standard describes methods that may be applied to calculate the sound power level of fans That is the In Duct method the Reverberant Room method and the Free Field method The sound pressure level of a product is measured using one of these test methods A calculation is then used to convert the measured sound pressure levels to sound power levels A Cautious Word on the use of dB A Levels The dB A sound pressure level is used almost universally to describe the noise level of many items of noise emitting machinery However published dB A sound pressure levels should be used for comparative purposes only they are not designed to reflect actual installed noise levels The assumptions that are used to calculate the dB A are rarely replicated in real life situations and therefore published dB A values will not necessarily represent the actual noise levels that may be experienced on site In order to determine the actual dB A sound pressure level that may be expected from an installation an acoustic analysis of the system using sound power levels and taking into account the surrounding acoustic environment should be performed Calculating dB A Noise Levels Published dB A or A frequency weighted sound pressure levels are theoretical values These are in fact calculated from the sound power level data and are quoted at a specified distance i e 1 1 5 or 3 metres For example using the Fantech model AP0804AP10 23 duty 7000 l s 80 Pa inlet side by applying an A frequency weighting correction to the fan sound power levels for each frequency and then logarithmically adding the values from left to right the resultant overall sound power level for this unit will be 98 dB A A further calculation is required to convert this value from the A weighted sound power level to an A weighted sound pressure
