AXIAL FLOW FANS GENERAL INFORMATION
IntroductionThis section of the catalogue details the performances of a wide range of axial flow fan types as follows:
The above fans range in diameter from 315mm to 2000mm.
The curves shown on pages C-12 to C-24 show a range of performances for the AP series of direct-driven axial flow fans in Type D Installation (see below). The other fan types listed above incorporate casings or housings that impact on their performance result. The Intelligent Ventilation Product Selection Program will produce performance curves for these other fan types that have automatically taken these losses into account.
Test StandardsThe International Standards Organisation (ISO) achieved a standardised fan test code with the publication of ISO5801:1997. This Standard replaces BS848:Part 1, 1980 upon which it was based.
Fan performances for the Elta Fans 1000 Series diameter have been aerodynamically tested to BS848:Part 1, 1980 and the Elta Fans 1400 and 2000 Series to ISO5801:1997. All three series have been tested to BS848:Part 2, 1985 for sound performance.
The main difference between the above Standards and those they replaced, is the installation Types A, B, C and D such that, if a fan unit is designed for use in any one of these arrangements, the variation in performance should be established and shown.
Both BS848:Part 1, 1980 and ISO5801:1997 reflect the latest understanding of measuring techniques and accuracy in fan performance testing.
If the same fans were tested to pre-1980 airflow and noise Standards and then to the latest Standards, different performances would be obtained. The results from the later Standards give differences of as much as:
• -5% in volume• -10% in pressure• -5% in efficiency• +2 to 6dB in noise
These differences should be borne in mind when making comparisons of fans tested to the different Standards, as they are the result of the test method and not the product.

AXIAL FLOW FANS GENERAL INFORMATION
Performance VariationsThe achieved fan performances can differ from the test performances shown on the subsequent pages due to two main effects:
a) The encroachment of irregular or abrupt changes within the system close to the fan. If good design practice is followed, then the fan will receive nearly uniform air into its inlet, and discharge its airflow in an almost ideal pattern. If this is achieved the fan will perform to its expected level.
Reference to the “Do’s and Don’ts” tips on page P-1 will assist in avoiding pitfalls. The advice in “Do’s and Don’ts” applies to the application of all fans, not just axial flow fans.
b) Changes to the internal elements of the fan: e.g. large junction boxes on motors, belt drive stacks or excessive blade tip clearances.
Forms Of RunningThe main series of tests were conducted on Form B units and comparative tests were carried out on Form A units. Resultant performance differences occur mainly on the outlet side of the fan, as correct practice should result in the presence of a duct or inlet cone on the fan inlet.
Down-Stream Gudie VanesA normal axial flow fan, whilst being very economical and compact, imparts motion to the air in an axial and rotational direction. The rotating component is usually called ‘swirl’. The swirl component eventually dissipates, but by using Down Stream Guide Vanes (DSGV) it can be converted to more useful static pressure. Static pressure increases of 10%-25% can be achieved with DSGVs, thus giving an increase in efficiency. As the work is done after the air leaves the fan, DSGVs do not require any additional fan power. They are most effective at pitch angles over 20° and produce small increase in sound levels of 1-2dB.

AXIAL FLOW FANS GENERAL INFORMATIONMulti-Stage Axial Flow Fans
Multi-stage axial fans with contra-rotating impellers can be supplied up to 2000mm diameter.
A two-stage assembly develops approximately 2.4 times the pressure developed by a single-stage fan and increases the overall sound level by 8 to 10 dB.
To select a contra-rotating axial fan from the curves in this catalogue, divide the specified static pressure by 2.4 and then select as though it were a single-stage unit. The kW derived is for one stage only and the noise level will be 8 to 10 dB higher than the single-stage fan.
NOTE: Reference should be made to Elta Fans for complete selections of these fan arrangements. Alternatively selections can be made using the Intelligent Ventilation Product Selection Program.
Elta Fans Impeller RangeThe Elta Fans impeller ranges included in this catalogue have harnessed the latest technology in axial impeller design, resulting in enhanced pressure development, energy efficiency and reduced noise levels.
There are three main ranges: -
Elta Fans 1000: 315 to 1000mm diameter using 150 or 250mm diameter hubs. Elta Fans 1400: 800 to 1400mm diameter using 255 or 350mm diameter hubs. Elta Fans 2000: 1250 to 2000mm diameter using 400 or 550mm diameter hubs.
For performances beyond those detailed in this catalogue, and for applications such as mine and tunnel ventilation, please refer to our sales engineers for information.
Impeller SpecificationsBlades
The blades have been designed for optimal performance, for both aerodynamic needs as well as noise characteristics. They are available in a range of materials as shown below:
Impeller RangesThe stress limits of the blades vary from one material to another and simplified criteria are incorporated on the curves. However, if selecting fans using the Intelligent Ventilation Product Selection Program, you may find solutions where 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.
HubsAll hubs use Elta Fans TECH-LOCK® taper bushes as standard. 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.
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 2000mm diameter. If contra-rotating fans of a larger diameter are required please refer to our sales department.

AXIAL FLOW FANS GENERAL INFORMATIONStandard 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 before leaving our facilities to ensure vibration-free running.
Fully-adjustable Blades
All impeller pitch-angles are fully adjustable. For the Elta Fans Range, up to size 1400, the required blade angles are set on jigs but sizes up to 1000 may also be set utilising the graduated scale at the root of each blade. For the Elta Fans 2000 Range, pitch angle setting is by protractor.
Operating Speeds & TemperaturesImpellers installed for O.E.M. applications are submitted to the vibration, cyclic torques and temperature cycles that prevail within the item of equipment. It can therefore be misleading to state maximum conditions unless the full operating environment is known, as all the above points can be inter-related.
The table below should be used as a guide only. For accurate figures use the Elta Fans Product Selection Program.
Reversal Of AirflowAirflow direction can be reversed on fans fitted with three-phase motors by simply reversing the direction of rotation.
The impact on performance in reverse rotation approximates to:
Airflow reduction -30% Pressure reduction -55% Power reduction -25%
Truly ReversibleEqual volume flow in both directions can be achieved by blade reversal procedures carried out when the impeller is being assembled.
The impact on performance when compared to standard performance approximates to:
Airflow reduction -15% Pressure reduction -25% Power reduction -20%

AXIAL FLOW FANS GENERAL INFORMATIONConstruction
All axial fan casings are rolled and flanged from either pre-galvanised sheet or heavy-gauge mild steel that is hot-dip galvanised after manufacture. All hot-dip galvanising of axial flow fan products is to AS/NZS4792:2006 and is the standard finish on the fans larger than 800mm diameter and their accessories. The standard casings enclose the impeller and motor completely. 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 50mm sight hole is fitted on smaller fans. An inspection hatch is available on the smaller fans.
Flameproof or increased-safety motors are wired to the outside of the case and left with a generous length of lead. This is so the client can connect to their own terminal box in accordance with the requirements for the particular hazardous zone.

AXIAL FLOW FANS GENERAL INFORMATION
Smoke-Spill ApplicationsSmoke-spill fans have to be tested to Standard AS4429:1999 and EN12101-3:2015 to conform with the requirements of AS/NZS1668.1:1998. To meet the Standards Elta Fans conducted an extensive series of tests covering both airflow and temperature. The airflow tests for sizes 315mm to 1000mm diameter conformed to BS848:Part 1, 1980 and to ISO5801 for sizes 1.0m to 2.0m. The temperature tests were conducted in accordance with AS4429:1999, although the 300°C tests were extended from 0.5 hours to 2 hours to ensure we met the needs of some specifications.
The outcome of the series of tests is that we can supply fans ranging in diameter from 315mm to 2000mm at speeds as high as 2 pole depending on size and, for both 50 and 60Hz supply that fully comply with the Standards in all respects.
The following conditions can be met:
Discharge Damper Fail-open Latching
An additional requirement of the Standards relates to the function of the discharge dampers in unsprinklered buildings. Elta Fans has met the requirements with two designs, the first being a manual release type requiring manual closing after the fan has been run. These may be used for dedicated smoke spill fans. The second design, an electro-mechanical arrangement, permits the shutters to close automatically after the fan stops. These are recommended for use on dual-purpose ventilation/smoke-spill fans. Elta Fans has provisional patents for both designs.
For advice on Smoke-Spill wiring requirements, refer to the above Standard.

AXIAL FLOW FANS PERFORMANCE DATA
Introduction To Performance Data Graphs The Elta Fans Impeller data shown on pages C-12 to C-24 in this edition of the catalogue has been condensed to ensure it remains accurate and current. The graphs show the AP series of direct-drive axial flow fans in two impeller configurations for any one fan size/speed combination. These graphs include the impeller capable of developing the highest static pressure and an impeller with fewer blades that develops less pressure. The second configuration would generally be a cheaper, quieter and, possibly, a more efficient selection.
The performance curves in this section show the free-field sound pressure levels under spherical radiation conditions in dB(A), 3 metres away, on the outlet side of the fan.
Selecting from these graphs provides a guide only, albeit an accurate one, to possible selections. Basic noise level data as well as indicative power absorbed figures are incorporated on the graphs. The final selection for any particular fan is best achieved by contacting the nearest Elta Fans sales office, or by using the Intelligent Ventilation product Selection Program. The Program will show other possible impeller combinations between the two illustrated in this catalogue, and will provide full performance information including airflow, pressure, noise levels, absorbed power as well as complete dimensional information.
To ensure the information we provide our customers on the Elta Fans Impeller range is up to date and reflects new product developments and improvements, performance data is constantly being updated. This updated information is included on the Intelligent Ventilation Product Selection Program and Elta Fans website, the data contained in this catalogue is correct at the time of print.

The example shown here is for a 630mm axial flow fan (AP Series) running at 24 rev/sec in Type D installation (fully ducted). It illustrates a duty of 2.5 m³/s at 150Pa static pressure.
1 Diameter of fan: 63cm (630mm)
2 Fan speed: 4 poles (24 rev/sec)
3 Number of blades: 5
4 Hub diameter: 150mm
5 Air volume flow: 2.5m³/s 6 Static pressure: 150 Pa No correction is required as the curve is plotted for Type D installation.
7 Duty point: The point where the air volume flow line intersects with the static pressure line. 8 Estimated sound: 66dB(A) Estimated sound is the value (in the circle) which is the closest to the duty point.
9 Blade angle setting: 20° The blade angle is determined by interpolating a curve between the two defined blade angle curves either side of duty point. (Solid blue curve) 10 Fan impeller absorbed power: PR = 0.65kW. The fan impeller power is determined by interpolating a curve between the two defined AkW curves either side of the duty point (broken black curve). 11 Dynamic pressure: 39Pa Dynamic pressure is the Y-axis value where the dynamic pressure curve intersects the vertical line between airflow and duty point.
The Fan Total efficiency can be calculated by using the formula: where:
qv = volume flow, m³/s ptF = fan total pressure, Pa
= psF + pdF
PR = fan impeller power, kW
