Description
The ALPHA is the largest High Volume Low Speed (HVLS) fan in our range with an impressive maximum diameter of 7.3 metres. Available in a 3-phase input with a customisable blade size range of 5 metres to 7.3 metres this is the cooling solution for large commercial and industrial facilities. German NORD-designed motors and gearboxes for long life, quiet operation, and serviceability. HVLS fans produce a much greater cooling effect than smaller higher speed options while consuming less power, generating less noise, and requiring fewer overall fans.

Check the status and quantity to ensure you have the user manual, and all these parts:
*Please note that different mounting fixtures are used for either: H Beams, concrete beams, rigid frame beam, refer below:
Installation Precautions
The maximum weight of the fan is about 125kg and the maximum torque is about 260N m. The clearance from the fan to the roof (no matter what the roof structure) is the distance between the location of the lowest part of the fan (nearest to the ground) and the installation of the upper connecting frame of the fan.
For an inclined roof, the required distance should be moved to the tip of the blade, otherwise, it may cause the blade tip to collide with the roof or affect the smooth flow of airflow because the distance between the roof and the blade is too short. Overall, it is necessary to maintain reasonable fan blade and roof space to ensure proper air flow.
With the increase of fan speed, the fan blade will move upward along the diameter of a certain angle, increasing the fan coverage area. Therefore, all obstacles that may be encountered within the radius of the fan and between the horizontal height of the fan’s static position and the ceiling should be measured before installation, ensuring that the fan has an appropriate clearance in all directions when running (see below diagram). Ensure that the fan and the existing facilities of the building (horizontal and vertically) have a clearance of at least 300mm.
Mounting Installation Methods:
Each type of building structure requires a specific mounting bracket, the Zephyr ALPHA fan can only be installed with the included mounting equipment onto H-Beam, Rigid frame beam or Concrete beam structures. For buildings with a different installation structure, an additional set of brackets may need to be customized, please consult Zephyr.
Warning
- Verify with the contractor, building owner or structural engineer to ensure that the building structure is sound and adequate to support Zephyr products before installation.
- Ensure to take accurate height measurement of both the structure beam and blade level.
- Ensure to check if the power supply is correct on site.
Installation Tools
Please ensure you at least have the following tools:
- Leveling instrument
- Cutting pliers
- Wire stripper
- Lifting device(Scissor lift or scaffold )
- Pliers
- 4 sets of tighteners(or turnbuckle screws)
- Phillips head screwdriver
- Flat head screwdriver
- Tapeline
- Marking pen
- Hand electric drill with M4.2 bit.
- Out hexagonal wrench: 8mm/10mm/14mm/16mm/17mm/24mm
Note: A hammer drill with 12mm drill bit will also be required when connecting to the Concrete beam.
Installation Guide
Step 1: Installing onto the building
H-Beam
- Connect to a steel H-Beam with the adjustable mounting bracket set, (the fan can be easily clipped onto on any steel H-beam, without changing the steel structure).
- The device can be adjusted according to the width of the beam (170mm-340mm).
Concrete Beam
- Connect the mounting device by fixing the expansion bolts onto the concrete beam, the mounting device can be adjusted to the width of the beam (240mm~420mm).
Rigid Frame Beam
- Connect the mounting device by threaded rod onto the rigid frame beam.
- Cut the threaded rod into 4pcs based on the height of the rigid frame beam. The device can be adjusted according to the width of the beam (80-400mm).
Cardan Joint Installation
- For sloped beams use the cardan joint to install the Zephyr fan, this allows the fan to freely oscillate and self-level in conjunction to the slope angle.
Step 2: Installing the extension rod
- Connect the ends of extension rod with the Cardan joint and drive device with the bolts (please note that the length of the extension rod is customized according to site parameters, this will need to be cut on site).
Step 3: Installing the drive
- Fix the extension rod onto the drive device with the supplied bolts (please note that the drive device is preassembled as a singular unit, the drive device is heavy and will require 2-3 people to lift and install).
Warning
- Do not remove the oil plug until the fan is properly mounted.
- If the oil plug is removed before the fan is mounted, oil in the gear box reducer may spill out.
Step 4: Connecting to power supply and wiring
- The wire conduit layout should be done in accordance to site parameters and respective state, industry Australian standards and legislation.
- Before wiring, please make sure the power is off . Then connect to the power supply. If the site power supply is three phase delta type. Connect motor wire first then connect the electric wires to the control box.
Warning
- Do not connect the power supply to the drive directly.
Wiring diagram
Step 5: Installation of security cables
Each fan has four steel wire ropes. Please ensure that the angle between each steel wire and the drive device is approximately 45 degrees, any variation in the angle will affect the strength of the steel wires. Please adhere to the below guidelines:
Method 1: Installing with turnbuckle
- Use four safety cables per fan, with three clamps per rope. (One clamp for the site structure, two clamps for turnbuckle).
- Use the closed-end of turnbuckle to fix the steel wire to the building structure, and use the open end of the turnbuckle to fix the steel wire to the safety rings of the fan.
- CAUTION: It is important to avoid wrapping the steel wire around any sharp corner. Although the external force used to fix and balance the fan is very small, the continuous running of the fan may cause fatigue damage to the steel wire rope over an abrasive surface.
- Attach the steel wire to the building first, install one clamp per wire and tighten.
- Attach the steel wire to the closed-end turnbuckle, and use the open-end of the turnbuckle to fix onto the safety ring of the fan. Install two clamps per wire.
- Using the turnbuckle, tighten each steel wire rope gradually and use a leveling instrument to make sure the drive device of the fan is at a vertically level position.
Method 2: Installing with tightener
- Attach the steel wire to the site structure first, install one clamp per wire and tighten.
- Attach the steel wire to the safety ring of the motor frame, install two clamps per wire, do not tighten the screws immediately.
- Use the tightener to tighten each steel wire rope gradually, while using a leveling instrument to ensure that the drive device of the fan is at a vertically level position. Lock the clamp screw near the motor of each steel wire, loosen the tightener and lock the end clamp screw.
CAUTION
- Ensure each wire rope has the same tightness after installation.
Step 6: Safety Cable
- The wire rope is wound around the site roof beam structure and connected with the motor frame by extending through the inner cavity of the rod and forming a closed loop.
Step 7: Empennage installation to fan blade
- Insert the empennage to each airfoil blade and fix it by using the two tapping screws.
Step 8: Fan blade installation
- The fan blade is pre-installed onto the fan wheel hub, simply insert the fan blade onto the blade pins and fix with two bolts per blade. The correct direction of the blade installation should be the blade upwind surface(thick round part of the blade) the highest, blade leeward surface downward as per the diagram below:
- Attach the 6pcs safety retainer on the top of the fan to connect each blade together, as seen in the diagram below:
- CAUTION: Tighten the outside bolts first, then tighten bolts along the top of the fan.
Step 9: Hub cover installation
- Place the bottom cover close to the hub and tighten it with the included bolts.
