Wheel Technology

1. Unique and Innovative Design

• The centrifugal wheel specially made for rooftop fans in all-aluminum construction

• Innovative design based on the advanced foreign concept of full control over flow passages

• Leading-edge products in efficiency and sound

• Wide performance range of high efficiency and non-overload

2. Internationally Advanced Process Adopted for Better Alignment with Flow Field Characteristics

• Flow passage components formed by spinning not by traditional process

• Blades formed by punching to ensure quality

• Dedicated fixtures and tools to ensure the precise mounting position of blades

3. Carefully Selected Materials, Suitable for Smoke Removal and for Use in Coastal Regions

• The strength made for a minimum of 200% of the highest running speed to perform the smoke removal duty

• Resistance to neutral salt spray for wide use in coastal regions

• Rigorous tests for trust worthy performance

4. 4th Generation of Wind-Surfer Wheel

• Continuous improvement for better performance

• Higher energy efficiency

• Lower sound for quieter operation

5. Light Weight and All-aluminum Construction with Explosion Proof Properties

• Metallic feeling and top-notch appearance

• Light weight, weighing only 1/3 of traditional products

• Spark A spark resistance construction, aluminum housing and aluminum wheel and aluminum inlet cone (AMCA99-10)

General Features

1. Upblast exhaust:

Reduce consistence of contamination, automatically separate and collect the liquid contaminated material to keep the roof clean.

2. Independent Motor Chamber: Super Long Service Life

• Drive mechanism located in an independent chamber to have zero contact with the airstream

• Use for exhaust of air containing volatile engine oil, cooking fumes, dust and organic solvent

• Great reliability and expected service life of over ten years

• Fresh air shall be taken into the motor chamber to cool down the motor. The air shall be directed through the clearance under the motor cover.

3. Patented Appearance Design for Practical Beauty 

• Smooth and elegant appearance design with fine manufacturing process

• Silver housing of metallic feeling that easily matches different colors of buildings

• Buildings added a streak of modernity and nobility

4. Light Weight: Especially Suitable for Rooftop of Light Gauge Steel Construction

• Load on the rooftop reduced with less investment in steel

• Housing and wheel constructed of aluminum alloy

Technical Information

1. Quality Standards

The fan has designed according to AMCA design procedure, The fan is certified in according with UL 705 standard. The products are produced within very control procedure following ISO 9001, ISO14001 and ISO 45001.

2. Fan Type

Fan shall be rooftop upblast centrifugal exhaust type and the drive type shall be direct drive or belt drive. The wheel shall be made of aluminium backward inclined centrifugal wheel, and shall include a wheel cone carefully matched to the inlet venture for precise running tolerances. The wheel shall be statically and dynamically balanced to Level G2.5 as per AMCA204 standard.

3. Fan Housing

The fan housing shall be constructed of heavy gauge aluminium alloy panel with a rigid internal support structure. The wind band support structure shall be strong enough to protect the fan from wind load, the internal structure shall be water tight during heavy rain or snow melting. The exterior colour of the fan shall be silver white (Option: epoxy coating, colour RAL9006).

4. Motor

The motor shall be carefully matched to the fan load. It shall be (IP55,IP56, …etc) rated with Class F,H Insulation according to project specification . The motor bearing shall be of ball type and lubrication- free. Out of the air stream shall the motor and drive mechanism be located to avoid grease or dirt accumulation.

5. Internal wiring conduit

Fan shall be furnished with conduit to lead the power supply wiring through the curb to the motor chamber.

6. Oil Drain

The oil drain is required to discharge the oil through drainage system without accumulating it inside the fan body that will help to keep the roof clean all the time.

7. Nameplate

A permanently fixed aluminum nameplate shall clearly display the fan number, product model and serial number (a unique ID for each fan) so that the parts used can be traceable by customers.

8. Drive Mechanism (For belt drive type only)
