HVLS（High-Volume, Low-Speed）fans are large ceiling fans designed to move large volumes of air efficiently at low rotational speeds. Below is a general outline of typical HVLS fan specifications:

1. Size

• Diameter: Typically ranges from 3.6meters (12 feet) to 7.3 meters (24 feet).
• Blade Width: Varies based on model and design.

2. Material

• Blades: High-strength aluminum or composite materials for lightweight and durability.
• Frame: Steel or aluminum, often powder-coated for corrosion resistance.

3. Motor

• Type: Direct-drive motors (gearless) or gear-driven motors.
• Power: Varies from 0.4 kW to 1.5 kW depending on the fan size and application.
• Voltage: Compatible with 220V/380V (single-phase or three-phase) systems.
• Efficiency: Typically high-efficiency, brushless motors with low energy consumption.

4. Performance

• Airflow: Capable of moving up to 500,000 CFM (Cubic Feet per Minute) or more.
• Speed: Adjustable, with maximum speeds typically between 50-120 RPM.
• Coverage Area: Effective coverage of up to1,350 square meters depending on fan size and placement.

5. Noise Level

• Quiet operation, generally below 40 dB at full speed.

6. Control System

• Features: Remote or wall-mounted control panels with variable speed settings.
• Options: Wireless Interlinked Remote Control Systems.

7. Safety Features

• Blade Reinforcements: To prevent deformation or detachment.
• Safety Cables: For secure mounting.
• Emergency Stop: Integrated in the control system.

8. Installation Requirements

• Mounting Height: Minimum recommended clearance is 3.5 meters (11.5 feet) from the floor.
• Ceiling Structure: Must be capable of supporting the fan's weight (typically 100-120 kg).

9. Certifications

• Compliance with relevant industry standards (e.g., ISO, CE, UL).
