Product Documentation

An HVLS (High Volume Low Speed) fan is a large-diameter ceiling fan designed to move a massive volume of air at a slow rotational speed. Instead of creating a small high-speed airflow like traditional fans, HVLS fans generate a gentle, broad airflow that circulates air efficiently across large spaces.

HVLS fans improve comfort, reduce energy costs, enhance ventilation, eliminate hot spots, and increase worker productivity. They also support HVAC systems by improving air mixing and destratification.

Depending on size and building conditions, a single HVLS fan can cover up to 1,500–2,000 m² (16,000–22,000 sq ft).

Traditional fans rely on high speed to move air, causing noise and turbulence. HVLS fans use large blades and low speed to create smooth, energy-efficient airflow that covers wider areas with minimal noise.

Yes. HVLS fans help regulate temperature by enhancing air circulation, reducing trapped heat, and improving overall comfort even in hot manufacturing environments.

Depending on model and size, an HVLS fan typically consumes 0.3 kW to 1.5 kW, making it significantly more energy-efficient than multiple small industrial fans.

Absolutely. HVLS fans distribute conditioned air evenly, allowing HVAC systems to run at lower settings. This can reduce energy costs by 20–30%.

Absolutely. HVLS fans distribute conditioned air evenly, allowing HVAC systems to run at lower settings. This can reduce energy costs by 20–30%.

The minimum recommended installation height is 6 meters (20 feet) for optimal airflow and safety.

No. HVLS fans operate at low speeds and use aerodynamic blades, producing extremely low noise levels—ideal for factories, warehouses, gyms, and commercial areas.

They reduce heat stress, circulate fresh air, eliminate stagnant air zones, and create a natural cooling sensation of 5–8°C, directly improving worker performance and safety.

Yes. The continuous airflow helps reduce humidity, prevent condensation, and improve air quality by removing stagnant and polluted air pockets.

Most HVLS fans support variable speed control (0–100%), allowing precise adjustment for different temperature and airflow needs.

Yes. Modern HVLS systems support group control, central controllers, touch panels, and smart automation.

HVLS fans require minimal maintenance. Routine tasks include checking bolts, verifying safety cables, cleaning blades, and inspecting motor performance every 6–12 months.

Common safety features include:

• Dual safety cables
• Blade retention systems
• Hub strengthening design
• Overspeed protection
• Auto-stop in abnormal voltage or conditions

Yes. HVLS fans are designed for industrial settings and can operate reliably even in dusty, humid, or high-temperature areas.

Yes. HVLS fans comply with NFPA fire codes. When installed with proper clearance, they do not obstruct fire sprinkler patterns.

A clearance of 1–1.5 meters (3–5 feet) between the fan hub and ceiling ensures optimal airflow.

Yes, provided they are protected from direct rain. Many HVLS fans support semi-outdoor and covered outdoor installations.
