HVLS (High-Volume, Low-Speed) fans are large-diameter industrial fans designed to move massive volumes of air at low rotational speeds. Typically ranging from 2.1 meters to 7.3 meters in diameter, these fans operate on the principle of air stratification, creating a gentle, consistent airflow that covers extensive areas. Widely recognized for their energy efficiency and performance stability, HVLS fans have become essential equipment in industrial and commercial ventilation, temperature regulation, and air circulation scenarios. Aipu, as a trusted manufacturer, integrates advanced motor technology and safety engineering into its HVLS fan lineup, delivering reliable solutions for diverse environmental needs.
The production of Aipu HVLS fans adheres to strict international standards and undergoes a rigorous, precision-oriented manufacturing process:

HVLS fans are versatile across multiple industries, with core application scenarios including:
• Industrial Facilities: Factories, workshops, warehouses, and logistics centers. They effectively reduce ambient temperatures, improve air quality, and enhance employee comfort while preventing moisture buildup and protecting stored goods.
• Commercial Spaces: Supermarkets, exhibition halls, gymnasiums, and large shopping malls. The large-area airflow replaces cumbersome small fans, creating a comfortable and quiet environment for customers and visitors.
• Agricultural Settings: Livestock farms (poultry, pig, and dairy farms) and greenhouses. They promote air circulation to reduce disease incidence in livestock, regulate humidity for crop growth, and mitigate heat stress.
• Logistics & Warehousing: Cold storage facilities and cargo yards. They help maintain uniform temperatures, prevent frost accumulation, and ensure the quality of perishable goods and industrial materials.

Big Fans, Low Speed, Real Results: HVLS Industrial Fans Explained When a factory floor hits 34°C, small fans only move hot air around. Large-diameter HVLS ceiling fans do the opposite: they push a thick column of air downward and create an even air blanket across the whole facility — with fewer ma...

READ MOREShanghai Aipu Fans Co., Ltd. is a China-based HVLS Fans manufacturer and supplier, specializing in large-diameter ceiling fans from 7 to 28 feet. Since 2006, we have engineered industrial-grade fans that move massive volumes of air at low rotational speeds, providing energy-efficient ventilation and cooling for factories, warehouses, logistics centers, agricultural facilities, and commercial venues. Our HVLS fans are designed to eliminate air stratification, improve comfort, and reduce energy costs—backed by our 8,000 m² production base and advanced manufacturing capabilities.
Our product range covers four size categories to match different building heights and coverage requirements. Each fan is built with precision motor technology, aerodynamic blades, and robust safety features, ensuring reliable performance in demanding environments. We support customization and OEM services to meet specific project needs.
We offer a complete line of HVLS fans, each tailored to specific space dimensions and airflow demands. Below is a breakdown of our categories and their typical applications.
| Category | Diameter Range | Ideal Applications | Key Features |

HVLS fans are not one-size-fits-all. Our selection process considers your building height, floor area, and airflow requirements. For instance, a 7-foot fan suits a small workshop with a ceiling height of 4.5-6 meters, while a 24-foot fan is designed for high-bay warehouses where air stratification is severe. Our fans create a downward air column that spreads horizontally, ensuring uniform temperature and comfort across the entire space.
We integrate advanced motor technology, such as the Germany “Nord” motor and PMSM motors, to deliver high efficiency and low noise. Our blades are made from aerospace-grade aluminum alloy with an airfoil profile, optimizing airflow while minimizing drag. This engineering approach reduces energy consumption by up to 50% compared to traditional cooling methods, and when paired with air conditioning, it can cut runtime significantly.
Each HVLS fan is rated for specific airflow (CFM), power consumption, and noise levels. Our fans operate at low speeds (typically 30-120 RPM) to move large volumes of air quietly. For example, a 24-foot fan can cover up to 20,000 square feet, while a 7-foot fan covers about 2,000 square feet. We provide detailed performance data in our proposals, including airflow, static pressure, and energy consumption, based on your site conditions.
Our motors are IP55 rated, ensuring protection against dust and water jets, and meet IE2 efficiency standards. We offer both clockwise and counterclockwise rotation for summer cooling and winter destratification. Control systems include VFD controllers with overload, over-voltage, and phase-loss protection, ensuring safe and reliable operation.
We understand that every facility is unique. Our HVLS fans can be configured with various mounting options, blade colors, and control systems. For automation, we offer integration with building management systems (BMS) via Modbus or analog signals, allowing remote monitoring and speed adjustment. Our VFD controllers support multiple protection features and can be programmed for automatic start/stop based on temperature or time schedules.
We also provide customization services, including blade length, motor power, and voltage (220V-240V or 380V-420V). For OEM projects, we can adapt our fans to meet specific branding or performance requirements.
Proper installation is critical for performance and safety. Our fans are suitable for buildings with heights from 4.5 to 18 meters, and we provide detailed installation guidelines. The fan must be mounted at least 4 meters above the floor, on a safe bearing girder, with no obstacles within the fan's sweep area. We recommend avoiding areas with excessive heat, oil pollution, or flammable materials.
Safety is paramount. Our fans feature multiple safety mechanisms, including safety cables, reinforced blades, and emergency stop functions. The motor and inverter have built-in protection against overload, over-current, and short circuits. Regular maintenance is minimal due to low-speed operation and sealed bearings, but we recommend annual inspections to ensure optimal performance.
Our production process adheres to strict international standards. We use high-precision automatic machines in our machining, cutting, welding, and testing centers. Each fan undergoes rigorous testing, including motor performance, blade balance, and safety checks. We hold certifications such as CCC, CE, and UL for our motors and electrical components, ensuring compliance with global standards.
Before shipment, we conduct a full functional test to verify airflow, noise, and vibration levels. We also provide test reports and documentation for your records. For large projects, we can arrange factory acceptance testing (FAT) to demonstrate compliance with your specifications.
We supply comprehensive documentation with every order, including installation manuals, operation guides, and maintenance schedules. Our team provides on-site training for your maintenance staff, covering fan operation, troubleshooting, and safety procedures. We also offer after-sales support via phone, email, or on-site visits, ensuring your fans operate efficiently throughout their lifespan.
Spare parts are readily available, and we maintain a stock of common components such as blades, motors, and controllers. Our global shipping network ensures timely delivery, and we can package fans for safe transport, whether in crates or containers.
To prepare an accurate proposal, we need the following details from you:
With this information, we can recommend the optimal fan size, quantity, and configuration to meet your airflow and energy efficiency goals.
Our HVLS fans are designed for long-term industrial use, with a lifespan of 10-15 years under normal operating conditions. The low-speed operation reduces mechanical stress, and the sealed bearings require minimal maintenance.
Yes, our fans can run in reverse to gently push warm air trapped near the ceiling down to the floor, reducing heat stratification and improving heating efficiency. This can lower heating costs by up to 20%.
