26FT-28FT HVLS Fans: Maximum Coverage for Large-Scale Facilities
Shanghai Aipu Fans Co., Ltd. is a China-based manufacturer and supplier of industrial-grade HVLS fans. Our 26FT-28FT HVLS Fans represent the largest diameter in our product range, engineered for facilities where air movement over vast areas is critical. These fans are the go-to solution for warehouses, aircraft hangars, gymnasiums, arenas, and agricultural buildings, delivering high-volume airflow at low rotational speeds to maximize energy efficiency.
As a factory with an 8,000-square-meter production base, we combine automated manufacturing with rigorous testing to ensure each fan meets the demands of continuous industrial operation. Our 26-28 foot models are built to reduce heat stratification, control humidity, and improve air quality, directly impacting operational costs and worker comfort.
Why Choose Our 26FT-28FT HVLS Fans?
- Energy Efficiency: Large diameter and low speed move more air with less energy compared to multiple small fans or air conditioning systems.
- Robust Construction: Airfoil blades made from a specialized aluminum alloy with reinforcing ribs prevent sagging and fatigue.
- Advanced Motor Technology: Germany Nord motors with IP55 protection and IE2 efficiency, ensuring reliable performance and longevity.
- Smart Control: Imported Danfoss inverters provide variable speed control, overload protection, and reversible airflow for seasonal use.
- Certified Quality: Our fans are CE, UL, and CCC certified, meeting international safety and performance standards.
Product Range: 26-Foot and 28-Foot Models
Our 26FT-28FT HVLS Fans category includes two primary models, each tailored to specific facility requirements. Both models share the same core engineering principles but differ in diameter to match coverage needs.
Application Fit: Where 26-28 Foot Fans Excel
These fans are designed for spaces with high ceilings (4.5 to 18 meters) and large floor areas. They are particularly effective in:
- Warehouses and Logistics Centers: Reduce heat buildup, control humidity, and eliminate odors, maintaining consistent temperatures for stored goods.
- Manufacturing Plants: Counteract heat from machinery and production processes, improving air quality and worker safety.
- Aircraft Hangars and Large Assembly Halls: Provide uniform airflow across expansive areas where traditional fans are impractical.
- Sports Facilities and Arenas: Enhance spectator and athlete comfort without the noise of high-speed fans.
- Agricultural Buildings: Improve ventilation in barns and livestock facilities, promoting animal health.
Engineering and Quality Assurance
Our manufacturing process integrates machining, cutting, welding, and testing centers, all equipped with high-precision automatic machines. This ensures consistent quality and cost-effectiveness. Each fan undergoes strict inspection to verify performance and safety.
Key engineering features include:
- Motor: Germany Nord motor with IP55 protection, IE2 efficiency, and a trapezoidal shaft structure for enhanced safety.
- Inverter: Danfoss inverter with IP55 protection, overload and over-current protection, and built-in RF interference filter.
- Blades: Streamline airfoil design, one-time molded from aluminum alloy with reinforcing ribs to prevent sagging.
- Reversible Operation: Fans can run clockwise or counterclockwise for summer cooling and winter destratification.
Installation and Integration
Proper installation is critical for optimal performance. We provide detailed installation guidelines and support to ensure your fan is mounted safely and effectively.
Installation Requirements:
- Building height: 4.5 to 18 meters.
- Fan mounting point must be at least 4 meters above the floor.
- Secure mounting to a safe bearing girder; structural modification may be needed.
- Maintain a safe distance from obstacles such as lighting or other equipment.
- Avoid installation in areas with excessive heat, oil pollution, or flammable/explosive materials.
Our team can assist with site assessment and provide recommendations for mounting hardware and electrical connections. We support both new installations and retrofits.
Controls and Automation
Each fan comes with a Danfoss inverter that allows precise speed control. The inverter can be integrated with building management systems (BMS) for automated operation based on temperature or time schedules. This enables energy savings by adjusting airflow to demand.
We offer optional remote control and smart sensors for enhanced automation. Our technical team can help configure the control system to match your facility's existing infrastructure.
Customization and OEM Services
We understand that every facility is unique. As a manufacturer, we offer customization options including:
- Blade color and finish to match your branding or environment.
- Voltage and frequency variations (380V-420V / 220V-240V) to suit regional power supplies.
- Control options (wall-mounted, remote, or BMS integration).
- OEM manufacturing with your branding and specifications.
Our engineering team works closely with you to ensure the final product meets your exact requirements.
Maintenance and Support
To ensure long service life, we recommend regular maintenance including:
- Periodic inspection of blade bolts and torque.
- Cleaning of blades to maintain balance and airflow.
- Lubrication of motor bearings as per manual.
- Checking inverter parameters and error logs.
We provide comprehensive documentation, including installation manuals, operation guides, and maintenance schedules. Our after-sales team is available to answer questions and provide spare parts.

Frequently Asked Questions
What is the maximum mounting height for your 26-28 foot fans?
Our fans are suitable for buildings with heights from 4.5 meters up to 18 meters. The fan should be mounted at least 4 meters above the floor to ensure safe clearance.
Can these fans be used in outdoor or semi-outdoor environments?
Our standard fans are designed for indoor use. For outdoor or corrosive environments, we recommend discussing with our engineers to explore protective coatings or materials.
How many fans do I need for a 10,000 square meter warehouse?
The number depends on ceiling height, layout, and desired airflow. As a rule of thumb, a 26-28 foot fan covers approximately 1,500-2,000 square meters. We can perform a free layout assessment based on your building details.
What is the energy consumption of a 28-foot fan?
While exact figures depend on speed settings, our 28-foot fans typically consume around 1.5 kW at full speed, significantly less than multiple small fans or air conditioning units covering the same area.
Do you offer installation services?
We provide detailed installation instructions and can recommend certified installers in your region. For large projects, our team can offer on-site supervision or training.
What is the lead time for custom orders?
Lead time varies based on configuration and order volume. Standard models are usually in stock, while custom orders may take 2-4 weeks. We confirm exact lead times with each quotation.
