18FT-24FT BLDC Ceiling Fan
Industrial-grade large ceiling fans with permanent magnet synchronous motors, VFD control, and airfoil blades for demanding environments.
Shanghai Aipu Fans Co., Ltd. is a China-based manufacturer and supplier of large industrial ceiling fans, specializing in 18FT-24FT BLDC ceiling fans. Since 2006, we have designed and produced high-efficiency fans for warehouses, logistics centers, industrial plants, stadiums, and exhibition halls. Our fans use permanent magnet brushless motors (PMSM) that achieve over 90% efficiency, reducing energy consumption compared to traditional AC motors. With an 8,000 square meter production base and automated machining, cutting, welding, and testing centers, we deliver reliable, cost-effective solutions for global projects.
18-foot industrial-grade adjustable speed BLDC ceiling fan
Designed for medium-large spaces, this fan offers adjustable speed control to match varying airflow demands. Ideal for workshops and assembly lines where precise air movement is needed.
Industrial-grade aviation metal large-blade BLDC ceiling fan
Built with aviation-grade metal blades for enhanced durability and performance in harsh industrial environments. Suitable for facilities with high heat or corrosive conditions.
24-foot large industrial 1.5 kW BLDC ceiling fan
Our largest model, with a 1.5 kW motor and aluminum alloy blades, delivers massive airflow for expansive spaces like distribution centers and aircraft hangars.
Application Fit
These fans are engineered for large, open areas where effective air circulation is critical. They prevent heat stratification, improve comfort, and enhance productivity.
- Warehouses and logistics centers: Reduce heat buildup and maintain a comfortable working environment for staff.
- Industrial plants and workshops: Ensure even airflow across the entire facility, mitigating heat island effects.
- Stadiums, exhibition halls, and concert venues: Provide powerful, quiet airflow to keep large audiences comfortable.

Engineering and Quality Assurance
Our fans are manufactured using high-precision automatic production lines, ensuring consistent quality and cost-effectiveness. Each unit undergoes rigorous testing in our in-house testing center. The PMSM motor features a fully enclosed structure, eliminating gear wear and noise, and requires no lubrication—reducing maintenance to virtually zero. The airfoil blades are treated with anti-corrosion and oxidation processes, then powder-coated at high temperature for a durable, easy-to-clean finish.
Configuration and Customization
We offer customization and OEM services to meet specific project requirements. Blade color, motor power, control options, and mounting accessories can be tailored to your needs. Our engineering team works with you to define the optimal configuration based on your facility's dimensions, ceiling structure, and airflow objectives.
Installation and Integration
Our fans are suitable for H-steel, concrete, ball-column, and iron structures. We provide installation guidelines and technical support to ensure safe and efficient mounting. The VFD controller includes multiple protections: phase failure, over/under voltage, overcurrent, overload, output phase loss, ground fault, and over-temperature. This ensures reliable operation even in challenging power environments.
Maintenance and Service
Thanks to the brushless motor design, maintenance is minimal. Periodic inspection of blades, fasteners, and electrical connections is recommended. We provide spare parts and after-sales support to keep your fans running for years.
Information We Use to Configure Your Solution
To prepare a precise proposal, we need the following details:
- Facility dimensions (length, width, height) and ceiling type
- Desired airflow coverage and any specific airspeed requirements
- Power supply voltage and frequency
- Environmental conditions (temperature, humidity, dust, corrosive elements)
- Number of fans and mounting layout preferences
- Any customization needs (blade color, control options, OEM branding)
Frequently Asked Questions
What is the typical lead time for 18FT-24FT BLDC ceiling fans?
Lead time depends on configuration and order quantity. Standard models typically ship within 15-30 days after order confirmation. Customized orders may require additional time for engineering and production.
Can these fans be installed in low-ceiling facilities?
Our fans require a minimum mounting height of 4 meters from the floor to the fan blades. For lower ceilings, we recommend considering our 6FT-11FT or 12FT-16FT BLDC ceiling fans, which are designed for smaller spaces.
Do you provide installation supervision or training?
Yes, we offer installation guidelines and can provide remote technical support. For large projects, we can arrange on-site supervision or training upon request.
What certifications do your fans have?
Our fans are manufactured in compliance with international standards. We hold ISO 9001 certification and our products are CE certified. Specific certifications can be provided upon request.
Can I get a sample unit for testing before bulk order?
Yes, we can supply a single unit for evaluation. The sample cost is typically deducted from the final order. Contact us to discuss sample availability and shipping.
