We Offer PMSM-based Big Industrial Fans – Safe, Energy-Saving for Large Spaces

As a professional manufacturer, we specialize in big industrial fans, mainly HVLS (High Volume Low Speed) types developed based on PMSM (Permanent Magnet Synchronous Motor) theory. Our big industrial fans boast outstanding energy efficiency and superior performance. Safety is our priority: unique blade design, patented hub, and buffer structure ensure no falling or blade separation even in emergencies. They excel in environmental dust removal by quickly extracting dirty air. Ideal for workshops (e.g., Hangzhou Kelda Welding factory), warehouses (e.g., BYD warehouses), gyms, and barns, they improve air circulation, control temperature, enhance comfort, and boost productivity. We also provide comprehensive 4S maintenance, making them reliable for large spaces.

Why choose us?

Cutting-edge PMSM Technology for Superior Performance & Energy Savings

We develop our big industrial fans based on PMSM (Permanent Magnet Synchronous Motor) theory and aerodynamic principles. This advanced tech ensures outstanding energy efficiency—slashing electricity costs for your space—while delivering powerful airflow, solving hot and stuffy issues in large areas like workshops and warehouses.

Unmatched Safety Guaranteed by Patents & Innovative Design

Our big industrial fans feature unique blade design, patented hub, and buffer structure. They won’t separate or fall even in emergencies; patented connections prevent falling unless the building collapses. With 45+ patents, we prioritize your safety in every scenario.

Professional 4S Maintenance & Trusted by Global Leaders

Beyond quality fans, we offer comprehensive 4S maintenance (sales, spare parts, service, surveys). With 5000+ customers including SAIC, Haier, and China Post, our reliable products and high-standard services make us a trusted partner for your large-space ventilation needs.

The integration of Artificial Intelligence (AI) marks the transition from manual fan operation to a fully automated, intelligent environmental management system. An AI-controlled big industrial fan goes beyond simple timers or thermostats; it uses a network of sensors and machine learning algorithms to optimize fan operation in real-time for maximum comfort and efficiency. The system continuously collects data on parameters such as ambient temperature, humidity, occupancy levels (via CO2 sensors or infrared), and even external weather conditions. The AI software analyzes this vast dataset, learns the thermal dynamics of the building, and automatically adjusts the speed, direction, and operation of each fan in the network to maintain pre-set environmental conditions. For example, on a sunny afternoon, the system might increase fan speed in the area where the sun is heating the roof. If a section of a warehouse becomes occupied by workers, the AI can direct increased airflow to that specific zone. It can also predictively adjust settings based on learned patterns, such as increasing ventilation before a scheduled shift starts. This results in unprecedented energy savings, as the system uses the absolute minimum energy required to achieve the desired comfort level, avoiding wasteful operation. It also provides a hands-off approach for facility managers, ensuring optimal conditions are maintained 24/7 without manual intervention. The AI platform often offers remote monitoring and control via a web dashboard or smartphone app, providing valuable insights into energy usage and environmental trends. This represents the future of industrial climate control, transforming fans from simple appliances into a responsive, data-driven ecosystem. To learn more about our AI automation solutions and how they can be integrated into your new or existing ventilation system, please contact our smart technology division for a consultation.

User evaluation of the product

Daniel Wilson

As a workshop manager, I value after-sales service most. Dawangfan’s big industrial fans work great for our welding workshop—dust is removed faster. Their 4S maintenance team did quarterly checks proactively, replaced a small spare part quickly when needed. Totally trustworthy.

Karen Davis

Our gym is tall and expansive, and air stagnation was a big issue. Dawangfan’s big industrial fans changed that—members no longer complain about stuffiness during workouts. They’re quiet and energy-saving, and the team even did a pre-installation survey to find the best positions. Great product!
