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 factory workshop is a complex environment where ventilation and cooling directly impact safety, productivity, and product quality. A big industrial fan tailored for this setting addresses multiple concurrent challenges. Firstly, it mitigates heat generated by industrial processes, machinery, and human labor, significantly improving worker comfort and reducing the risk of heat stress. This leads to higher concentration levels, fewer errors, and increased productivity. Secondly, the constant air movement is crucial for maintaining air quality by dispersing fumes, dust, and mist generated from welding, cutting, grinding, or painting operations, thus protecting employee health and meeting occupational safety standards. Thirdly, the destratification effect ensures a uniform temperature throughout the workshop, which is vital for certain manufacturing processes that are sensitive to thermal fluctuation and for protecting precision machinery from overheating. In a metal fabrication shop, for instance, these fans would cool workers at their stations, help exhaust welding smoke, and prevent heat buildup around CNC machines. The robust design of these fans ensures they can withstand the typical workshop environment, which may include airborne particulates, vibration, and higher humidity. The energy savings achieved by reducing the need for spot cooling and exhausting conditioned air are also a significant financial benefit for any manufacturing operation. Selecting the right fan involves considering ceiling height, heat sources, and airflow paths. We provide expert analysis to design the most effective cooling and ventilation solution for your specific workshop layout and processes.

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.

David Kim

We chose their big industrial fans for our dairy barn. Safety is key here, and their patented design gives us peace of mind—no blade separation risks. They improve air circulation, reducing humidity and keeping cows healthier. Performance is way better than our old fans.
