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.

Versatile for Various Large Spaces with Proven Practicality

Our big industrial fans excel in diverse large spaces: they improved air circulation and productivity at Hangzhou Kelda Welding’s workshop, upgraded BYD’s warehousing experience, and work for gyms, barns too. They quickly extract dirty air for environmental dust removal, enhancing space comfort and operational efficiency.

Safety is the non-negotiable paramount concern in any industrial setting. A big industrial fan with comprehensive safety certification is engineered, tested, and verified to operate with utmost reliability, mitigating risks to personnel, infrastructure, and processes. These certifications, such as CE, ISO, and other international standards, provide independent validation that the fan's design and construction adhere to rigorous safety protocols. Key safety features include a securely guarded fan blade assembly designed to contain any component in the unlikely event of a structural failure. The mounting system, whether ceiling, wall, or pole-based, is over-engineered with high-grade materials and redundant safety cables to ensure absolute structural integrity and prevent any possibility of detachment. The electrical systems are housed in sealed, waterproof enclosures rated for industrial environments, protecting against dust, moisture, and short circuits. Furthermore, motors are equipped with thermal overload protection to prevent overheating and potential fire hazards. In environments like food processing plants or chemical storage facilities where hygiene and corrosion resistance are critical, safety-certified fans are constructed from certified materials that meet industry-specific hygiene standards (e.g., FDA-compliant coatings) and are designed for easy cleaning to prevent bacterial growth. The certification process also ensures that electromagnetic compatibility (EMC) standards are met, preventing the fan from interfering with other sensitive electronic equipment. Choosing a certified fan is not merely a best practice; it is often a mandatory requirement for insurance compliance and meeting occupational health and safety regulations. It provides peace of mind that the equipment contributing to comfort and efficiency will not become a liability. We provide fans with a full suite of international safety certifications. Contact us for a detailed list of certifications applicable to your region and industry.

User evaluation of the product

Lisa Thompson

We installed Dawangfan's big industrial fans in our 5,000㎡ warehouse 6 months ago. Built on PMSM theory, they’re surprisingly energy-efficient—our monthly electricity cost for ventilation dropped by 35%. The airflow covers every corner, solving the stuffy issue in summer. Super reliable so far.

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.
