Commonly referred to as "Helicopter Fans" due to their massive size and blade design, High Volume, Low Speed (HVLS) fans have revolutionized climate control in large industrial and commercial spaces. By moving massive amounts of air at a low rotational speed, these fans create a natural cooling breeze that enhances worker productivity and reduces energy costs by up to 30%.
Unlike traditional gearbox-driven fans, our "Helicopter Fans" utilize Permanent Magnet Synchronous Motor (PMSM) technology. This ensures 100% maintenance-free operation, zero oil leakage, and noise levels below 45dB.
Our blades are engineered using fluid dynamics to mimic helicopter rotor efficiency, maximizing airflow while minimizing drag. This results in a "Coanda Effect" that covers areas up to 1,500 square meters.
Contributing to carbon neutrality goals, a single HVLS fan can replace dozens of small industrial fans, consuming only 1.5kW of electricity per hour.
Expertise. Professionalism. Reliability.
Established in March 2018, Suzhou Liangzhi has emerged as a high-tech powerhouse in the HVLS industry. We specialize in the R&D and manufacturing of PMSM motors and high-performance fans. With over 6 years of deep industry immersion, our core technology leads the Chinese market in motor structure, fluid dynamics, and electromagnetic thermal management.
In massive distribution centers, "Helicopter Fans" prevent moisture buildup, protecting inventory from mold while ensuring workers remain cool during high-intensity shifts.
Gyms, basketball courts, and transit hubs utilize HVLS fans to improve air quality and circulation where traditional AC is too expensive or ineffective.
Our livestock wall fans and ceiling fans are proven to reduce heat stress in dairy cows, leading to higher milk production and animal welfare.
The trend is moving towards IoT-integrated cooling. Our fans can now be connected to central building management systems (BMS) for automated speed adjustment based on real-time temperature sensors.
At Suzhou Liangzhi, we don't just assemble; we innovate. Our factory is a hub for:
We adhere to international standards to support global procurement needs.
Real-time factory tours and product detail demonstrations for remote buyers.
Full air cooling and ventilation simulation solutions tailored to your site architecture.
Custom branding and technical modifications to meet your specific market needs.
Complete peace of mind with free accessory replacement for non-human damage.
The price is primarily influenced by the motor type (PMSM vs. Induction), blade diameter (ranging from 8ft to 24ft), and safety features. PMSM fans have a higher upfront cost but significantly lower operational and maintenance costs over a 5-year period.
Unlike trading companies, we own the core PMSM technology. This allows for better quality control, direct factory pricing, and faster customization. Our 7+ years of experience ensures we understand the complexities of industrial ventilation.
Yes. Our fans are built with high-grade aluminum and corrosion-resistant coatings. The constant airflow prevents moisture stagnation, which is critical for livestock comfort and hygiene.
In winter, they destratify air (pushing warm air down), saving up to 25% on heating. In summer, the perceived temperature drops by 5-8°C, allowing you to set AC thermostats higher and saving up to 30% on electricity.
Standard models are usually ready for shipment within 7-10 days. Custom OEM orders typically take 15-25 days depending on the volume and technical requirements.
