The Terrui Max Airflow Series represents the next generation of industrial-grade livestock ventilation fan technology, engineered for superior performance and unmatched energy efficiency. Powered by an advanced outer rotor permanent magnet brushless motor (PMSM/BLDC), this fan delivers a staggering 66,000 m³/h (38,800 CFM) of air volume. As a high-efficiency livestock ventilation fan, it is specifically designed to provide precise climate control, effectively mitigating heat stress and drastically improving air quality in modern dairy barns, poultry houses, and large-scale industrial facilities.

• Ultra-High Energy Efficiency: By utilizing permanent magnet brushless technology, this livestock ventilation fan consumes 30% to 50% less electricity than traditional asynchronous motor fans, significantly reducing long-term operational overhead.
• Precision Stepless Speed Control: The integrated smart drive allows for smooth, stepless speed adjustments, enabling the livestock ventilation fan to be fine-tuned to the exact cooling requirements of the animals at any time of day or night.
• Maintenance-Free Direct-Drive: The outer rotor direct-drive architecture eliminates the need for belts, pulleys, and tensioners—removing the most frequent failure points found in standard barn ventilation systems.
• Optimal Air Exchange: Delivering up to 66,000 m³/h, this livestock ventilation fan ensures rapid air turnover, effectively clearing ammonia, moisture, and CO2 to maintain a healthy herd environment.

• Industry-Leading 66,000 m³/h Airflow: Optimized blade geometry combined with high-torque motor synchronization creates a powerful air column for rapid heat dissipation across large areas.
• Outer Rotor PMSM Motor: Unlike internal rotor motors, the outer rotor design provides superior torque and better heat dissipation, ensuring the fan remains cool and efficient during continuous 24/7 operation.
• Corrosion-Resistant Industrial Build: Every component is treated to withstand the high ammonia levels and humidity typical of intensive livestock farming "trenches."
• Acoustically Balanced Operation: Precision balancing of the motor and blades ensures high-volume performance with minimal noise, reducing animal stress and agitation.

Terrui is a global leader in "Smart Ventilation" infrastructure. Our livestock ventilation fan solutions are developed using advanced computational fluid dynamics and lab-tested for the harshest real-world barn conditions. We understand that effective ventilation is the fundamental difference between a high-performing herd and health-related production losses. By choosing our PMSM/BLDC series, you are investing in the most reliable, energy-saving, and long-lasting ventilation technology available on the market today.

Q: How does the brushless motor improve the fan's lifespan?

A: Since there are no carbon brushes to wear down and no belts to snap, mechanical friction and internal heat are significantly reduced. This extends the life of the motor bearings and electronic components, ensuring years of trouble-free operation.

Q: Is this livestock ventilation fan easy to install in existing facilities?

A: Yes. Its direct-drive design and integrated controller simplify the wiring process and mounting requirements, making it an ideal choice for both new barn constructions and retrofitting older ventilation systems.

Q: Can it be connected to a centralized barn management system?

A: Absolutely. Our fans are designed for "Smart Farming" and support standard control signals, allowing them to integrate seamlessly with your existing climate control and monitoring software.
