Terrui Launches 98-Inch Industrial Exhaust Fan with Brushless EC Motor
Shanghai Terrui International Trade Co., Ltd. — a livestock equipment manufacturer founded in 2002 and dedicated to making livestock healthier and more comfortable — has introduced its 98-inch industrial exhaust fan, a high-airflow negative pressure ventilation solution engineered for large barns, greenhouses, and industrial warehouses. Powered by a brushless EC motor, the new fan moves up to 235,000 m³/h (138,000 CFM) of air while consuming up to 40% less power than conventional AC motor fans, making it a cost-effective upgrade for operations that run ventilation around the clock.
Key Features
- Brushless EC Motor: A direct-drive, outer rotor permanent magnet design with no belts, pulleys, or carbon brushes, delivering quieter operation, higher efficiency, and lower maintenance.
- Oversized 98-Inch Rotor: Six-piece alloy blades with 4 mm thickness spanning approximately 2,500 mm, enabling massive air displacement with a single unit.
- IP55 Protection: Sealed against particle ingress and water spray for dependable performance in humid, debris-heavy environments.
- Stepless Speed Control: 0–10V, PWM, and Modbus interfaces allow precise, automated climate management in response to real-time temperature changes.
Core Advantages
- Unmatched Energy Efficiency: The brushless EC motor converts more electricity into useful airflow and cuts power consumption by up to 40% compared with traditional AC fans, significantly lowering monthly operating overhead.
- Precise Climate Management: Integrated stepless speed control lets the fan respond accurately to temperature fluctuations, maintaining a stable environment that supports animal welfare and consistent production.
- Maintenance-Free Drive System: By eliminating belts, pulleys, and friction-prone carbon brushes, the direct-drive design reduces downtime and long-term maintenance labor.
- Superior Air Turnover: With 235,000 m³/h of airflow, the fan achieves rapid air exchange, effectively clearing stagnant air, heat, moisture, and odors from large facilities.

Applications
The fan is designed for negative pressure tunnel ventilation and high-volume air exchange across a wide range of facilities. It rapidly exhausts heat, moisture, and odors from modern poultry houses, dairy barns, greenhouses, and high-ceiling industrial warehouses, helping maintain a stable, comfortable climate for animals and workers alike. The oversized rotor allows a single unit to replace multiple smaller fans, reducing both installation footprint and long-term operating cost.
