EBST AC circular duct fans provide specialized inline ventilation solutions for applications requiring compact, efficient airflow through ducted systems. Each circular duct fan features high-strength impellers optimized through ternary flow CFD simulation technology, specifically designed to achieve optimal aerodynamic performance within the constraints of circular duct mounting configurations. The AC circular duct fan series incorporates ultra-efficient AC motors with F-class insulation, delivering reliable performance with straightforward AC power connection requiring no external controls. Every circular duct fan undergoes comprehensive validation including 65℃ high-temperature testing for three months and 40,000-hour lifespan verification, ensuring the circular duct fan delivers trouble-free operation in continuous-duty applications. The AC circular duct fan product range spans sizes from 4 inches to 12 inches, providing a comprehensive selection for residential and light commercial duct systems. Maximum airflow for the circular duct fan series reaches 1490m³/h with static pressure capability to 600Pa, delivering substantial ventilation capacity for a wide range of ducted applications. Circular duct fan applications include fresh air ventilation systems for residential and commercial buildings where energy recovery ventilation requires reliable inline fans, greenhouse ventilation systems where consistent airflow is essential for plant health, ducted ventilation for industrial facilities requiring localized exhaust, and agricultural applications where dust-resistant construction provides reliable operation. The AC circular duct fan’s compact form factor allows installation directly within ductwork, minimizing space requirements while simplifying system design. EBST’s decades of fan engineering experience ensure that every circular duct fan delivers the performance, reliability, and acoustic characteristics required for integration into complete ventilation systems.
