EBST AC backward curved centrifugal fans deliver robust, reliable performance for industrial and commercial ventilation applications where consistent airflow and durability are paramount. Each AC backward curved centrifugal fan is engineered with precision using ternary flow CFD simulation technology, optimizing the impeller design for maximum efficiency across the entire operating envelope. The AC backward curved fan series features impellers constructed from either advanced composite materials or high-strength aluminum alloy, selected based on specific application requirements to provide optimal balance of weight, strength, and aerodynamic performance. Every AC backward curved centrifugal fan incorporates an ultra-efficient AC motor with F-class insulation, capable of withstanding demanding operating conditions including 65℃ ambient temperatures for extended periods. Each AC backward curved centrifugal fan undergoes comprehensive validation including 40,000-hour life testing, ensuring the AC backward curved fan delivers trouble-free operation even in continuous-duty applications such as air handling units and fan filter units. The AC backward curved fan product line spans a comprehensive size range from 133mm to 560mm in diameter, accommodating diverse installation requirements from compact IDC small cabinets to large-scale commercial air conditioning systems. With maximum airflow capacity reaching 12315m³/h and static pressure up to 800Pa, this AC backward curved centrifugal fan series provides exceptional flexibility for engineers specifying ventilation solutions. Applications for the AC backward curved fan extend across air handling units, fan filter units for cleanroom environments, IDC server cabinets, high-voltage inverter cabinets requiring reliable cooling, energy storage charging stations, and rail transit systems where dependable operation is non-negotiable. EBST’s decades of manufacturing experience, combined with over 3000 patents in motor and fan technology, ensure that every AC backward curved centrifugal fan delivers the performance, efficiency, and longevity required for mission-critical ventilation applications worldwide.
