EBST EC backward curved centrifugal fans represent the convergence of advanced motor technology and precision fluid dynamics, delivering unparalleled efficiency and intelligent control capabilities for modern ventilation systems. Each EC backward curved centrifugal fan integrates a high-performance EC motor with integrated electronics, enabling sophisticated speed control through 0-10V, PWM, or RS485 communication protocols, allowing seamless integration with building automation systems and IoT platforms. The EC backward curved fan series features impellers optimized through ternary flow CFD simulation, with both composite material and aluminum alloy construction options available to match specific application requirements for weight, strength, and corrosion resistance. Every EC backward curved centrifugal fan is engineered with IP54 environmental protection rating, ensuring reliable operation even in dusty or moisture-prone environments, while F-class insulation provides thermal resilience for demanding operating conditions. Each EC backward curved fan undergoes rigorous validation including 60℃ high-temperature testing for three months and 40,000-hour lifespan testing, confirming the exceptional durability engineered into every EC backward curved centrifugal fan. The EC backward curved fan product line spans an extensive size range from 133mm to 630mm in diameter, providing solutions for applications ranging from compact IDC equipment racks to large commercial air handling systems. Maximum airflow for the EC backward curved centrifugal fan series reaches an impressive 20100m³/h with static pressure capability up to 1500Pa, delivering the performance required for demanding HVAC applications. EC backward curved fan technology proves particularly valuable in IDC data center cooling applications where precise airflow control and energy efficiency directly impact operational costs, energy storage systems requiring reliable thermal management, commercial air conditioning systems demanding variable capacity operation, and rail transit applications where durability and reliability are paramount. The EC backward curved centrifugal fan’s integrated electronics eliminate the need for external motor controllers, simplifying system design while reducing overall component count. EBST’s comprehensive engineering capabilities, backed by over 30 years of motor development experience and more than 3000 patents, ensure that every EC backward curved fan delivers the performance, efficiency, and intelligence required for the most demanding ventilation applications.
