EBST DC backward curved centrifugal fans represent the ideal solution for applications requiring precise airflow modulation combined with exceptional energy efficiency. Each DC backward curved centrifugal fan integrates an ultra-efficient DC motor with advanced electronic control capabilities, enabling seamless speed adjustment through 0-10V or PWM signals to perfectly match varying ventilation demands. The DC backward curved fan series features impellers optimized using ternary flow CFD simulation technology, ensuring that every DC backward curved centrifugal fan achieves optimal aerodynamic performance while minimizing noise generation. Composite material impellers provide lightweight durability, while aluminum alloy options deliver enhanced structural integrity for demanding applications. Every DC backward curved centrifugal fan incorporates F-class insulation motors that have successfully completed 60℃ high-temperature testing over three months and 40,000-hour lifespan validation, demonstrating the exceptional reliability engineered into each DC backward curved fan. The DC backward curved fan product range spans diameters from 113mm to 355mm, offering compact form factors ideal for space-constrained installations without compromising performance. Maximum airflow for the DC backward curved centrifugal fan series reaches 2960m³/h with static pressure capability up to 800Pa, providing substantial ventilation capacity for a wide spectrum of applications. These DC backward curved fan units excel in air handling units requiring variable air volume control, fan filter units for cleanroom environments, IDC data center cabinets demanding precise thermal management, energy storage systems where efficiency directly impacts battery life, and rail transit applications where reliability under vibration is essential. The DC backward curved centrifugal fan’s ability to maintain consistent performance across its speed range makes it particularly valuable for applications with fluctuating cooling requirements. EBST’s vertically integrated manufacturing, combining motor development, fluid design, and electronic control expertise under one roof, ensures that every DC backward curved fan delivers the precise performance characteristics required for modern ventilation systems.
