Product Description

Product Description

EC Series: High-Efficiency Unhoused Plenum Fan

    The EC Plenum Fan represents the pinnacle of modern air movement technology. Unlike traditional centrifugal fans, it discharges air directly into the surrounding plenum, converting dynamic pressure into static pressure within the chamber. The integrated EC motor features onboard power electronics, enabling precise, stepless speed control and significantly lower energy consumption compared to conventional AC-driven systems.

Core Product Features
    Integrated EC Motor Technology: Features a permanent-magnet brushless motor with integrated drive electronics, offering up to 90% efficiency and simplified wiring.
    Space-Saving Unhoused Design: The absence of a volute casing allows for multi-fan "fan wall" configurations and reduces the overall footprint of HVAC equipment.
    Precision Backward-Curved Impeller: Fabricated from high-strength composite materials or aluminum alloy, the impeller is aerodynamically optimized for high-pressure performance and low noise.
    Stepless Speed Regulation: Supports 0-10V / PWM control signals or Modbus RTU communication for real-time monitoring and demand-based airflow adjustment.
    Plug-and-Play Installation: The compact "Plug Fan" structure is pre-assembled on a rigid mounting frame, ensuring fast installation and easy maintenance access.
    Acoustically Optimized: The combination of an unhoused discharge and an EC motor results in a lower low-frequency noise spectrum, ideal for noise-sensitive commercial environments.
