    Product Details

    Product Overview

    1. The JYF silent fan duct booster fan is a box-type centrifugal fan using a forward-inclined multi-blade impeller and a low-noise external rotor motor. The motor is directly connected to the impeller, eliminating belt drive losses and improving efficiency and stability. The unit consists of a high-precision impeller, energy-efficient motor, and a sound-absorbing housing, significantly reducing vibration and noise compared with traditional belt-driven fan boxes, while maintaining strong and stable airflow output.

    2. The unit adopts a compact integrated structure with a small installation footprint, making it suitable for ceiling or narrow-space installation. Despite its compact size, it delivers large air volume, stable pressure, and efficient airflow distribution. The aerodynamic optimized flow channel reduces resistance and energy loss, while the sound-insulated casing further enhances noise reduction performance, ensuring quiet operation under high-load conditions.

    JYF Silent Fan Duct Booster Fan Overview
    Product Application

    The silent ducted fan is widely used in HVAC ventilation and air conditioning systems for offices, hotels, museums, stadiums, schools, libraries, hospitals, exhibition halls, and other public or commercial buildings.

    It is especially suitable for low-noise environments such as conference rooms, classrooms, laboratories, and high-end residential spaces. It supports fresh air supply, exhaust ventilation, and air circulation in centralized HVAC systems. With advantages of low noise, high efficiency, stable performance, and easy installation, it is an ideal solution for modern building ventilation and air quality control systems.
