    Product Overview
    ⚙️
    1. The GDF series of centrifugal duct fans feature either forward-curved or backward-curved multi-blade centrifugal impellers, with single-sided air intake. The fans are designed for horizontal air intake and exhaust, and the square air inlets and outlets can be directly connected to the air ducts. The fan motors are specifically designed for air conditioning systems, and the entire unit is characterized by low noise, smooth operation, and long service life.
    📏
    2. The fans are available in nineteen different sizes based on the diameter, ranging from 180mm to 560mm. The series offers air volumes from 160 to 9100 cubic meters per hour and total pressures from 73 to 570 Pascals.
    🛡️
    3. To meet the noise requirements of different environments, the fans are available in two types:
    Standard type: All components are made of galvanized steel sheets formed by seaming or riveting.
    Silencing type: The fan part is made of galvanized steel sheets formed by seaming or riveting, and the casing is lined with sound-absorbing cotton.
