The HELI RR100A radial duct fan is a powerful and efficient fan specifically designed for direct installation in duct systems. With a diameter of 100 mm, it is ideal for moving medium and small volumes of air, even against high resistance. The housing is made of galvanized steel sheet, ensuring durability and stability. The fan is equipped with a radial impeller made of backward-curved plastic blades to guarantee quiet operation and high efficiency. The single-phase external rotor motor is maintenance-free and allows for flexible speed control through voltage reduction. Additionally, integrated thermal contacts provide extra safety. The sealed, low-noise ball bearings with long-term lubrication contribute to the longevity of the device and minimize maintenance efforts.
