Helios Heli RR100A

The Heli RR100A centrifugal tube fan is a powerful and efficient fan that has been specially designed for direct installation in pipe systems. With a diameter of 100 mm, it is ideal for conveying medium and small air volumes, even against high resistance. The housing is made of galvanised sheet steel, which ensures durability and stability. The fan is equipped with a centrifugal impeller made of plastic with backward curved blades to ensure quiet operation and high efficiency. The single-phase AC external rotor motor is maintenance-free and enables flexible speed control through voltage reduction. Thermal contacts are also integrated for additional safety. The sealed, low-noise ball bearings with long-term lubrication contribute to the longevity of the appliance and minimise maintenance requirements. Direct installation in the pipe system for optimum air flow. High-quality housing made of galvanised sheet steel. Low-noise operation thanks to special impeller design^. Maintenance-free external rotor motor with integrated thermal contacts. Speed control possible through voltage reduction.
