The HELI RRK 315 radial duct fan is a powerful ventilation fan specifically designed for direct installation in duct systems. With a housing made of impact-resistant plastic and round connection flanges that are compatible with standard ducts, this fan offers a robust and reliable solution for various ventilation applications. The high-performance radial impeller with backward-curved blades ensures an efficient airflow of up to 1060 m³/h. The fan is equipped with a maintenance-free, low-noise external rotor motor, which guarantees a long service life due to its closed design and the use of sealed ball bearings. The dynamic balancing according to quality level G 6.3 ensures vibration-free operation, further minimizing noise development. The HELI RRK 315 is therefore an ideal choice for applications where reliable and efficient air circulation is required.
