The Helios HRFW 450/4 is a high-performance axial fan designed with a cylindrical duct constructed from galvanized sheet steel, equipped with flanges on both ends per DIN 24155 standards. This duct encloses a highly efficient, aerodynamically optimized impeller made from durable polymers. The impeller is dynamically balanced to ensure quiet and stable operation and is suitable for ambient temperatures ranging from ‑30 °C to +60 °C.
The fan is powered by a totally enclosed AC condenser motor with integrated thermal contacts for protection. Motor speed can be adjusted via voltage reduction, allowing flexible control. The motor is maintenance-free and fitted with low-noise, sealed-for-life ball bearings. Additionally, the fan offers reversible airflow, making it versatile for various ventilation needs.
