The Helios HRFW 250/2 is a high-performance axial fan designed with a galvanized sheet steel cylindrical duct equipped with flanges on both ends, facilitating easy installation. The duct and flange fixing holes conform to DIN 24155 standards. A terminal box is mounted externally on the casing for convenient wiring access.
This fan includes a highly efficient profiled blade impeller made from durable polymers, optimized aerodynamically for its application and dynamically balanced to ensure smooth operation. It is suitable for ambient temperatures from ‑30 °C to +60 °C.
Powered by a totally enclosed AC condenser motor with integrated thermal contacts, the HRFW 250/2 offers reversible operation and speed control via voltage reduction. Maintenance-free, low-noise sealed-for-life ball bearings ensure quiet and reliable performance.
