The Helios HRFW 315/6 is a high-efficiency axial fan featuring a cylindrical duct made of galvanized sheet steel, with flanges on both ends for easy mounting. The flange dimensions and fixing holes comply with DIN 24155 standards. A terminal box is mounted on the outer casing for convenient electrical connections.
Equipped with a profiled impeller featuring 7 blades manufactured from impact-resistant polymers, the fan is dynamically balanced to Class G 6.3 according to VDI 2060, ensuring smooth and quiet operation. It is designed for use in temperatures ranging from ‑30°C to +60°C.
The fan is driven by a totally enclosed AC condenser motor with built-in thermal contacts. The motor speed can be controlled via voltage reduction. Maintenance requirements are minimal thanks to low-noise, sealed-for-life ball bearings. Additionally, the fan is reversible, offering flexible airflow control.
