The Helios HRFW 200/2 is a high-performance axial fan featuring a cylindrical duct made from galvanized sheet steel, equipped with flanges on both ends for easy installation. The duct dimensions and flange fixing holes conform to DIN 24155 standards. An externally mounted terminal box simplifies electrical connections.
This fan utilizes a highly efficient, 7‑blade profiled impeller constructed from impact-resistant polymers, aerodynamically optimized and dynamically balanced to Class G 6.3 in accordance with VDI 2060, ensuring smooth, vibration-free operation. The fan is suitable for use in temperatures ranging from ‑30°C to +60°C.
Equipped with a totally enclosed AC condenser motor, the fan includes built-in thermal contacts for motor protection. The motor is reversible and allows speed control through voltage reduction. Maintenance-free, low-noise sealed-for-life ball bearings guarantee quiet and reliable performance over time.
