Helios Fans HRFD 500÷2÷2

The Helios HRFD 500÷2÷2 is a robust low-pressure axial fan engineered for efficient airflow in ducted ventilation systems. Housed in a galvanized steel cylindrical casing with standardized DIN 24155 flanges at both ends, this fan offers straightforward integration into existing ductwork. The terminal box is conveniently mounted on the exterior for simplified wiring access.

Its aerodynamically optimized impeller, crafted from high-strength polymers, features a dynamically balanced blade design to ensure stable, low-vibration performance. Designed to operate reliably in temperature ranges from ‑30 °C to +60 °C, the HRFD 500÷2÷2 is well-suited for demanding industrial and commercial environments.

This model is equipped with a totally enclosed 3‑phase squirrel cage motor, complete with thermal overload protection for safe, continuous operation. The motor is controllable via voltage reduction and built for long service life, with maintenance-free, sealed-for-life ball bearings that minimize operational noise. The HRFD 500÷2÷2 delivers dependable, high-volume ventilation with low energy consumption.
