Helios Fans DV EC 200 Pro

The Helios DV EC 200 Pro is a roof fan designed with EC technology to deliver efficient ventilation. It features an aerodynamically optimized housing made from high-quality grey polypropylene, providing diagonal air discharge. The fan operates within a temperature range of ‑30 to +60 °C and includes integrated guide vanes to maximize efficiency. It is designed for horizontal installation.

Equipped with a mixed flow impeller constructed from aluminium, the motor-impeller unit is dynamically balanced to ensure quiet and reliable performance. The fan is powered by a DC external rotor motor with ball bearings, built for continuous operation. This electronically commutated motor maintains high efficiency even under variable control settings. It is maintenance-free and radio interference suppressed.

The fan includes integrated time and pressure control features that stabilize pressure, enabling ventilation systems to maintain optionally adjustable flow rates for consistent performance.
