The Helios DV EC 250 Pro is a roof fan featuring advanced EC technology for efficient ventilation performance. It has an aerodynamically designed housing made from high-quality grey polypropylene with diagonal air discharge, suitable for horizontal installation. The fan operates effectively in temperatures ranging from ‑30 to +60 °C and includes integrated guide vanes to optimize airflow.
The unit is equipped with a mixed flow impeller made of aluminium, with the motor-impeller assembly dynamically balanced to reduce noise and vibration. The fan is powered by a DC external rotor motor with ball bearings, engineered for continuous use and electronically commutated to maintain high efficiency, even when operating under variable speed control. The motor is maintenance-free and designed to suppress radio interference.
This model includes built-in time and pressure controls that help stabilize pressure, enabling ventilation systems to maintain adjustable flow rates as needed for consistent and reliable air movement.
