Helios Fans VDW EC 200

The Helios VDW EC 200 is a vertical discharge EC roof fan designed for high efficiency and reliable operation. Its housing is made from seawater-resistant aluminium with an integrated protection guard to ensure durability and safety in outdoor conditions. The motor support and base plate are constructed from galvanised steel and include an inlet cone to optimise airflow. Threaded bolts on the base plate allow easy mounting of intake air accessories in accordance with DIN 24155 (page 3). A bird guard fitted at the outlet complies with DIN EN ISO 13857 safety standards.

This fan features a high-efficiency backward curved centrifugal impeller made from galvanised sheet steel, dynamically balanced to DIN ISO 1940 – 1 for smooth and consistent airflow.

Powered by an energy-saving, speed-controllable EC external rotor motor with maximum efficiency, the fan is maintenance-free and interference-free. The motor is ball bearing mounted and includes integrated electronic temperature monitoring for both the motor and control electronics. An internal potentiometer is provided for precise speed adjustment between minimum and maximum levels. Additionally, continuous variable speed control is possible via an external potentiometer or the Helios EUR-EC universal control system. All electrical connections are housed in a weatherproof IP65-rated terminal box mounted externally on the casing.
