Helios Fans VDW 200/2

The Helios VDW 200/2 is a high-performance centrifugal roof fan designed for vertical discharge ventilation. It features a robust casing made from seawater-resistant aluminium with an integrated protection guard for long-lasting durability. 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 for easy connection of intake-side accessories, following DIN 24155 (page 3) standards. A bird guard, compliant with DIN EN ISO 13857, is fitted on the outlet to ensure safety and prevent debris entry.

Equipped with a backward curved centrifugal impeller made from galvanised sheet steel, the fan is dynamically balanced to DIN ISO 1940 – 1 standards, delivering smooth and efficient performance.

Power is provided by a speed-controllable, single-phase external rotor motor with IP44 protection. The motor is totally enclosed, ball bearing mounted with impregnated windings, ensuring maintenance-free, reliable, and interference-free operation.
