Helios Fans VDD 560/6

The Helios VDD 560/6 is a high-performance centrifugal roof fan designed for vertical air discharge applications, offering efficient airflow and durable construction. Its seawater-resistant aluminium casing includes an integrated protection guard for enhanced corrosion resistance and safety.

The fan’s motor support and base plate are made from galvanized steel and incorporate an inlet cone for optimal airflow management. Threaded bolts on the base plate facilitate easy mounting of intake-side accessories, conforming to the DIN 24155 hole pattern (page 3). A bird guard compliant with DIN EN ISO 13857 is provided on the discharge side as standard.

Equipped with a high-efficiency backward curved centrifugal impeller constructed from aluminium, the unit is dynamically balanced to DIN ISO 1940 – 1 standards to ensure smooth and vibration-free operation.

The fan is driven by a speed-controllable, totally enclosed three-phase external rotor motor with IP 54 protection. Featuring ball bearings with impregnated windings, the motor requires no maintenance and includes radio interference suppression, making the VDD 560/6 a reliable solution for demanding ventilation needs.
