Helios Fans VDD 560/6 T120

The Helios VDD 560/6 T120 is a centrifugal roof fan designed for vertical air discharge and continuous operation in high-temperature environments, with a maximum airflow temperature rating of 120°C. It is specifically suitable for kitchen exhaust applications in compliance with VDI 2052 standards. The motor is positioned outside the airflow to ensure durability and efficiency.

The casing is made of seawater-resistant aluminium and includes an integrated protection guard for added security. The motor support and base plate are constructed from galvanized steel and feature an inlet cone. Threaded bolts on the base plate allow for easy attachment of intake air accessories, conforming to the DIN 24155 hole pattern (page 3). A bird guard compliant with DIN EN ISO 13857 is installed on the outlet as standard.

Equipped with a high-efficiency backward curved centrifugal impeller made from aluminium, the fan is dynamically balanced according to DIN ISO 1940 – 1 to minimize vibration and ensure smooth operation.

Power is provided by a speed-controllable, totally enclosed three-phase external rotor motor with IP54 protection. The motor features ball bearings with impregnated windings, requires no maintenance, and is designed with radio interference suppression for reliable and quiet performance.
