Helios Fans VDW 180/2

The Helios VDW 180/2 is a centrifugal roof fan designed for vertical discharge applications. It features an efficiency-optimized casing made from seawater-resistant aluminium with an integrated protection guard, ensuring durability in various environmental conditions. The motor support and base plate are constructed from galvanised steel and include an inlet cone for enhanced airflow management. The base plate is equipped with threaded bolts for easy attachment of intake air accessories, following the DIN 24155 hole pattern (page 3). A bird guard compliant with DIN EN ISO 13857 is fitted on the outlet as standard to prevent bird ingress.

This fan uses a high-efficiency backward curved centrifugal impeller made from durable polymers, dynamically balanced according to DIN ISO 1940 – 1 to minimize vibration and noise during operation.

Power is provided by a speed-controllable, totally enclosed single-phase external rotor motor with IP44 protection. The motor features ball bearings with impregnated windings, offering maintenance-free and radio-suppressed performance for reliable and quiet operation.
