Helios Fans VDD 560/4 T120

The Helios VDD 560/4 T120 is a specialized centrifugal roof fan designed for vertical discharge and continuous operation in environments with air temperatures up to 120°C. Ideal for kitchen exhaust ventilation in accordance with VDI 2052, this fan ensures reliable performance under demanding conditions.

Its corrosion-resistant casing is made from seawater-resistant aluminium and includes an integrated protection guard for enhanced durability and safety. The motor support and base plate are constructed from galvanized steel, featuring an inlet cone to optimize airflow. The base plate is equipped with threaded bolts to facilitate the secure attachment of intake-side accessories, following the DIN 24155 hole pattern (page 3). A bird guard is fitted on the outlet side as standard, complying with DIN EN ISO 13857.

The fan utilizes a high-efficiency backward-curved centrifugal impeller made from aluminium, dynamically balanced according to DIN ISO 1940 – 1 to ensure smooth, low-vibration operation.

Power is supplied by a speed-controllable, totally enclosed three-phase external rotor motor with IP54 protection. The motor’s ball bearings feature impregnated windings for maintenance-free operation and include radio interference suppression, making the VDD 560/4 T120 a dependable and efficient solution for high-temperature ventilation needs.
