Helios Fans GBD EC 560 T120

The Helios GBD EC 560 T120 is a robust cubic exhaust unit designed for high-temperature environments, capable of handling air up to 120°C. It features supply and extract duct adapters with low-pressure loss and integrated flexible sleeves that reduce vibration transmission. With a motor mounted outside the airstream, the unit is ideal for extracting contaminated or hot air. It includes a built-in condensate collector and enclosed drainage system, making it particularly suitable for commercial kitchens and process ventilation systems. Installation is straightforward with standard crane hook compatibility.

Its housing consists of a self-supporting aluminium frame and double-walled, 20 mm thick galvanized steel side panels, internally lined with non-combustible mineral wool for both sound and thermal insulation. These panels can be replaced or adapted using accessories such as weather louvres and condensate trays. Additional components like wall brackets and protective roofs can be added internally or externally.

Air movement is provided by a backward-curved, free-running centrifugal impeller made from aluminium, directly driven and designed for energy efficiency and quiet operation. The impeller is dynamically balanced together with the motor in accordance with DIN ISO 1940 Pt.1 – class 6.3.

The unit is powered by an enclosed EC internal-rotor motor, located outside the airflow, offering speed control and high efficiency. With IP54 protection and ball bearing support, the motor is maintenance-free and interference-resistant. It features integrated electronic temperature monitoring and includes a built-in potentiometer for adjusting speed between the minimum and maximum range. For external control, it supports both a separate potentiometer and the EUR-EC universal control system. Power and control signal connections are handled directly within the unit at the integrated EC controller.
