Helios Fans GBD EC 560

The Helios GBD EC 560 is a high-efficiency cubic ventilation unit designed for intake and extract airflows, featuring duct connectors with flexible sleeves to minimize vibration. Its adaptable side panels allow for configuration to meet various structural requirements, and installation is simplified with standard crane hook fittings.

The unit is built on a durable, self-supporting frame made from aluminium hollow sections. It features double-walled, 20 mm thick galvanized steel side panels that are internally insulated with non-combustible mineral wool for both thermal and acoustic performance. These panels can be replaced or upgraded with optional accessories such as weather louvres and condensate trays. Additional fittings like wall brackets and weatherproof roofs can be installed on the interior or exterior.

The ventilation system includes a direct-driven, backward-curved centrifugal impeller made from aluminium. It is designed for optimal energy efficiency and low noise, and is dynamically balanced with the motor to meet DIN ISO 1940 Pt.1 – class 6.3 standards.

Powering the system is a speed-controllable EC external rotor motor, known for energy efficiency and rated to IP54 for protection. The motor is maintenance-free, ball bearing mounted, and includes integrated temperature monitoring for both the motor and electronics. A built-in potentiometer allows for manual adjustment of fan speed between the minimum and maximum range. For more advanced control, the unit is compatible with an external potentiometer or the EUR-EC universal controller. All wiring is handled via a standard IP54-rated terminal box on a cable.
