Helios Fans GBD EC 630 T120

The Helios GBD EC 630 T120 is a durable cubic exhaust unit engineered for high-temperature applications, capable of handling air temperatures up to 120°C. It includes low-resistance duct adapters with flexible sleeves to reduce vibration transmission and adaptable side panels to fit various structural requirements. The motor is mounted outside the airflow, making the unit suitable for extracting hot and contaminated air. It is equipped with a condensate collector and enclosed drainage system as standard, making it ideal for commercial kitchen environments and process ventilation systems. Installation is simplified by standard crane hook fittings.

The unit’s enclosure features a self-supporting frame made from aluminium hollow sections and double-walled side panels that are 20 mm thick, constructed of galvanized sheet steel. These panels are lined internally with non-combustible mineral wool for sound and thermal insulation. The side panels are replaceable and can be fitted with optional accessories like weather louvres and condensate trays. Additional components, such as wall brackets and weather protection roofs, can be mounted inside or outside the unit as required.

Air movement is generated by a direct-driven, free-running backward-curved centrifugal impeller made from aluminium, designed for energy efficiency and quiet operation. The impeller and motor assembly is dynamically balanced according to DIN ISO 1940 Pt.1 – class 6.3 standards to ensure smooth performance.

The unit is powered by an enclosed EC internal-rotor motor located outside the airflow, providing variable speed control and rated to IP54 for protection. The motor is maintenance-free, ball bearing supported, and interference-resistant. It features integrated electronic temperature monitoring for both motor and electronics. A built-in potentiometer allows for manual speed adjustment between minimum and maximum limits. The system supports stepless speed control through an external potentiometer or the EUR-EC universal controller. Power and control signal connections are handled directly within the unit via the integrated EC controller.
