Helios Fans GBW EC 250 T120

The Helios GBW EC 250 T120 is a high-performance cubical exhaust unit specially engineered for extracting hot, dirty air up to 120°C, making it ideal for commercial kitchens and process ventilation systems. It includes supply and extract duct adapters with flexible sleeves designed to minimize vibration transmission, suited to withstand temperatures up to 120°C. The motor is located outside the airflow, ensuring durability and suitability for harsh, high-temperature environments.

The unit features a self-supporting frame made from aluminium hollow sections, combined with double-walled 20 mm thick galvanised sheet steel side panels. These panels are insulated with non-combustible mineral wool for effective sound and heat insulation. Panels can be replaced or customized with accessories such as weather louvres and condensate trays. Additional optional components include wall brackets and weather protection roofs, which may be mounted internally or externally as needed.

Equipped with a free-running backward curved centrifugal impeller made from aluminium, the unit delivers energy-efficient airflow with minimal noise. The impeller and motor are dynamically balanced to meet DIN ISO 1940 Pt.1 quality class 6.3 standards, ensuring smooth and vibration-free operation.

Powered by an enclosed, energy-efficient EC internal rotor motor positioned outside the air stream, the fan provides speed control and protection class IP54. The motor is maintenance-free, interference-free, and ball bearing-mounted for long service life. Integrated electronic temperature monitoring protects both the motor and control electronics.

Speed control is easily adjustable via an internal potentiometer allowing continuous settings between minimum and maximum speeds. Additional control options include an external potentiometer or a universal control system (EUR-EC). Electrical connections for power and control signals are conveniently integrated directly into the unit at the EC controller.

The GBW EC 250 T120 offers reliable, efficient, and robust ventilation for demanding environments requiring hot air extraction with superior control and low vibration.
