Helios Fans GBW EC 315 A T120

The Helios GBW EC 315 A T120 is a robust cubical exhaust unit engineered for demanding applications involving hot air extraction, such as commercial kitchens and industrial process ventilation systems. It features supply and extract duct adapters designed to minimize pressure loss, complete with flexible sleeves that reduce vibration transmission and withstand temperatures up to 120°C.

The motor is positioned outside the airflow, allowing the unit to handle extraction of dirty and hot air safely and reliably. Included as standard are a condensate collector and enclosed condensation discharge, ensuring efficient moisture management. Installation is straightforward with standard crane hooks facilitating positioning.

Constructed with a self-supporting aluminium hollow section frame, the unit is clad in double-walled, 20 mm thick galvanised sheet steel panels. These panels are insulated with non-combustible mineral wool to provide excellent sound and heat insulation. The enclosure panels are replaceable and compatible with various accessories, including weather louvres and condensate trays. Additional mounting options such as wall brackets and weather protection roofs are available for both internal and external installation.

The fan is equipped with a free-running, backward curved centrifugal impeller made from aluminium, directly driven for optimal efficiency and low noise operation. The impeller and motor are dynamically balanced to meet DIN ISO 1940 Pt.1 class 6.3 standards, ensuring vibration-free performance.

Powering the fan is an energy-saving, enclosed EC internal-rotor motor located outside the air stream, rated with IP54 protection for dust and moisture resistance. This maintenance-free motor is interference-free and mounted on durable ball bearings. It features integrated electronic temperature monitoring to safeguard both motor and control electronics.

Speed regulation is flexible, with a built-in internal potentiometer allowing stepless adjustment of fan speed from minimum to maximum. Further options include control via an external potentiometer or integration with the universal EUR-EC control system. Electrical connections for mains supply and control signals are made directly at the EC controller within the unit.

The Helios GBW EC 315 A T120 provides an efficient, reliable, and adaptable solution for high-temperature ventilation requirements in commercial and industrial environments.
