The Helios SB EC 400 A is an EC centrifugal fan engineered for quiet, efficient ventilation. Its casing is made of galvanized sheet steel with round connectors designed for standard duct systems. The interior includes a perforated metal lining and a 50 mm thick mineral fibre board for effective sound absorption. The fan features a swing-out cover for easy access, and the motor and impeller unit is retractable for convenient maintenance.
This fan incorporates a highly efficient backward curved centrifugal impeller, dynamically balanced to ensure smooth and quiet operation.
It is powered by a speed-controlled, energy-saving EC external rotor motor with IP44 protection, offering maximum efficiency. The motor is maintenance-free, ball bearing mounted, and free from radio interference. Integrated electronic temperature monitoring protects the motor and electronics. The fan includes an internal potentiometer for adjusting speed within the full range, with additional stepless speed control options available via an external potentiometer or the universal EUR-EC control system. Electrical connections are provided through a standard IP54 terminal box mounted on an extended cable.
