Helios Fans SB EC 160 B

The Helios SB EC 160 B is an EC centrifugal fan with a sound-absorbing housing made from galvanized sheet steel. The casing includes spigots designed for standard duct sizes and is lined internally with a 50 mm thick abrasion-resistant mineral fibreboard for noise reduction. It features a removable lid and a retractable motor and impeller assembly, providing easy access for maintenance.

The fan is fitted with a highly efficient backward curved centrifugal impeller engineered for quiet operation and dynamically balanced to ensure smooth performance.

Powered by an energy-saving, speed-controlled EC external rotor motor with IP44 protection, the motor offers maximum efficiency. It is maintenance-free, ball bearing mounted, and free from radio interference. Integrated electronic temperature monitoring safeguards both the motor and its electronics. The fan includes an internal potentiometer to adjust the speed between minimum and maximum levels, with additional stepless speed control possible through an external potentiometer or the universal EUR-EC control system. Connections are made via a standard IP54 terminal box mounted on an extended cable
