Helios Fans SKRD EC 560÷100÷50 B

The Helios SKRD EC 560÷100÷50 B is a rectangular EC centrifugal fan designed for inline installation in rectangular duct systems. The compact casing, made of galvanised steel and flanged on both ends, is acoustically lined with 50 mm thick mineral fibreboard for effective sound insulation. The fan is service-friendly with a swing-out motor and impeller unit, allowing easy cleaning and maintenance.

Equipped with a centrifugal backward curved impeller made from durable polymer, this fan ensures low noise operation through dynamic balancing and features aerodynamic optimisation with intake airflow facilitated by an inlet nozzle.

Powered by an energy-saving, speed-controlled EC external rotor motor with IP54 protection, the fan delivers maximum efficiency. The motor is maintenance-free, ball bearing mounted, and radio interference-free, with integrated electronic temperature monitoring for both motor and electronics. Speed control is stepless, with a standard internal potentiometer for setting any fan speed between minimum and maximum. Additional control options include external potentiometer or universal control system EUR-EC. Electrical connection is provided via a standard terminal box (IP54) mounted on an extended cable.
