Helios Fans HRFW EC 560

The Helios HRFW EC 560 is a high-performance EC axial fan designed for efficient air movement in commercial and industrial ventilation systems. Its robust cylindrical housing is constructed from galvanized sheet steel with flanges on both ends, providing strength and easy duct integration. All dimensions and flange hole patterns conform to DIN 24155 Part 2 standards. An IP55-rated external terminal box ensures safe and reliable electrical connections.

The fan features a dynamically balanced impeller made of aerodynamically optimized polymer blades, delivering high airflow with minimal noise and vibration. The impeller is suitable for operation in environments ranging from ‑30 °C to +60 °C, making it ideal for a wide range of applications.

Equipped with an energy-saving EC external rotor motor (IP54), the HRFW EC 560 offers outstanding efficiency and reliable performance. The motor is maintenance-free, operates quietly with long-life ball bearings, and meets stringent EMC standards to prevent interference with nearby electronic devices.

Integrated electronic temperature monitoring protects both the motor and electronics. Fan speed can be adjusted internally using a built-in potentiometer or externally through a variable potentiometer, three-step switch, universal controller, or differential pressure/​temperature control system. This flexibility allows for precise airflow management tailored to the installation’s specific requirements.
