Helios Fans AMD 225/2

The Helios AMD 225/2 is a high-performance medium-pressure axial fan designed for efficient air movement in various industrial and commercial ventilation systems. Its robust construction includes a galvanized sheet steel cylindrical casing with flanges on both ends, conforming to DIN 24155 Part 3 standards, ensuring easy integration into ductwork systems.

Equipped with a 14-blade aerodynamically profiled polymer impeller, the fan delivers smooth airflow with minimal noise and vibration. The impeller is dynamically balanced to DIN ISO 1940 – 1, class 6.3, promoting low-vibration operation .

The fan is powered by a totally enclosed 3‑phase squirrel cage motor, featuring built-in thermal contacts for protection, maintenance-free operation, and low-noise sealed-for-life ball bearings. The motor is speed-controllable via voltage reduction, allowing flexibility in airflow management .

With a nominal diameter of 225mm, the AMD 225/2 offers a free-blowing airflow rate of 1950 m³/​h and an operating point airflow of 1000 m³/​h at 50 Pa pressure increase. It operates at 2760 RPM, with a nominal power of 250 W, and is suitable for air temperatures up to 40°C (controlled) or 60°C (uncontrolled). The unit carries an IP54 protection rating, ensuring durability in demanding environments .

Ideal for applications requiring reliable and efficient ventilation, the Helios AMD 225/2 combines performance, durability, and ease of installation.
