Helios Fans AMD 280/2

The Helios AMD 280/2 is a high-performance axial fan engineered for powerful air movement in industrial and commercial ventilation systems. Featuring a 280mm diameter galvanized steel cylindrical housing with DIN 24155 Part 3 flanges, the fan is built for direct integration into standard duct systems.

Driven by a 2‑pole, 3‑phase direct-drive motor, the AMD 280/2 delivers high rotational speed, providing strong airflow for systems that require high-pressure ventilation. The motor is maintenance-free, with sealed-for-life ball bearings, thermal protection, and an IP54 rating, ensuring safe and durable operation in demanding environments.

The fan incorporates a 14-blade aerodynamically optimized polymer impeller, dynamically balanced to DIN ISO 1940 – 1 (class 6.3), which reduces vibration and ensures smooth, efficient performance even at high speeds. The unit is speed-controllable via voltage reduction, allowing tailored airflow output to match various ventilation needs.

Suitable for handling air temperatures up to 40°C (controlled) or 60°C (uncontrolled), the Helios AMD 280/2 is ideal for use in HVAC systems, machinery ventilation, and industrial air extraction or supply where compact, powerful performance is required.

The AMD 280/2 combines reliability, high airflow capacity, and efficient installation, making it a versatile solution for robust ventilation needs.
