The Helios AMD 315÷2÷2 is a versatile medium-pressure axial fan designed for industrial and commercial ventilation systems that require adaptable airflow management. Featuring a 315mm diameter galvanized steel cylindrical casing with flanges compliant with DIN 24155 Part 3, it easily integrates into standard ductwork.
Powered by a 2‑pole, direct-drive 3‑phase motor with dual-speed capability, the AMD 315÷2÷2 allows flexible operation at two speeds, making it ideal for applications where varying airflow rates are necessary. The motor is maintenance-free, fitted with sealed-for-life ball bearings, and offers IP54 protection to withstand harsh environments.
The fan incorporates a 14-blade aerodynamically optimized polymer impeller, dynamically balanced according to DIN ISO 1940 – 1 (class 6.3), ensuring quiet and vibration-free operation. The unit supports speed control via voltage reduction, further enhancing its adaptability.
Suitable for air temperatures up to 40°C (controlled) or 60°C (uncontrolled), the AMD 315÷2÷2 is perfect for HVAC systems, industrial extraction, and supply ventilation where reliable, flexible performance is needed.
Combining durability, quiet operation, and adjustable speed settings, the Helios AMD 315÷2÷2 is an excellent choice for demanding ventilation applications.
