The Helios Fans AMD 280/4 is a robust medium pressure axial fan, specifically designed for ducted ventilation systems. It features a durable cylindrical sheet steel casing with mounting flanges on both ends, drilled to DIN 24155 Pt.3 standards for easy system integration. The elongated housing encloses both the motor and impeller, offering protection and streamlined airflow.
This model includes a high-performance axial impeller equipped with 14 aerodynamically shaped blades made from advanced polymer materials. The impeller is dynamically balanced to DIN ISO 1940 – 1, class 6.3, ensuring smooth, low-vibration operation.
Powered by a totally enclosed three-phase squirrel cage motor, the AMD 280/4 is maintenance-free and includes built-in thermal contacts for added safety. The motor supports speed control through voltage reduction and features low-noise, sealed-for-life ball bearings — ideal for continuous, reliable operation in commercial and industrial ventilation setups.
