The Helios AMW 280/2 is a medium pressure axial fan designed with a cylindrical duct casing constructed from sheet steel, including flanges on both sides with hole patterns to DIN 24155 Pt.3 for straightforward installation. The casing encloses the impeller and motor for reliable performance.
This fan features an axial impeller with 14 aerodynamically profiled polymer blades, dynamically balanced to DIN ISO 1940 – 1 class 6.3, ensuring low vibration and smooth operation. The motor is a totally enclosed AC condenser type, maintenance-free, with built-in thermal contacts for protection. It allows speed control by voltage reduction and is equipped with low-noise sealed-for-life ball bearings. The motor is designed for non-reversible operation.
