The Helios AMW 250/2 is a medium pressure axial fan featuring a cylindrical duct casing with flanges on both sides, designed according to DIN 24155 Pt.3 for straightforward installation. The long sheet steel duct casing houses the axial impeller and motor, ensuring a durable and compact design.
The fan incorporates a 14-blade polymer impeller, aerodynamically profiled and dynamically balanced to DIN ISO 1940 – 1 class 6.3 for smooth, low-vibration operation. Powered by a totally enclosed, maintenance-free AC condenser motor with built-in thermal contacts, this fan allows speed control via voltage reduction. It also includes low-noise sealed-for-life ball bearings and is designed for non-reversible operation.
