The HELI HRFW 355/6 axial high-performance fan from Helios is a powerful ventilation fan designed for efficient air circulation in various applications. With a cylindrical duct made of galvanized sheet steel and flanges on both sides, this fan offers a robust and durable construction. The directly driven single-phase AC capacitor motor ensures reliable performance and is maintenance-free, minimizing operating costs. The fan is equipped with a dynamically balanced impeller optimized with profiled plastic blades to guarantee high air performance. Noise generation is reduced by sealed, low-noise ball bearings with long-term lubrication, making it ideal for applications where quiet operation is required. Additionally, the fan is speed controllable, allowing for flexible adjustment to different requirements.
