Helios HWW 400/4 TK

The HWW 400/4 TK from Helios is a powerful axial high-performance fan designed for efficient ventilation in various applications. Equipped with a robust wall mounting ring and an intake nozzle, this fan provides reliable air circulation. The wall ring made of galvanized steel sheet is double-coated for durability and corrosion resistance. The impeller features profiled plastic blades that are aerodynamically optimized to ensure high performance. The fan is powered by a maintenance-free single-phase AC capacitor motor, which has a closed design and is equipped with thermal contacts in the winding for added protection. Noise generation is minimized by sealed ball bearings with long-term lubrication, and the speed can be controlled by reducing voltage, allowing for flexible adaptation to specific requirements.

• High-performance impeller with profiled blades for optimized aerodynamics
• Maintenance-free capacitor motor with integrated thermal contacts
• Quiet ball bearings with long-term lubrication
• Reversible operation mode for flexible applications
