The HELIOS HQW450/4 TK high-performance fan is a powerful axial fan designed for efficient ventilation in various applications. With its square mounting plate and integrated intake nozzle made of galvanized steel sheet, it offers a robust and durable construction. The fan is equipped with a high-performance impeller optimized with profiled plastic blades to ensure a high air flow rate of up to 5770 m³/h. The directly driven single-phase AC capacitor motor is maintenance-free and features integrated thermal contacts for added safety. The sealed, low-noise ball bearings with long-term lubrication contribute to the longevity and efficiency of the device. Additionally, the fan is speed controllable, allowing for flexible adjustment to meet specific requirements. With its IP55 classification, it is also suitable for use in demanding environments.
