Helios HELI HQD 315/8/4 Axial high-performance fan 3-PH, pole-changing, Dahlander

The HELIOS HQD 315/8/4 axial high-performance fan is a powerful ventilation fan designed for efficient air circulation in various applications. With its square mounting plate and integrated inlet nozzle made of galvanized sheet steel, it offers a robust and durable solution for ventilation. The fan is directly driven and features a rotor with seven blades made of thermoplastics, ensuring high efficiency and low operating noise. The dynamic balancing guarantees vibration-free operation, which extends the device's lifespan and minimizes noise levels. The three-phase short-circuit rotor motor with Dahlander winding allows for flexible speed adjustment, while the closed design and maintenance-free, low-noise ball bearings with long-term lubrication reduce maintenance efforts. This fan is therefore an ideal choice for applications requiring reliable and efficient air circulation.

• High air flow rate of 2060 m³/h for effective ventilation
