The HELI HWD 355/4 axial high-performance fan from Helios is a powerful ventilation fan designed for efficient air circulation in various applications. With an air flow rate of 2900 m³/h, this fan provides an effective solution for ventilating spaces where a high air exchange rate is required. The fan comes equipped with a wall mounting ring and an intake nozzle, allowing for easy installation. Its construction from galvanized steel sheet ensures durability and resilience, while the aerodynamically optimized blades of the impeller guarantee high performance with reduced noise levels. The three-phase squirrel cage motor allows for flexible speed control, making the fan particularly adaptable to different operating conditions. The closed design and maintenance-free, low-noise ball bearings contribute to the reliability and efficiency of the device.
