The HELI HRFD 560/4 axial high-performance fan from Helios is a powerful ventilation fan designed for demanding applications. With a cylindrical duct made of galvanized steel sheet and flanges on both sides, this fan offers a robust and durable construction. The impeller, featuring seven blades made of fiberglass-reinforced plastic (GRP), ensures high efficiency and effective air circulation. The fan is equipped with a three-phase squirrel-cage motor that allows for stepless speed control via a frequency inverter. This makes it particularly flexible and adaptable to various operating conditions. The closed design and low-noise ball bearings with long-term lubrication contribute to the maintenance-free operation and longevity of the device. The HELI HRFD 560/4 is therefore an ideal choice for applications requiring reliable and efficient ventilation.
