Helios RR EC 250

The Helios RR EC 250 is a powerful EC radial duct fan designed for direct mounting in duct systems. With a housing made of galvanized sheet steel and round connection flanges compatible with standard ducts, this fan offers a robust and durable solution for ventilation technology. The radial impeller with backward-curved plastic blades ensures a high air flow rate of up to 1195 m³/h and is directly pressed onto the motor, allowing for dynamic balancing as a unit. The fan operates quietly and features a high efficiency, making it an energy-efficient choice for various applications. The integrated EC external rotor motor is speed controllable and offers an IP 44 protection rating, making it ideal for use in different environments. Additionally, the fan is maintenance-free and interference-free, further reducing operating costs.
