The HELI RR EC 200 A EC radial duct fan is a powerful ventilation fan designed for direct installation in duct systems. With a housing made of galvanized steel sheet and round connection flanges compatible with standard ducts, this fan offers a robust and durable solution for various ventilation applications. The radial impeller with backward-curved plastic blades ensures a high air flow rate of up to 1002 m³/h and is directly pressed onto the motor, allowing for dynamic balancing as a unit. The energy-efficient EC external rotor motor is speed-controllable and provides high efficiency while operating quietly. With integrated electronic temperature monitoring and an IP54 protection rating, the fan is both maintenance-free and resistant to radio interference, making it ideal for use in demanding environments.
