The Helios radial duct fan is an efficient solution for ventilation in various applications. With a robust housing made of galvanized steel and round connection flanges compatible with standard pipes, this fan offers reliable performance. It is specifically designed for the transport of medium and small air volumes against high resistance. The fan features a radial impeller with backward-curved blades made of plastic, which is directly pressed onto the motor and dynamically balanced as a unit. This ensures quiet operation and high efficiency. The single-phase external rotor motor is maintenance-free and equipped with thermal contacts as well as low-noise ball bearings that provide long-term lubrication. Power control can be achieved via an electronic controller or a step transformer, allowing for flexible adjustment to specific requirements.

• Two power levels for flexible application possibilities
• Maintenance-free motor with integrated thermal contacts
• Low-noise ball bearings with long-term lubrication
• Dynamically balanced impeller for high efficiency.
