Helios Fans RR EC 200 A

The Helios RR EC 200 A is a high-efficiency EC radial duct fan intended for direct installation within duct systems. The durable housing is crafted from galvanized sheet steel and features round connecting pieces compatible with standard pipe sizes, ensuring straightforward integration. Its radial impeller has backward curved plastic blades pressed directly onto the motor and dynamically balanced as a single unit, resulting in quiet operation and optimized efficiency. The fan is powered by an energy-saving, speed-controllable EC external rotor motor with an IP54 protection rating. This motor is maintenance-free, radio interference-free, and supported by ball bearings for long-lasting performance. Integrated electronic temperature monitoring safeguards both the motor and its electronics. The fan offers infinitely variable speed control via an internal potentiometer or an optional universal control system. Electrical connections are made through a standard IP54 terminal box mounted externally on the housing, simplifying installation and service.
