Powered by an energy-saving, speed-controllable EC external rotor motor in an enclosed IP54 design, the fan offers top-tier efficiency. The motor features ball bearings with moisture protection insulation, providing maintenance-free and interference-free operation. Integrated electronic temperature monitoring protects both the motor and its electronics.
