Brushless (EC)

‘Intelligent’ ventilators achieve much more than conventional ventilators without resorting to sensor control. They also use less energy and are extremely environmentally friendly. Most ventilators have to rely on external sensors and outdated control systems in order to control the power and revolutions. The Rotero EC-O obtains this information from the motor itself and controls power and revolutions by means of ‘intelligent’ electronics.

The Rotero EC-O ventilator is available in a large range of turbines: from 25 to 150 mm Ø and up to 1,000 mm long (single or double models). You can calibrate the following parameters yourself: rotation direction, soft-start, control range.
