The CO₂ Sensor has three operating levels: 30%, 50%, and 100% of its capacity, depending on the CO₂ levels. With a CO₂ level below 650 ppm, the fan operates at 30%. Between 650 and 950 ppm, the fan operates at 50%. Above 950 ppm, the fan operates at 100% of its capacity.
The selection of the fan and filters to be used should follow the recommendations and guidelines of the project, just like any other air renewal system.
The same sensor can control up to two fans simultaneously. Its operating logic follows the RE-09 recommendation of ANVISA, which sets a maximum CO₂ concentration limit of 1000 ppm in the environment. It is recommended to install the sensor on the ceiling or, at a minimum, at a height of 2.0 meters on the wall.
