Contributing to a comfortable classroom environment! Ventilation fan controller 'ARU-03C/ARU-05C' equipped with a CO2 sensor.
The 『ARU-03C/ARU-05C』 is a ventilation fan controller that can automatically control the on/off (or high/low) operation of the ventilation fan according to the level of air pollution. The sensitivity can be switched between three levels (for CO2 concentration: 1400ppm/1000ppm/800ppm), allowing for adjustments based on purposes such as infection control and school hygiene standards. By reducing unnecessary intake of outside air, it significantly cuts down on heating and cooling costs as well as CO2 emissions, achieving energy savings. 【Features】 ■ Controls the ventilation fan according to air pollution levels ■ Three levels of sensitivity adjustment ■ Significantly reduces heating and cooling costs and CO2 emissions ■ Equipped with a CO2 sensor ■ Equipped with an air pollution sensor (ARU-05C) *For more details, please refer to the PDF document or feel free to contact us.
