  • Easily installed in offices, buildings, shopping centres, churches, hotels, conference rooms to monitor the IAQ (indoor air quality, CO2/VOC) and control the fresh air intake fan only when required, instead of running the fan all the time. This way one can save 40-80% on energy cost and thereby save green house gases to get carbon credit
