Carbon dioxide (CO2) is a natural product of the human (and other mammals’) respiratory process.
The air we breathe is made up of about 20% oxygen, 0.03% CO2 and the rest Nitrogen. We exhale about 16% oxygen and 4% CO2, with the recommended maximum CO2 level for 8 hours of exposure set by The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Air Quality Standards at 0.1% or 1,000 parts per million (PPM).
To keep the CO2 level to less than 1,000 PPM requires at least 15 cfm of air per person. One of the first symptoms of high CO2 levels is drowsiness, and if conditions worsen, higher levels of carbon dioxide can cause headache, dizziness, and nausea.
The UltimateAir® RecoupAerator®’s optional CO2 sensor monitors the amount of carbon dioxide in an enclosed area. Based on its preset function, it signals to the RecoupAerator® to increase airflow and ventilation when CO2 levels reach an undesired level.
RecoupAerator® owners have the option of selecting trip points between 800 – 1200 PPM , increasing the ventilation rate to deliver more oxygen rich air from outside and exhaust the higher inside CO2 levels. When the CO2 falls below the preset level, the RecoupAerator® will reduce the airflow to normal ventilation setting.
When to use the CO2 Monitor Switch
Whether it’s for the home or business, the CO2 monitor may be a necessary feature as part of your RecoupAerator® purchase and is recommended for:
