Carbon dioxide is present in most buildings and usually accumulates to reach unhealthy
level (over 1,000 ppm) when there is limited ventilation. Saijo Denki Duct models
can maintain carbon dioxide level to be in good condition, which is comfortable
for healthy living and prevents experience of Sick Building Syndrome (SBS).
Volatile compounds are the toxic gases that present in indoor environment,
such as furniture, coating, and etc. One of the most commonly known TVOC is
formaldehyde, which is the derived compound extensively used in hospital settings.
Saijo Denki Duct models decrease the concentrations of TVOC and monitored
through real-time IAQ monitoring system.
