Improved indoor air quality creates a healthier, more comfortable and productive workplace. Ventilation systems improve air quality by exhausting stale or polluted indoor air from a building and replacing it with "fresh" outdoor air. Proper ventilation reduces CO2 levels along with other airborne contaminants (dust, odors, moulds, moisture, etc.).
The most basic ventilation system consists of an air-handling unit with a supply air fan and control dampers. The system mixes outside air with recirculated building air and redistributes the mixed air supply within the building (see Figure 1).
Talk to your local ventilation contractor to find out which system is right for you.
