Maintaining the proper air quality level is essential for keeping compressed air energy costs down and to ensure reliable production. Poor air quality can have a negative effect on production equipment and can increase energy consumption and maintenance needs.
The quality of air produced should be guided by the quality required by the end-use equipment
Indoor air quality must be great enough to provide effective ventilation and prevent temperature stratification, but must not be so strong that it makes the place feel drafty(windy)
Air movement affects comfort. Cool, dry air circulated past a warm body will speed heat flow from the body.
