• For ordinary duct, when the static pressure exceeds the expected range, it is fairly dicult even for an
experienced installer to calculate and adjust the air volume precisely.
• With constant air volume control technology, the duct will automatically adjusts to perfect static pressure and
keep constant air volume.
