VAV System – Fume Cupboards

The InnoGUARD VAV System (Variable Air Volume) integrates both the fastest and most stable air volume control in a fume hood. With variable airflow, you always have the amount of airflow needed at the desired door opening, instead of having a constant maximum airflow all the time. Higher airflows are no better as too high airflows create turbulence and actually make it less safe to work!

Huge energy savings
Several parameters contribute to large energy savings:

• Primarily, the system controls the air volume through the front glassdoor opening.
• Secondly, the system controls the air volume of the air velocity sensor.
• The system also uses presence control as a parameter to know when it is possible to reduce airflow and save additional energy.
