Integrated Variable Air Volume System

Integrated VAV - System On Nova Guard FumeHood
System shown on NovaGuard™ fume hood
The Integrated Variable Air Volume (VAV) system is designed to provide variable airflow volume control and to ensure a safe face velocity for the operator. Properly used VAV systems provide a clear energy conservation advantage over Constant Air Volume systems which consume a large volume of energy when the fume hoods are not in use. Switching to VAV can decrease exhaust volumes by up to 85%, reducing energy costs and carbon emissions. The system measures face velocity, sash position and automatically reduces the exhaust volume as the sash is lowered, thereby saving significant energy and costs. This system is designed to be factory mounted on any Mott fume hood.
