Variable Air Volume (VAV) fumehood, also known as a constant velocity hood, is a hood that has been fitted with a face velocity control, which varies the amount of air exhausted from the fumehood in response to the sash opening to maintain a constant face velocity.
This allows for optimal hood performance regardless of the sash position. VAV hoods also provide significant energy savings by reducing the flow rate from the hood when the sash is closed.
A true VAV system ties the fumehood exhaust with the room’s air supply and exhaust. The VAV system can then ensure that the required room air changes per hour are being met, that sufficient make-up air is provided to balance the air that’s being exhausted, and that appropriate room temperatures are maintained.
Art Lab is proud to have one of the optimal range of VAV Fume Hoods in India.
