Airflow Controls

Our range of VAV controls are designed specifically to provide variable airflow volume and ensure the safety of users working with industrial and educational fume cupboards, fume hoods and biological safety cabinets.

As many fume cupboard ventilation systems are full fresh air type a high amount of energy is wasted when the fume cupboards are not in use. Converting to VAV can reduce volumes by up to 85%, reducing both energy costs and carbon emissions. TEL offers a full retro fit service and is making a considerable impact on how organisations meet their carbon reduction targets.
