The Variable Air Volume (VAV) Fume Hood from LOC Scientific represents a state-of-the-art solution for laboratories needing precise airflow control. This advanced fume hood is engineered to adjust airflow dynamically based on the laboratory's needs.
Unlike traditional constant air volume systems, the VAV Fume Hood integrates seamlessly with exhaust control systems from other manufacturers to dynamically adjust the volume of air being exhausted based on the position of the sash. This innovative approach maintains a constant face velocity, ensuring superior performance while significantly reducing energy costs.
