Using thimbles to connect Biological Safety Cabinets to Variable Air Volume (VAV) Exhaust Systems
Abstract Variable-volume exhaust systems are a common feature of laboratory ventilation designs. By reducing exhaust airflow in proportion to the actual need, the system uses less energy to condition the make-up air. However, variable exhaust flows can disturb the critical pressure relationships between air flows in biological safety cabinets, which require a constant airflow to maintain ...
