Laboratory Airflow Control System's Requirements for Fume Hood Containment

Ken Crooks, Phoenix Controls

The laboratory airflow control systems' (LACS) primary responsibility is accurate and responsive airflow control at the fume hood level to aid in proper containment of fumes and vapors. This demonstration will show how sash position sensing, coupled with fast venturi valve re-positioning and user presence sensing, provides the highest level of LACS performance while also providing the greatest energy savings potential. Smoke visualization will be used to demonstrate the containment and performance of the LACS. For attendees unfamiliar with LACS performance requirements, this demonstration will provide insight into the critical factors (beyond hood design) that affect fume hood containment.
