Abstract

Means and methods for maintaining laboratory work stations which have essentially open work areas, free of noxious and malodorous air contaminants by the use of tempered induction air combined with contaminant bearing exhaust air to limit the throughput of more expensive conditioned air. The means enables both the utilization of an integral lighting unit and the efficient collection of noxious air without creating unwanted drafts and currents.
