Abstract

An open fume capture and exhaust work station for a laboratory classroom having an air exhaust system that provides unobstructed sight lines for students at the station of the other students and of a classroom instructor. The work station includes an upper table surface providing a plurality of individual work surfaces, a fume extractor extending upwardly from a middle portion of the table surface to an elevation below the student sight lines, a pair of elongated air outlet openings adjacent to opposed sides of the table for directing fan generated opposed airflows to the extractor which defines opposed upstanding air inlet faces and communicates those faces with the air exhaust system creating a pressure drop within the extractor that captures the opposed inwardly airflows and pull the airflows over the individual work surfaces and into said extractor, capturing and removing emissions from spills and experiments on those work surfaces.
