Abstract
A laboratory bench assembly having work stations which are retractable into the interior of the bench to provide a clear and unobstructed bench space when not in use; an air flow is created within said bench by a blower, the air flow carrying dust particles from each work station through a conduit into a cartridge-type filter which traps and collects the dust particles; a jet shoots a blast of high pressure air into said filter for cleaning purposes.
