Abstract:
An assembly for collection and removal of solids, amalgam and particulate matter from a dental operatory air stream created by a vacuum means comprising:a first separation chamber positioned between a vacuum means and said dental operatory, said first separation chamber having an inlet means for the introduction of air, effluent, solids, amalgam and particulate matter from said dental operatory; a first outlet means in communication with a vacuum source for the exhaust of air; a second outlet means from said first separation chamber in communication with a second chamber for the exhaust of effluent, solids, amalgam and particulate matter to said second chamber for the separation of effluent from solids, amalgam and particulate matter and collection of solids, amalgam and particulate matter by gravitational sedimentation in the said second chamber, said effluent discharged to a sewer, said second chamber removably replaceable allowing for the recycling and recovery of solids, amalgam and particulate matter collected therein; and a vacuum sensor and timer relay for sensing the absence of vacuum in said first separation chamber and activating a valve for transferring said effluent, solids, amalgam and particulate matter via second outlet means to said second chamber.
