A thermoplastic laminate plank is described wherein the thermoplastic laminate plank comprises a core, a print layer, and optionally an overlay. The main airborne contamination control unit is a cabinet including a motor in communication with an air treatment path. The heat may be allowed to transfer from the heaters to at least a portion of the formation such that a drive fluid is produced in situ in the formation. The door is in the open position only after the door pivots sufficiently to move the first and second surface portions fully out of the opening, whereby birds, animals, and the like are restricted from entering the conduit. A second filter provides further filtering and amplitude control.
