<p>A protected conveyor for a spray chamber or spray booth is provided with a pressurized housing and an air curtain means which substantially isolates the conveyor from the deleterious fluids within the spray booth and substantially isolates the articles from droppings from the conveyor. More specifically, a blower supplies air under pressure to a plenum connected to a nozzle means which discharges a thin curtain of air transversely across a slot in the housing wall and transversely across depending conveyor hangers extending downwardly through the slot. The blower also supplies air under pressure to the housing to provide air discharge out of the housing slot. The transverse air discharge combines with and redirects the air discharge through the slot as common continued air movement transversely away from the conveyed articles and toward an external air exhaust from the booth. The housing, conveyor and air curtain means are formed in an inexpensive manner.</p> |
