ABSTRACT:
An air canopy ventilation system is disclosed which comprises a surface having two substantially parallel spaced apart side walls surmounted at their respective upper edges by a canopy. A vent means having a plurality of outlets extends between the side walls and substantially the whole length of the front edge of the surface. A fan means connected to the vent means is adapted to drive a flow of air through the vent means upwardly to form a curtain of air over the front of the system, thereby entraining within the area fumes and odors. The upwardly flowing air, fumes and odors are removed by an exhaust means. The exhaust means can include a filter means and a return air means. The system has applications in commercial cooking systems, laboratories, and areas requiring removal of fumes and gases from an enclosed working surface.
