Claim:
1. A ventilated enclosure comprising: a vortex baffle mounted inside the ventilated enclosure that is a continuous, unbroken, vaulted structure that is symmetrical as viewed in profile, wherein front and rear edges of the vortex baffle form parallel lines that define a horizontal plane that is parallel to the plane of a work surface of the ventilated enclosure and perpendicular and tangential to a plane of an open face that is the sole means of communicating fluid from an outside to an interior of the ventilated enclosure; and a single exhaust slot disposed between the symmetrical vaulted interior vortex baffle and a rear housing of the ventilated enclosure, the single exhaust slot providing a sole fluid communication between the interior of the ventilated enclosure and an exhaust duct, wherein an interior height of the vortex baffle above the work surface of ventilated enclosure is equal to about 1.6 times a working depth of the ventilated enclosure; the working depth of the ventilated enclosure is equal to a distance from the work surface to a lower edge of the vortex baffle at the single exhaust slot; and a height of an opening, extending vertically from the front edge of the vortex baffle, of the ventilated enclosure is equal to or less than the working depth of the ventilated enclosure wherein the opening provides the only flow of air into the ventilated enclosure during use thereof.
