A ventilation system for a space includes an air supply partition configured to cause filtered air to flow into an area of the space, and an air exhaust partition in spaced-apart relationship with the air supply partition and configured to cause air to be drawn in and filtered from the area. The air supply partition and the air exhaust partition create a “push-pull” air flow across the area. A ventilation partition includes air inlets in a first portion of the housing, air outlets in a second portion of the housing, a filter, and a fan configured to draw air in through the air inlets, through the filter, and out through the air outlets. The partition is a portable, free-standing structure configured to be supported by a surface, such as a floor of a room in which the partition is located.

A fume hood adapted to be connected to an exhaust system has a ventilated chamber with a rear wall, opposite side walls, a ceiling, a floor, and an access opening. A baffle assembly is located in front of the rear wall and includes a lower panel and an upper panel. The lower panel has opposite side edges extending between the chamber side walls, a lower edge spaced apart from the chamber floor, and a plurality of air-exit apertures. The upper panel has opposite side edges extending between the chamber side walls, a lower edge attached to an upper portion of the lower panel, an opposite upper edge attached to the chamber ceiling, and a plurality of air-exit apertures. An elongated grating covers a gap between the lower panel lower edge and the chamber floor and includes a plurality of air-exit apertures.

A fume hood adapted to be connected to an exhaust system has a ventilated chamber having an access opening, and at least one horizontally sliding sash or panel at the access opening that is configured to cover and uncover portions of the access opening. Each horizontally sliding panel has a peripheral edge that convexly curves into the chamber towards a centerline of the at least one horizontally sliding panel. In some embodiments, the peripheral edge is convexly curved in an arc of between about ninety degrees and about one hundred eighty degrees (90°-180°). The exhaust system creates air flow into the chamber and the curved peripheral edge produces controlled air flow patterns into the chamber. The curved edge is aerodynamically designed to help shed vortices and prevent accumulation of concentrations on the inside edge of the each panel typical of conventional fume hood sashes/panels.
