Abstract

An animal cage rack includes a forced air system for removing air from the periphery of the animal cages. The rack includes 'U' shape guides for positioning and aligning each cage with respect to a positive ventilating probe and an automatic watering device. Each cage includes a top bonnet section, a bottom section which supports the bonnet around the periphery thereof, a flat rim wire bar lid, and a filter in the bonnet. An L-shaped spacer separates the bonnet from the bottom section so that air exhaust ports in the U-shaped guide can remove exhausted air from the periphery of the cage. Positive air supplied by an air inlet manifold is introduced through an aperture in the bonnet and the L-shaped bracket, to the top of each cage. A downwardly facing port in the air tube forces air toward the bottom of the cage which after it circulates is removed through the periphery by the exhaust ports in the U-shaped cage guides.
