ABSTRACT:
A cage ventilation system for use in isolating a plurality of cages from an uncontrolled environment is provided, including a frame adapted to support cages in a plurality of vertically spaced shelves and an enclosure isolating all supported cages from the uncontrolled environment. A source of air from the uncontrolled environment is connected to the interior of tubes supported above each shelf in the frame, where each of the tubes has an axially disposed opening for outletting air over substantially the entire length of the associated row therebeneath. Each tube includes an interior opening which, in a plane perpendicular to the axial direction of the conduit, has an area which is less than the area of the outlet opening. The enclosure also includes an air outlet.
