A rack system for holding a number of individual drawers or cages for laboratory or other animals has a plenum array for providing fresh air and removing stale or contaminated exhaust air from the drawers. A constant volume inlet valve and a constant volume outlet valve provide for stable air flow within each individual drawer while the exhaust air is expelled to a low pressure exhaust duct.
