ABSTRACT:
The rack and cage combination includes a forced air ventilation system which is automatically coupled to the cage when it is placed for storage on the rack. The forced air system includes means for directing air down onto the floor of the cage whereby vapors that normally settle at the bottom of the cage are circulated vertically toward a bonnet filter. Ventilation passages are provided around the periphery of the open top under the skirt of the filter bonnet so that gases, vapors and particulate matter can freely pass out the cage. When in the static mode, wherein the cage is disconnected from the forced air source or the forced air source is not in operation, these ventilation passages will permit air, but not particles, to freely enter the cage from the macro-environment.
