ABSTRACT:
An animal housing and service system of the type having impervious cage boxes suspended on brackets from internally-ducted shelves is provided with flat foraminous filter panels disposed across the open tops of the cage boxes, the filter panels remaining in position when the boxes are mounted in the shelves. An independently-ventilated service enclosure is provided for receiving cage boxes, the service enclosure having air direction panels adapted to achieve a downward flow across the cages to be serviced. By keeping the filter panels in place on the cages except when the cage is in the service enclosure, the system achieves the powered ventilation benefits of integrally-ducted shelves and the positive isolation from pathogens of filter covers.
