Patent number: 8544416Abstract: A ventilated cage and rack system for assembly by a user using simple tools and a method for assembly is provided. A plurality of frames and vertical plenums can be connected to a base, and a retaining assembly can be used to connect a plurality of vertical beams and horizontal support beams. A plurality of canopies is preferably used to connect the plenums and the support beams to shroud cages beneath the canopies. The canopies preferably include removable side walls to adapt to the width of the cage being shrouded. A plenum clean out system preferably provides a relatively simple method of draining a cleaning fluid from a plenum by moving a lever between an open and closed position. A pressure based plenum system is also provided wherein a constant air pressure is maintained in the ventilated rack system and air is provided into a cage at a constant air pressure.Type: GrantFiled: October 12, 2007Date of Patent: October 1, 2013Assignee: Lab Products, Inc.Inventors: George S.

Patent number: 6729266Abstract: An animal isolation and caging system which maximizes cage density within a ventilated rack is provided. The rack includes at least one air exhaust plenum, and at least one canopy disposed within the rack for ventilation of the cages housed in a rack system. The rack is capable of supporting a first cage within the rack below a first canopy, and also positioning a second cage below a second canopy. The filter top of the first cage provided by the invention also provides a filter retainer having a filter top retainer wall designed to be in contact with a first canopy unit forming an enclosed space so configured as to create an enclosed space from which the animal isolation and caging system of the invention creates a zone of negative pressure so as to permit air to be drawn into an air exhaust plenum or duct from the interior of the first cage through the top of the first cage.Type: GrantFiled: November 3, 2000Date of Patent: May 4, 2004Assignee: Lab Products, Inc.Inventors: George S.
