This revolutionary design consists of a new channeled filter top and exhaust port which combine with a canopy to create AllerZone™… the zone between the cage and the room.
Zone 1, The Cage:
Animal zone. Positive pressure protecting animals with HEPA filtered air.
Zone 2, AllerZone™:
Independent air pressure zone. Keeps allergens and cage particulate from escaping into the room, and prevents room air from entering the cage.
Zone 3, The Room:
Personnel zone. Reduces exposure to particulate and allergens.
In contrast with other ventilated rack systems, AllerZone™ eliminates the conflicting decision of whether your ventilated cages should be positive or negative with respect to the room. Providing the best of both worlds, AllerZone™ provides a negative pressure rack containing positive pressure cages, protecting your animals and your personnel. The removal of cages from a rack will not interrupt the balanced airflow to remaining individually ventilated cages (IVC). Well-balanced and consistent control of cage-to-cage air changes per hour (+/- 1 ACH) is the result, with any number of cages present–a feature not found among systems requiring cage level gasket seals.
AllerZone™ was tested for containment of Mouse Urine Protein (M.U.P.), a documented cause of allergic reactions with personnel. Independent certified testing confirmed M.U.P. levels were not increased in the work area using the AllerZone™ Micro-Isolator® System. Separate independent sulfur hexafluoride (SF6) tracer gas challenge testing confirmed no traceable gas leakage was detected from cages into the room or from the room into cages.
