    • The present invention is related to a cage rack system (1) for animals, particularly for laboratory animals. This system can accommodate or comprises a plurality of cages (4) ventilated individually or in groups. At least the majority of the cages (4) comprise at least one air-inlet (41) and at least one air-outlet (42). The cages (4) can be selected according to the race, size, the number and/or conditions of the animals. The invention further comprises an air guidance system (2) for delivering air to the air-inlet (41) and/or collecting air from the air-outlet (42) with integral or separated conduits (21-24). Further, there is provided at least one sampling unit (3) for collecting airborne particles from the air, the sampling unit (3) being adapted to collect the airborne particles by a cyclonic flow path to cause a separation of the particles from the air. The sampling unit (3) can have one or more components and can be arranged for analysing, evaluating, controlling and/or monitoring the incoming air and/or the outgoing air. The incoming air can be checked in order to have a basis for comparing the respective results with the results from one or more components of the air guidance system analysing, evaluating, controlling and/or checking the outgoing air. Alternatively or additionally to the cyclone the sampling unit (3) can be provided so as to be replacably insertable in one or more of the conduits (21-24).
    • 本发明涉及用于动物的笼架系统(1),特别是用于实验动物。 该系统可容纳或包括单独或分组通风的多个笼子(4)。 至少大部分的保持架(4)包括至少一个空气入口(41)和至少一个空气出口(42)。 笼子(4)可以根据种族,大小,动物的数量和/或条件进行选择。 本发明还包括用于将空气输送到空气入口(41)和/或从具有整体或分离的导管(21-24)的空气出口(42)收集空气的空气引导系统(2)。 此外,提供了用于从空气中收集空气中的颗粒的至少一个取样单元(3),所述取样单元(3)适于通过旋流流动路径收集空气中的颗粒,以使颗粒与空气分离。 采样单元(3)可以具有一个或多个组件,并且可以被布置用于分析,评估,控制和/或监视进入的空气和/或输出空气。 可以检查进入的空气,以便具有将各个结果与空气引导系统的一个或多个部件的结果进行比较的基础,分析,评估,控制和/或检查出口空气。 替代或附加于旋风分离器,采样单元(3)可以被设置成可替换地插入到一个或多个导管(21-24)中。
