<p>A containment, such as a glovebox (3), includes an extract system comprising an extract suction means, a filter housing (4), and a vortex amplifier (1) controlling the extent of suction by the suction means from the containment, wherein the vortex amplifier is removably mounted in an opening in a wall (2) of the containment, and the filter housing is mounted relative to the containment in such a manner that a filter (22) within the housing can be posted through an opening into the containment. The vortex amplifier is removable for cleaning. The filter housing may be mounted on the exterior of the containment in-line with the opening in which the vortex amplifier is mounted whereby the housing can be posted through the opening in which the vortex amplifier is mounted upon removal of the vortex amplifier.</p> |
