A fluid delivery system for delivering a fluid from an automatic water source to animals housed in cages in high density caging systems may comprise a fluid delivery valve assembly, wherein the fluid delivery valve assembly is adapted to be coupled to the automatic water source to facilitate the provision of fluid to animals housed in the cages. The fluid delivery valve assembly may further comprise a valve body and end cap, which may be joined together, that define a fluid channel. The fluid delivery valve assembly may further comprise sealing elements, a spring element, and an interior stem disposed at least in part in the fluid channel to open and close the fluid channel.

A fluid delivery system for delivering a fluid from an automatic water source to animals housed in cages in high density caging systems may comprise a flexible, non-metal, hose-type manifold line having a plurality of circular apertures and a plurality of injection molded plastic saddle fittings each configured to fit into an aperture. Each cage location may comprise two apertures opposite one other and two saddle fittings fit thereto. The saddle fittings may further comprise a U-shaped portion configured to fit around the flexible manifold line, an inward-facing protrusion sized and configured to penetrate and seal to an aperture, and one or more ribs to seal the aperture and/or grip the flexible manifold.

Apparatus and methods for treating air from a working space 22 that lies above a work surface 20 and in front of a user 8 of the working space. Air is drawn through an air inlet 28 into a fan/filter unit 26, the air inlet in use being located on an opposite side of the work surface from the user and drawing air from the working space above the work surface and at least partly from below the level of the user's face. Air after passing through the fan/filter unit is expelled through an air outlet 30 outside the working space. Additionally a workstation 498 incorporating the apparatus.

Disclosed is an air filtration system comprising a furniture item which may be a table; and at least one air filtration unit configured to integrate with the furniture item. In embodiments, the air filtration system includes at least one integrated receptacle configured to receive the air filtration unit and air channels in fluid communication with the receptacle, wherein the air channels are configured to channel filtered air from the air filtration unit.

The invention relates to a workspace wall (1) for placement on a desk to reduce noise within a noise reduction area (7) in an operating orientation (11). The workspace wall (1) comprises a main wall element (3), at least one wing panel (4), optionally at least one sound detection element (21) for detecting a sound signal input (12), and at least one sound generating device (22), preferably for active noise reduction and/or a passive noise reduction element (20). The at least one sound generating device (22) and/or the passive noise reduction element (20) is configured to reduce the level of noise within the noise reduction area (7). (FIG. 3)

A removable support base is provided that includes interchangeable decorative disks. In one example, a desk fan is provided that includes a fan supported by a support post that is positioned on the top of the removable support base. The removable support base has an upper plate and lower support member that are removably attached to the support post. The upper plate member is separable from the lower support member when detached from the support post. The desk fan further includes a first interchangeable substrate or decorative disk positioned between the upper plate and lower support member. The desk fan further including additional interchangeable decorative disks for interchanging with the first interchangeable decorative disk.
