Abstract: A filtration element including a cylindrical housing enclosing a fluid filtration media extending along an axis (X) between opposing ends with a first and second end cap located at each end, wherein each end cap includes: i) an annular surface co-extensive with the housing, and ii) outer face laying in a plane perpendicular with the axis (X). The outer face of at least one end cap comprises an annular groove. A face seal including a base is located within the annular groove. A flexible lip extends axially from the base and axially beyond the outer face of the end cap and is adapted to engage with an abutting outer face of an end cap of an adjacently positioned filtration element.

Abstract: A water treatment dispensing apparatus has a container for holding water from a water supply and a water disinfectant cartridge located within the container. A housing attached to the container and connected to the cartridge directs water from the cartridge to a remote location, such as a dental instrument. An air pressure device supplies water under pressure to the container to force water to flow through the cartridge and to the remote location.

Abstract: No-filter no-run filtration systems are described. The filtration systems include a valve positioned within a filter housing. The valve is normally biased in a closed position when a filter cartridge is not inserted into the filter housing such that from within the filter housing cannot flow to an internal combustion engine. The filter cartridge includes a main filter element and a hydrophobic screen assembly. The hydrophobic screen assembly includes a valve interaction pin that interacts with and opens the valve when the hydrophobic screen assembly is received in the filter housing in an operating position. Accordingly, fuel can only flow from the filter housing to the fuel injectors when the hydrophobic screen is received within the housing in an operating position. The hydrophobic screen is a separate component from the main filter element allowing for independent replacement of the main filter element and the hydrophobic screen.
