More Information
Summary:A filter-valve assembly for exhausting fumes from a liquid container includes a mounting-valve assembly having a valve poppet that is moved to an open position in response to a filter-cartridge assembly being attached to a valve-assembly housing by a filter-cartridge attaching mechanism and is moved to a closed position in response to the filter-cartridge assembly being detached from the valve housing. The filter-cartridge assembly includes a coalescing filter and a carbon filter, with an orientation-activated capsize valve located in a coalescing-filter housing for preventing spills upon capsizing and litmus-like material at an exit opening of a carbon-filter housing for indicating a need to replace the carbon filter.
