FILTER ASSEMBLY WITH SPIN-ON FILTERS AND METHODS USING THE FILTER ASSEMBLY

摘要

A filter assembly including a filter head and two filter elements operably connected in parallel to the filter head for filtering fluid such as natural gas and other fuel gases. The filter assembly includes a filtering material for removal of sulfur compounds from the fluid being filtered; a first filtering material can be used for the removal of mercaptans and a second filtering material can be used for the removal of other sulfur compounds. The filter assembly includes various seals to inhibit leaking of liquid, specifically filtered liquid, from the connection of the filter elements to the filter head. The filter assembly is particularly useful for use in fuel cell systems.
