ABSTRACT:
A stainless steel filter assembly which filters fluid entering a fluid interactive device, such as a gas analyzer, includes a connection block in the line which has lateral ports for coupling with an inlet coupling and an outlet coupling on a filter. The filter has a folded filter media made of sintered stainless steel panels which are separated by stainless steel screens that increase the surface area of the filter media exposed to the inlet stream of fluid to be filtered.
