Abstract: Embodiments of the present invention provide low-profile surface mount filters. One embodiment of the present invention includes a filter housing adapted to mount on a substrate block having a plurality of flow paths and a filter cavity defined therein. The filter cavity is defined to extend in a generally horizontal direction when the low-profile filter is in use. A first flow passage is defined to connect an inlet of the filter housing to a first section of the filter cavity and a second flow passage is defined to connect a second section of the filter cavity to an outlet of the filter housing. A filter assembly is disposed in the filter cavity and sealed to the surface of the filter cavity separating the filter cavity into adjacent sections including the first section of the filter cavity and second section of the filter cavity.

Abstract: The present invention provides a fluid filter utilizing a polymeric membrane supports by metallic screens contained in a housing. The supports have apertures through which fluid can pass. The metallic supports are created such that they have at least one surface substantially free from burrs, so as not to damage the membrane. This smooth surface is in communication with the polymeric membrane. One or more indexing protrusions can be added along the circumference to restrict the relative movement between the supports, and to align the apertures of the two supports.
