Patent
Advanced Technology Materials Incorporated and Entegris | Date: 2012-12-06

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.
