摘要： Embodiments of a door assembly with a door component that can open and close in response to pressure of fluids that flow in a fluid handling system. These embodiments utilize elements to seat and lock the door in position without the need for manual intervention and/or interaction, e.g., by a technician and/or maintenance personnel. However, these elements do not need to support the weight of the door and, thus, provide a more robust and cost effective design to achieve automated and reliable operation necessary for use in fluid handling systems.

摘要： A filter arrangement for a system within which fluid is filtered and an associated method of providing the arrangement. A frame of the arrangement includes an outer periphery shape that is complementary to a shape for location of the filter arrangement therein and a plurality of filter cartridge seat slots arranged in V-shaped pairs. Each filter cartridge seat slot provides a sub-aperture for removably receiving a respective filter cartridge in a direction transverse to the flow proceeding through the sub-aperture. The filter arrangement includes a plurality of filter cartridges that are removably located within respective filter cartridge seat slots. The filter arrangement includes a non-permanent sealing arrangement between the filter cartridges and the frame so that flow does not by-pass filter media. The non-permanent arrangement permits removal of the filter cartridges from the frame and replacement with new filter cartridges upon the frame.

摘要： A membrane comprises a sheet of expanded polytetrafluoroethylene. The sheet includes a first extrudate made from a first PTFE fine powder resin mixed with processing lubricant at a first lube rate. A second extrudate is made from the first PTFE fine powder resin mixed with processing lubricant at the first lube rate. The first and second extrudates combined into an integrated tape structure that is stretched in first and second directions. The sheet is porous and has a gas permeability of at least 0.1 CFM according to ASTM D737. The sheet has an average Mullen Hydrostatic Burst pressure in the range of 135 psi to 175 psi according to ASTM D751.

摘要： A cartridge filter insert includes a body, an internal opening, and an exterior surface. The internal opening is configured to permit an airflow through the body. The exterior surface is configured to removably engage a surface of a cartridge filter having an outlet. The internal opening has an inside dimension smaller than an inside dimension of the outlet of the cartridge filter to effectively reduce the inside dimension of the outlet. An inlet filter house including the cartridge filter and the cartridge filter insert are also provided. Methods of filtering a fluid using the cartridge filter and the cartridge filter insert within the inlet filter house are also provided.
