  • Publication number: 20140273798
    Abstract: 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.

  • Publication number: 20140182254
    Abstract: This disclosure proposes a new structure for pre-filter devices, and filtration systems in general, that facilitates tasks necessary to maintain performance of pre-filter banks in the filtration system. Embodiments of this structure allow the pre-filter devices to translate on corresponding structural members that make up the supporting structure of the pre-filter bank. When in position, the proposed pre-filter devices can mate with adjacent pre-filter devices to form a substantially unitary structure that prohibits fluid from flowing unfiltered to areas downstream of the filtration system.
