  • Bidirectional filter drier
    Patent number: 11391498
    Abstract: A bidirectional filter drier has a generally spherical outer shell having a first opening and a second opening. The shell contains a desiccant core and first and second filter elements. The first filter element is on a first side of the core, adjacent the first opening, and the filter flexible element on a second side of the core adjacent the second opening. The first filter element and the second filter element control flow around and through the core depending on the direction of fluid flow through the filter drier.
    Type: Grant

  • Filter drier
    Patent number: 9951980
    Abstract: A spherical filter drier for an HVACR system includes a generally spherical shell and a core that is fixed position relative to the shell. The shell has a first opening and a second opening in fluid communication with one another across the core. The core includes a media that removes contaminants from fluid flowing from the first opening through the core to the second opening. The spherical shell may be a monolithic shell, or formed from a pair of generally hemispherical shells.
