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.
