A fluid cartridge for a printing device includes a housing having a base and a first and second chamber. A wall extends outwardly from and substantially normal to the base and is configured to separate the housing, thereby forming the first and second chambers. An air/ink exchange port is defined in a bottom portion of the wall and adjacent to the base. A longitudinal air flow-restricting member is disposed adjacent the air/ink exchange port and on the base, and extends outwardly predetermined distance into one of the first or second chambers.
