1. An air diffuser for a heating, ventilation, and/or air conditioning (HVAC) system, comprising:
a variable flow adapter including a housing;
a first plurality of nozzles disposed in the housing and defining a first set of flow paths from an interior of the housing to an exterior of the housing;
a second plurality of nozzles disposed in the housing and defining a second set of flow paths from the interior of the housing to the exterior of the housing;
at least one actuatable device configured to be transitioned, based on an air flow parameter in the housing, between actuation states to control air flow through the second set of flow paths of the second plurality of nozzles; and
a barrier in which the at least one actuatable device is disposed, wherein:
the barrier separates a first chamber in the interior of the housing from a second chamber in the interior of the housing, wherein the second is downstream from the first chamber;
the first plurality of nozzles is fluidly coupled with the first chamber; and
the second plurality of nozzles is fluidly coupled with the second chamber.
