A blower or fan used for distributing supply air is referred to as an air-handling unit. This component is essential in HVAC systems, as it is responsible for moving air throughout the system and into various spaces in a building. The air-handling unit can also play a role in conditioning the air by incorporating filters, coils for heating or cooling, and controls for ventilation.

Air-handling units are designed to optimize airflow and ensure efficient distribution of conditioned air, which directly impacts the comfort and air quality within a space. They often include various components, such as blowers or fans, which facilitate air movement, and are integral to the overall function of an HVAC system.

Other choices refer to components or systems that do not specifically characterize the function of air distribution. For example, an absorption system refers to a type of refrigeration system, while a portable cooling unit describes a specific type of air conditioning equipment that can be moved to different locations. HVAC appliance is a broader category that encompasses multiple devices within the HVAC system but does not specifically denote the equipment responsible for air distribution like the air-handling unit does.
