What is an Air Fan Exchanger Header?
An air fan exchanger header, sometimes referred to as a fan coil header or simply a header, is essentially a distribution manifold. It acts as a central hub connecting the main air supply and return ducts to multiple individual fan coil units (FCUs). These FCUs are responsible for conditioning the air in specific zones or rooms within a building.
How Does an Air Fan Exchanger Header Work?
The header receives conditioned air (either heated or cooled) from the central air handling unit (AHU) through the supply duct. This air is then distributed to the connected FCUs via a series of internal pathways and branches within the header.
On the return side, the header collects the air from each FCU after it has circulated through the designated space. This air, which may have been heated or cooled by the FCU, is then channeled back to the AHU through the return duct for further conditioning.

Types of Air Fan Exchanger Headers
Air fan exchanger headers are available in various configurations to accommodate different system designs and requirements. Some common types include:
- Single-Zone Headers: These headers serve a single zone or area with multiple FCUs operating at the same temperature setpoint.
- Multi-Zone Headers: These headers can supply air to multiple zones, each with its own temperature control, allowing for customized comfort levels in different areas.
- Vertical Headers: As the name suggests, these headers are installed vertically, often within wall cavities or chases, making them suitable for applications with limited ceiling space.
- Horizontal Headers: These headers are installed horizontally, typically above ceilings or in mechanical rooms.
The choice of header type depends on factors like the building layout, the number of zones requiring conditioning, and available installation space.
Benefits of Using Air Fan Exchanger Headers
Incorporating air fan exchanger headers into HVAC designs offers several advantages:
- Improved Air Distribution: Headers ensure a more balanced and even distribution of conditioned air to all connected FCUs, minimizing temperature variations and enhancing occupant comfort.
- Increased System Efficiency: By optimizing airflow, headers can reduce the workload on the AHU, potentially lowering energy consumption and operating costs.
- Simplified Installation and Maintenance: Headers streamline the installation process by providing a central connection point for multiple FCUs. They also simplify maintenance tasks like cleaning and filter replacement.
- Enhanced Design Flexibility: Headers offer greater flexibility in system design, allowing for easy expansion or modification of the HVAC system in the future.
Common Applications of Air Fan Exchanger Headers
Air fan exchanger headers find widespread use in a variety of commercial and industrial settings, including:
- Office Buildings: Providing customized temperature control for different offices or work areas.
- Hotels: Ensuring consistent comfort levels in individual guest rooms.
- Hospitals: Maintaining precise temperature and humidity control in critical care units or operating rooms.
- Schools: Creating comfortable learning environments in classrooms and other areas.
