Daikin FTA18AAVJUA 18K BTU SkyAir Mini Split Air Handler Multi Position Single Zone R32

Product: FTA18AAVJUA 

Descriptions: 

The Daikin FTA18AAVJUA is an 18,000 BTU R‑32 refrigerant indoor air handler designed for use in single‑zone SkyAir ductless HVAC systems. It is a multi‑position air handler, meaning it can be installed in upflow, downflow, horizontal right, or horizontal left orientations depending on the duct layout and installation needs. This flexibility makes it suitable for both new construction and retrofit projects.

The unit is built for residential or light commercial applications that require a powerful indoor air handler to work with a matched outdoor condenser (heat pump) to provide year‑round cooling and heating. It features an all‑aluminum coil for improved durability and heat transfer, is engineered for minimal air leakage to maintain efficiency, supports higher external static pressure for ducted installations, and includes factory‑integrated refrigerant leak detection for increased system safety. The unit does not include a remote control by default and typically uses a separate wired or wireless controller for operation.
