Daikin FFA18AVJU9 Ceiling Cassette 1.5 Ton R-32

Product Description

The DAIKIN FFA18AVJU9 is a 1.5-ton ceiling cassette indoor unit designed for ductless mini-split and multi-zone systems using R-32 refrigerant. Part of the FFA series, this unit mounts flush into a 2x2 ceiling grid, delivering conditioned air in a compact, low-profile form factor suited for commercial and residential spaces where floor or wall-mount units are not practical. Licensed HVAC technicians install this unit as part of a complete system pairing with a compatible outdoor condensing unit. The R-32 refrigerant circuit offers a lower global warming potential compared to R-410A, meeting current environmental standards for new installations.

The FFA18AVJU9 is suited for light commercial and residential ceiling applications, including offices, hotel rooms, retail spaces, and open-plan areas where a discreet ceiling-mount delivery is preferred. According to the supplier, this unit can be matched to a compatible Vista outdoor unit or a compatible multi-head outdoor unit, making it viable in both dedicated single-zone and multi-zone configurations. Installation is ceiling-mounted, typically in a standard 2x2 drop-ceiling grid opening.
