Fujitsu ADUH09KUAS – 9,000 BTU R‑32 Slim‑Duct Mini‑Split Indoor Unit

Experience discreet, energy-efficient comfort with the Fujitsu ADUH09KUAS, a slim-duct indoor unit designed for multi-zone ductless systems. Ideal for residential and light-commercial spaces up to ~350 sq ft.

Sleek, Low-Profile Installation

With dimensions of approximately 7-13/16″ H × 27-9/16″ W × 24-7/16″ D, the ADUH09KUAS is designed for concealed installation in ceilings, closets, or soffits—maintaining a clean look while delivering effective airflow with minimal visual impact.

Quiet, High-Performance Operation

Powered by advanced inverter technology and using eco-friendly R‑32 refrigerant, this unit delivers efficient heating and cooling with ultra-quiet sound levels as low as 24 dB(A). Multiple fan speed settings (Auto, High, Med, Low, Quiet) ensure customizable comfort and energy savings.

Indoor Air Quality & Drainage

A washable air filter captures dust and particulates, while a built-in drain pump simplifies condensate removal and allows for flexible installation, even in tight or elevated spaces. Internal anti-corrosion measures help preserve coil integrity over time.

Smart Multi-Zone Compatibility

The ADUH09KUAS is designed for use with Fujitsu’s R‑32 multi-zone outdoor units. Control options include wired and wireless remotes, third-party smart integration, and optional Wi‑Fi adapters for app-based control via Fujitsu’s FGLair or AIRSTAGE Mobile platforms.

Durable, All-Season Ready

While indoor units don’t directly determine low-ambient heating, the ADUH09KUAS supports full-season performance when paired with Fujitsu’s XLTH (Extra Low Temp Heating) outdoor units, capable of operating down to –15°F. Includes hot-start and auto-defrost functions for consistent comfort.

Ideal for Hidden Comfort

Perfect for bedrooms, home offices, hallways, or light commercial zones where discreet, ducted climate control is preferred, the ADUH09KUAS delivers reliable, quiet, and flexible comfort without sacrificing space or style.
