Key Features & Benefits

AEROWINGS Airflow Control

Panasonic’s twin-blade AEROWINGS system helps direct airflow further across the room for more even cooling and heating. This improves comfort by reducing hot and cold spots and delivering conditioned air more effectively.

Anti-Bacterial Air Filter

The built-in anti-bacterial filter is designed to help reduce bacteria, allergens, mould, odours, and airborne particles, improving indoor air quality and creating a cleaner indoor environment.

POWERFUL Mode for Fast Cooling & Heating

POWERFUL Mode runs the compressor and indoor fan at maximum speed to cool or heat the room quickly, making it ideal when you arrive home on a very hot or cold day.

Quiet Operation

The RZ Series is designed for quiet performance, making it suitable for bedrooms, living spaces, and home offices. Indoor sound levels range from approximately 28dBA to 44dBA depending on the fan setting.
