Toshiba DAISEIKAI 10 Wall Mounted Air Conditioner (Single Split, R32)
The Toshiba DAISEIKAI 10 is a premium single split wall-mounted air conditioner and heat pump designed for top-end efficiency, comfort and indoor air quality. It uses R32 refrigerant, includes built-in WiFi, and features one of the quietest and most refined indoor units in Toshiba’s line-up.
This model is available in two fascia finishes to suit different interior styles:
-
White fascia – clean, modern and minimal, ideal for contemporary interiors.
-
Wood-effect fascia – a premium textured finish designed to blend into natural, rustic or Scandinavian-style rooms.
Both versions share the same internal technology, performance levels, airflow pattern and casing dimensions – the fascia is the only aesthetic difference. This allows you to select the look that suits your room without affecting technical performance.
