Fresh air inverter split system

ZTF1I2

Temperature control and a dedicated fresh-air path, composed as one wall-mounted system.

01 / Fresh-air path

A second route for the air you breathe.

The liftable top inlet creates a dedicated path for outdoor air while the indoor unit continues to manage room temperature. A blue light detail makes the inlet visible at a glance.

02 / Filtration

Four layers.
One readable sequence.

Each stage has a defined place in the fresh-air route. The diagram keeps the layers separate instead of hiding them inside a generic filter claim.

03 / Air status

Air quality, shown on the unit.

Integrated TVOC sensing feeds the circular status display. The filter-life reminder appears when remaining life falls below 20%, making routine attention visible without adding another panel to the room.

04 / Gentle Breeze

1,222 micro-holes divide the outlet flow.

The louvre disperses the supply stream across a dense perforated surface before air enters the room, supporting a softer distribution pattern.
