Totally new appearance design
AB05-18 adopt the 700*700 panel with
660*570 unit body. And AB18-48 use the
same panel, more easy installation and
design. Compact and unitary appearance
to get perfect harmonized indoor
decoration.

Built-in high head drainage
A Standard built-in drain pump can realize up to Max. 600mm drainage head, which creates the ideal solution for
perfect water drainage.
Fresh air inlet
Pre-set fresh air inlet hole, which can lead the fresh air from outside into indoor, greatly improves indoor air quality.
Long life lter is standard part with the unit.
