Functions and extras:











Possible to install in narrow ceilings due to shorter length and slimmer dimensions.
The A7 Duct has a 20% reduction in volume compared to the A6 Duct. The lower and narrower units are much easier to install in tight spaces.


With Auto Airflow Match, A7 Duct can automatically match the airflow volume to different ducting designs, resulting in installation convenience, comfortable experience and cost saving.
The outdoor units for the A7 48K & 55k Btu/h models have been completely redesigned. Easier installation is achieved for this compact and lightweight outdoor unit.


Two types of filters are available for the A7 series duct-type air conditioners:
The indoor noise level of A7 Duct has been dropped by up to 6dB comparing with A6 Duct.
