FVXS Series
3-D Airflow CTXG, CTXS, FTXS Series
Alternative repetition of vertical and horizontal swing motions enables uniform air-conditioning of
the entire room.
When the horizontal swing and vertical swing are both set to automatic operation, the airflow
becomes 3-D airflow. The horizontal and vertical swing motions are alternated and the airflow
direction changes in the order shown in the following diagram.
(1) The louvers move from the right to the left.
(2) The flaps move downward.
(3) The louvers move from the left to the right.
(4) The flaps move upward.

Operation
CTXG, CTXS-L, FTXS-L Series
The horizontal blades (louvers) are controlled not to blow the air directly at the people in the room.
The airflow will be in the upward direction while in cooling operation and in the downward direction
while in heating operation, which will provide a comfortable wind that will not come in direct contact
with people.
