360º Air Flow 4 Way 90x90 Cassette 

4 Way 90x90 Cassette. Wide & Comfortable Airflow
This proprietary design provides a wide and very comfortable airflow. The cassette’s wide-angle discharge outlets and flaps are larger in the middle, featuring a shape that was selected based on geometrics and testing of actual prototype units. Air coming out of the center of the discharge outlets travels farther. From the sides of each outlet, where the openings are larger, airflow spreads out to reach the corners of the room. Air is discharged across a wide area from the four sides of the unit. The curves on the room temperature distribution graph expand gently out through 360° in a circle centered on the indoor unit.
A: Higher efficiency split fin.
Improved heat-transfer coefficient due to adoption of high efficiently grooved heat exchanger tube. 

B: High-efficient & Silent turbo Fan.
The newly developed larger fan chassis and optimised design of the airflow path has resulted in increased air volume and quieter performance.
C: New DC-Fan motor.
Optimum airflow is achieved by a new DC-fan motor with independent control.

Individual flap control.
Flexible Air flow direction control by individual flap control is possible. 4 Flaps can be controlled individually by setting on wired timer remote controller. It can make more flexible Air-flow control to be matched to several demands in a room.
New 360º Air Flow for improved comfort
The new air-outlet and flaPdesign creates a soft and gentle air flow which circulates throughout the whole space and provides an even temperature distribution in the room.

Flexible 3D air-flow control
Comfort air flow control & proper energy use. Flexible Air flow direction control by individual flap control: 
  • 4 Flaps can be controlled individually (by standard wired remote controller*).
  • Versatile air flow control to cover a wide variety of demands.
A: Outlet A: Swing (only upper)
B: Outlet B: Fix to upper
C: Outlet C: Swing 
D: Outlet D: Fixed to Lower

* Pre-setting is required for this function at System Test-run procedure.
New design
Wide direction air discharge by outlet design.
The Circle Flow Flap and re-designed air-outlet eliminate airflow along recessed parts of the ceiling which reduces contamination. If air flows only along these recessed parts, they will quickly become dirty.
The new, improved air outlet design therefore greatly reduces dirt accumulation.
