Due to optimization of outlet design of air flow with our
new advanced technology, sufficient air flow is secured
and long reach of air flow is realized. (FDT)
For person who is far
from the indoor unit
For both persons who are
feeling hot or cold
Can cool both the kitchen
and the guests
Expansion of outlet air flow area realizes
reduction of pressure loss caused by air flow
in the indoor unit. Load of fan motor is
decreased and efficiency is increased.
• Reduction of air flow pressure loss

• Increase of heat transfer efficiency
Applying high efficient piping in heat exchanger and
optimization of heat exchanger (2parts 1part)
increases heat transfer efficiency.
Individual flap control system
According to room temperature conditions, four
directions of air flow can be controlled individually by
following Flap control system.
As individual flap control is available even after
installation, installation area became wider than before.
The thinnest design
Thanks to new design of heat exchanger changed from 2 parts to 1 part, the height of
indoor unit is reduced drastically.

Flap control system
The flap can swing within the range of upper and
lower flap position selected with wired remote control.
(this system is applied for FDEN, SRK type also)

Wireless remote control and RCH-E3 is not applicable to the Individual flap
control system and the Flap control system.

You can set External Static Pressure (E.S.P.) by method
of manual setting on remote control. Indoor unit will
control fan-speed to keep rated air
flow volume at each fan speed setting.
You can set required E.S.P. by wired
remote control that calculated with the
set air flow rate and pressure loss of
the duct connected.
Dirt condition of the bottom of a drain pan can be
checked through this transparent inspection
window without removing drain pan.
