External Static Pressure(E.S.P) control
You can set External Static Pressure (E.S.P.) bymethod of manual setting on remote control.Indoor unit will control fan-speed to keep rated airflow 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.
Quiet operation:45dB(A)
Thanks to use of DC fan motor, fan steps increase from two to four and quiet operation is achieved. (Sound pressure level 45dB(A) in the Lo mode).
Improvement of the serviceability
Fan unit (impeller and motor) can be pulled out from the right side of the unit. Maintenance can be available from the right side or the bottom side. (Common for FDUM22~160KXE6F & FDU45~160KXE6F)

Specifications
1. The data are measured under the following conditions(ISO-T1). Cooling: Indoor temp. of 27ºCDB, 19ºCWB, and outdoor temp. of 35ºCDB. Heating: Indoor temp. of 20ºCDB, and outdoor temp. of 7ºCDB, 6ºCWB. External static pressure of indoor unit is 60Pa.
2. Sound pressure level indicates the value in an anechoic chamber. During operation these values are somewhat higher due to ambient conditions.
*Powerful-Hi can be selected. Sound pressure level: FDU45/56 37dB(A), FDU71/90 38dB(A), FDU112 44dB(A), FDU140 45dB(A),FDU160 47dB(A). Air flow: FDU45/56 13m3/min, FDU71/90 24m3/min, FDU112 36m3/min, FDU140 39m3/min, FDU160 48m3/min.
