Extremely Quiet Operation and Elegant Design Matching Any Interior Industry-leading Low Sound Pressure Level Highly-advanced low sound pressure level, 30 dB (A) (P28 to P56: at HIGH speed operation) is realized by adopting the new DC fan motor and the vibration-proof structure which protects the turbo fan from abnormal sound. The low sound pressure level is 2 dB lower than the conventinal units and further quiet operation is achieved.

Quiet Operation and Low Height Design for Limited Space Inside of the Ceiling Broader range of external static pressure. Flexibly supports a wide range of installation conditions at site, e.g. longer ducts. In addition to the standard Hi-Me-Lo, the speed-up tap can be set by remote control. Available for external static pressure of up to 80 Pa for P22 to P71 and 170 Pa for P90 to P140. Space-saving Design Less than 270 mm in height, this unit can be fit into practically any previously existing false ceiling or formerly ducted space without substantial modification (P22 to P71).

Quiet Operation, Easy Installation and Space-Saving Slim Design Amenity improved by auto-louver at air opening. The round, lower part of the air opening complements the gentle, quiet operation. The auto-louver in the upper part of the opening automatically controls upward and downward motion of airflow, while the grille serves as a shutter when stopped. Noise and vibration drastically reduced by the original design. The large fan and improved resistance of the airflow path lower the r.
