3 L coil designLanced fin designAir return grille and filter The filter inside the air return grille can be easily removed and washed, And keeps the room air fresh through constant circulation. The front panel and frill of the unit are designed with stylish appearance makes it suitable to match various room is a compact unit only 298mm in height. The four suspension brackets of the unit adopt the T shape opening, it can be installed up and fixed air distribution gives individual comfort while for localized control each diffuser may be adjusted or even shut down unique design of centrifugal fan ensures the quiet running of the unit.

4 This thoroughly eliminates the bothering throttle noise inside the condensate drain pump encased in a special sound-insulating material removes condensate quietly and air enters the cassette unit through a large grille, cleaned by an easily removable, washable filter, and then keep the room air fresh through constant circulation. The Special design of the diffuser ensures rapid blending of the supply and room air. Conditioned air is directed along the ceiling then evenly distributed throughout the Large LCD screen thermostat is drain pumpHigh performance condensate drain pump inbuilt the unit, and enwrapped with special designed insulation out the condensate water running when the unit avoid the leakage of the condensate water.
