Features: 1, DC motors, DC energy saving plastic cassette fan coil brushless DC motors, compared to the same general type of machine saving up to 55%, more cost-effective; the fan is running high gear than normal AC motor running saving 50%, saving 65% intermediate speed, more than 75% energy saving low profile; using plastic structure, the body's moisture dust is not easy to enter the internal motor, high motor efficiency, temperature rise is small, the internal components of aging slow, long service life. 2, the air even more air to flow to make the temperature more uniform application areas 3, ultra-quiet operation using advanced three-dimensional design, streamlined large-diameter turbine centrifugal fan, high efficiency air flow, air volume, low noise, because the fan hub partially processed into sine seam, improve flexibility fan, so that the vibration of a substantial decline in fan operation, but also reduces motor noise generated due to the swing 4, high lift pump designed to enhance high-lift pump design 750MM, condensate pipe layout more flexible, water level switch protection, to prevent leakage risks 5, introduction of new wind of fresh air to improve indoor environment suction respirable outdoor part of the new negative, to ensure indoor air quality, allowing users to enjoy the fresh clean air, reducing air conditioning disease. 6. Installation is simple slim slim body thickness of the thinnest public 290MM, when compared to the horizontal fan coil without requiring separate installations, the outlet, and without cumbersome air duct and insulation work 7 structure designed to facilitate convenient machine maintenance Remove air intake grid, you can remove the electrical box wind circle, because the fan diameter of less than foam wind circle, you can directly take out the fan and motor, the unit standard dimensions can be easily installed in a standard ceiling opening, square panel, you can select the direction of the unit connecting pipe installed according to the actual situation, optional stainless steel hose connection for easy installation
