The Haier ADnS2SM3FA duct-type split system is a medium-pressure air conditioner that fits perfectly behind a false ceiling. On the air supply side there are two electric drives, to which an additional decorative grille is connected. There are two sets of grilles to choose from: one without a display, the second with a built-in IR sensor and display. Grilles are not included in the kit and must be purchased separately.

Medium-pressure duct air conditioners are best suited for servicing 2–3 adjacent rooms that have one common hall or corridor, where the air conditioner is installed. Basically, such air conditioners have a relatively low noise level, so they are convenient to use in elongated rectangular office premises with an area of 50–150 square meters, and in rooms with a complex configuration.

A pressure of 50–100 pascals or more allows the use of a small network of air ducts 5–15 meters long for both supply and air recirculation. However, if possible, it is recommended to perform general air recirculation through the transfer grilles.

This air conditioner uses R32 refrigerant to operate. It is more economical to use and 68% safer for the environment than its R410A counterpart. The drainage pump is also included as standard, which significantly expands the installation options.
