The Daikin FXSQ-A internal channel units are reliable, highly efficient, hidden type air conditioners that are used in the third and fourth generation VRV systems. Air conditioners of the hidden type are most popular, since they are installed under a false ceiling or false wall in such a way that only the air intake grid is visible from the outside.

In addition, one unit can provide cooling of air immediately in two rooms of a small area when distributing ducts accordingly. The indoor unit is installed in the hallway or corridor, and air ducts are directed into the rooms.

VRV-systems of the fourth generation can significantly save electricity at maximum loads, as well as with regular use at medium revs. The indoor unit is also designed to maximize resource savings - the unit has improved aerodynamic performance, as well as many other indicators. The unit has a filter against dust, pet hair, field mites, saprophytes and many other impurities up to 0.3 microns in size.
