A GAME CHANGER
Fujitsu is proud to introduce the newest addition to our single-zone mini-split lineup – three new Medium Static Pressure Duct
indoor units! These units use the same energy efficient inverter technology you expect from Fujitsu mini-split products, and they
have enough static pressure to heat or cool a whole house. SEER ratings up to 21.3 and a compact size mean these indoor units
can find a place in many applications.

SLIM & COMPACT DESIGN INDOOR UNIT &
OUTDOOR UNIT
New ducted air conditioners
are slim and compact in
design in order to fit into most
ceiling spaces, making them
ideal for hidden installations.
The compact outdoor units can
be installed below a window
and in a narrow space.
