Usable in an application with a large vertical separation
of up to 90 meters
Y-Series EP Y-Series P R2-Series
A height difference of up to 90m from the
outdoor unit to the indoor unit can be
supported with no extra-cost options.
This increases design flexibility and facilitates
installation of these units even in high-rise
buildings.
Key Components of YNW-Series
Four-way suction and new fan
Y-Series EP Y-Series P R2-Series
• Air suction structure
Previous model (YLM)
Visualization of air flow of fan
Previous three-sided coil design caused fan airflow
turbulence.
• Fan structure

Air flow
The concave-shaped blade of the propeller fan enables air to flow along the outer circumference of the blade while reducing a
disturbance of air flow that occurs in the upstream and downstream of conventional propeller fans. This helps reduce power
consumption as well as minimises sound levels.
Furthermore, the change of the orientation of the fan blade from the outer circumference direction to the inner circumference
direction reduces air leakage from the outer circumference and sends more air to the upstream of the fan.

Height difference from outdoor unit to
indoor unit:
The system can be configured with a
height difference of up to
no extra-cost options.
* Whether the system can be configured with such a
height difference varies depending on the model.
* The maximum height difference is 60 m when the
outdoor unit is located lower than the indoor unit.
* Requires switch settings.
