Highly Flexible Installation and Design
3-Way Cooling and Heating FSV-EX MF3 Series
The FSV-EX MF3 Series has superior installation capability and can be installed in a variety of arrangements.
This flexibility is advantageous not just during installation but also in terms of maintenance and repairs.
Increased Piping Length for Greater Design Flexibility
Adaptable to various building types and sizes
Actual piping length: 200 m
Maximum piping length: 500 m
*40 m if the outdoor unit is below the indoor unit.

High External Static Pressure Allows Installation on Every Floor of a Building
With a newly designed fan, fan guard, motor, and casing, new models can be custom-installed on site to provide up to 80 Pa of external static pressure. An air discharge duct prevents shortages of air circulation, allowing the installation of outdoor units on every floor suitable for high-rise buildings.
