2 Floor Standing Type MVF-A-VA1 MVB-A-VA1
1. Feature
1.1 Exposed & Concealed type
Air intake from front (F4 series) Air intake from below (F5 series)
1.2 Lower noise
Flat shape air outlet, three speeds adjustment. Smoother airflow with less turbulence.
Adoption of the built-in Fujikoki brand electronical expansion valve, ensures precise flow control, as well as
lower modulation noise when EXV operating.
1.3 Easy Installation
Floor standing types can be hung on the wall or installed on the floor. The former can make cleaning and
maintenance much more easily. Running the piping from the back allows the unit to be hung on walls.
Cleaning under the unit, where dust tends to accumulate, is considerably easier.
1.4 Easy maintenance
Filter is equipped as standard accessory; and it can be removed and cleaned easily due to Midea’s
sophisticated design as well as the removable blades.
Streamlined appearance makes it much more harmonious with the decoration. All metal parts are made of
commercial grade galvanized steel, providing maximum protection against corrosion.
1.5 Auto restart
When the indoor unit is powered off, it will auto restart when powered on again after 3 minutes and operate in
the original state.
