Installation Considerations

(1)

The ceiling embedded-type: 500 · 1000 and 2000 m

3

/h types are available.

Select an adequate model according to the room size, air volume for the application and noise levels.

(2)

All types have an extra-high notch. This setting is for when a long duct is used or when a large air volume is required.
The positive and negative pressures of the room can also be adjusted with this.

LGH- 50 · 100RX types

LGH- 200RX type

(3)

The units have a low-noise design, however, for further noise reduction a silencer-type supply/return grille for
supply/return air in the room, a silencer box for reducing the air sound into the room, and a flexible silencer are available.
