Each of the four vanes in the 2-way cassette unit can be controlled independently using separate motors. This allows for precise airflow direction in six different steps.

1 WAY CASSETTE:

The installation environment does not affect the 1-way cassette. The 1 Way Cassette is the ideal choice for installation in a compact space due to its 190mm duct size and 132mm height. Simple maintenance is ensured with washable filters. LED indicator with 6 colors is provided that shows the AQI Air Quality Index.

2. Concealed Duct Units:

LG VRF systems offer two duct options for tailored airflow management:

Low Static Duct (LSD):

Perfect for most applications LSD has an easy-to-use remote control that allows for accurate airflow adjustment. Its BLDC motor does not require additional control equipment since it automatically maintains the desired airflow even in the presence of pressure fluctuations. With rear or bottom air intake and the potential for multi-zone comfort with appropriate accessories, LSD offers versatile installation.

High Static:

LG provides High Static Ducts for large ductwork or high-resistance buildings (HSD). For intricate layouts, HSD provides strong airflow, guaranteeing effective temperature management. HSD is still a good choice for standard needs and is flexible enough for a wide range of tasks.

3. Floor-Standing Unit:

Sleek Design: This goes well with many different types of interior decor.

Strong Performance: Effectively heats and cools big areas.

Comfort with a Long Range: Provides powerful airflow for efficient temperature adjustment up to 15 meters away.

4. Ceiling & Floor Units:
