LG Round Cassette Air Conditioners outperform competing products in both design and performance. Traditional round cassette indoor units include 3 separate air outlets that disperse air in 3 directions, resulting in blind spots. But LG's new round cassette air conditioners reduce the circular vent connections to distribute airflow all around, completely eliminating blind spots. Users can also take advantage of crystal panels for precise six-stage control to distribute cool or warm air anywhere needed. This shape features double the airflow control accuracy of the three-stage airflow provided by other round cassette air conditioners. LG has conducted extensive air chamber tests to ensure the precise round airflow control can achieve 30% faster cooling compared to other round cassette air conditioners available on the market. Even with this exceptional performance, the operating noise level emitted by LG Round Cassette Air Conditioners does not exceed 39 decibels (A), which is lower than the typical library noise level of 40 decibels (A). These features contribute to making LG Round Cassette Air Conditioners suitable for all customer environments.
