Midea Breezeless 360º 4x1 Cassette Air Conditioner 2.5 kW (2) + 3.5 kW (2)

The Midea Breezeless 360º 4x1 Cassette Air Conditioner is designed to provide maximum comfort in four separate rooms using a single outdoor unit. Each cassette disperses air evenly thanks to Breezeless 360° technology, which distributes airflow from the entire perimeter, eliminating direct drafts and creating a uniform, quiet environment. Its 600×600 mm design integrates easily into modular ceilings, making it ideal for homes, offices, or high-comfort commercial spaces.
