Midea Breezeless 360º 5x1 Cassette Air Conditioner 2.5 kW (3) + 3.5 kW (2)

The Midea Breezeless 360º 5x1 cassette air conditioner is designed to cool or heat five independent rooms using a single outdoor unit. Each cassette with Breezeless 360° panel distributes air peripherally and evenly, eliminating direct drafts and ensuring a consistent temperature. Its 600×600 mm format integrates perfectly into suspended ceilings, combining aesthetics, A++ efficiency, and ultra-quiet operation—ideal for homes, offices, and commercial spaces.
