A cassette like this one diffuses air in four directions, which allows for better temperature distribution in a square or slightly rectangular room.

In an office, meeting room, or treatment room, poor positioning can create very real discomfort: cold air on the shoulders, drafts on a work table, or heat trapped near the ceiling. With a four-way cassette, we can adjust the air orientation to limit these irritants.\u003c\/p\u003e\n\u003cp data-start=\"3938\" data-end=\"4303\"\u003eThe indoor sound level is also a strong point of the model: \u003cstrong data-start=\"4001\" data-end=\"4023\"\u003e30 \/ 33 \/ 36 dB(A)\u003c\/strong\u003e depending on the speed. In practice, in a quiet room, this helps maintain a pleasant working atmosphere.
