1. The advanced four-cylinder compressor ensures smooth operation and significantly reduces equipment noise at its source. (The noise inside the cabin is ≤ 50 decibels during operation.) The external oxygen generation unit and air conditioning system have undergone deep noise reduction treatment to ensure a quiet operation process.

2. The vehicle-grade carbon steel structure effectively resists pressure changes during the compression and expansion process, ensuring that the cabin body does not deform or make abnormal sounds. The steel plates are precisely processed by a fully automatic digital machine to ensure the extremely high precision and strength of the cabin structure, without the need for glue-assisted closure.

3. Equipped with an advanced three-level filtration system, it effectively filters out viruses, bacteria and other pollutants in the air; the efficient filtration combined with the intelligent air exchange mode inside the cabin ensures fresh air inside, preventing drowsiness from prolonged sitting and eliminating unpleasant odors.

4. The built-in patented technology and medical device-grade negative oxygen ion module further purify the air, creating a forest-like fresh atmosphere, helping to relax the body and mind, and enhancing the overall health care effect.
