The hospital relies heavily on indoor hygiene and comfortable wards to ensure the rapid recovery of patients. Therefore, the hospital is very demanding in terms of hygiene. Air curtains in hospitals need to prevent harmful gases, such as outdoor dust, debris, and automobile exhaust from entering. Similarly, our air curtain can prevent hot and cold air from entering the outpatient hall, thereby increasing high electricity costs and affecting the health and comfort of patients. Therefore, you can see the air curtains at the front door, back door, and side door of the hospital. They are playing a very important role in maintaining the sanitation of the hospital and providing a comfortable environment.
