The air-tight door is a sliding door set that integrates air-tightness, sound insulation, thermal insulation, pressure resistance, dust prevention, fire resistance, and radiation protection. It is generally used in places with high requirements for sound insulation, thermal insulation, and air-tightness, such as hospitals, food factories, and industrial plants. The air-tight door uses a small-sized, high-power DC brushless motor. Even with frequent opening and closing, it can operate for a long time without failure. Professional vacuum sealing strips are installed around the door, using a unique pressing technology to ensure that the door fits tightly with the door frame when closed, achieving reliable air-tightness. The air-tight door is equipped with a foot control switch and a dedicated handle, making it convenient for medical staff to open the door. In case of a power outage, the dedicated handle can be used to open the door with very little push or pull force.

　　The air-tight door can be equipped with sensors, which not only effectively prevent people from being pinched but can also be set to automatically open the door from the room when the sensor is triggered; it can be controlled by a remote control, making it simple and convenient. Users can set the sensor's action effects according to their needs and flexibly adjust the sensor's action mode based on the doctor's working habits and the characteristics of various operations to achieve good results.

　　Functions of the air-tight door:

　　1. The opening and closing of the air-tight door are mechanized and automated, with reliable operation. The door's opening and closing are driven by a motor, significantly reducing the labor intensity and improving the efficiency of the entrance and exit doors. With advanced control technology and protective measures, automatic entrance and exit doors are more reliable.

　　2. The sealing performance and energy-saving performance of the air-tight door. Regardless of the position it is turned to, the air-tight door will automatically move closer to the outside and inside of the door, which can reduce heat loss, minimize dust intrusion, enhance sealing, and save energy. Other types of air-tight doors can quickly close automatically and adjust the opening width of the door leaf, which also increases their sealing and energy-saving performance.

　　3. The air-tight door enhances the decorative beautification function of the building. Due to the widespread use of new designs, new decorative materials, and new processing techniques, its shape and structure will be more coordinated and matched with the building, enhancing the beautification function of the building.

　　The inflatable air-tight door mainly consists of a door frame, door panel, inflatable sealing strip, and inflation/deflation control system. The inflatable sealing strip is embedded in the groove of the door panel frame. The corners of the door frame and door panel are rounded with a radius greater than 150mm, and the door panel has a sandwich structure with thermal insulation and sound insulation materials in the middle. The two side panels are firmly combined with the frame through pressing and board-making technology. The materials of the door frame and door panel are 304 or 316L stainless steel. The working principle of the inflatable air-tight door is: when the door is opened, the inflatable sealing strip deflates and contracts in the groove. When closing the door, the inflatable sealing strip inflates, forming a tight seal between the door and the door frame, locking the door securely.
