Automatic air-tight door for operating rooms
It employs an AC variable-frequency motor as its core drive unit and can be configured for either single-leaf or double-leaf operation. The drive track beam is made of aluminum alloy profiles and features two unique, advanced patented designs. Through the cooperation between the guide rollers and corresponding grooves on the guide rails, as well as the groove at the bottom of the movable door and the small cylindrical components, when the movable door leaf closes and moves into the groove, the control mechanism leverages the door’s own weight to firmly press the rubber strips around the door’s perimeter and sides, along with the flat rubber pad at the bottom, ensuring tight contact between the door and both the door frame and the floor. This design guarantees the airtightness requirements of the door and results in a structurally sound and highly reliable overall system. Its service life can reach up to 2 million cycles.

Product Features
It employs an AC variable-frequency motor as its core drive mechanism and can be configured for either single-leaf or double-leaf operation. The drive track beam is made of aluminum alloy profiles and features two unique, advanced patented designs. Through the precise engagement between the guide rollers and corresponding grooves in the guide rails, as well as the cooperation between the bottom groove of the movable door and small cylindrical components, when the movable door leaf closes and moves into the groove, the control system leverages the door’s own weight to firmly press the rubber strips around the door’s perimeter and sides, along with the flat rubber pad at the bottom, ensuring tight contact between the door and both the door frame and the floor. This design guarantees the airtightness requirements of the door and results in a structurally sound and highly reliable overall system. Its service life can reach up to 2 million cycles.
The door body features the industry’s only assembly-line production process, employing a one-step foaming molding technique. Its exterior finish includes large, matte stainless steel or aluminum panels, or galvanized steel sheets, and offers a variety of powder-coating colors to choose from.
The power beam and door body are directly mounted onto the wall, making installation quick and easy. Sealing strips are installed around the perimeter, ensuring compliance with the hygiene requirements for hospital use. An independently developed installation process featuring large vertical columns to support the door’s weight effectively addresses safety concerns related to load-bearing capacity inherent in various wall materials currently available. This approach not only helps users save costs and improve cost-effectiveness but also enhances installation efficiency and quality. The dedicated controller and foot-sensor switch offer superior performance—medical staff need only extend their foot into the switch box, and the automatic door will open or close automatically. Manual control via a switch is also available. A unique handle design ensures that even during power outages, the door remains easy to open.

It has obtained CE certification and complies with, but is not limited to, the Machinery Directive (2006/42/EC), the Low-Voltage Electrical Equipment Directive (2006/95/EC), the European Glass Standard EN356, and the EMC Directive (2004/108/EC). Its air-tightness performance meets or exceeds Level 8.

Attention:
1. For the foot-activated switch installation location, please cut the slot according to the dimensions and leave sufficient lead wires extending to the clear height position.
2. If the wall on either side of the door opening is not edged, the location for the lead wire must be pre-reserved within the wall, with the wire end extending to the net height of the door opening.
3. Provide a power outlet, 220V, 50Hz voltage;
4. Doorway dimensions: width × height; (determined based on either the doorway dimensions or the clear passage dimensions)
5. Door body dimensions: Width × Height; (Width = Doorway width + 100, Height = Doorway height + 30)
6. Passage dimensions: (Stainless steel edging: -158, aluminum alloy edging: -168)
