Cleanroom Sliding Doors
Cleanroom sliding doors play a crucial role in maintaining the cleanliness, stability, and efficient passage of personnel and equipment in clean rooms, such as in industries like semiconductors, biomedicine, and precision manufacturing.
The good sealing of clean sliding doors can effectively reduce air infiltration, prevent air cross contamination between clean and non clean areas, and ensure the cleanliness of the production environment, meeting the industry's requirements for high-precision production environments.
The automatic opening and closing function of clean sliding doors facilitates quick entry and exit of personnel and equipment, reduces waiting time, and thereby improves overall production efficiency.
Structure of cleanroom sliding doors
The cleanroom sliding door is mainly composed of the door body, guide rail, driving device, control system, sensing device.
-
The door body is usually made of high-strength, corrosion-resistant, and smooth surface materials, such as stainless steel, aluminum alloy, etc., to meet the strict requirements of clean rooms for environmental cleanliness and hygiene.
-
The core of the door body may be filled with materials that provide insulation, sound insulation, fire prevention like paper honeycomb, aluminum honeycomb, rock wool etc. to enhance its overall performance while ensuring the strength of the door.
-
The guide rail is the track for the operation of the door body, usually installed above and below the door, playing a role in supporting and guiding the translation of the door body. The accuracy and stability of the guide rail directly affect the smoothness and reliability of the door operation. It is usually made of high-quality metal materials and the surface is precision machined to ensure that the door can run smoothly and noiselessly.
-
The driving device includes components such as motors, reducers, and transmission mechanisms, and is the core part that provides power to the door body, to achieve the opening and closing of the door.
-
The control system is to achieve automated operation of the door. It usually includes a main control board, power module, control buttons, etc., which can accurately control the running speed, switch direction, safety protection and other functions of the door.
-
Induction devices are used to detect whether there are people or objects approaching around the door, commonly including infrared induction detectors, microwave induction detectors, etc. When the sensing device detects a signal, it will immediately transmit it to the control system, triggering the opening action of the door.

Advantage of cleanroom sliding doors
-
In terms of space utilization, cleanroom sliding doors have significant advantages. Taking operating rooms as an example, when the automatic sliding door is opened, the door body moves along the guide rail to one side without occupying additional indoor space, providing more spacious space for surgical operations and personnel activities.
-
The automatic opening and closing function of the automatic cleanroom sliding door enables it to quickly respond to the entry and exit needs of personnel. When personnel approach, the sensing device quickly detects the signal, and the automatic sliding door quickly opens, allowing personnel to pass directly without waiting. When leaving, the door can automatically close again. Especially in clean room areas with high personnel flow, such as hospital corridors and material transfer channels in pharmaceutical workshops.
-
When the automatic cleanroom sliding door is closed, it can achieve a tight fit between the door body and the door frame. Through special sealing strips or sealing structures, it effectively reduces air infiltration and leakage, preventing cross contamination of air inside and outside the clean room.
Disadvantage of cleanroom sliding doors
-
Automatic sliding doors have higher cost due to their complex structure and advanced technology, including motors, drive devices, control systems, induction devices, etc.
-
The installation of automatic sliding doors requires high precision and professional skills.
-
Automatic sliding doors have a complex electronic and mechanical system, making it difficult to troubleshoot and repair problems once they fail.
Application of cleanroom sliding doors
-
Electronic industry
In the electronics industry, especially in the field of microelectronics manufacturing, there is a high demand for cleanliness in the production environment. The automatic control function of the automatic sliding door enables efficient operation of the production process, ensuring the stability and reliability of the microelectronics production environment, and helping to improve product yield.
-
Pharmaceutical industry
The clean workshop of a pharmaceutical factory is a critical area for drug production, and must strictly comply with relevant hygiene standards and regulations to ensure the quality and safety of drugs.
Due to the strict prohibition of cross contamination in the drug production process, the automatic sensing opening function of the automatic sliding door allows operators to avoid manual contact with the door body, reducing the possibility of bacteria and pollutants carried by hands entering the clean area.
Moreover, its excellent sealing performance can effectively isolate the air between different clean areas, prevent the spread of pollutants such as dust and microorganisms generated during drug production in the workshop, meet the strict hygiene requirements of the pharmaceutical industry for the production environment, and provide strong guarantees for the quality of drugs.
-
Food industry
The threshold free design of the automatic sliding door facilitates the entry and exit of material transportation carts and improves logistics efficiency.
At the same time, its easy to clean door surface can effectively prevent the growth of dirt and bacteria, meeting the strict requirements of the food industry for hygiene and cleanliness.
In addition, the quick closing function of the automatic sliding door can reduce the time for external air to enter the clean room, and lower the risk of contamination of food raw materials and finished products by dust, microorganisms, and other pollutants in the air.
