The wall-penetrating design for pharmaceutical equipment refers to a layout in which part of the equipment is arranged across a partition wall into another room, thereby saving processing space. The equipment’s transfer, control, and maintenance areas are located in auxiliary zones. Through engineering and technical measures, the layout ensures separation between two cleanroom zones of different cleanliness levels.

　　(1) Save on factory usage costs

　　Drug manufacturing has stringent requirements for the production environment. By reducing the cleanroom area without affecting the production process or operations, environmental costs can be lowered. The equipment features a wall-penetrating design, and the process area occupied by the equipment itself depends on the specific factory in which it is used.

　　(2) Promote self-cleaning of factories and equipment

　　Due to the maintenance requirements of traditionally designed pharmaceutical equipment, cover components such as lids need to be designed as detachable, which compromises sealing performance. In contrast, wall-mounted pharmaceutical equipment, positioned close to the high-grade cleanroom side, does not require disassembly after installation. Therefore, such equipment can be designed as fixed or monolithic units, reducing the need for joint machining and resulting in a cleaner equipment appearance that facilitates easy purification of the process area—particularly during operations like cleaning and disinfection.

　　(3) The design and manufacturing of the equipment itself can be optimized.

　　Conventionally designed equipment may contaminate process areas due to rusting of components, leakage of lubricants from transmission parts, debris generated by friction between pulleys and belts, or the presence of necessary inspection doors. After implementing stringent isolation measures between the process area and auxiliary area for wall-penetrating equipment configurations, the aforementioned issues can be confined to the auxiliary area. The design of the process-area portion can ensure that the equipment meets the required cleanliness standards while also addressing challenges related to strength, transmission efficiency, heat dissipation, and cost, thereby optimizing the equipment design to comply with GMP requirements.

　　(4) Can reduce noise and improve the comfort of the working environment.

　　Placing transmission equipment in an auxiliary area and using isolation measures can reduce transmission noise and help improve the comfort of the working environment.

　　(5) The equipment is easy to operate.

　　Wall-mounted touchscreens and other operator interfaces can be considered for wall-through layouts, which do not occupy space in the process area and facilitate both the use and cleaning of the operator interface.

　　(6) Easy to maintain

　　The overall design of wall-penetrating layout equipment can centralize the auxiliary areas for various devices. On the one hand, it shortens the pipelines for water, electricity, gas, and steam supplied by the factory, facilitating maintenance of production facilities and reducing operational costs. On the other hand, the dedicated maintenance area designed specifically for pharmaceutical equipment allows for convenient connection and installation of water, electricity, gas, steam, and equipment, thereby promoting comprehensive maintenance of both the equipment and the facility.

　　(7) Maintenance work does not affect the process scope.

　　After isolating the main equipment, maintenance work is carried out within the designated maintenance area to prevent communication between cleaning zones of different levels during maintenance operations, thereby preserving the cleanliness. Here, a wall-through layout enables maintenance without disrupting the production of other equipment, ensuring that maintenance activities have minimal impact on drug quality and fully comply with GMP requirements.
