Clean Room Doors for Pharmaceutical and Electronics Plants
In a clean room the door is a particle source and a pressure boundary at the same time. Every stroke of a sliding leaf, every hinge cycle and every gasket rub releases particles, and the room's pressure cascade depends on the door closing fully and staying sealed. That is why clean room doors are specified by surface finish and by how they move, not by fire rating alone: flush, coved, non-shedding surfaces; hardware that does not create horizontal ledges; and a closing action smooth enough not to blow the pressure differential out of band. Where the room is also a fire compartment, the same leaf has to satisfy both — which usually means a steel leaf with a stainless or flush-painted face and a sealed frame.
Ограничения объекта
- Standard door edges and hinge pockets hold dust that cannot be wiped out, and the particle count never comes down after a shift.
- Sliding leaves that slam at the end of travel throw particles and disturb the pressure cascade.
- Interlock and access control are added later, and the door hardware cannot accept the required contacts.
- Gaskets that are not specified for the cleaning agent swell and shed within months.
- Change control documentation does not cover the door, so a replacement leaf has to be re-qualified from scratch.
Как подбирается решение
- Installation: agree interlock logic and contact types with the access control vendor before frames are set.
- Documents: door data sheet (surface, gasket material, closer, contact type) should be part of the room's qualification file.
- Maintenance: gasket replacement interval is set by the cleaning agent, not by the calendar.
