Selecting Robots for Cleanroom Use
Cleanroom ratings are about particles and materials, not just seals.
What to check
| Item | Consideration |
|---|---|
| Particle emission | Measured class of the robot itself |
| Materials | Low-outgassing surfaces and lubricants |
| Ventilation | Where exhaust and filtration are required |
| Cleaning | Compatibility with the cleaning agents used |
| Documentation | Certificates stating the achieved class |
Practical notes
- The cell envelope can be dirtier than the robot; assess the whole system.
- Maintenance tasks can breach cleanliness; plan the procedure.
- Confirm which standard class the certificate refers to.
Cleanroom requirements come from the process and the applicable standard. Confirm with the facility and the supplier.
