*To verify clean room requirements, an unloaded base conveyor was tested and did not generate particulate that would be beyond the specified standards. However, the verification does not provide assurance that any or all applications will meet this requirement. Application testing is recommended to ensure clean room standards are being met. Dorner takes no responsibility in the clean room performance of the final conveyor or application.
