Disclaimer:
This checklist is for RFQ preparation only. Final demister style, sizing, density,
material, QA scope and installation details must be checked against your actual
operating conditions, vessel geometry and site standards, then stated in the quotation
or PI. Only documents and services expressly listed and priced into that scope are included.
