Can multiple burners or multiple shops share one purifier?

Multiple burners in one kitchen can share a unit based on total airflow and simultaneous use; different businesses should usually not share because responsibility, airflow, maintenance and data are hard to separate. When mall restaurants share a riser, each shop should still have or define its own pre-treatment facilities. Checklist: Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
