What fire-protection features should an integrated cooking fume purifier have?

Look for fire baffles, duct fire dampers, overload protection, electrostatic fault protection and reliable grounding, while regularly removing grease from the hood and purification sections. A purifier does not replace cooking-area fire suppression, and the kitchen still needs suitable fire-fighting equipment. 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.
