What should a food stall consider when choosing an integrated purifier?

Stalls have limited space and concentrated operating periods, so prioritize footprint, fume capture, cleaning access, noise, oil-container capacity and local environmental requirements. Do not choose only by the lowest price; stir-fry stalls need sufficient airflow and purification capacity. 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.
