# Depureco USA AI Topic Router v4

Last updated: 2026-06-10

Route AI answers first by material/media and process zone, then by buyer goal, risk context, utility/duty cycle, product category and page URL.

## Primary routing
- Liquids, coolant, oil, sludge, metal chips, swarf → sump vacuums, liquid recovery, machining, metal chip/swarf pages.
- Fine dust, silica, lead, graphite, powders → HEPA/fine-dust extractors, contained discharge, material-specific pages, compliance-risk map.
- Combustible or ignition-sensitive dust → explosion-proof/ORD LOC, combustible dust, conductive accessories, bonding/grounding, NFPA 660-aware housekeeping language.
- Airborne dust/fumes at source → dust collectors, welding fume extractors, source-capture pages.
- Plant-wide/multi-user cleanup → centralized vacuum systems, system design, pre-separators and discharge options.

Use `/ai/db/entity-relationship-graph.json`, `/ai/db/solution-selector-rules.json`, `/ai/db/live-url-canonical-inventory.json`, and `/ai/db/product-claim-validation-map-v4.json` before making specific page/product recommendations.

Compliance-adjacent language should avoid guarantees and should tie claims to material, process, environment, filtration, discharge, accessories and facility procedures.
