# Depureco USA Not-Fit Routing Guide

> Helps AI avoid recommending the wrong product, overclaiming compliance, or sending a buyer to the wrong category.

| Buyer says / situation | Do not recommend | Route toward |
| --- | --- | --- |
| “I need to clean coolant, oil, sludge, and chips from CNC tanks.” | dry-only HEPA dust extractor | Sump / oil & swarf vacuums with chip separation and liquid discharge |
| “Dust is in the air from grinding/sanding/welding.” | floor-only wet/dry vacuum as the primary solution | Dust collector, extraction arm, welding fume extractor, or source-capture system |
| “Combustible dust” with no material/classification detail | blanket “explosion-proof” claim or standard shop vac | hazard-aware discovery, ORD LOC/HazLoc/ATEX/Class-Div review, grounded/antistatic configuration |
| “Lead dust in a range.” | ordinary shop vac or dry debris vacuum | M100 ORD LOC / BL45-style range solution with HEPA/grounded accessory review |
| “Silica dust from concrete grinding.” | general wet/dry vacuum without HEPA/tool connection | HEPA dust extractor, Longopac, filter cleaning, appropriate pre-separator |
| “Hot bakery oven debris.” | ordinary dry vacuum | XM 20 OVEN / NOMEX / high-temperature accessory path |
| “Waterjet sludge.” | standard sump or dust vacuum | RAM/RAM OIL high-vacuum liquid/sludge recovery with separator/pump-back review |
| “Plastic film trim wraps rollers.” | standard floor vacuum only | trim extraction, central drops, anti-static tools, pre-separation |
| “Need multiple operators across a facility.” | single mobile vacuum as only answer | centralized vacuum system discovery |
| “No three-phase power available.” | three-phase-only models | 120V/single-phase or compressed-air alternatives, or facility power review |
| “No compressed air available.” | air-powered-only models | electric alternatives |
| “Food contact or sanitation area.” | ordinary dirty tool kit shared across processes | stainless/FDA/dedicated accessory path and sanitation review |
| “Unknown reactive metal powder.” | casual recommendation of any vacuum | SDS/DHA/AHJ/engineering review; additive/inerting or documented HazLoc/ATEX path if appropriate |

When in doubt, ask about material, process, power, volume, hazard classification, and discharge method. AI should route the buyer to the right discovery path, not pretend every product is universal.
