The S-403 hood provides the essential head, face, neck, and shoulder coverage required by the Versaflo PAPR system, using a simplified design that omits the integrated head suspension found in the S-433 series. For applications where workers use a hood for a single task or shift and discard it, the S-403 economy design delivers PAPR-compatible coverage at the lowest per-use cost in the Versaflo S-series.\u003c\/p\u003e\n\n\u003cp\u003eThe 20-pack format sets the S-403S-20 apart from all other Versaflo hoods — the 5-pack S-133 and S-433 series cost more per hood and carry less inventory per order. Facilities managing PAPR programs in pharmaceutical manufacturing, industrial cleaning, or hazardous remediation where hoods are discarded daily or per-task will find the S-403 20-pack the most practical and economical inventory unit. The 'S' in S-403S denotes the small\/medium size, making this the correct choice for S\/M workers. (There is no 20-pack large variant listed in the current Versaflo lineup.)\u003c\/p\u003e\n\n\u003cp\u003eThe S-403S-20 maintains full compatibility with the Versaflo TR-300, TR-300N+, TR-600, and TR-800 PAPR motor lines via the standard BT-30 breathing tube, so existing motor assets are fully utilized. For programs transitioning workers from the S-133 to a higher-frequency replacement schedule, the S-403 20-pack is a direct drop-in at a lower annualized cost per worker. Facilities should maintain the 5-pack S-433 for supervisors or safety officers who wear PAPRs all day, and use the S-403 20-pack for task-specific or crew-rotation programs.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e20-pack — highest per-order quantity in the Versaflo S-series for lowest per-hood cost\u003c\/li\u003e\n\u003cli\u003eEconomy design: simplified hood for single-shift or single-task replacement programs\u003c\/li\u003e\n\u003cli\u003eSmall\/Medium (S) size\u003c\/li\u003e\n\u003cli\u003eCompatible with TR-300, TR-300N+, TR-600, and TR-800 PAPR motors\u003c\/li\u003e\n\u003cli\u003eLow-linting fabric — suitable for pharmaceutical and clean manufacturing\u003c\/li\u003e\n\u003cli\u003eFull head, face, neck, and shoulder coverage\u003c\/li\u003e\n\u003cli\u003eConnects via standard Versaflo BT-30 breathing tube\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#222;\"\u003e\n\u003cth style=\"padding:8px;text-align:left;\"\u003eSpec\u003c\/th\u003e\n\u003cth style=\"padding:8px;text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSize\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSmall\/Medium (S)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20 hoods per pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Motors\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3M Versaflo TR-300, TR-300N+, TR-600, TR-800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3M Versaflo S-403 (economy)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSuspension\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNone (economy design)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003ePros \u0026amp;
