WC Safety Editorial Pick: The S-403S-20 is the volume-replacement choice in the Versaflo hood lineup — 20 economy hoods per pack, lowest per-unit cost, for facilities that replace hoods at the end of each shift or task.
The 3M Versaflo S-403S-20 is a 20-pack of economy-tier S-series PAPR hoods, designed for high-volume replacement programs where per-hood cost is the primary purchasing criterion. 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.
The 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.)
The 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.

Frequently Asked Questions
How many hoods are in the S-403S-20?
20 hoods per pack — the highest per-order quantity in the standard Versaflo S-series hood lineup.
What size is the S-403S?
The S-403S is the small/medium size. For large-size workers on a high-volume program, use the S-133L-5 5-pack as the closest equivalent.
What motors are compatible with the S-403S?
The S-403S is compatible with all 3M Versaflo TR-series motors: TR-300, TR-300N+, TR-600, TR-600HIK, TR-800, and TR-800HIK.
Is the S-403 better than the S-133 or S-433?
The S-403 is the economy tier with the highest pack quantity. The S-133 is the standard entry-level (5-pack); the S-433 is the premium hood with head suspension. For single-use programs, the S-403 20-pack is the most economical. For all-day wear, the S-433 provides better fit and comfort.
Does the S-403S-20 require a breathing tube?
Yes. The BT-30 breathing tube connects the S-403 hood to the PAPR motor unit. The BT-30 is sold separately.
Is the S-403S-20 NIOSH approved for PAPR use?
The S-403S is part of the 3M Versaflo NIOSH-approved PAPR system when used with an approved TR-series motor and appropriate filter combination.
Can I use the S-403S on a TR-800 intrinsically safe PAPR?
Yes. The S-403S is compatible with the TR-800 series, including the intrinsically safe variants for Zone 1/Zone 2 environments.
Does the S-403 provide the same level of protection as the S-433?
Yes — the protection level (APF) of a loose-fitting PAPR hood is determined by the motor, filter, and overall system NIOSH approval, not by which S-series hood is used. The S-403 and S-433 provide the same protection when used as part of the same NIOSH-approved system. The S-433's advantage is ergonomic (head suspension), not a higher APF.
How do I store the S-403S-20 hoods?
Store in the original packaging in a clean, dry area away from UV light, ozone sources, and chemical vapors. Do not crush or compress stored hoods.
Can I reuse the S-403 economy hood?
The S-403 can be decontaminated and reused if it shows no visible damage or contamination and your program specifies reuse. For single-use programs (most common with economy hoods), discard after each shift or task.
Is the S-403S fabric low-linting?
Yes. The S-403S uses a low-linting fabric consistent with pharmaceutical and clean manufacturing applications.
Where can I buy the BT-30 breathing tube for the S-403?
The BT-30 is available through WC Safety at 3M Versaflo BT-30 Breathing Tube.
