Short answer: the 3m versaflo s-655 papr hood assembly with inner collar is covered below on the specifications its own listing publishes, the standards it is certified to, and who it suits.
WC Safety Editorial Pick: The S-655 is the premium-protection Versaflo hood for environments where the neck and shoulder area needs a tighter containment barrier — the inner collar creates an additional seal that the standard S-133 and S-433 hoods do not provide.
The 3M Versaflo S-655 Hood Assembly distinguishes itself within the Versaflo S-series by the addition of an inner collar — an elasticated neck band that creates a secondary containment barrier at the neck opening. In environments where chemical mists, aerosols, or airborne particles could infiltrate the hood from the bottom opening during physical work (bending forward, reaching overhead, operating in ventilated booths with turbulent airflow), the S-655's inner collar reduces this ingress pathway. It is the hood of choice for pharmaceutical spray coating operations, chemical process environments, and multi-component painting applications.
Unlike the basic S-133 and S-403, which rely on gravity and the drape of the hood skirt to minimize bottom-entry contamination, the S-655 collar actively seals against the wearer's neck. This is most relevant in Class II and Class III pharmaceutical containment environments, in spray finishing booths where paint mist is present at the neck level, and in decontamination applications where workers must maintain contamination control even during dynamic body movements. The S-655 maintains full compatibility with Versaflo TR-300 and TR-600 motors via the BT-30 breathing tube.
Procurement teams selecting between S-series hoods for chemical environments should evaluate the S-655 against the S-133 and S-433: if your hazard assessment indicates significant risk of aerosol ingress from below the hood during work, the S-655's inner collar addresses that gap at a modest premium over basic hoods. For environments where particulate control (not aerosol ingress) is the primary concern, the S-433 or S-133 series provides adequate coverage at lower cost. The S-655 is typically sold as a single unit rather than a 5-pack, reflecting its higher per-unit cost and use in programs where controlled replacement is tracked.
3m versaflo s-655 papr hood assembly with inner collar — what the listing actually specifies
Key Features
An air-purifying respirator filters air, it does not supply any. Under 29 CFR 1910.134 no air-purifying respirator may be worn in an atmosphere that is IDLH or oxygen-deficient (below 19.5% oxygen). Those conditions require a supplied-air respirator or an SCBA, and no filter or cartridge rating changes that.

Frequently Asked Questions
What is the inner collar on the 3M Versaflo S-655?
The inner collar is an elasticated neck band sewn into the interior of the hood at the bottom opening. It seals against the wearer's neck, creating a secondary containment barrier that reduces aerosol or chemical mist ingress from below the hood.
When should I choose the S-655 over the S-433?
Choose the S-655 when your hazard assessment identifies risk of aerosol or chemical mist entering the hood from the neck opening during dynamic work. Choose the S-433 when fit and stability are the primary needs but aerosol ingress from below is not a significant risk.
Which PAPR motors are compatible with the S-655?
The S-655 is compatible with 3M Versaflo TR-300, TR-300N+, and TR-600 series PAPR motors. Verify TR-800 compatibility with 3M before use in intrinsically safe applications.
Does the S-655 come in multiple sizes?
The S-655 may be available in a standard adult size. Confirm size availability with WC Safety or 3M, as the inner collar's elasticated construction accommodates a moderate range of neck circumferences.
Is the S-655 appropriate for pharmaceutical OEB containment environments?
Yes. The S-655 is commonly used in pharmaceutical manufacturing at high occupational exposure band (OEB) levels, where containment of potent compounds requires both respiratory protection and minimization of dermal exposure pathways.
Does the S-655 require a breathing tube?
Yes. The S-655 uses the standard 3M Versaflo BT-30 breathing tube to connect to the PAPR motor unit.
Is the S-655 fabric low-linting?
Yes. The S-655 uses a pharmaceutical-grade low-linting fabric, consistent with use in controlled manufacturing and laboratory environments.
How does the S-655 compare to a fully encapsulating suit for chemical protection?
The S-655 is not equivalent to a fully encapsulating suit — it provides respiratory protection plus containment at the neck, but the body and hands are not protected. For full-body chemical protection, combine the S-655 with appropriate chemical-resistant coveralls, gloves, and boots.
Is the S-655 reusable?
The S-655 can be decontaminated and reused if your facility's contamination control program specifies reuse procedures and the hood shows no visible damage or degradation. Confirm reuse protocols with your industrial hygienist.
How do I clean the S-655 after use in a chemical environment?
Follow 3M's cleaning instructions for the S-655 and your facility's decontamination procedures for the specific chemical hazard. Do not launder with standard detergent without confirming chemical compatibility and the effect on the fabric's protection properties.
Does the inner collar in the S-655 affect breathing comfort?
The inner collar seals at the neck but does not restrict breathing — the PAPR motor provides positive-pressure airflow that maintains comfortable breathing conditions within the hood regardless of the collar seal.
Where can I buy the S-655 breathing tube?
The BT-30 breathing tube for the S-655 is available at 3M Versaflo BT-30 Breathing Tube through WC Safety. Written by Steven Eaton , WC Safety — PPE Specialist with 10+ years sourcing and evaluating industrial respiratory protection. All specifications are manufacturer-verified or NIOSH-documented.
