# PAPR Parts Intelligence — full dataset

> The web’s first verified welding-PAPR parts database, rendered as markdown for LLM ingestion. Every fitment claim carries one of four approval tiers and cites dated primary-source evidence.

Source: https://paprparts.com · JSON API: https://paprparts.com/api/index.json
License: Free to use with attribution to paprparts.com. Every claim traces to a dated primary source; verify with the manufacturer and your approval label before purchase or use.

IMPORTANT: This is an information resource, not safety advice. PAPR systems are approved as complete tested systems under EN 12941 / EN 12942 (UK/EU), NIOSH 42 CFR 84 (US) and AS/NZS 1716 (AU/NZ). Using parts outside the manufacturer’s approval documentation voids the approval and may be unlawful in a regulated workplace.

## Approval-tier taxonomy

- **officially-approved**: The part appears on the approval documentation for the complete system: the NIOSH approval label, the CE/UKCA declaration of conformity, or the manufacturer’s approval documentation.
- **manufacturer-listed**: The manufacturer lists the part as a replacement part or accessory for the system (official parts list, user instructions, or catalogue) — but the listing itself is not the approval document.
- **physically-compatible**: The part attaches, powers or fits the system — but it is NOT on any approval documentation. Using it voids the system approval and, in a regulated workplace, may breach OSHA 1910.134 / COSHH duties. Documented for honesty, never endorsed.
- **workplace-regulatory**: A claim about whether a configuration is acceptable in a workplace respiratory-protection programme (OSHA 1910.134 / COSHH / EN / AS-NZS context) — the layer above the hardware. General information, not advice for a specific workplace.

## Data-status levels

- **verified**: We checked the primary source ourselves.
- **audit-supported**: Supported by the research/verification audit but not yet re-checked live against the primary source.
- **needs-verification**: Known gap or known-error area — published only with a warning badge; treat details with caution.

### 3M Speedglas Adflo PAPR (3m-adflo)

- URL: https://paprparts.com/system/3m-adflo/
- Status: current
- Data status: verified
- Approvals: EN 12941:1998+A2:2008 — TH2 or TH3 — depends on headtop AND filter (e.g. G5-01 TH3, 9100 Air TH2 per 3M matrix) [UK/EU]; NIOSH 42 CFR 84 — HE (approval-label specific) [US]; AS/NZS 1716:2012 — Respiratory Protective Devices [AU/NZ]
- Headtops: Speedglas 9100-Air; Speedglas 9100 FX-Air; Speedglas 9100 MP; Speedglas G5-01; Speedglas G5-03 Pro Air; Versaflo M-series (with correct tube/duct)
- Summary: 3M's belt-mounted welding PAPR, used with Speedglas 9100-Air, 9100 FX-Air, 9100 MP, G5-01 and G5-03 Pro Air headtops (and Versaflo M-series with the correct breathing tube/duct). Approved combinations are defined by the NIOSH approval label / EN certificate for the complete system — always check the label for your exact headtop, tube and filter stack.
- Generation note: Part numbers are region- and generation-sensitive: US/legacy numbering (15-xxxx-xx, 35-xxxx-xx) coexists with current EMEA numbering (83xxxx / 836xxx). Records on this site carry region fields for this reason.
- Notes: Exact warning from the 3M user instructions: "Do not repair or modify any component of this system. Do not use with parts or accessories other than those manufactured by 3M as described in these User Instructions or on the NIOSH approval label for this respirator. Failure to do so may adversely affect respirator performance and result in sickness and death." Key tube constraint: the SG-50W breathing tube can only be used with 9100 Air, 9100 FX Air, 9100 MP and M-series headgear, is REQUIRED for HE+OV/AG combinations on 9100-Air/9100 MP, and must be used with M-400 headgear in any Adflo configuration.

### 3M Speedglas Speedglas 9000 / 9002 with Fresh-air C & legacy Adflo (discontinued) (3m-speedglas-9000-fresh-air)

- URL: https://paprparts.com/system/3m-speedglas-9000-fresh-air/
- Status: discontinued
- Data status: verified
- Approvals: EN 12941 (legacy certification era) — check your unit's original documentation and label [UK/EU]
- Headtops: Speedglas 9000 shield for respiratory protection (46 08 00, without welding filter); Speedglas 9000 FlexView shield for respiratory protection (44 28 00); Speedglas 9002D/9002V/9002X welding filters (40 00 40 / 40 00 70 / 40 00 80)
- Summary: The discontinued Speedglas 9000/9002 helmet series, run either from legacy Adflo blowers or the Fresh-air C compressed-air system. Many units are still in field use. We hold the official period parts list (3M Speedglas catalogue), so the exact part numbers welders hunt for are documented here — including 43 30 00, the headband with air duct. Availability today is second-hand or old stock only; nothing on this page implies current manufacturer support.
- Generation note: Key respiratory-protection spares from the official catalogue parts list: headband WITH air duct 43 30 00; air duct alone 43 30 10; headband without duct 43 30 60; face seal 43 40 01; air spreader 43 50 00; battery cover 43 10 00. Legacy Adflo consumables shared the 83xxxx series still partly current today (particle filter P SL 83 70 10/20/80, prefilter 83 60 10, spark arrestor 83 60 00, gas filter A1B1E1 83 72 42). Legacy batteries: 83 76 20 standard / 83 76 21 Heavy-Duty (NiMH era) → superseded by Li-ion 837630/837631 (EMEA) and 35-1099-07 (US). Fresh-air C spares: filter element 85 90 01 (292 SR49/SR79), gasket kit 85 90 04, regulators 85 20/21 series; the AFU500F/W filtration units were replaced by ACU-02/ACU-01 Aircare systems in August 2007.
- Notes: This is the site's moat category: manufacturers won't maintain guidance for discontinued systems. Identification data here is primary-sourced; availability is second-hand only, and the honest recommendation for regular users is often to retire the system — see the rescue guide.

### CleanSpace WORK / CST PRO (hose-free PAPR) (cleanspace-work)

- URL: https://paprparts.com/system/cleanspace-work/
- Status: current
- Data status: verified
- Approvals: EN 12942:1998+A1:2002+A2:2008 — TM3 P R SL (tight-fitting; CE and UKCA) [UK/EU]; NIOSH 42 CFR 84 — TC-21C-1269 Class HE (with Half Mask + HI CAPACITY filter) [US]; AS/NZS 1716:2012 — PAPR-P3 (P2 with Half Mask) [AU/NZ]
- Headtops: Half-mask with head harness (tight-fitting — requires fit testing)
- Summary: CleanSpace's distinct battery-on-mask architecture: no belt, no hose — the blower sits on the half-mask itself (<400 g) with AirSensit adaptive airflow. Relevant to welders for grinding/fabrication particulate protection, but it is NOT a helmet PAPR. CRITICAL standards distinction: as a tight-fitting half-mask system, the CST PRO is certified under EN 12942 TM3 (tight-fitting masks) — not EN 12941, which covers loose-fitting hoods/helmets like Adflo or EPR-X1. The two standards have different classes (TM vs TH), different fit requirements (tight-fitting masks need fit testing), and different protection assumptions. Never treat them as interchangeable.
- Generation note: Filters are proprietary CleanSpace particulate (P3/HE) units. Because the system is tight-fitting, workplace use requires face-fit testing — a materially different compliance path from loose-fitting helmet PAPRs.
- Sources:

This record exists partly as a documented correction — the original research described CleanSpace under EN 12941 as a blanket claim, which is wrong for the tight-fitting systems.

### ESAB EPR-X1 / EPR-X1.1 PAPR (esab-epr-x1)

- Status: discontinued
- Data status: audit-supported
- Approvals: NIOSH 42 CFR 84 — HE (approval-label specific) [US]
- Headtops: T94i-R (flip-front); Miller hard-hat PAPR headtops
- Summary: First-generation Miller welding PAPR (used with the T94i-R flip-front and hard-hat headtops). Kept as a SEPARATE system record from the Gen 2 PAPR II because batteries and filters are NOT interchangeable across generations — the single biggest user trap in the Miller ecosystem.
- Generation note: Gen 1 requires battery 244131. The Gen 2 battery 287178 does NOT fit Gen 1 (distributor-confirmed). A 269930 battery-contact repair kit exists for Gen 1 units.
- Sources:
  - https://www.millerwelds.com/safety/papr-supplied-air-respirators (manufacturer-page, verified 2026-07-04) — Miller lists PAPR II (Gen 2) parts officially; Gen 1/Gen 2 battery incompatibility is distributor-evidenced per the verification audit. Capture exact Gen 1 documentation in Phase 1.

- Status: current
- Data status: audit-supported
- Approvals: NIOSH 42 CFR 84 — HE (approval-label specific) [US]
- Headtops: T94i-R (flip-front); Miller hard-hat PAPR headtops
- Summary: Second-generation Miller welding PAPR (PAPR II). Uses its own battery (287178) and filters (287170-series) which are NOT backward-compatible with Gen 1 units — Gen 1 requires battery 244131. Always identify your generation before ordering parts.
- Generation note: Gen 2 battery 287178 (~8 h runtime) with Gen 2 charger 282077. Filters 287170-series HEPA. None of these fit Gen 1.
- Sources:
  - https://www.millerwelds.com/safety/papr-supplied-air-respirators (manufacturer-page, verified 2026-07-04) — Miller officially lists PAPR II HEPA filters, prefilter and Gen 2 battery; distributor evidence confirms Gen 2 battery is not Gen 1 compatible.

### 3M 15-0299-99 — Adflo High-Efficiency (HE) Particulate Filter (3m-15-0299-99)

- URL: https://paprparts.com/part/3m-15-0299-99/
- Category: filter
- Lifecycle status: current
- Data status: verified
- Regions: US
- Specs: Case packs: 15-0299-99X02 (2/case), 15-0299-99X20 (20/case), 15-0299-99X80 (80/case) · Mandatory stack: HE filter, pre-filter and spark arrestor must ALWAYS be used together · Altitude limit: Above 5,000 ft MSL the Adflo may ONLY be used with the HE filter alone (no cartridge/odour pad); max 10,000 ft
- Fits:
  - System 3m-adflo — tier: manufacturer-listed
    - Evidence: https://multimedia.3m.com/mws/media/1173591O/3m-adflo-welding-papr-assembly-user-instructions.pdf (manufacturer-manual, verified 2026-07-04) — Table 2 of the official 3M Adflo user instructions (August 2025).

- Notes: US part numbering (current EMEA/UK pages use 83xxxx-series numbers — region mapping pending). The HE filter can be stacked with the OV/AG cartridge or nuisance odour pad, but never both together and never the cartridge/pad alone; on 9100-Air and 9100 MP helmets the HE+OV/AG combination requires the SG-50W breathing tube. The HE filter and pre-filter CANNOT be cleaned — replace them; the metal spark arrestor can be washed and reused.

### 3M 15-0499-99 — Adflo Organic Vapour / Acid Gas (OV/AG) Cartridge (3m-15-0499-99)

- URL: https://paprparts.com/part/3m-15-0499-99/
- Category: gas-cartridge
- Lifecycle status: current
- Data status: verified
- Regions: US
- Specs: Case packs: 15-0499-99X02 (2/case), 15-0499-99X06 (6/case); a 15-0399-99 OV/AG cartridge also exists (X02/X06) · Acid gas approval: NIOSH approval for sulfur dioxide, chlorine, hydrogen chloride · Mandatory stack: Must ALWAYS be used with the HE filter, pre-filter and spark arrestor — never alone, never combined with the odour pad · Runtime impact: Battery runtime drops to ~5.5 h with the OV/AG cartridge fitted

- Notes: Correction captured against the original research: the manual lists TWO OV/AG cartridge part numbers (15-0399-99 and 15-0499-99) and the nuisance odour pad is 35-0799-99 (assembly 35-0699-99), not a 15-0299-99X suffix. Cartridge service life must be pre-determined via a change-out schedule — the filter-loading indicator tells you nothing about gas/vapour life.

- Notes: The single highest-pain consumable in the welding PAPR world. OEM price (~£230 UK) drives welders toward rebuild services (e.g. MTO, frequently backordered), rebuilt/OSI-type replacements, and 3D-printed power-tool battery adapters. Rebuilds and adapters are NOT approved: 3M's user instructions state "Do not repair or modify any component of this system. Do not use with parts or accessories other than those manufactured by 3M as described in these User Instructions or on the NIOSH approval label," and power-tool packs lack this pack's protection circuitry. See the Adflo battery decision guide.

Backward compatibility with the older e3000 blower is distributor-confirmed only (Welding Supplies from IOC: "can be used in the older e3000 and newer e3000X") — treat as physically-compatible pending an Optrel manual/DoC confirmation.
