Find a supplier
No exact store listing is recorded for this part. Continue with the documented system parts record, the supplier directory, or contact the affiliated UK store or US store to identify the correct regional SKU. An enquiry is not a claim of current stock or that another SKU is a substitute.
The Face Mask Store (UK), USA Face Mask Store and this site have the same owner. These links are commercial enquiry routes.
Listing ≠ endorsement. Confirm availability, approval status and source evidence before purchase or regulated workplace use.
Notes
IMPORTANT: this is the coin-cell battery that powers the auto-darkening ADF lens electronics only — it is NOT the rechargeable PAPR blower battery. Do not confuse with the Miller PAPR blower packs already on file: Gen 1 blower battery 244131 or Gen 2 blower battery 287178. Those power the fan/motor; 217043 powers only the lens.
