Our review
Lincoln's manual (IMZ10353) lists a blower of 1,338 g including battery, belt and filters, a 899 g helmet assembly, 170+ / 210+ lpm airflow, an HE (HEPA) particulate filter, and an assigned protection factor of 25 for a loose-fitting PAPR under OSHA guidance. Helmet compliance is ANSI Z87.1-2010, CSA Z94.3 and EN 379.
Its respirator approval line names EN 12941 and AS/NZS 1716, not a NIOSH TC number, even though the manual includes NIOSH caution text. Until Lincoln or the seller confirms US approval, we list it as an alternative only.
Stock was a single unit when we checked.
