3M Versaflo TR-300+ PAPR questions
Which filter does the TR-300+ take? Only the TR-3712N HE particulate filter (3M Cartridge and Filter Summary; TR-300+ parts sheet). Gas and vapor cartridges are TR-600 and TR-800 items.
How long does the TR-332 battery run? 8 to 12 hours per the 3M Versaflo PAPR comparison sheet.
Which headtops are approved with the TR-300+? The CEL lists TR-300+ PAPR systems with S-Series, M-Series, H-Series, 9100 and 9100 MP headgear and the TR-3712N filter (TC-21C-1296 to 1306) and with the G5-01 (TC-21C-1326).
What is the APF? It depends on the headtop: S-103/S-133 headcovers 25; S-400 to S-800 hoods 1,000; M-100/200/300 loose-fitting 25; M-400 helmet 1,000 (3M S-Series sheet and M-Series user instructions, quoting OSHA Table 1).
What is the difference between TR-300+, TR-600 and TR-800? TR-300+: HE filter only; TR-600: HE plus gas and vapor cartridges and two battery sizes; TR-800: the same filters in an intrinsically safe unit (3M PAPR comparison). The guide linked below sets them side by side.
