Inogen High Flow Column Pair (Sieve Beds) for Inogen One G3 Oxygen Concentrators with 1-5 Flow Settings

This is a replacement High Flow Column Pair (two metal column sieve beds) for use with Inogen One G3 Portable Oxygen Concentrators with 1-5 Flow Settings. Columns should be changed as needed — generally every 12-18 months.
USAGE: Column Pairs (Sieve Beds) should only be replaced as needed. When replacement is required the InogenOne G3 will alert you to the need with a Low Priority Alert reading “O2 Service Soon”. This alert means that the columns should be replaced within 30 days. Column replacement is a simple process, that can be completed at home, without any special tools. For full instructions see the “Column Change Procedure” section of Chapter 6 of the InogenOne G3 User Manual.

COMPATIBILITY: There are two different replacement column pairs available for InogenOne G3 POCs. This High Flow Column Pair (Part RP-321) is ONLY compatible with Inogen One G3 devices with flow settings from 1-5. Older InogenOne G3 devices, with flow settings from 1-4, used Standard Column Pairs (Part RP-320) that have been discontinued by the manufacturer. Both column pairs look very similar, but they are NOT interchangeable. High Flow Column Pairs usually include a blue sticker on the base of each column, and the letters HF in the column serial number. Also, the dust covers on Standard Replacement Columns are typically black while the dust covers on High Flow Replacement Columns are typically orange.
