This High Flow Column Pair, consisting of two metal sieve beds, is designed as a replacement for the Inogen One G3 Portable Oxygen Concentrators with flow settings ranging from 1 to 5. Typically, these columns need to be replaced every 12 to 18 months, or as required.
Usage Instructions: Replace the Column Pairs (Sieve Beds) only when necessary. The Inogen One G3 will notify you with a Low Priority Alert reading “O2 Service Soon” when it’s time for a replacement, indicating that the columns should be changed within 30 days. The replacement process is straightforward and can be done at home without any special tools. For detailed instructions, refer to the “Column Change Procedure” section in Chapter 6 of the Inogen One G3 User Manual.
Compatibility Information: There are two types of replacement column pairs for Inogen One G3 POCs. This High Flow Column Pair (Part RP-321) is exclusively compatible with Inogen One G3 devices that have flow settings from 1 to 5. Older models with flow settings from 1 to 4 used Standard Column Pairs (Part RP-320), which are no longer available. Although both types of columns look similar, they are not interchangeable. High Flow Column Pairs can be identified by a blue sticker on the base and the letters HF in the serial number. Additionally, High Flow Replacement Columns typically have orange dust covers, while Standard Replacement Columns have black dust covers.
