So I am looking at putting together a Homefill system for a customer of mine, and have found a few things that concern me based on what I've been told by the salesman I'm dealing with.


The torch this would be running is a GTT Mirage which I am informed has a maximum flow demand of 26 lpm.

The homefill system on an Invacare platinum concentrator only supplies 2 lpm to the compressor. A 5 or a 10lpm unit has the same 2lpm high pressure bypass on the back.

This would give a user about 1.8 hours a day of torch use assuming a maximum flame (marbles, large sculpture).

Even if the larger flame is only on 50% of the time he's working, that's less than 4 hours work per day.

He wants to get 12-14 hours a day on the torch 4-5 days a week. He's a production marble maker, so the bulk of his torch time is spent working on the biggest flame he can tease out of the torch....


I've seen some people here set up the homefills for larger torches, so what's the deal? how do I pull ~15-18k liters of oxygen out a system that only supplies 2880 liters per day?

Can the compressor handle higher throughput than 2lpm? If so, how much?
