OxygenPlus has been helping those in need in the glass industry ever since we opened our doors way back in 1993! Whether you have a Mini torch and need a basic 5LPM concentrator, or you have a large Red Max torch and need a high volume system, we have been here to help!!
Many glass artists start with a small torch like a Nortel Minor. This torch is great for hobbyists and can run off a small propane tank, and a 5LPM oxygen concentrator. If you run a large set up or a production facility you may have multiple stations, multiple torches, and having oxygen set up at each station may not be feasible. In a situation like this, you may run off of a few large "K Tanks" or welding tanks of Oxygen. Many people rent these tanks from local air gas companies, and incur weekly delivery fees, plus the cost to purchase the oxygen. This can get expensive, not to mention cumbersome from having to move those tanks all the time.
Oxygen Concentrators are an excellent choice to use with your glass blowing set up. They require very little maintenance (just a filter change once a year) and can easily be stored under your work space, out of your way. Simply plug the machine in to a power outlet, run the Oxygen line from the machine to your torch, and you are done! All you need to do is turn the concentrator on when you are ready to start, and shut the concentrator off when you are done. The Oxygen Concentrators job is to pull in ambient air from the room around it, filter out the nitrogen, and pass the high purity oxygen to your torch. They will typically run pretty reliably for about 9,000 to 15,000 hours (depending on model) before needing a major overhaul.
When hooking a Concentrator up for the first time, there is a specific way to do so, to ensure that you are not running your concentrator over the maximum LPM it is designed to deliver. All too often we see machines come in with the flow meters turned all of the way open which will always lead to very bad Oxygen Purity, a machine that is alarming, and a customer that thinks something is broken. To alleviate all these issues, please follow these steps:
Thats it, you're done! Now, if you look at the Oxygen Concentrator, the flow meter is likely at a much lower setting now. Probably 2 or 3LPM. THIS IS NORMAL, DO NOT READJUST! You are now effectively controlling your Oxygen Concentrator flow meter with your torch. If you need more oxygen, just open your torch valve. This will ensure that your never run your Oxygen Concentrator over the maximum LPM it was designed to run at. This means you will always have peak Oxygen Purity, and the longest operating life of your machine. If you still don't have enough oxygen, then one machine is not enough, and you should look in to adding a second Oxygen Concentrator to your setup. You can safely do so with a "Y Connector" for your oxygen tubing. Keep in mind that when you daisy chain multiple Oxygen Concentrators, you always add the total amount of LPM between all the machines, but the PSI will only be the same as this most powerful Oxygen Concentrator. For instance, if you have a 5LPM 5PSI machine, and a 5LPM 9PSI machine, hook them together, you will NOT have 10LPM 14PSI, you will have 10LPM 9PSI. It is always best to daisy chaing the same makes and models together to ensure compatibility, and also it is a good idea to use 1 way check valves in like before the Y connector to make sure that there is no oxygen back flow into the other machines that may cause an alarm. Flashback arrestors and Oxygen Regulators are NOT NEEDED when using an Oxygen Concentrator. Adding these will only drop the quality and pressure of the oxygen you receive from your Oxygen Concentrator.
