I just came across an Invacare Oxygen concentrator and compressor that allows you to fill oxygen tanks at home. It is design for medical use, but I don't see why one couldn't use it to fill oxygen tank for aviation use. Maybe members working in the medical field familiar with similar equipment can shed some light on this. Having a hassle free way to refill oxygen tank, without renting big bottles and paying the $50 FBO charge sounds very appealing. What do I miss here?
Thank you,
