AndyFromCB Posted June 2, 2015 Report Posted June 2, 2015 I hate to bring this back from the dead and make a first post that's a plug but I was moved to finally join with this discussion found by a customer. Unfortunately (or fortunately, depending on how you look at it) the oxygen system described here is quite advanced and includes a lot of parts that make it expensive to repair or replace. It's always a tough pill to swallow when one expires. Please don't forget about the condition of the pressure reducing and altitude compensated regulators installed on these cylinders. So often, we find equipment that is severely out of spec. Merely replacing the cylinder without addressing the functional test/overhaul of the regulators is a mistake IMO. The OEM recommends an overhaul every 5 years, in fact. There are also cylinders out there not FAA-approved that will cause problems if your unit is ever sent to a qualified FAA repair station. The HRD cylinder mentioned here is an example of an approved cylinder, a good option. We offer a cylinder replacement with a new FAA-PMA approved unit, overhaul of the pressure reducing regulator, and functional test of the altitude compensated regulator for not much more than the cost of the cylinder mentioned here. This will be returned to you assembled, tested, leak checked, and ready to install. In any case, I'm here to help Brian Compressed Gas Systems, LLC FAA 2OXR299C EASA 145.6416 brian@cgs.aero Very good point. I did overhaul mine when I replaced my cylinder 4 years ago. What's the cost to overhaul? I paid about $600 to turbine rotables? Quote
Danb Posted June 2, 2015 Report Posted June 2, 2015 I have the same as Andy and replaced mine 3 yrs ago, at about 1800 also...I wonder if you mechanic incorrectly added a zero to $ 1300. 13,000 has to be a f.up....Mooneyspace is a great source of info..keep us posted btw I think I have Bravo #326. So that's more than 237... Quote
CGSLLC Posted June 2, 2015 Report Posted June 2, 2015 Very good point. I did overhaul mine when I replaced my cylinder 4 years ago. What's the cost to overhaul? I paid about $600 to turbine rotables? The cylinder is a little less than HRD, $1700.00 with 8130-3. The full service above, including new cylinder, overhaul, and functional test of alt. regulator is $2600.00 Next year, when your cylinder is due hydro testing, keep us in mind. We also functional test both regulators for $500.00 total. Again, it's a full service deal with 8130-3 cert. The functional test of the alt. regualtor is 1/2 the cost. It's hard to compete with a $40 hydro test from a welding shop but we're an FAA-approved repair station going though it per the CMM. Quote

So that's more than 237... It's probably not unreasonable if he's quoting a complete, factory new unit that's been stepped on by a few middlemen. There's "shops" out there that just farm out to repair stations like ours. Same thing goes for parts. The alt. regualtor alone is over $3k outright for an OH unit, for example. Quote
Bravoman Posted June 3, 2015 Report Posted June 3, 2015 They must have seen you coming! in 2013 I paid £2075 (about $3100 at today's exchange) for a new cylinder, rubber bands (mine were a bit sorry) and a regulator test/inspection (reseal), all with 8130 and EASA Form 1 - that was with Zodiac Aerospace in the UK Pretty similar experience with zodiac in 2013 as well. Their customer service here in the U.S. not so hot, but not horrible either. Quote
Bravoman Posted June 3, 2015 Report Posted June 3, 2015 Next time I will definitely give Brian at Compressed gas systems a call! Quote

You can get Mountain High at less than half the price) Cylinder bands/Clamps: 803272 Filling port: 26875 Cabin ports: 23599 Connectors for cabin ports: 8570 (standard) 802624 (for adjustable flowmeters) Maybe worth noting the $3000 odd price was for overhaul with new cylinder, the outright price was north of $8000 Any idea what the part number is and source for the boss seal between the tank and regulator?

Pictreed Posted July 7, 2016 Report Posted July 7, 2016 I'd like to start some research on Oxygen for the plane. -So not everyone is using medical oxygen? -Where would you get medical oxygen? -Is there somewhere that lists all the different types of adapters and what regulators to use? -What is the visual/hydro time for these tanks. I ASSume it's 6 years visual and 12 years hydro but that's extinguishers so I'm not sure. Thanks, Tim Quote
Marcopolo Posted July 7, 2016 Report Posted July 7, 2016 Pic, There is an add in the "parts for sale" forum by @smccray, he has some sort of 0xygen business he's trying to start, he may be of some assistance. RM Quote
Pictreed Posted July 7, 2016 Report Posted July 7, 2016 Thanks, I'll check it out. I posted this on the wrong thread, I'll try to find the other one. Sorry to have revived this one...go back to sleep. lol I'll post here http://mooneyspace.com/topic/17005-oxygen-system/#comment-243123 Tim Quote

Thanks, Tim Tim, I would think that trying to install a "built-in" O2 system would overwhelm virtually anyone, if they wanted to make it legal. If having your hangar elf do a built-in, I would find someone like me who has a system and copy that. I would be quite careful about W & B. I think probably Aerox has all the stuff you would need, especially if you decide on a portable system. I don't know anyone who uses medical O2. In today's world, all O2, medical, welding and aviation comes from the same manufacturers. Paying extra for anything other than welding O2, is a waste of money IMHO. I would have to look it up, but I think the requirement for inspection is 5 years for a hydro test, and a set tank replacement limit. (for my steel tank, it is 15 years) 1 Quote
Pictreed Posted July 7, 2016 Report Posted July 7, 2016 I found the 5 year bit on another thread so I think that's correct. I would have explained it was portable but the thread I MEANT to post it on (see link in my post above) was about portable systems so no worries. Tim Quote
Bob Posted July 7, 2016 Report Posted July 7, 2016 The hydrostatic test is a D.O.T requirement. The FAA requires us to follow the D.O.T. guidelines. Going by memory, my 77ft tank in my K is a 3HT tank. It is a thin wall, so the hydrostatic test is every 3 years and a service life of 24 years. Thicker wall tanks, that include scuba tanks are thicker and every 5. This link should help. http://www.c-f-c.com/gaslink/docs/dot_cylinder.htm Jerry also gives a nice rundown in this thread: Quote
