Oxygen Tank for Schleicher ASW 27 or 28

[Discus 44[_2_]]

I am looking for a replacement Qxygen cylinder for my ASW 28. It is the weird one almost the same size as a "D" bottle but smaller in diameter 4.125 inches and 16.5 inches long. Mine is stamped DOT-3AA2015 REE16.6 Which is the cubic ft capacity.

The luxfer M15A (OS415T)advertised here will fit.

I've not tried it, but this looks possible.

Check with Williams Soaring Center. Rex usually stocks steel tanks that will fit.

Scott, do you have any input on the Luxfer carbon composite cylinders working in aviation use, i.e. gliders? They appear to be medical O2 bottles, but I don't know if that makes a difference. The dimensions of the OS415T, at 4" diameter, just could work in my LS-4. I'm searching for a light-weight bottle.

Best Regards,

Todd

I believe (not claiming divine awareness)General Aviation O2 cylinders used in the U.S. are regulated by the U.S. Department of transportation. if you buy or use a cylinder the responsible authority is D.O.T, I have bought and used these Luxfer cylinders in my glider after passing a hydro test. these luxfer cylinders are amazingly light and have a reasonable capacity. the downside is the 15 year max life. check with your A.I. or A&P (standard or experimental)
I'm holding one in my hand filled to 2200 psi, it weighs 4 lbs 3.9 ounces
Good luck

Eastern Sailplane used to always have a stock of )2 cylinders that fit. Have you tried Eastern or Williams?

That was many years ago. The steel D and E cylinders are no longer in production.

At the end of 2013 when purchasing a steel D for the 29 from Wings and Wheels, Matt did not have stock and had Aerox get in touch directly. At that time Aerox claimed to have very little demand for the steel D and were selling their last few. 7T may have got the last one.

Perhaps others who have 27s with modified baggage compartments to fit an AL-682 (E), can document them in more detail than I did on the ASW27 newsgroup. An AL-415 (D) would be even easier to fit.
There are at least two 27s with this mod.
With the O2 cylinder in the top of the fuselage behind the air extractor, the factory O2 cylinder area can be lined with a PVC pipe or similar and used for other storage.

Another 29 I get to fly has a composite cylinder in the normal O2 mount. That cylinder is quite small, besides having a short life limit. An instant but more expensive option.

Three years ago I did get a brand new steel D from Eastern. The composite cylinder is too small for western flying.

luxfer 'd' composite, 15 year life, under $300, available, 15.4 cubic ft.
1.2 cubic ft smaller than a steel 'd',
so it is about 7% smaller,
weighs 5 lbs full
and it will physically fit. These numbers are for the luxfer M15A5.

I'm sure there are even smaller composite cylinders out there. but why?
