rhys 0 #1 April 8, 2011 We have been using our oxygen system for 3 months, I was sent a bunch of components from mountain high and assembeled them as best I could think of at the time. We have to avoid screwing or riviting as our plane/s are part 135 and that is a mod. So I have adhered an aluminium T extrusion on the window sill and mounted the components on that. I have ordered some more components and hose so I can tidy it all up and some magnets to clip the hoses and masks to after use via some steel adhered to the hose connection. I don't have a good photo here but you can kinda see it in the photo on this page; http://www.facebook.com/pieces/posts/10150551552220304#!/photo.php?fbid=491171536602&set=t.100001357592431&theater I'll post a better photo later. I am interested to see anybody elses set up... I am basically starting again routing the ports to where I want them and have a fair idea of what I want to do to make it safer and tidier,ut would like to get some inspiration from others.. any clever cookies out there with a smart looking setup.

billvon 3,008 #3 April 8, 2011 For a fullface mask for 30K+ applications this looks like it has some potential (attached.) To the original question, one suggestion I would have is to avoid plastic and nylon as much as possible. It's hard to avoid in the final stage (i.e. cannula) but earlier on in the system, try to avoid things like PVC manifolds. PVC is not normally flammable, but in pure oxygen it's _very_ flammable. Copper tubing works OK. Quote Share this post Link to post Share on other sites

I am using what mountain high oxygen supply me only, I am sure they would not be selling these components if they were not suitable?"When the power of love overcomes the love of power, then the world will see peace." - 'Jimi' Hendrix Quote Share this post Link to post Share on other sites

I hate to say it but the best source for help would be someone with the CAA, or is it JAA in New Zealand. Anyway, it never hurts to give them a call to ask their advice or opinion. As far as the stuff from MHO, I've used the PVC tubing for 24 place and 19 place O2 systems, (Skyvan, T Otter & Caravan). Never had any issues once the bugs were worked out. The biggest was good flow to the rear seats. Ended up using 2 feeds per side, one for the front seats, one for the rear. The problem with the PVC tubing is 1) The FAA is not familiar with it. Remember that MHO does not sell TSOd or approved equipment. Yes, it's good stuff. 2) For a permanent install the FAA likes to see copper tubing. The main reason being that a ridged tube can not be pinched. Was not able to open your attachment. Can you attach another picture and I'll take a look. Sorry, its been 4 years since I've had to set up an O2 system, so I have no pics to supply. Quote Share this post Link to post Share on other sites

To put 6 people up at 30,000 feet you are looking a thousands of dollars if you do it right. There was a time that I was going above 25,000 feet about once a week. It sucks.

Anyway, it never hurts to give them a call to ask their advice or opinion. It is the NZCAA, and I did call them 6 months ago when I was purchasing the system, and unfortunately in this age of accountability and litigation nobody was willing to give me a definitive answer of what we required, I called the CAA twice and they told me to contact an engineer and ensure the engineer was happy, the engineers did not know but could install a perminent system for $15,000, I called an aircraft manufacturer (PAC) and everybody wanted to help but could not give me a definitive answer on the requirements of a portable system. It turns out if we use a portable system, it is secure and we do not screw, rivit or alter the airframe in anyway while abiding by our part 149 regulations, then we are fine. That is covered, I am simply wishing to tidy up the system, it works well but it just looks a bit scruffy in the airplane, and there is a possiblity of a snag hazard. I do have a good idea of what I am going to do and have ordered the parts. I will post better photos of our current system and I will also post photos of the new setup once I have finished..."When the power of love overcomes the love of power, then the world will see peace." - 'Jimi' Hendrix Quote Share this post Link to post Share on other sites
