These days a lot of folks seem to be using EDS systems which seem to offer very good efficiency at turning *pressurized gas into blood oxygen. So less pressurized gas is needed than back in the old days when we were all using surplus A8A regulators. This webpage lists what seem to be the the standard O2 cylinder sizes these days: http://www.mhoxygen.com/index.php?op...ew=article&id=... The cylinder sizes I generally see referred to in forums like these are these medical sizes: D-size: 4.4 in/11.1 cm diameter, 18.7 in/47.4 cm length, 14.7 ft^3 volume JD-size: 5.3 in/13.3 cm diameter, 18.1 in/46.0 cm length, 22.8 ft^3 volume E-size: 4.4 in/11.1 cm diameter, 27.0 in/68.6 cm length, 24.1 ft^3 volume The information I'm looking to collect is, what size cylinder do you actually have installed, and does it generally meet your needs? Thanks, Bob K.http://www.hpaircraft.com/hp-24 EDS system. AL415 bottle secured to the forward lift tube. Brad Tetra-15- Hide quoted text - - Show quoted text - Brad, What size is that?? *I've been looking for days on various sites for a new cylinder, and I've *concluded that each VENDOR comes up with their own 'standard' for naming the cylinders. *I was thrilled to note that the cylinder in the Janus C was an enormous 39 Cubic Feet, and crushed when I found it was the special thin wall steel cylinder with a limited life, which had expired NINE YEARS AGO. Hey Jim, here are the specs from Richards website: EDS System W/Aluminum AL-415 14.6 Cu. Ft. Cylinder 4.375" Dia X18.65" Weight 6.25 Lbs. Brad |
