An Oxygen System Consists of 4 Primary Components:
A cylinder, a pressure regulator, a flow control device, and a delivery mechanism (like a cannula or a mask.)
Choose a Cylinder
Choosing the right cylinder is a cost-benefit calculation of size, weight, capacity, and cost.
Pick the Right Pressure Regulator
Make sure it fits your bottle. Make sure it fits your needs.
What’s a Pressure Regulator?
A pressure regulator typically sits on top of your cylinder, though there are exceptions. As their name suggests, regulators “regulate” the pressure of the outgoing oxygen from a cylinder, both reducing the pressure and keeping it from fluctuating. Having a controlled and constant pressure is critical in an oxygen system.
CGA-540 vs DIN-477 (US vs European)
When talking about cylinders and regulators, you might run into the terms “CGA-540” and “DIN-477” connector types, which is referring to the size and threading of the valve on the top of the cylinder. CGA-540 is the standard in the US and Canada, while DIN-477 is the German standard used in Europe and elsewhere. For a regulator, valve and cylinder to fit each other, they need to match.
1-port vs 4-port
Regulators come in 1-port and 4-port options. A single-port regulator is suitable for most systems. Four port regulators are designed to connect a cylinder to more than one EDS pulse-demand device (which we’ll talk more about in a moment) and/or constant-flow station. A 4-port regulator automatically seals unused ports, which is why you don’t see a 2-port or 3-port regulator option—it is 4 regulators in one. Also, with a 4-port regulator, you can connect both an EDS pulse-demand device and a constant-flow station to the same cylinder.
Thinking of using an EDS? Use a Mountain High Regulator
When using a Mountain High pulse-demand oxygen delivery system, your regulator must deliver oxygen between 15-25 psig, for this reason we recommend using Mountain High regulators which are specifically designed for use with our EDS pulse-demand systems. The good news: All our regulators are compatible. If you buy a constant-flow system now and decide to upgrade to and EDS system later, you can use the same regulator.
Choosing the Right Fitting
You’ll need to connect your regulator to the flow control device, so your fittings and connectors will need to match up. If you have any questions, give us a call. We also have ready-to-go-systems so you don’t need to worry about your devices not connecting.
For built-in systems to connect to an EDS system, an inline, reducing regulator is required. This connects to the onboard oxygen supply and reduces the pressure so that it meets the pressure requirements of the EDS.
Choose Masks and/or Cannulas
Mount your Cylinder
Here are some quick solutions to mount your cylinder in your aircraft:
The Simple Option: A Complete Oxygen System
Get everything you need in a complete system
If you want things even simpler, we’ve taken the confusion out of oxygen systems by creating complete systems with everything you need to fly. The kits below include everything you’ll need in a system and will still allow you to choose your cylinder size and some other options (depending on the kit).
