E-Ox 640 Aviation Oxygen System

Extra Capacity for Long Trips or Frequent High Fliers
If you are flying frequent trips at altitude or taking extended cross country flights above 10,000 feet, the 640 system is just what you need. With 22.6 ft³ of capacity, you can easily see over 20 hours of oxygen when the system is used in conjunction with an Oxyimizer cannula. Even without an Oxymizer cannula, this cylinder will provide over 5 hours of continuous oxygen at 2 Liters per Minute (LPM). Maybe you already live at a high altitude, (like those of us here in Jackson Hole, WY), and find yourself always using oxygen whenever you fly - even on short trips. The E-Ox 640 is a good choice for this sort of application because the oxygen capacity means you won't be having to fill they cylinder as often as other systems. Measuring at 21.1” tall and 5.25” in diameter, the E-Ox 640 will fit comfortably in already cramped cockpits.

Simple to Use and Made to Last
The E-Ox 640 is about as simple as it gets but it’s extremely durable. The click-style adjustable regulator attaches to the cylinder and can easily be operated by one hand. The entire system is manufactured to endure the wear and tear of frequent use and is made to prevent leaks even when handled roughly. The regulator is adjustable in half-liter increments from 0 to 4 liters per minute (LPM)- more than enough to provide you with the amount of needed oxygen at almost any altitude. The cylinder itself is aluminum and can withstand being handled harshly but still remains lightweight. Each standard mask includes a 3-channel "pinch resistant" tubing and all of the components of the system - masks, cannulas, regulator, tubing, and the cylinder - are all medical grade components.

Includes Everything You Need
There is no need to worry about purchasing additional accessories for this system, everything you need is included:

• 1 - 22.6 ft³ (approx 640 liter) Aluminum oxygen cylinder
• 1 - CGA540 fill valve with shutoff handwheel and pressure gauge
• 1 - adjustable, click style regulator with half-liter increments from 0-4 LPM
• All necessary tubing
• At least one standard oxygen mask*

Upgrades and Options are Also Available
Each E-Ox Basic portable system can be configured in a number of different ways:

• Choose between 1 or 2 places to serve oxygen just to yourself or an additional passenger with a special "Y" adapter
• Select either basic oxygen masks (comes standard) or optional Oxymizer cannulas in either pendent or mustache style. Oxymizer cannulas can help you see a 4 fold improvement in oxygen use efficiency over a basic mask
• You can elect to have us pre-fill your cylinder with oxygen so that it is ready to fly as soon as it arrives at you door.
• Included a Respironics Go2 Pulse Oximeter with your system to get fast and accurate assessments of your oxygen needs, a helpful piece of information when setting oxygen flow rates

• Carbon Monoxide Detectors to warn you of engine exhaust leaks that could be filling your cabin with potentially lethal carbon monoxide.
• Pulse Oximeters to give you an objective assessment of your blood oxygen saturation - helpful in accurately setting oxygen flow rates
• Emergency Smoke Hoods to protect you and your passengers in the event of an in-flight fire
• Medical Supplies and Survival Gear to keep you prepared for the unexpected

Looking for a Multi-Passenger System with Greater Control?
If you are looking for a portable oxygen system that will accommodate up to 4 passengers and allows each user total control over their own flowrates, take a look at our E-Ox 640 Individual Flow Oxygen System. This system gives you the ability to quickly add or remove up to 4 users with quick-disconnect fittings and provides each user with their own adjustable flowmeter for enhanced oxygen flowrate control.

Important Note Regarding Shipping:
You may order your E-Ox oxygen cylinders shipped either pre-filled or empty. Pre-filled systems cannot be shipped by air due to federal hazardous materials regulations. Please understand that if you choose to have your bottle filled, we can only ship your order inside the US via USPS Parcel Post. If you do not select Parcel Post during checkout, there could be a delay in your order as we will contact you to correct the shipping. Shipping Parcel Post to Hawaii, Alaska or Puerto Rico can take up to and possibly exceeding 30 days.

Recommended Oxygen Flow Rates for Given Altitude

** FAA regulations state flow rate should be 1 Liter Per Minute (LPM) for every 10,000ft ASL with a standard O2 mask. An Oxymizer cannula reduces this flow rate by 1/2. The flow rates below have been rounded UP to correspond to the increments available on our adjustable regulators.
