E-Ox 425 Aviation Oxygen System

Get Hours of Oxygen Without Cramping Your Cockpit
If you are regularly taking short trips at higher altitudes and usually only have yourself and maybe one passenger who need oxygen, the E-Ox 425 Basic Portable Oxygen System is just what you need. With an Oxymizer cannula, you can see up to 14 hours of oxygen with the 425 system without the bulk and weight of bigger systems - perfect for already tight cockpits. Even with just a standard oxygen mask, the 425 Basic system will provide a single user with 3.5 hours of oxygen. Measuring 21.4 inches tall (with regulator attached) and 4.4 inches in diameter, the E-Ox 425 will fit comfortably in many cockpits.

Simple to Use and Made to Last
The E-Ox 425 is about as simple as it gets yet is doesn't disappoint in durability. The click-style adjustable regulator is easily operated with even just one hand and attaches directly to the cylinder itself. It is manufactured to withstand the abuses of frequent use and designed 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 necessary oxygen at almost any altitude. The cylinder itself is aluminum and can take a beating but still remains lightweight. We intentionally keep a low stock in inventory to make sure each customer gets as new a cylinder as possible. 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 that are made to last.

Everything You Need is Included
There's no need to buy any additional accessories to get started with the E-Ox 425 basic aviation oxygen system. Each E-Ox 425 includes:

• 1 - 15 ft³ (approx 425 liter) aluminum oxygen cylinder
• 1 - CGA540 fill valve with shutoff handwheel and pressure gauge
• 1 - Adjustable, click-style regulator with 1/2 liter increments from 0.0 to 4.0 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.
• Have a Respironics Go2 Pulse Oximeter included to give you a fast and accurate assesment of you oxygen saturation - helpful for setting flow rates

• Carbon Monoxide Detectors to warn you of engine exhaust leaks that could be leaking potentially fatal carbon monoxide into the cabin
• Pulse Oximeters to provide an objective assessment of you blood oxygen saturation - a helpful piece of information when determining 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 425 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.
