Product Description

The SeQual Eclipse 3 portable oxygen concentrator is one of the most reliable pulse dose and continuous flow units in a 24 hour, 7 days a week package. It’s the one unit for both ambulatory and stationary oxygen needs. The Eclipse separates oxygen from ambient air. First the air is filtered and separated into nitrogen and oxygen, and then the nitrogen is eliminated. This cycle then concentrates the oxygen and delivers it to you.

Eclipse 3 can operate in both Pulse Dose and Continuous Flow Modes. It operates in Pulse Dose or Continuous Flow Modes. In Pulse Dose Mode, oxygen is supplied in a burst at the beginning of each inspiration, providing a selectable range setting of 16 to 192 mL. In Continuous Flow Mode, the oxygen is provided at a constant flow rate between 0.5 and 3.0 liters per minute.

The battery life can last for up to 3 hours (depending on setting) and can be charged while in use. The unit can operate on either internal rechargeable battery power or an external power source. It includes a Smart Battery charger that recharges the internal battery whenever the unit is connected to any external power source.

It features an easy to transport cart with an effortless telescoping handle to transport the unit over even the toughest terrain. This is one of the most user-friendly portable concentrators available today. It also comes bundled with a variety of accessories to help support the active lifestyle, including a accessory bag and cart.

The SeQual Eclipse is approved by the FAA (Federal Aviation Administration) for use during flights on most major airlines. You can also use it on buses, trains, cruise ships and boats.

Don’t be tied down to oxygen tanks or large home concentrators. Get your freedom back!

The SeQual Eclipse Starter Package includes the Eclipse unit, one rechargeable battery, AC and DC adapters, cart, accessory bag, cannula and manual. Please view our different Eclipse Packages if you require more batteries or accessories.

"Disappointed in the Eclipse" SeQual Eclipse 3 Portable Concentrator

Review by on September 2, 2015

I have had an (actually 3) unit and have not had one yet that would charge in the car without bl;owing the fuses. This is in 3 different vehicles, a van, an suv and an RV. The batteries last 20 to 30 minutes which is way less than it says in the hype for it. I am on o2 24/7 at 3 liters and this will not work at 3 if plugged into the car, it automatically goes to 2L. I can do the 2 in the car if I am not moving around.

"A little noisy on highest setting" SeQual Eclipse 3 Portable Concentrator

Review by on July 11, 2013

It makes sense that it's louder on the highest setting, but it was annoying me a little at first. I got used to that, though. In every other way, it's a great portable concentrator and I'm satisfied with it.

"Can't believe how small" SeQual Eclipse 3 Portable Concentrator

Review by on July 2, 2013

I pictured this concentrator being a lot bigger when I saw it on the website but that was deceiving! I decided to wear it on my back, instead of the cart all the time. Not too bad!

I've actually had my Sequal Eclipse 3 for a year now, and it feels like this thing just won't quit. Everything is still working great. The battery is still going strong even though I use it a lot.

Product Questions & Answers

How to change filter on the SeQual Eclipse 3?
The SeQual Eclipse 3 has a washable/external filter and an internal filter that need to be maintained. The washable/external filter is located on the back side of the machine just below the carry handle and is a mesh square filter. The gross particle filter should be rinsed off and completely dry before placing back into the machine. Depending on the number of hours the machine is used each day, the internal filter should be replaced every 1-2 years.

How do I perform a hard reset on the SeQual eclipse 3?
To perform a hard reset, you will need to first remove the battery from the machine and disconnect all power to the unit. Let the machine sit powered down for 2 minutes. Plug the machine back into AC power (the power supply for use in the home) WITHOUT BATTERIES and turn the machine on. Once the unit has been running for 5-10 minutes, place the battery into the machine WHILE RUNNING. This should eliminate the issue the machine is having. If the issue still occurs, call us and we will begin the process of creating a case.

How loud is the SeQual Eclipse 3?
This unit is 48 decibels on a setting of 2. This is equivalent to the noise level in an average home.
