CAIRE SeQual Eclipse 5 - Portable Oxygen Concentrator

Product Guide | Main Clinic Supply

Pulse Dose and Continuous Flow. One Portable Device. All-Day Versatility.

The CAIRE Eclipse 5 is one of the most versatile portable oxygen concentrators available today. It is one of the few portable units that delivers both pulse dose and continuous flow oxygen, which means it can meet almost any prescription a doctor writes. Whether you need oxygen only during activity, or you require a steady flow around the clock including during sleep, the Eclipse 5 can handle it.

At Main Clinic Supply, we have helped thousands of patients find the right portable concentrator over the past 14 years. The Eclipse 5 is a unit we recommend often to patients who have higher oxygen needs or who want a single device that works at home, in the car, and on airplanes. It is heavier than a lightweight pulse-dose-only unit, but the tradeoff is capability. No other portable in its class offers this range of delivery options in one device.

Overview of the CAIRE Eclipse 5

CAIRE Inc. has been manufacturing oxygen therapy equipment for more than 50 years. The Eclipse 5 is their flagship portable concentrator and is designed to function as both a travel device and a full-time home unit. It runs on AC power at home, on a 12V DC adapter in the car, and on a rechargeable battery when you are away from an outlet.

The defining feature of the Eclipse 5 is its dual-mode oxygen delivery. Most lightweight portable concentrators deliver only pulse dose oxygen, which works well for most patients during activity and rest. But patients who need continuous flow during sleep, or whose prescription specifies continuous flow oxygen, have traditionally needed a separate home concentrator. The Eclipse 5 eliminates that second device for many patients. It can sit on a nightstand running continuous flow at 2 LPM while plugged into the wall, and then go in its rolling cart the next morning for a day trip.

CAIRE Smart Dose Technology

Smart Dose is CAIRE's proprietary breath-detection and oxygen delivery system. It continuously monitors your breathing pattern and delivers a precisely timed pulse of oxygen at the very beginning of each inhale, the moment when your lungs are most ready to absorb it.

How Smart Dose Works

A pressure sensor inside the Eclipse 5 detects the slight drop in airway pressure that happens when you begin to inhale. The device responds within milliseconds by opening a valve and delivering the programmed pulse of oxygen. The pulse is delivered during the first third of your inhale, maximizing absorption efficiency.

This approach is more efficient than continuous flow in two important ways. First, it conserves oxygen by not delivering gas during exhale, when it cannot be absorbed. Second, it extends battery life significantly because the compressor works less. On a pulse-dose-only portable concentrator, Smart Dose technology is what allows a 4- to 6-pound device to provide clinically meaningful oxygen therapy. On the Eclipse 5, it provides the same efficiency benefit at higher flow settings.

Smart Dose and Sleep Use

One important consideration: Smart Dose pulse delivery requires that the device detect your breath. If your breathing rate drops significantly during sleep, or if you breathe through your mouth, some pulse-dose concentrators can miss breaths. CAIRE addresses this with a sensitive detection threshold, but patients who require nighttime oxygen are often better served by continuous flow mode on the Eclipse 5, which delivers oxygen regardless of breath detection. This is one reason the dual-mode capability of the Eclipse 5 is clinically important.

Oxygen Delivery Options

The Eclipse 5 covers a wide range of oxygen prescriptions. Here is what each delivery mode means for patients:

Pulse Dose Settings 1 Through 6

Pulse dose settings on the Eclipse 5 range from 1 (lowest) to 6 (highest). The setting number corresponds to the volume of oxygen delivered per pulse, in milliliters. Higher numbers mean more oxygen per breath. Most patients with mild to moderate COPD require pulse dose settings between 2 and 4 during activity. Settings 5 and 6 are for patients with higher oxygen needs. Your physician's prescription will specify which setting is appropriate for you.

Continuous Flow at 1, 2, and 3 LPM

Continuous flow mode delivers oxygen at a steady, uninterrupted rate measured in liters per minute (LPM). The Eclipse 5 offers continuous flow at 1, 2, and 3 LPM. This covers the majority of home oxygen prescriptions. Patients who require 4 LPM or higher continuous flow will need a higher-capacity stationary concentrator for home use; the Eclipse 5 would serve as a supplement for travel in those cases.

Battery and Power Options

The Eclipse 5 is designed to keep you powered through a full day of activity when used with the right battery strategy. It supports three power sources simultaneously and can switch between them without interrupting oxygen delivery.

Standard Battery

The standard battery that ships with the Eclipse 5 provides approximately 3 hours of run time on pulse dose setting 2. Battery life decreases at higher settings and on continuous flow mode. On continuous flow at 2 LPM, expect approximately 1.5 to 2 hours on the standard battery. 

Extended Battery

An extended battery is available separately and roughly doubles the run time of the standard battery. For patients who travel frequently or spend extended time away from outlets, the extended battery is a worthwhile investment. The Eclipse 5 can also charge one battery while running on the other, which allows continuous operation when AC or DC power is available.

AC Power (Home and Hotel Use)

The Eclipse 5 runs on AC power from 100V to 240V, which means it works on standard U.S. outlets and on international outlets with an appropriate plug adapter. You do not need a voltage converter. This makes it genuinely useful for international travel.

DC Power (Car and RV Use)

The included 12V DC power cord plugs into a standard car or truck power outlet. This allows the Eclipse 5 to run continuously during road trips without draining the battery. For patients who travel long distances by car, DC power is the most reliable way to maintain continuous oxygen access.

Flying with the CAIRE Eclipse 5

The CAIRE Eclipse 5 meets FAA acceptance criteria for use aboard commercial aircraft in the United States. This means it is on the FAA's approved list of portable oxygen concentrators that airlines are required to permit passengers to use in-flight.

Steps for Air Travel with the Eclipse 5

1. Notify your airline at least 48 hours before departure that you will be traveling with a portable oxygen concentrator. Most airlines require this by phone.
2. Obtain a letter from your prescribing physician stating that you require supplemental oxygen during flight, the prescribed flow setting, and confirming that the Eclipse 5 is your device.
3. Bring adequate battery capacity. FAA rules require batteries that last at least 150% of the total door-to-door flight time, including layovers.
4. Bring the FAA acceptance documentation that ships with the Eclipse 5 or print the current CAIRE FAA approval letter from CAIRE's website.
5. Arrive at the airport early. TSA screening of medical equipment can take additional time.

Who Is the CAIRE Eclipse 5 Right For?

The Eclipse 5 is not the lightest portable concentrator on the market. At 18.4 lbs with the rolling cart, it is heavier than pulse-dose-only units like the Inogen Rove 4 (2.8 lbs) or the Inogen Rove 6 (4.7 lbs). Before recommending the Eclipse 5, our specialists always ask: what does your prescription require?

The Eclipse 5 Is a Strong Match If You:

• Have a prescription that includes continuous flow oxygen, especially for nighttime use
• Want a single device that works as both a home concentrator and a travel unit
• Require pulse dose settings 5 or 6, which some lighter units do not offer
• Travel internationally and need worldwide AC compatibility
• Spend significant time in your car or RV and need reliable DC power operation
• Prefer not to manage a separate home concentrator and a separate travel device

You May Want to Consider a Lighter Unit If You:

• Only need pulse dose oxygen (settings 1–4) and never require continuous flow
• Walk frequently, shop, or travel on foot and want the lightest possible device
• Already have a home concentrator and only need a portable supplement

Our specialists are not insurance advisors, but we work with patients navigating Medicare oxygen coverage every day and can help you understand what questions to ask your plan administrator.

Routine Maintenance

The CAIRE Eclipse 5 requires minimal routine maintenance when used as directed. Keeping it clean and following a few basic habits will significantly extend its useful life.

Cleaning the Particle Filter

The Eclipse 5 draws room air through a particle filter before concentrating the oxygen. This filter collects dust and should be inspected and cleaned weekly if you live in a dusty environment, or monthly under typical home conditions. To clean it, remove the filter, rinse it gently under warm water, allow it to dry completely, and reinstall. Never reinstall a wet filter.

Cannula and Tubing

Replace your nasal cannula at least every two weeks under regular use. Bacteria and oils from skin accumulate in the cannula over time. Using a clean cannula reduces infection risk and ensures consistent oxygen delivery.

Battery Care

Do not leave the battery fully discharged for extended periods. If you will not be using the Eclipse 5 for more than two weeks, store the battery at approximately 50% charge in a cool, dry location. Avoid storing batteries in a hot car or in direct sunlight.

Professional Service

CAIRE recommends a professional service interval to verify oxygen purity, check all seals, and calibrate sensors. Main Clinic Supply's service center can perform this inspection. Contact us at 507-322-0247 to schedule.
