The CAIRE SeQual Eclipse 5 is the clinical standard for dual-mode portable oxygen concentrators — the unit against which everything else in the category is measured. Six continuous flow settings from 0.5 to 3 LPM. Nine pulse settings. autoSAT technology that adjusts pulse delivery in real time to maintain consistent oxygen levels regardless of how your breathing changes. Works equally as a stationary home concentrator and a rolling portable. CAIRE was the first manufacturer to cover both the device and the sieve beds under the same 3-year warranty — a concrete financial difference over the life of the unit that most competitors do not match. FAA-approved.
Continuous flow 0.5-3 LPM + pulse dose settings 1-9. Prescription required — bring yours when you come in or call before ordering. In-stock units available at all five SW Florida showrooms.

Before you order — confirm these
The Eclipse 5 weighs 18.4 lbs with battery and cart — it is a rolling unit, not a shoulder-carry portable. It delivers continuous flow up to 3 LPM. If your prescription requires continuous flow and you want a wearable option up to 2 LPM, the Liberty2 may be more appropriate. Call us and we will help you compare. In SW Florida summer heat, plan for 70-75% of published battery runtime. 866-218-0902
Why the Eclipse 5 Is the Clinical Standard
One Device — Home and Portable · Eliminates Tanks Entirely
The Eclipse 5 works as a stationary home concentrator plugged into the wall and as a rolling portable on battery or DC car power. Plug it in at home, wheel it to the car, run on battery for appointments, recharge via DC while you drive. No separate home unit. No tank deliveries. No managing two devices. One setup, one service relationship, one device that does everything.
autoSAT Technology · 3 LPM Continuous · 9 Pulse Settings
autoSAT adjusts pulse bolus delivery in real time to maintain consistent oxygen saturation regardless of how your breathing rate changes — during a walk, a nap, or an anxious moment in a waiting room. Six continuous flow settings from 0.5 to 3 LPM. Nine pulse settings. The broadest prescription coverage of any portable we carry in a single device.
3-Year Sieve Bed Warranty — The One Most Competitors Skip
Every manufacturer warrants the device. Most exclude the sieve beds — the molecular columns that separate oxygen from air — which are among the most expensive components to replace. CAIRE warrants both the Eclipse 5 and its sieve beds for 3 years. Over a 5-year ownership period, that warranty difference is a real and significant cost distinction. It is not a marketing point — it is money.

Frequently Asked Questions
Both are dual-mode continuous flow portables delivering up to 3 LPM. The Eclipse 5 is the clinical standard with the longest track record in the category and the 3-year sieve bed warranty that covers the component most competitors exclude. The Independence is Made in the USA, carries a 5-year unit warranty, is CPAP/BiPAP compatible, and has a magnesium alloy frame. Neither is a compromise — they serve the same prescription range with different strengths. Come in and compare them side by side. 866-218-0902.
Yes — this is one of its defining advantages. The Eclipse 5 runs as a stationary home concentrator on AC power and as a rolling portable on battery or DC car power. Many patients eliminate their home concentrators and tank deliveries entirely. One device, plugged in at home, wheeled out for appointments. Our Respiratory Therapists can help you assess whether your prescription and living situation support making it your only device. 866-218-0902.
autoSAT is CAIRE's real-time pulse delivery adjustment technology. It monitors your breathing rate continuously and adjusts the bolus size and timing to maintain consistent oxygen saturation — not just at rest, but during activity, during sleep, and during any change in breathing pattern. Most pulse dose concentrators deliver a fixed bolus based on a set rate. autoSAT adapts. For patients with variable breathing patterns or activity levels, consistent saturation across conditions is a meaningful clinical difference. 866-218-0902.
Sieve beds are the molecular columns inside the concentrator that separate oxygen from air. They are consumable components with a finite lifespan — typically several years of regular use. Replacing them is one of the more significant maintenance costs in the life of a concentrator. Most manufacturers warrant the device but exclude the sieve beds, meaning when replacement is needed, that cost is yours. CAIRE covers both the Eclipse 5 and its sieve beds for 3 years. Over 5+ years of ownership, that difference adds up to real money. 866-218-0902.
Yes. Our 10-Day No-Risk Trial lets you take the Eclipse 5 home and use it in your actual life for 10 days. For larger equipment, call ahead and we can arrange delivery. If it is not the right fit, we will exchange it. No restocking fee, no fine print. 866-218-0902.

Overall very good product.
Style: 15" (2 x 2Ah)
I bought this trimmer as I had previously bought a Greenworks 24V MAX Cordless drill that uses the same battery.
The batteries to buy them alone are over 50 dollars each and as this has two its a great value in that respect.
I was tired of electric trimmers with cords or noisy gas powered ones that are hard to start.
This so far has worked excellent.
I have not had a problem with the trimmer cord breaking and having to re-wind it back onto the spool like some other trimmers I have used.
It is not noisy and it is effective and easy to use.
The only thing I would disagree on is it is advertised as having an Ultra lightweight design.
It is not heavy or cumbersome to use but I would not call it ultra lightweight.
Overall very good product.

Extremely diappointing
Style: 15" (2 x 2Ah)
I purchased a Greenworks Impact Wrench for my son. I was so so impressed with it that I purchased one for myself & decided to try their 2x24V 15" Cordless String Trimmer. Unfortunately just because a company makes one excellent tool doesn't mean that all their tools are good. The first problem I had with the trimmer was that it didn't come with the batteries or charger in the ad. It was supposed to have 4.0Ah batteries but came with 2.0Ah. In addition, more often than not, the manual didn't agree with actual parts & features. The trimmer requires two 24V batteries to operate. It can't be used with one battery even though it has a "low power" setting. On full power the trimmer had adequate power for most weeds but is no where near as powerful as a gas trimmer. The batteries only lasted about 20 minutes (this trimmer does not have a brushless motor). The 2 line feed head is not designed for easy reloading. In fact, it is the worst design I've ever owned. I've decided to return it & try one of their 2x24V brushless motor trimmers which should provide more power & has 4.0Ah batteries but costs significantly more.

CUSTOMER SERVICE IS TRASH - edited
Style: 15" (2 x 2Ah)
I bought this product and it arrived with one battery that doesn't charge out of the two. Without 2 batteries, it won't work at all. Attempted to contact Greenworks with the number Amazon provided. They were closed on the weekends. Called Monday and the message stated that customer support closed early. Attempted using the Chat option for help. It states the model number STE304, doesn't exist, so I couldn't proceed. Called on Tuesday. I have been on hold for over an hour and still nothing. Will update.
After about an hour and a half on hold (yes, the offer the option of leaving a call back number, which I didn't use as I had to work from home to access customer service when they were open. Also, they needed me to try out stuff with the batteries and give them serial numbers, etc.) The lady I spoke to spoke English and appeared to be US based. Eventually, after doing the "did you restart it" version of troubleshooting, it was indeed determined my battery didn't work and they offered to ship me a new one at no cost. I then had to dispose of my non-working battery in the proper manner, and our yearly toxic garbage pick up coincided with this, thankfully. It took time out of my work schedule to get this resolved, but the lady I spoke to was great and I did get my battery about a week or so later, which I did appreciate. Customer service needs better access esp since you have to have the physical batteries and charger to get this resolved, which you may not be able to do while working. Maybe they can't find people to work as that seems to be an issue everywhere. The weed eater works fine. Updated from one star to three based on resolving issues and a dead battery upon arrival, rather than the actual equipment working.

Style: 2 x 2.0Ah

Edged entire corner lot with a sidewalk on one charge of the batteries.
Style: 2 x 2.0Ah
Excellent. A bit heavier than my echo gas weed trimmer for reference. Fair balance but it is a bit of a workout. The good thing is I can edge a 10k sq ft corner lot in about 1/3 the time. On the corner, I have both sides of the sidewalk plus the curb side to do. I've owned gas edgers before also. This comes in comparable to the price I paid for one of those 20 years ago so I would also say a good if not very good value for the buck. It was not an initial edging but 1st maintenance for the year and rather overgrown. Didn't even use one full charge on the edger.
