What is SeQual Eclipse 5 Portable Oxygen Concentrator?

The SeQual Eclipse 5 portable oxygen concentrator is one of the most popular POCs in the market. It delivers adequate oxygen on its continuous and pulse dose settings to meet the patient's respiratory requirements. Its autoSAT technology also enables the machine to produce a consistent pulse dose volume depending on the breath rate changes.

This machine is highly recommendable for people suffering from sleep apnea, COPD, and other respiratory diseases. Since it can also work with CPAP and BiPAP machines, undergoing such additional therapy is not a problem. Moreover, its wide range of accessories and travel approvals will allow you to use it everywhere.

How Does SeQual Eclipse 5 Portable Oxygen Concentrator Work?

The SeQual Eclipse 5 has a passive system for separating oxygen from the air. First, the air flows into the POC. The filtering process begins, and it will then enter the compressor.

The pressurized air goes into the ATF concentrator module, where it becomes separate nitrogen and oxygen contents. The POC then uses its rotary valve system for the air separation process. It forces the air through a series of several pressurized sieve beds.

The adsorbent material in the POC collects the nitrogen molecules through the "vacuum pressure swing adsorption" process. It will also purify these molecules using a vacuum pressure cycle. Then, it forces the concentrated oxygen through a sieve bed into the tank.

The oxygen flows from the tank through a HEPA filter and sensor, measuring its flow and concentration. A flow control valve will then manage the oxygen flow to the oxygen patient. After that, the cycle repeats from the start.

SeQual Eclipse 5 Portable Oxygen Concentrator Features

SeQual has been a consistent leader in continuous flow portable oxygen concentrators, providing the safest oxygen delivery for patients. Its recent release is the SeQual Eclipse 5 portable oxygen concentrator. You can check its features below to know more.


Even though it looks bulky, you will never feel awkward bringing the SeQual Eclipse 5 because it has a compact design and minimalist colors. Its cart makes the unit look better and aesthetically pleasing.

Size and Weight

The SeQual Eclipse 5 oxygen concentrator can be heavier and bulkier than other POCs. The portable unit weighs 15 pounds, while its power cartridge weighs 3.4 pounds. On the other hand, its dimensions are 19.3 inches high, 12.3 inches wide, and 7.1 inches deep.


This portable oxygen concentrator can weigh heavier than other machines. However, you can still use it easily because its cart allows you to move the unit everywhere. It may not be the most portable oxygen concentrator, but it is not the heaviest either.

LCD Screen

SeQual Eclipse 5 has an easy-to-read LCD screen. It usually displays the following:

Flow Setting Indicator

The flow setting indicator is one of the essential things in your POC. This part usually displays the set prescribed flow for your pulse dose setting (mL) or continuous flow mode (LPM). The previous set flow will continue at start-up every time you turn on the device.

Power Cartridge Status Gauge

The power cartridge status gauge shows the remaining charge in the battery. You may see five horizontal gray bars that represent 20% of the total battery charge.

These charge indicator bars will most likely blink when charging the battery. On the other hand, the power cartridge status gauge will not light up or flash on and off if you do not install the battery correctly.

External Power Indicator

The external power indicator will appear on the user control panel when you plug the SeQual Eclipse 5 and use the AC or DC power supply.

The SeQual Eclipse 5 has a few controls in the control panel, and you don’t have to worry because you can learn them quickly. We have listed them below to help you understand their meaning and how to use them.

On and Off Button

Clicking this button will power the unit on or off. You may notice a green light indicator near the button, which signals that you have turned the device on and it is working correctly.

Increase or Decrease Flow Setting Buttons

You can use these buttons to adjust the flow to your prescribed setting.

Delivery Mode Button and Indicator

You can use this button to toggle between the pulse dose and continuous flow mode. The former will activate the autoSAT technology and allow an increase in the usage time while powered by the battery.

The green pulse dose mode indicator will light up when you activate the pulse dose mode. Consequently, the machine will deliver oxygen depending on the breath rate.


When something goes wrong with your portable oxygen concentrator, it will give off alarms that require immediate action. Some instances where an alarm goes on are the following:

  • Low oxygen output
  • Unit malfunction
  • Oxygen flow outside normal limits
  • Low power cartridge or a warm power cartridge
  • Loss of power or hot power cartridge
  • Low 9V battery

Sound Level

Like most POCs, the SeQual Eclipse 5 is also quiet, guaranteeing a peaceful and noise-free sleep during nighttime. It exudes a noise level of 48 dbA when operating its continuous flow setting at 3.0 LPM. Its 3.0 pulse dose gives off a 40 dbA noise.

SeQual Eclipse 5 also makes noise for its alarms. In this case, it emits fewer than 57 decibels of noise.


SeQual Eclipse 5 has a power cartridge as its battery. This power cartridge usually contains lithium-ion battery cells. It allows you to use it without AC or DC power sources.  

You can charge this power cartridge in two different ways. First, you can place it in the POC and connect it to an AC or DC power source. On the other hand, you can also put the cartridge in an optional desktop charger.

SeQual Eclipse 5 may operate through an AC or DC power supply. The AC power supply can accept 100-240VAC, 50/60 Hz, and deliver up to 200W of 28VDC output.

Meanwhile, the DC power supply is for DC accessory outlets, like those found in vehicles. Its input voltage is 11.5-16 VDC and can deliver up to 150W of 26VDC output.

Power Consumption

This portable unit only consumes nominal power. You can ensure the machine does not take too much electricity when operating and charging. However, the power consumption still depends on the setting, power source, and activity.

  • 0.5 LPM Continuous Flow – 48 watts
  • 3 LPM Continuous Flow – 145 watts
  • 1.0 Pulse Dose Setting – 45 watts
  • 6.0 Pulse Dose Setting – 95 watts
  • Battery Charging – 50 watts

Flow Type

If you are looking for a POC that supports both continuous and pulse flow settings, you may check out the SeQual Eclipse 5 because they have both features. You can also use this machine with CPAP and BiPAP machines for those with sleep apnea disorder.

Sieve Beds

The SeQual Eclipse 5 contains ATF sieve beds for air and nitrogen separation. These sieve beds force the collected nitrogen molecules to go to the product tank. Moreover, it helps the machine get the oxygen for oxygen patients. 

Fortunately, you can replace your sieve beds regularly because you can find lots of them in different stores.

Warm-Up Time

Warming up will not take too much time because the SeQual Eclipse 5 only takes 2 minutes before getting warmed up.

Oxygen Concentration

The SeQual Eclipse 5 has an oxygen concentration of 87 to 95.6%. It also has a continuous flow accuracy of +/-10% or 200 mL/min.


The SeQual Eclipse 5's capacity differs depending on the flow setting. For instance, the pulse dose setting ranges from 1.0 (16 mL) to 9.0 (192 mL). Meanwhile, the continuous flow can be 0.5 to 3.0 LPM.


The SeQual Eclipse 5 has an air inlet filter on the device's top rear. The air from the surroundings usually gets inside the machine through it. It filters out the unnecessary dust or particles that may come with the air. 

However, this air inlet filter needs replacement every year. It will require frequent replacement if you use it in a dusty environment. Cleaning is also a must to keep your portable unit performing correctly.
