SeQual eQuinox (Pulse cum Continuous Flow)

Last year when SeQual launched Eclipse 5, it seemed like there could never be a better continuous flow POC but recently SeQual itself introduced a remarkable model eQuinox which is smaller and lighter version of Eclipse 5 with added features like Multi Language voice interface.

What you would like about SeQual eQuinox:

  • Adjustable Rise Time
  • Sensitivity adjustment
  • Can be used with CPAP/ Bi Level Devices
  • FAA approved – Approved for airplane use
  • LCD Screen displays estimated time left on the battery

What you won’t:

  • Low battery duration with default 12-cell battery when compared with competition


Compact machine with the dimensions of 13.6" H x 10.6" W x 7" D.

About 30% smaller than SeQual Eclipse.

SeQual eQuinox Size


Sequal eQuinox weighs 6.4 kg (14 lbs) with the 12 cell battery placed inside it.

The POC is:

  • 2.2 kg lighter than DeVilbissiGo
  • 2.6 kg lighter than Invacare Solo 2
  • 1.9 kg lighter than SeQual Eclipse
  • 2.0 kg heavier than Philips Respironics SimplyGo

SeQual has done an incredible job in retaining the features of Eclipse 5 in a much more compact body.


2 modes:

  • Continuous flow
  • Pulse (On demand) Flow

Continuous Flow

Provides Continuous flow from 0.5 LPM to 3 LPM with increments of 0.5.

Pulse Flow

SeQual eQuinox is the only POC in market which provides such a massive oxygen bolus. Its Pulse dose mode with 192 mL bolus is almost equivalent to the continuous flow of 7-8 LPM.

Bolus for Pulse Settings:

Setting 1 - 16 mL
Setting 2 - 32 mL
Setting 3 - 48 mL
Setting 4 - 64 mL
Setting 5 - 80 mL
Setting 6 - 96 mL
Setting 7 - 128 mL
Setting 8 - 160 mL
Setting 9 - 192 mL


A remarkable feature that eQuinox has retained from Eclipse 5 is the adjustable pulse trigger sensitivity.

The SeQual eQuinox provides 3 sensitivity settings ranging from 1-3 where patients making more efforts to breath can choose high sensitivity settings.

  • Mode of Operation- Continuous ‘C’ or Pulse ‘P
  • The flow setting
  • Estimated time left on the battery – a very useful feature.

autoSAT Technology

One of the best features by SeQual, autoSAT technology helps maintain a consistent FiO2 by servo-controlling the device to meet the changing respiratory rates of the patient.

Usually, a person needs more Oxygen while walking than at rest; this feature enables SeQual eQuinox to give more Oxygen per minute to the patient to maintain his SpO2 levels.

Rise Time

The machine has this advanced feature of adjusting the Rise Time (varying the delivery speed of bolus of Oxygen in pulse mode) to increase patient comfort.

3 settings:

  • Fast (Default)
  • Medium
  • Slow

This feature mainly determines how quickly a patient receives shot of Oxygen in every breath.


The machine has 2 LED indicators ; an LCD screen for visual indicationof alarms:

  • Yellow LED - Alert
  • Red LED – Alarm
Alarms in SeQual eQuinox
Alarm Type Visual Audible

Top 4 Oxygen Concentrators in SeQual eQuinox' competition

  1. DeVilbiss iGo
  2. SeQual Eclipse 5
  3. Invacare Solo2
  4. Philips Respironics SimplyGo

Top 3 comparison with SeQual eQuinox

  1. SeQual eQuinox v/s DeVilbiss iGo
  2. SeQual eQuinox v/s SeQual Eclipse 5 v/s Invacare Solo2
  3. SeQual eQuinox v/s Philips Respironics SimplyGo

Providing these features and specifications in one package seemed like a distant reality but SeQual has done it.

It would be extremely tough for other manufacturers to match the class of SeQual eQuinox as it is clearly the best continuous flow POC in the market.

Hi Duane, most distributors give 2 year warranty on SeQual eQuinox. Coming to your second question, we don't buy or sell oxygen concentrators.

Can you recommend authorized dealers for Airsep, Equinox (Chart) and Philips in Ahmedabad. Do these companies provide trial period for patients to identify right product?

Hi Ashutosh, you can use our Dealer Finder Tool to find oxygen concentrator dealers in Ahmedabad. Coming to your second question, companies do not provide oxygen concentrators for trial period but they do offer rental plan where you can rent the machine for one month and if you decide to purchase the machine they waive off the rent amount. Hope this helps!

Thanks for response. My father is in advance stage of COPD hence he needs Oxygen supply for most of the time for which we use cylinders at home. Now we need a machine which can make him really mobile so that he can move out of house a bit and walk around a bit and can travel by air or road in India without bothering about oxygen. Which POC will be fit for him, please suggest. He is 71 yrs.

What is your father's liters per minute (LPM) requirement of oxygen?
Replied on: 2017-05-11 at 23:42:15
He is usually at 2 LPM but sometime during exacerbation we have to increase it higher but that is usually for a brief while in 3 to 4 range.

SeQual eQuinox, Invacare solo2 and Devilbiss igo are good concentrators that will suit your need fine as they provide continuous flow upto 3 LPM and pulse flow upto 6 pulse setting.

SeQual Eclipse 5 works well with patients breathing irregularly and is a reliable machine too. Battery life is mentioned in this review, it depends on the flow the machine is operated in.

Hi John, make sure that your machine is in a well ventilated area having at least 3 inches between the back of the eQuinox and any obstructions (furniture, curtain, etc.). If the problem persists, contact your equipment provider.

Taiwan is a territory controlled by the Republic of China. Gaurav, if you have a budget of more than INR 45,000, then it is better to go for an manufacturer like AirSep, Philips Respironics, Nidek or Invacare and if you want a machine for less than Rs. 35,000 then Equinox would be a good option for you.

Just bought Eclipse 3 from friend, very limited use by previous owner, in excellent condition, some accessories not used. One spare battery still in cardboard box and plastic covering...part no. 1056,serial no. 113127494. Placed on charger and solid red light appeared. Any suggestions as to possible problem? If needs replacing what would cost be? Thank you.

Replied on: 2016-01-20 at 02:01:00
Hi Clayton, try using the spare battery to run the machine. If the problem persists, then would mean that the machine is experiencing system malfunction and you will have to contact the SeQual (now owned by Caire - Chart Industries) service centre.

What is the maximum duration (no of hours) that the machine can be used continuously to give oxygen?
Oxygen Times
Replied on: 2015-11-17 at 02:02:06
Hi John, there is no restriction from the manufacturer about the maximum number of hours that the machine can run continuously; but, the best practice is to give your POC some cool down time of about 20-30 minutes after every 8 hours of operation.
