FAQs About Stationary Oxygen Concentrators

What is a stationary oxygen concentrator?

A stationary oxygen concentrator is designed to stay in one place and provide a reliable oxygen supply whenever it’s needed. Most people use it as their primary home oxygen system, rather than something they move or carry regularly.

It’s built for consistency and ease of use, making it well suited to daily routines where oxygen support is required for long periods.

Who is a stationary concentrator best suited for?

Stationary concentrators are often chosen by people who:

Use oxygen for much of the day or overnight
Prefer a simple, plug-in setup without managing batteries
Spend most of their time at homeWant a system that runs quietly and predictably in the background

They’re also commonly chosen when oxygen therapy becomes part of a long-term routine rather than something used occasionally.

Do stationary oxygen concentrators run continuously?

Yes. Stationary units are designed to operate for extended periods, including continuous use when required. They’re built to support daily and overnight oxygen needs without regular interruptions. As they run on mains power, there’s no need to monitor battery levels or charging cycles.

Are stationary oxygen concentrators noisy?

Stationary oxygen concentrators are designed for indoor living spaces, which means keeping noise to a minimum is an important consideration.

While no oxygen concentrator is completely silent, modern stationary units are engineered to operate quietly enough for use in bedrooms and shared areas, including overnight use, without becoming a constant distraction.

How do I choose between a stationary and transportable device?

The choice often comes down to how much you move around during the day.

If your oxygen use is mostly at home and required for long periods, a stationary concentrator may be the most practical option. Whereas, if you need higher flow but still want to move the device between rooms or take it with you occasionally, a transportable unit may be worth considering.

New Advanced & Ultra Quiet VSD Compressor

Traditional oxygen concentrators run at full power constantly, producing maximum output even when only a portion is needed—wasting energy in the process. The Kingon stationary unit features a variable-speed drive (VSD) compressor that intelligently adjusts motor speed to match the required oxygen flow. This means quieter operation, lower power consumption, less heat, and greater efficiency without compromising performance.

Humidifier Bottle To Prevent Dryness

The P2-O5E supports the use of a humidifier bottle, which adds moisture to the oxygen to help prevent dryness and irritation during therapy. Ideal for long-term use, this feature soothes the nasal passages and throat, keeps airways hydrated, and promotes easier, more comfortable breathing.

Quiet. Efficient. Built for Everyday Home Use.

Kingon stationary oxygen concentrators are designed to function quietly and efficiently in ordinary home settings, such as bedrooms and shared living spaces.

For people who rely on oxygen during the day or overnight, this means fewer distractions, less background noise, and a system that functions well without drawing attention to itself.

~31 dB at 2 LPM (library ambience) and ~37.5 dB at 5 LPM (light rainfall)
P2-SOC operates up to ~10 dB quieter than typical stationary oxygen concentrators
Continuous 24/7 operation
Lower standby power (<10W)
Reduced running cost over time

Smarter Oxygen Compression for Long-Term Home Use

Kingon stationary oxygen concentrators use a variable-speed drive (VSD) compressor that automatically adjusts its speed based on demand.

This means quieter operation at lower flow settings, improved energy efficiency, and more consistent oxygen delivery over time. Even as internal components naturally age.

For people relying on oxygen day after day, this technology helps support reliability, comfort, lower partner disturbance and long-term performance.

Continuous Flow Oxygen for Everyday Living

Kingon stationary oxygen concentrators deliver continuous-flow oxygen, supplying a steady and reliable output at the selected flow rate.

Oxygen Concentration 90%-3%/+6% at all settings
Continuous flow provides oxygen at a constant rate, regardless of breathing pattern, making it suitable for rest, sleep, and prolonged daily use.
Because oxygen is delivered continuously, it does not rely on breath detection. Which is an important consideration during sleep or shallow breathing.
Continuous-flow oxygen is a well-established delivery method commonly recommended for long-term, home-based oxygen therapy.

Stationary vs Transportable Oxygen Concentrators

Choosing between stationary and transportable devices often comes down to mobility needs and daily usage.

Stationary Oxygen Concentrators

Designed to stay in one location
Continuous-flow oxygen only
Ideal for long-term, home-based therapy

Transportable Oxygen Concentrators

Offer more mobility to run errands like going to the doctors or friends
Can be repositioned or transported when needed
Suitable for users who want flexibility beyond one room

Just wanted to say a big thanks. The unit has arrived this morning and its a brilliant bit of kit and so easy for mum at 85 to manage. Excellent service

I learned that the Kingon is the lightest weight portable oxygen concentrator approved by both the FDA and FCC. This meant that I could use it on an airplane. Prior to getting this unit I was instrumental to take at least SIX bottles of oxygen with me to ensure I didn’t run out. In other words, I would constantly have to walk back to our vehicle and switch tanks. Instead I was able to take my Kingon, power cords, and extra battery to meet my needs. Because you are able to use the Kingon even as it charges I kept mine plugged into the cigarette lighter of our vehicle e route to the festivities. This meant that my unit was fully charged when we arrived at the venue. I was receiving such a great supply of oxygen that I didn’t rush to reconnect to my home unit as I sat visiting with my family. Suddenly my son spoke up saying he thought that my colouring was better and I was breathing easier on my portable unit than when I used the big concentrator. The oxygen from my new Kingon seem more pure and I found that I didn’t feel as short of breath. If you depend on a machine like I do you understand just what a blessing this is! I no longer have to worry about losing my independence because the Kingon will allow me to remain active as well as independent. If you are considering obtaining a portable device be sure to check this one out!
