Oxygens Technical Support
Before Requesting a Call-Out
We are available for technical support and are always happy to help. Many common chamber issues can usually be resolved quickly with simple guidance, meaning a call-out may not be necessary.
Please check the following common issues before requesting support. These checks help us resolve problems faster and may prevent unnecessary call-out charges or delays.
If you are unsure about anything, please contact us and we will guide you through the process safely.
Important: Always follow your chamber operating manual. Do not continue using the chamber if you believe there is a fault, damage, leak, or safety concern.
Troubleshooting FAQ
Select the issue below to jump straight to the relevant guidance.
1. Chamber is not pressurising
If the chamber is not building pressure, air is escaping from somewhere. This is usually caused by one of two simple issues:
A. The valve is not fully closed
Please check that the valve is fully closed. Depending on your chamber style, the valve may need to be screwed towards you or away from you.
- Turn the valve fully one way.
- Leave the chamber running for a couple of minutes.
- If pressure does not increase, turn the valve fully the opposite way.
- Leave it again for a couple of minutes and check the pressure response.
B. The zips are not fully closed
Each zip must be closed all the way to the very end. Even a small opening can prevent the chamber from pressurising correctly.
Important zip warning: If a zip is not fully closed, pressure on the open section can cause the zip to fail completely. It is essential that all zips are closed correctly to the very end. Damage caused by improper zip use is not covered under warranty.

2. Oxygen mask is not blowing oxygen
If you cannot feel oxygen coming through the mask, please check the following:
- Check that all oxygen tubing is connected securely.
- Check the pipe for kinks, bends, or restrictions.
- Test the pipe by gently squeezing the end of the tube. You should feel oxygen flow when the pipe is squeezed.
Please note that the oxygen tube is small, usually around 6 mm, so you will not feel a strong blast of oxygen. A flow of 10 litres per minute to the mask is suitable for therapy use.

3. The concentrator stops briefly then restarts
This is usually the thermal cut-out activating. It is a normal safety feature designed to protect the concentrator.
In most cases, the concentrator will pause for a short period and then restart automatically. This does not normally affect the session.

4. Not feeling enough oxygen through the mask
You will still receive oxygen benefit from being inside the chamber, as the chamber is constantly being filled and refreshed with ambient air.
The mask provides additional oxygen support. Because the tubing is small and the oxygen flow is controlled, it may not feel forceful, but the system is designed to provide appropriate oxygen flow during use.

5. The dial is not reaching 1.5 ATA
The inner dial may not always be the most reliable measure, as atmospheric conditions can affect the reading.
The outer dial reads the pressure inside the chamber. If the pressure valves are blowing, this indicates the chamber has reached the mechanical pressure setting, as the valves are set to activate at the required pressure.
What to check:
- Check that the chamber is fully sealed.
- Check the valve is fully closed.
- Check all zips are fully closed to the end.
- Check whether the pressure valves are blowing.

6. The chamber feels hot during use
The chamber pressurises using ambient room air. If the room itself is warm, the chamber interior will naturally feel warmer during operation.
The concentrator continuously filters and processes air during use, which can slightly increase the air temperature inside the chamber, particularly during longer sessions or warm weather.
To help keep the chamber cooler:
- Always use the chamber in a well-ventilated room.
- Keep a window open where possible.
- Avoid placing the chamber near radiators, heaters, conservatories, or direct sunlight.
- On particularly hot days, avoid using the chamber during peak daytime temperatures.
- Where possible, use the chamber earlier in the morning or later in the evening.
If additional cooling is required, a simple portable air conditioning or cooling unit positioned near the concentrator can help provide cooler intake air into the chamber during warmer weather.
Portable cooling units are not supplied by us, however many customers find them useful during hotter periods.
