FAQs

• When using an oxygen generator, do not use the oxygen generator near an open flame or while smoking.
• Pay attention to the oxygen concentration, and check your equipment regularly to see if there are any alarms to make sure you get enough oxygen. Too low oxygen concentration will affect the oxygen inhalation effect and the service life of the oxygen concentrator.
• If you need to use an oxygen concentrator due to chronic health problems, pay attention to monitoring the changes in your blood oxygen level at all times

Pulse flow: During use, it can automatically detect your breathing pressure, release the required oxygen in time when you breathe in, and stop working when you breathe out. Continuous flow releases oxygen regardless of whether it is inhaling or exhaling. At present, the pulse flow mode is mainly used in portable device, so that the use time of the machine is longer.

Generally speaking, the sound output of most oxygen concentrators ranges from about 30 decibels (DBA) to about 60 decibels. This is the volume of quiet conversations or quieter whispers. The VARON VP-01 has been tested and the sound is below 58 decibels. VARON VL-02 has been tested below 45 decibels.

Our Products are not FAA approved, we suggest you use it during the excursion.

A portable oxygen concentrator is a device that separates oxygen from the air and allows you to breathe in the oxygen on an as-needed basis. Portable oxygen concentrators can run on both AC and DC power, and they can be charged by both. This battery charge allows it to bring in air, separate the oxygen from the rest of the air, and deliver it back into your lungs at whatever rate is appropriate for you. Some portable oxygen concentrators offer both continuous flows and pulse dose settings.

The home oxygen concentrator is a device that converts air into oxygen, allowing you to breathe easier. It runs on AC power and is only compatible with home or stationary models. The concentrator brings air through the inlet vent into the machine, where it passes through a filter that catches dust and other small foreign particles before going through an oxygen separation system. The oxygen is then released through the tube and cannula in the proper dosage.
