Why Does The Oxygen Concentrator Break Down If It Is Not Used For A Long Time?

1. The storage time is too long without moisture-proof measures

Now most of the lithium molecular sieves used in oxygen generators on the market, whether imported or 

domestic, have the disadvantage of being easily affected by moisture.

There are many days in southern China, and the weather may be humid for three months. When the weather 

is very humid and the oxygen generator is not working, the heat cannot help the molecular sieve to remove moisture.

Moisture-affected molecular sieves will solidify together, resulting in the failure of the molecular sieve's ability 

to produce oxygen.

It is recommended to use the oxygen concentrator several times a month.

2. The water vapor in the humidification cup flows countercurrently to the molecular sieve

The advantage of the humidification cup is that when the patient inhales oxygen, the oxygen is moistened 

through the humidification cup, and the patient breathes into the lungs more comfortably, but many people don't know it.

When the patient is not using the oxygen concentrator, from the perspective of molecular sieve maintenance, 

we recommend disconnecting the connection tube between the humidification cup and the oxygen generator.

Molecular Sieve Frequently Asked Questions

1. The front is damp, and if we continue to maintain it later, can the oxygen concentration of the molecular sieve go up?

Some friends may think that the oxygen concentration can return to the original oxygen concentration if it is 

damp in the early stage and maintained well in the later stage. This idea is not correct.

After the molecular sieve gets wet, it is an irreversible process. If it gets wet, it will fail, and the oxygen concentration 

cannot return to the original state, so the molecular sieve can only be replaced.

Can I buy molecular sieves and replace them myself?

Some customers feel that it is expensive to find a manufacturer to replace molecular sieves, and want to buy 

molecular sieves online by themselves.

We do not recommend customers to do this, because the brand, type and size of the molecular sieve you 

buy may not be suitable, and the sealing installation of the molecular sieve tank may not be qualified, resulting 

in the oxygen concentration still not reaching the standard. Professional work is entrusted to professional 

people, please contact the factory to purchase the corresponding accessories.
