13X-HP Molecular Sieve for PSA Oxygen Generator


With the popularization of small household oxygen concentrators, more and more customers are faced with the problem of how to choose their own suitable molecular sieve products and get into trouble when replacing molecular sieve. There are many types of oxygen-making molecular sieves on the market, with different quality. Many people do not know which indicators and data to pay attention to when selecting molecular sieves. Which indicators of molecular sieve directly affect the quality and service life of molecular sieve gas production

The main principle of PSA oxygen production is that the air flows through the molecular sieve, the gas penetrates the pore of the molecular sieve, and the nitrogen is absorbed preferentially by the molecular sieve. So the oxygen is enriched. In order to evaluate the oxygen enrichment capability of molecular sieves per unit weight, there are two indexes to explain the oxygen enrichment capability of molecular sieves: one is the oxygen-nitrogen separation ratio (dimensionless) , and generally, the oxygen-nitrogen separation ratio is more than 3.0. The higher the better, of course. The other is oxygen

what’s 13x-HP molecular sieve?

This article will list 13X-HP molecular sieve for oxygen generation.

13X-HP molecular sieve is a new type X molecular sieve, which is mainly used in the pressure swing adsorption oxygen production process of pressure adsorption. JALON JLOX-500 series PSA high-efficiency oxygen-enriched molecular sieve, and JLOX-101A PSA/VPSA lithium-based oxygen molecular sieve, three high-quality hot-selling products on the market for a detailed introduction and description.

13X-HP molecular sieve designed generators:

  1. – Smaller and lighter with the same oxygen output as a larger PSA O2 HP molecular sieve design.
  2. – Reduced energy, airflow, and sieve usage per volume of oxygen.


13X-HP adsorbent’s superior performance is directly related to its enhanced N2/O2, selectivity relative to PSA O2 HP adsorbent.

JLOX-500 series high-efficiency oxygen molecular sieve is an oxygen molecular sieve developed by JALON company with similar performance to 13XHP.

It is a new type X molecular sieve, which is mainly used in the pressure swing adsorption oxygen production process of pressure adsorption and atmospheric desorption. It has high nitrogen adsorption capacity and excellent nitrogen and oxygen separation coefficient.

JLOX-500 series molecular sieve is mainly used in PSA oxygen generators for the generation of high purity oxygen with the advantages of faster adsorption rate, higher oxygen production rate, and longer useful life. It is the substitute of 5A (CaA) type molecular sieve.

JLOX-500 molecular sieve is specifically designed for industrial and medical oxygen generators.

JLOX-501 molecular sieve is for portable oxygen generator.

JLOX-100 series oxygen enrichment molecular sieve are the lithium form aluminosilicate with X type crystal structure. Compared with JLOX-500 series molecular sieves, JLOX-100 series molecular sieves have better nitrogen and oxygen separation coefficient and adsorption performance. And JLOX-100 series molecular sieves have a specially developed and designed molecular sieve for oxygen production from the air with an international advanced level.


JLOX-100 series oxygen enrichment molecular sieve is mainly used in PSA oxygen concentrator device, with the characteristics of higher N2 adsorption capacity and N2 with 02 selectivity, easy desorption and etc. Its N2  adsorption capacity is 2-3 times larger than A-type oxygen enrichment molecular sieve, while the 02 and N2 selectivity is about twice of A type oxygen enrichment molecular sieve, at the same time, it has good wear resistance and longer service life. So, it can significantly increase the economic benefits of oxygen production by lowering operating costs and energy consumption.

Both JLOX-101(A) and JLOX-501(A)have a high nitrogen capacity and superior nitrogen/oxygen selectivity compared to equivalent products in the market that result in the use of significantly less material relative to other molecular sieve adsorbents without sacrificing oxygen throughput or purity.

Through the above comparison, how to choose which model of molecular sieve has been very clear. What suits you is the best. For example, if you are a user of a small household oxygen generator, you can choose JLOX-101 oxygen molecular sieve when you are pursuing a longer life of oxygen molecular sieve. Because it can have the advantages of low molecular sieve loading and high oxygen production concentration and high abrasion resistance.

►What is the difference of the Li X molecular Sieve & molecular sieve 13X-HP

—Li X N2 adsorption capacity is 2-3 times larger than normal type oxygen enrichment molecular sieve bed. At the same time, it has good wear resistance and longer service life.

►What about the N2/O2 Selectivity of Li X molecular sieve

—N2/O3 measured: 6.3
