ADSORBENT FOR AIR SEPARATION
Oxygen molecular sieve for PSA, VPSA and concentrators
Oxygen molecular sieve supplier for PSA generators, VPSA plants and oxygen concentrators. Compare NaX, 13X-HP and Li-LSX grades, particle size, samples, MOQ and packaging.
Quick answer
XIAOYOU supplies zeolite grades used to adsorb nitrogen from air in oxygen concentrators, PSA generators and VPSA plants. Start the selection with the equipment, oxygen purity, flow, cycle and approved original adsorbent—not the product name alone.
Oxygen sieve families and specifications to confirm
| Item | What to verify |
|---|---|
| NaX / 13X | Common sodium zeolite direction for compatible PSA equipment; confirm exchange level, nitrogen capacity, shape and particle size. |
| 13X-HP | Higher-performance family that must be compared with the approved reference and a representative operating cycle. |
| Li-LSX | Lithium-exchanged zeolite for high-productivity or compact-bed designs; equipment-specific validation is required. |
| Particle size | Spheres or beads selected for column geometry, valve protection, pressure drop, mass-transfer rate and dust retention. |
| Key properties | Nitrogen capacity and selectivity, bulk density, delivered moisture, crush strength and attrition. |
| Packaging | Moisture-barrier bag or drum, net weight, closure, palletization and lot identification. |
How to compare suppliers
- Identify the equipment manufacturer, model and PSA, VPSA or concentrator technology.
- Send oxygen purity, flow, pressure or vacuum, cycle and current performance.
- Keep the approved grade, shape and particle size unless a replacement is validated.
- Compare TDS and COA values using equivalent test methods.
- Define the sample protocol, duration and acceptance criteria before testing.
- Compare the same quantity, packaging barrier, documentation, Incoterm and destination.
Select by equipment type
PSA oxygen generator
Provide flow, purity, pressure, cycle, bed dimensions and feed-air quality.
VPSA oxygen plant
Provide capacity, pressure and vacuum, recovery, vessel volume and installed reference.
Bed replacement
Check moisture, oil, valves, leaks and the analyzer before attributing a performance loss to the adsorbent.
Sodium or lithium: no universal grade
NaX, 13X-HP and Li-LSX respond differently to partial pressure, cycle timing, bed volume and ambient conditions. A higher laboratory capacity does not guarantee a direct replacement in an existing machine. Validate the identified grade in a representative cycle.
Protect the sieve from moisture
Zeolite begins adsorbing water vapor as soon as the package is opened. Prepare the columns, tools and loading team before opening. Feed air must be free of liquid water, oil and particles to protect the new charge.
The sample must represent commercial supply
Define the same grade family, particle size, packaging and delivery condition for the sample and the order. Record the loading mass, initial performance and test method so a successful sample can be compared with the commercial lot.

Frequently asked questions
Which molecular sieve is used for oxygen generation?
Depending on the equipment and cycle, approved NaX, 13X-HP, Li-LSX or other oxygen-selective zeolite grades may be used to adsorb nitrogen from air.
Is Li-LSX always better than 13X?
No. Lithium grades can improve productivity in suitable designs, but bed size, pressure, cycle, energy use, cost and the approved equipment specification determine the right choice.
Can the same grade be used in PSA, VPSA and oxygen concentrators?
Not automatically. Pressure, vacuum level, cycle speed, bed geometry, recovery target and particle-size restrictions differ between systems.
What oxygen purity can the molecular sieve produce?
Purity depends on the complete system, including feed-air treatment, compressor, valves, beds, cycle, flow rate and ambient conditions. The adsorbent cannot compensate for equipment faults.
Can I request a sample?
Yes. Send the target grade, particle size, quantity, equipment, test protocol, acceptance criteria and destination so the sample represents the intended commercial supply.
What information is needed for a quotation?
