Product specs
Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Molecular Sieves. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
CMS-280 is a pellet-form carbon molecular sieve adsorbent intended for oxygen-nitrogen separation in PSA nitrogen generation systems. The listed standard pellet diameters are 1.0–1.3 mm and 1.3–1.5 mm.
Custom particle sizing is also described, so buyers should specify the required range rather than assuming every size is routinely available.
Supported specifications The stated bulk density is at least 660–670 kg/m³, particle strength is at least 85 N, compressive abrasion resistance is no more than 1%, and moisture content is no more than 0.5%. Standard packaging is listed as 20 kg square buckets, 40 kg round buckets, and 137 kg large drums.
Reported PSA test data At an adsorption pressure of 0.7 MPa, the performance table reports nitrogen purity and yield combinations of 99% at 320 L/(kg·h), 99.5% at 284 L/(kg·h), 99.9% at 203 L/(kg·h), 99.99% at 137 L/(kg·h), and 99.999% at 100 L/(kg·h).
These results are associated with an adsorption time of 45–50 seconds and pressure equalization of 1–2 seconds. The corresponding listed ratios are 1:2.4, 1:2.9, 1:3.8, 1:5.0, and 1:5.8. Procurement questions to confirm Performance in an operating PSA plant depends on equipment design and operating conditions.
Before purchasing, confirm the exact pellet-size tolerance, batch test method, bulk-density basis, strength test method, moisture limit at dispatch, and the convention used for the listed air-to-nitrogen ratios.
Buyers should also request performance data for their actual pressure, cycle timing, feed-air temperature, humidity, flow requirement, and target nitrogen purity.
Confirm the selected package type, net weight, sealing method, storage requirements, loading procedure, and whether a representative sample or batch certificate will be supplied.
Any service-life, maintenance, energy-saving, or application-specific performance expectation should be documented against agreed operating conditions before an order is finalized.
