MOLECULAR SIEVE
CMS-260 Carbon Molecular Sieve
CMS-260 is a non-polar carbon adsorbent for separating nitrogen from air by pressure swing adsorption. Haina describes this grade as a material for nitrogen-enriched gas production with high oxygen-adsorption capacity.
| Model | CMS-260 |
| Diameter | 1.0–1.3 mm |
| Bulk Density | 650–670 kg/m³ |
| Standard Packaging | 20, 40 or 137 kg/drum |
Product Overview
The original page highlights nitrogen-generation efficiency and low air consumption, particularly in the 99.5% to 99.9% purity range. Its performance table provides additional purity points at the stated test pressure.
Applications
Haina lists large-scale air-separation nitrogen equipment and uses in coal mining, shipping, and petroleum storage and transport. Match the grade to the required purity and actual PSA conditions.

Storage & Selection
What information is needed to select CMS-260?
Please provide the feed-gas composition, desired product purity, required flow rate, operating pressure and temperature, plus the equipment configuration and cycle. For an existing system, include its current material grade and operating results. These details help Haina discuss a grade under comparable conditions.
How should I compare product specifications?
Compare values at the same test conditions and purity target. Particle size, bulk density and mechanical properties also matter to the vessel and process. The data on this page are a selection reference; request the current specification and confirm the relevant operating point before ordering.
How should unopened and unused material be stored?
Keep containers tightly sealed and dry. Prepare the equipment before opening a package, minimize exposure to humid air, and promptly reseal any unused material. Follow the product-specific storage instructions supplied with the order.
What should be checked before changing the adsorbent?
Identify the cause of the performance change first. Review feed pretreatment, moisture and oil carryover, filtration, pressure stability and the equipment cycle. Share the operating history with Haina so material selection can be discussed together with the condition of the system.
Does adding more CMS always improve nitrogen production?
No. Bed quantity must match vessel design, packing density, gas distribution and the PSA cycle. Uneven loading or localized high-velocity flow can reduce performance and damage particles. Follow the equipment supplier’s approved filling and commissioning procedure.
