MOLECULAR SIEVE
CMS-330 Carbon Molecular Sieve
CMS-330 is a Haina carbon molecular sieve grade for nitrogen generation. At 99.5% purity and the published test conditions, its table lists nitrogen yield of at least 330 L/kg·h.
| Model | CMS-330 |
| Diameter | 1.0–1.2 mm |
| Particle Strength | ≥95 N |
| Standard Packaging | 20, 40 or 137 kg/drum |
Product Overview
Haina specifies a 1.0–1.2 mm diameter, bulk density of at least 670 kg/m³ and particle strength of at least 95 N. The performance table provides purity points up to 99.999%.
Applications
Discuss this grade when evaluating PSA nitrogen-generation output, purity and air demand. The stated pressure and cycle conditions should be considered together with the equipment requirements.

Nitrogen-Output Data
The published table includes grade-specific nitrogen-yield values.
Particle Strength
Haina lists a minimum particle strength of 95 N for this grade.
Process Evaluation
Review purity and air demand at a consistent operating point.
Storage & Selection
What information is needed to select CMS-330?
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.
