How PSA Nitrogen Generation Works
CMS acts as the adsorbent in PSA separation beds, helping separate nitrogen and oxygen from air. The feed-air condition, equipment design and operating cycle form part of the material review.
01 · Compressed Air
Compressed air is the feed to the PSA system. Share the available pressure, temperature, moisture condition and existing filtration or drying arrangement. Reviewing feed preparation helps identify the conditions under which the CMS and nitrogen-generation equipment will operate.
02 · PSA Beds with CMS
CMS is packed inside the PSA separation beds. The grade, particle properties, bed arrangement and operating cycle need to be considered together. Compare model data at the stated pressure and test conditions rather than reviewing the material separately from the equipment.
03 · Nitrogen-Rich Gas
Nitrogen-rich gas is supplied for the specified process duty. Define the required purity or oxygen limit, delivery pressure, average flow and peak demand. Confirm the complete system’s operating point with Haina before applying published material data to a particular installation.

Review the application context and the operating information to share with Haina. Images illustrate application fields; they do not represent verified customer installations.
Industrial Gas Processing
Haina lists industrial gas processing among the application fields for its carbon molecular sieves. For a nitrogen-supply requirement, first define the downstream use, the required gas quality and the pattern of demand.
In a PSA nitrogen generator, CMS is the adsorbent inside the separation beds. Share the target nitrogen purity, required flow, feed-air quality, available pressure and operating cycle so that the material and system conditions can be reviewed together.
Foundry Industry
Haina identifies the foundry industry as an application field. Where a specified casting or metal-processing operation requires nitrogen or a protective atmosphere, the exact process step and gas specification need to be established first.
CMS belongs in the PSA nitrogen-generation beds; it is not a direct treatment for the casting process. Provide the required gas composition, demand profile, delivery pressure and relevant temperature or moisture conditions for an application discussion.
Electronics Industry
Haina lists electronics manufacturing among its application fields. A nitrogen inquiry should identify the particular manufacturing step and its permitted oxygen and moisture levels, rather than assuming that one gas specification covers the whole plant.
CMS can form the adsorption medium in a PSA nitrogen-generation system. Share the target purity, flow stability, pressure at the point of use, feed pretreatment and operating schedule. Suitability for the particular process must be confirmed with Haina.
Chemical Industry
Haina identifies chemical production as an application field for gas-separation materials. The inquiry should clarify whether the requirement is nitrogen generation, gas drying or removal of a specified impurity, because these duties can require different materials.
For PSA nitrogen generation, CMS is located in the separation beds. Provide the feed composition, impurities to be removed, product-gas requirement, flow, pressure and temperature, together with any process-compatibility constraints.
Oil & Gas / Oil Extraction
Oil extraction is one of Haina’s listed application fields. State the actual nitrogen or gas-treatment duty, the installation environment and the demand pattern before choosing a material grade. The industry name alone does not define the required specification.
Where nitrogen is produced by PSA, CMS is the adsorbent in the beds. Share feed-air quality, target gas composition, required flow, available pressure and site conditions. Any duty-specific pressure or gas-quality requirement needs separate confirmation.
Pharmaceutical Industry
Haina lists the pharmaceutical industry among its application fields. Identify the specific gas-supply or purification duty and clarify whether there are product-contact, documentation or site-quality requirements that affect material selection.
CMS is used in the adsorption beds of a PSA nitrogen-generation system. Provide the intended use, gas-quality specification, flow, pressure, feed conditions and any validation requirements. Suitability for a regulated or product-contact process must be confirmed rather than assumed.
Selection Guidance
These four items are a starting point for an inquiry. Final selection also requires the feed composition, process duty and equipment configuration.
Purity
State the target nitrogen purity or the impurity limit required at the point of use.
Flow Rate
Provide the required flow, peak demand and operating schedule, with the units and reference conditions.
Pressure
Share available feed pressure and required delivery pressure, including known operating variations.
Operating Conditions
Describe temperature, moisture, feed composition, pretreatment and the equipment cycle.
Technical Support
Technical information for a clearer material and application review. Share your process requirements, then confirm the relevant product data and handling guidance with Haina.
Any project-specific testing, sample evaluation or on-site service scope should be agreed directly with Haina.
Grade & Application Review
Discuss the process duty, target gas quality and operating requirements before choosing from the Haina material range.
Product Data & Specifications
Request the current model data sheet and confirm particle size, physical properties and the test conditions associated with published performance.
Operating Conditions
Share pressure, temperature, feed composition and the equipment cycle so the proposed material can be reviewed in its actual system context.
Feed Preparation
Describe the existing filtration and drying arrangement, together with known moisture or oil-carryover concerns relevant to the material review.
Storage & Loading Information
Ask for the applicable storage and filling instructions. Keep unopened material sealed and discuss the equipment supplier’s loading procedure before installation.
Existing-System Review
Provide operating history and changes in purity, flow or pressure. This information supports a focused discussion of the material and the surrounding process.

Need help choosing a CMS grade? Share your purity, flow and pressure requirements with our team.
What determines the right molecular sieve?
The process duty, feed composition, target gas quality and equipment conditions must be considered together. Provide the required purity, flow, pressure, temperature, pretreatment arrangement and cycle. Haina can then discuss the relevant material information and specification.
Can one grade cover every process?
No single grade should be assumed to suit every separation or drying duty. Haina’s range includes carbon molecular sieves and other adsorbents with different purposes. Confirm the intended duty and operating point before selecting or changing a material.
What does CMS do in a PSA nitrogen generator?
CMS is the adsorbent inside the PSA beds used for nitrogen–oxygen separation from air. It works as part of the complete system; feed preparation, vessel design, gas distribution and the operating cycle must also be considered.
What information should I send with an application inquiry?
Include the industry and process step, feed composition, desired gas specification, required flow and pressure, temperature, moisture conditions and operating schedule. For an existing unit, add the current grade and operating history.
Can the same performance figures be used for different systems?
Published product data should be read together with their stated test conditions. Do not transfer a purity, flow or consumption value to another system without checking the operating point. Ask Haina for current data relevant to the intended duty.
Can Haina confirm a pharmaceutical or product-contact application?
Send the intended use, required gas specification, documentation needs and site-quality requirements. Application-specific suitability and any regulated-use requirements must be reviewed with Haina; this page does not provide a qualification or performance guarantee.
