carbon molecular sieve 300

Carbon molecular sieve is a kind of adsorption material with carbon as the main component and highly developed microporous structure, which is widely used in PSA nitrogen production and gas separation.

Carbon Molecular Sieve 300 (CMS 300) is an advanced adsorbent designed with a precisely controlled pore diameter of around 0.3–0.4 nanometers. This unique pore structure ensures rapid adsorption of oxygen while letting nitrogen pass through, making CMS 300 ideal for producing high-purity nitrogen in PSA systems. Its optimized pore distribution not only improves nitrogen yield but also extends the service life of the sieve under continuous operation.

Applications of carbon molecular sieve 300

Lithium Battery Production

CMS 300 delivers high-purity nitrogen that creates a dry, oxygen-free environment during battery assembly. This prevents electrode materials from reacting with moisture or oxygen, which can cause reduced capacity or safety risks. By ensuring moisture-free conditions, CMS 300 helps improve the consistency, safety, and cycle life of lithium batteries.

Food Cold Storage and Transportation

In refrigerated storage and long-distance transport, CMS 300 provides nitrogen atmospheres that replace oxygen inside containers and storage units. This slows down oxidation and microbial activity, keeping perishable goods such as meat, seafood, and fresh produce in optimal condition. Its stable nitrogen output ensures extended shelf life and consistent product freshness during distribution.

Medical Device Packaging

CMS 300 supplies controlled nitrogen environments for sterile packaging of medical instruments and devices. The oxygen-free atmosphere prevents material oxidation and microbial contamination, maintaining product sterility and integrity. This reliable nitrogen supply supports strict medical industry standards for safety and long-term storage stability.

Cosmetics Manufacturing

In cosmetics production, CMS 300 generates nitrogen to protect sensitive formulations during mixing, filling, and packaging. Nitrogen blanketing prevents oxidation of oils, active ingredients, and natural extracts, which helps preserve color, fragrance, and effectiveness. By maintaining product stability, CMS 300 ensures higher quality and longer shelf life of cosmetic products.

carbon molecular sieve300 FAQ

What is the lifespan of CMS 300?

YUANHAO’s CMS 300 typically offers a lifespan of 5–8 years, which is longer than the market average of 3–5 years. Its extended service life is achieved through high-quality raw materials, precise pore structure, and robust manufacturing. Proper maintenance, including air pre-filtration and regular regeneration, helps maintain performance and ensures reliable nitrogen purity over its entire service period.

How do I choose the right CMS model?

Selecting the correct carbon molecular sieve (CMS) requires careful consideration of nitrogen purity, flow rate, system conditions, and application requirements.

1.Nitrogen Purity Needs:

For standard nitrogen applications, lower-grade sieves such as CMS 220 or 240 may suffice.

For high-purity nitrogen above 99.9%, CMS 300 is ideal due to its optimized pore size and adsorption characteristics, ensuring stable and consistent output.

2.Flow Rate and System Capacity:

Determine the required nitrogen volume per hour. CMS 300 is suited for medium to high-flow systems that demand both high purity and substantial output.

3.Operating Conditions:

Evaluate the PSA system’s operating pressure, temperature, and air quality. CMS 300 performs reliably under typical industrial conditions but requires pre-treated compressed air to avoid damage from moisture, oil, or dust.

4.Application-Specific Considerations:

Consider the end-use of nitrogen. CMS 300 is particularly suitable for sensitive applications like lithium battery production, medical device packaging, food storage, and cosmetics manufacturing, where stability and product integrity are critical.

5.Supplier Consultation:

Engaging with a reputable supplier like YUANHAO allows for expert recommendations based on system parameters. They can help match the CMS model to your purity, flow, and operational requirements, ensuring optimal performance and extended service life.

Can CMS 300 handle high impurity air?

CMS 300 is sensitive to impurities such as oil, water, dust, and other contaminants in compressed air. Direct exposure to unfiltered air can clog pores, reduce adsorption capacity, and shorten its lifespan. To ensure optimal performance, air must be pre-treated using coalescing filters, dryers, and particle filters before entering the PSA system.

Proper pre-filtration protects CMS 300, maintains high nitrogen purity, and extends its operational life to the expected 5–8 years for YUANHAO products. Regular inspection and maintenance of pre-filters further safeguard the sieve’s performance under varying industrial conditions.

Is CMS 300 environmentally safe?

Yes. CMS 300 is chemically stable, non-toxic, and does not release harmful substances during normal operation. YUANHAO also adheres to environmental management standards (ISO 14001), ensuring production and disposal processes minimize environmental impact.

Does CMS 300 require special handling?

Yes. CMS 300 must be handled carefully to preserve its physical integrity and adsorption performance. Key handling practices include:

Avoid Dropping or Impact – Rough handling can crush or fracture the sieve granules, reducing surface area and adsorption efficiency.

Prevent Moisture Exposure – CMS 300 is highly sensitive to humidity. Always store it in sealed, dry containers and avoid contact with water or damp surfaces.

Protect from Dust and Contaminants – Keep the sieve away from oils, chemicals, or airborne particles that could block its micropores.

Use Proper Transfer Tools – When moving bulk quantities, use clean, dry scoops or containers. Avoid metal tools that may chip or damage the granules.

Maintain Storage Conditions – Store in a temperature-controlled environment away from direct sunlight and extreme temperatures to prevent structural or chemical degradation.

What pre-treatment is required before using the CMS 300 compressed air?

CMS 300 requires clean, dry, and oil-free compressed air to function effectively. Proper pre-treatment involves several steps:

Coalescing Filters – Remove oil, water, and large particles from the air stream. This prevents contamination that can block sieve pores and reduce adsorption efficiency.

Particulate Filters – Capture fine dust and solid particles down to 1 micron or smaller. This protects CMS 300 granules from abrasion and prolongs service life.

Air Dryers – Use refrigerated or desiccant dryers to reduce moisture content to very low dew points. Moisture can damage the sieve and lower nitrogen purity.

Pressure Regulation – Ensure the air enters the PSA system at the correct pressure, as excessive or fluctuating pressure can reduce adsorption performance and stress the sieve physically. The most suitable pressure environment for yuanhao cms 300 is 0.8Mpa

Regular Monitoring – Periodically inspect filters, dryers, and regulators to ensure consistent air quality. This maintains optimal nitrogen output and protects CMS 300 over its 5–8 year lifespan.
