Product Information

Kuraray’s activated carbon fiber delivers high surface area and excellent adsorption speed through its fibrous structure. It supports applications that are difficult for traditional granular activated carbon, particularly in gas and liquid purification. Its lightweight and flexible shape allows deployment in filters, textiles, industrial materials, and various other shapes and applications. The fiber structure also offers superior breathability and workability, making it a highly versatile adsorbent. Kuraray’s proprietary manufacturing technologies ensure both high performance and stable quality, providing next-generation adsorption solutions as an environment responsible material.

Activated carbon filter is a filter material that transform powdered activated carbon into high-density, high-strength molded shapes, combining design flexibility with stable adsorption performance. Their uniform molded structure maintains excellent fluid permeability and adsorption efficiency. Kuraray’s wet-molding technology uniformly disperses fine powdered activated carbon to produce long-lasting, high-performance adsorbents. As compact and efficient adsorption solutions, they are widely used in household water purifiers as well as environmental and industrial fields. For home water filter, we propose the optimal product based on target substances such as lead, trihalomethanes, musty odors, residual free chlorine, off-flavors, and PFAS.

Kuraray’s nitrogen gas generator adopts the PSA (Pressure Swing Adsorption) method to efficiently separate and supply high-purity nitrogen from ambient air. With high-performance activated carbon adsorbents (CMS; Carbon Molecular Sieves), the system provides stable nitrogen concentration and efficient operation. Its energy-saving design reduces operating costs, making it suitable for factories, research facilities, and food and pharmaceutical production. The system can be flexibly designed to meet application requirements, and maintenance after installation is straightforward. Leveraging Kuraray’s technical capabilities and reliability, the system offers a dependable long-term nitrogen generation solution. Kuraray is also among the few companies worldwide that manufacture both carbon molecular sieves (CMS) and nitrogen gas generator.

Kuraray Group provides not only activated carbon and filter products but also activated carbon adsorber vessels for water treatment. These vessels can be replaced in drum-unit scale, significantly reducing maintenance workload. They can also be introduced as test units, useful for performance verification and pre-installation evaluation.

Note: Availability of activated carbon adsorber vessels varies by country and region.
