The "K-S Series" is a high-performance activated carbon deodorizer capable of removing odors with a single type of deodorizing agent against complex odor components. It decomposes odors with the powerful oxidative power of iodine. It contributes to the compactness of deodorization equipment and reduces maintenance costs. 【Features】 ■ Miniaturization: Filling volume is about half, and the equipment is also miniaturized ■ High cost performance: More economical the longer it is used ■ Long lifespan: High performance and long-lasting *For more details, please download the PDF or feel free to contact us.
