To all users of dust collection equipment, are you troubled by pinholes? When pinholes occur in bag filters, dust leaks out, reducing dust collection efficiency. Many causes of pinholes are due to fireballs or sparks from welding coming into contact with the filter media, causing the synthetic fibers to instantly melt. Nakao Filter Industry Co., Ltd. has successfully developed a revolutionary filter cloth called "BOU," which reduces pinholes caused by thermal melting without compromising the inherent dust collection performance of the filter cloth by applying a special coating to it. 【Product Lineup】 ○ TR1555-BOU ○ TR15255UME-BOU ○ TR2027S-BOU For more details, please contact us or download the catalog.
