Medium-efficiency bag filters serve as the core intermediate filtration component in industrial ventilation, fresh air purification for central air conditioning, and factory air filtration systems. They directly determine the downstream clean-room load and the overall air filtration quality of the ventilation system, making them widely suitable for various industrial production, commercial building, and general purification applications.

Leveraging years of R&D experience in filtration materials, KLC has developed a new bag filter featuring high dust-holding capacity and high filtration efficiency. Moving away from the conventional structure of PP melt-blown fabric combined with polyester non-woven fabric, this product utilizes a proprietary high-performance nanofiber bag material. This addresses the industry-wide challenge of efficiency plummeting after electrostatic discharge (ESD) at the core fabric level. It delivers stable, authentic, and compliant filtration performance, fully meeting ISO 16890 standardized testing requirements and high-standard industrial filtration needs.

KLC nanofiber filter bags eliminate reliance on electrostatic charge. Even under ISO 16890 electrostatic discharge testing conditions, they consistently maintain a minimum filtration efficiency of ePM10 50%. This thoroughly resolves the common industry issue of "inflated efficiency ratings due to static charge versus poor performance after discharge." The test data is authentic and reliable, fully complying with official testing standards.

Utilizing advanced nanofiber forming technology, the product offers significantly upgraded filtration precision. It achieves graded filtration performance—ePM1 50%, ePM2.5 60%, and up to ePM1 70%—delivering vastly improved capture capabilities for fine particulate matter compared to traditional medium-efficiency filters. It effectively captures airborne fine dust and suspended particles, significantly reducing the dust load on downstream high-efficiency filters, extending the service life of the entire filtration system, and ensuring long-term, stable operation of the ventilation system.

While achieving high filtration efficiency, the product retains excellent dust-holding characteristics. Its high capacity and slow clogging rate effectively extend the filter replacement cycle, thereby reducing equipment maintenance costs and the frequency of replacements. The product structure is designed for standard intermediate filtration applications in central air conditioning and industrial ventilation systems. It offers excellent installation compatibility, allowing for performance upgrades to legacy systems without requiring structural modifications, and easily solves common problems associated with traditional filters, such as substandard efficiency, failure to pass inspections, and poor purification results. From material innovation to performance upgrades, and from regulatory compliance to long-term operational reliability, KLC’s high-dust-holding, high-efficiency bag filters utilize core nanofiber technology to break through the performance limitations of traditional medium-efficiency filters. Backed by consistent, verified filtration data and compliant product quality, they provide reliable intermediate-stage filtration for diverse industrial ventilation and air purification systems, ensuring efficient and compliant operations across various industries.
