KLC Mini-pleat Filter VS KLC Separator Filter, which is the "optimal solution" for your cleanroom?

April 07, 2026

The structural form of high-efficiency filters directly affects the spatial layout, operational energy consumption, and maintenance cycle of a cleanroom. Based on years of industry experience, KLC provides two mature solutions—filters with and without partitions—to help you make the optimal choice according to actual operating conditions.

KLC Separator Filter

Using aluminum foil or coated paper as separators, a deep filter paper air channel is formed. This traditional structure provides the product with high structural strength and dust-holding capacity. KLC's partitioned products perform steadily when handling high airflow and high-concentration dust environments and exhibit excellent high-temperature and high-humidity resistance. They are highly suitable for installation in the high-efficiency sections of large central air handling units (AHUs) or for industrial dust collection scenarios with strict mechanical strength requirements.

KLC Mini-pleat Filter

The ultrafine and dense folding of filter paper has been achieved using hot melt adhesive technology. Compared with traditional products, the KLC Mini-pleat Filter series maintains the same filtration efficiency while having a thickness of only about half that of a Separator Filter and a significantly reduced weight. This lightweight and thin design can effectively save valuable ceiling space in cleanrooms and reduce the load on FFU fans. At the same time, the KLC Mini-pleat Filter offers more uniform airflow distribution and a high degree of production automation, making it the preferred choice for terminal air supply in cleanrooms, laminar flow hoods, and space-constrained scenarios.

Selection Decision Recommendation

If your project seeks optimal space utilization and low operating resistance, the KLC Mini-pleat Filter is the best solution; if the working conditions are harsh, with large air volume or requiring high-temperature and high-humidity resistance, the KLC Separator Filter will provide more reliable protection. KLC always provides customized air filtration solutions based on your on-site requirements.
