In response to the high demand for airtightness in high-end cleanrooms and GMP workshops, where traditional sealing gaskets are prone to aging and air leaks, Cleantop has developed the Gel Seal High-Efficiency Panel Filter. Utilizing a non-Newtonian fluid gel (gel sealant) for a 100% perfect seal, combined with a robust anodized aluminum alloy frame. This not only ensures continuous "zero leak" performance but also reliably intercepts submicron dust down to 0.1μm, making it the ultimate purification choice for semiconductor wafer manufacturing and biopharmaceuticals.

Utilizes a non-Newtonian fluid polyurethane gel to fill the frame, adapting tightly to the device's edge during installation. 100% avoids dust bypass leaks and passes even the most stringent PAO scanning leak tests.
The outer frame is made of corrosion-resistant anodized aluminum alloy, lightweight and sturdy. It provides both side gel slot and top gel slot designs that allow flexibility to adapt to various cleanroom ceiling grid systems and FFU fan filter unit structural requirements.
Features premium ultra-fine glass fiber filter paper, achieving filter efficiencies up to H13 to U15 (up to 99.9995% interception for 0.1μm particles). Ensures absolute cleanliness in industrial air supply, prevents micro-pollutants from affecting product yield, and meets the strict standards of pharmaceutical GMP and integrated circuit manufacturing.

Whether it’s the overall air supply construction of high-end semiconductor facilities or the regular maintenance and replacement of consumables for pharmaceutical workshops, Cleantop, with over 20 years of high-end air filtration R&D and manufacturing experience, will provide you with ultimate purification products that have passed rigorous PAO scanning tests.
Contact Engineering Team / Submit Project RequirementsThe Cleantop Gel Seal High-Efficiency Filter utilizes imported ultra-fine glass fiber filter paper, achieving a filtration efficiency of H13 (≥99.95%), H14 (≥99.995%), and U15/U16 (ULPA) levels for 0.3μm particles, which can be customized as per client requirements. The products are widely used in semiconductor wafer fabs, microelectronics cleanrooms, biopharmaceuticals, and other environments with strict cleanliness demands of ISO Class 1~5 (Class 100 to 10,000). The gel seal design effectively prevents side leakage and ensures the overall airtightness of the cleanroom.
The gel seal type employs a silicone or PU gel sealing structure, with the filter frame immersed in a groove filled with gel to form a continuous, seamless seal, providing reliability far superior to traditional EPDM gaskets. Its main advantages include: 1) Completely eliminates bypass leakage and ensures high cleanliness levels; 2) Resistant to vibration and temperature changes, offering a long service life; 3) Easy to maintain and replace without the need for bolted compression; 4) Especially suited for Class 100 and above ultra-cleanliness requirements in semiconductor FFU/DCC systems.
Cleantop has passed ISO 9001, ISO 14001, and ISO 45001 certifications and has recently obtained IATF16949 automotive industry certification and GMP certification for medical products in 2024. Products are certified by European BSC1, US EPA, NSF, and SOP, and comply with international HEPA filter standards EN 1822, IEST-RP-CC001, etc. Each filter undergoes MPPS scanning leak testing before leaving the factory and comes with an independent testing report, fully meeting the compliance procurement requirements of the semiconductor and microelectronics industries.
We offer comprehensive OEM/ODM customization services. With over 20 years of experience in filter R&D and manufacturing and a reserve of over a thousand solutions, we can customize according to customer requirements: 1) Dimensions (length, width, height, frame thickness); 2) Frame materials (aluminum alloy, galvanized steel, stainless steel, MDF, etc.); 3) Filter efficiency ratings (H13~U16); 4) Gel types (silicone/PU); 5) Separation methods (hot melt glue lines, aluminum dividers, paper dividers); 6) Brand logos, labels, and packaging. Our professional engineering team can provide drawing design and technical interface support.
Cleantop has a 50,000㎡ factory, with 20,000㎡ dedicated to six cleanrooms, where the gel seal high-efficiency filters are assembled in a Class 10,000 clean environment to avoid secondary contamination. The company has a national-level CNAS authenticated testing center equipped with professional equipment such as laser particle counters, scanning leak test benches, and aerosol generators, executing quality control across the entire process from raw material intake, filter paper pressure drop, glue line application, to machine scanning and packaging. Each product has a unique identification number for traceability of production batches and test data.
Under normal usage conditions (with upstream G4 pre-filter + F8 medium-efficiency pre-filter configurations), the service life of the gel seal high-efficiency filter typically ranges from 3 to 5 years, depending on the cleanliness of the cleanroom air, operational hours, and upstream pre-filter effectiveness. It is recommended to assess replacement timing by monitoring the final resistance: replace the filter once the actual resistance reaches twice the initial resistance or the design final resistance (usually 450~600Pa). We also offer filter life assessment and regular replacement service plans.
Standard specification products have a low minimum order quantity (MOQ), typically starting from 10 to 50 units; special specifications' MOQ is negotiated based on specific sizes and quantities.
