What Is a Gel sealing ULPA Air Filter?
Gel sealing technology involves creating a special liquid reservoir at the bottom of the filter frame, filled with a sealant. When the filter is installed, the bottom edge of the frame is immersed in the sealing liquid, creating a reliable seal that effectively prevents air leakage.
This design ensures a perfect seal between the filter and the mounting frame. Even with slight unevenness or vibration, the gel material adapts to form a sealing barrier, ensuring that filtration efficiency is not compromised due to sealing issues.
In recent years, the emergence of gel sealing technology has significantly improved the performance and reliability of ULPA filters. This innovative technology utilizes a liquid-seal design that maintains an excellent seal even after repeated assembly and disassembly or prolonged operation
Core Advantages
Excellent Sealing Performance
The tank adhesive offers excellent chemical stability, corrosion resistance, and mildew resistance, maintaining a strong seal even after repeated assembly and disassembly, and after prolonged periods of stagnant air.
Reduced Energy Consumption
Gel-sealed ULPA filters offer excellent pressure differential characteristics, reducing system energy consumption and ensuring more economical operation.
High Mechanical Stability
The proven thread structure ensures the filter's high mechanical stability, capable of withstanding the vibrations and pressure fluctuations found in industrial environments.
Excellent Weather Resistance
All components are constructed of materials with extremely low chemical volatility, meeting the requirements of conventional clean rooms and air filtration equipment, while maintaining stable performance in high-temperature and high-humidity environments.
Key Industrial Applications
Semiconductor and Electronics Manufacturing
In chip manufacturing plants, even nanometer sized particles can damage delicate electronic components. Gel sealing ULPA filters ensure ultra-high cleanliness in production environments, improving product yields.
01
Pharmaceutical and Biotechnology
In sterile pharmaceutical production plants and laboratories, these filters provide a highly clean air environment, preventing contamination from microorganisms and dust particles.
02
Healthcare Institutions
In hospital operating rooms and biosafety laboratories, ULPA filters provide sterile, clean air for surgery, reducing the risk of surgical infection and preventing the leakage of harmful microorganisms.
03
Aerospace
In clean rooms used for the assembly and testing of aerospace products, gel-sealed ULPA filters provide high-quality air filtration to meet the production environment requirements of high-precision, high-reliability products.

Gel Seal vs Traditional Seal: Technology Comparison
Eliminate the Risk of Micro Leakage
Traditional sealing methods (such as rubber gaskets or polyurethane seals) can cause micro-leakage due to material aging, frame deformation, or improper installation. Gel seals, on the other hand, provide a continuous, adaptive sealing interface that compensates for surface irregularities.
More Economical Operation
Gel seal systems have relatively low initial resistance, and resistance increases slowly over long-term use. This means that for the same air volume demand, using these filters can reduce ventilation system energy consumption.
Corrosion and Mildew Resistance
Furthermore, gel seal materials generally exhibit excellent chemical stability, resisting corrosion, mildew, and bacterial growth, which traditional sealing materials struggle to match.
How to Choose the Right Gel Sealing ULPA Filter
Efficiency Class
Select the appropriate efficiency class (U15-U17) based on the application environment.
01
Frame Material
Depending on the environmental corrosion requirements, choose a frame material such as aluminum, galvanized steel, or stainless steel.
02
Usage Environment
Consider temperature (up to 80°C) and humidity (up to 99% RH).
03
Dimensions
Ensure the filter size matches the existing mounting frame. Non-standard sizes can often be customized.
04
Certification Standards
Ensure the filter complies with relevant international standards, such as EN1822.
05
Installation and Maintenance Best Practices
Strict Pre-Installation Preparation
Before installation, thoroughly clean the duct work and ensure that airflow and room cleanliness meet certain requirements to extend filter life.
Standard High-Efficiency Pre-Filtration
To ensure the life of the gel-sealed ULPA filter, it is recommended that air be pre-filtered to a minimum of F8 (90%-95% colorimetrically) before entering the filter.
Regular Professional Leak Testing
Periodic leak testing is essential. Professional manufacturers typically leak test each filter within a strictly controlled cleanroom.
Conclusion
In summary, gel sealing ULPA air filters are an indispensable technology for industries demanding the highest air quality standards. Their superior filtration efficiency, reliable sealing, and energy-saving features make them an ideal solution for maintaining a clean, safe, and efficient industrial environment.
Whether you operate a clean room, pharmaceutical laboratory, or semiconductor production facility, investing in these filters will help improve air quality, protect workers, and increase overall operational efficiency.
