Technical principles and structure
Liquid Tank Seal
A chemically resistant liquid tank (typically made of PU) is integrated along the filter frame and consists of both side and top sections. This liquid tank seal ensures a secure and airtight connection between the customized gel sealing mini pleat ULPA air filter and the mounting frame.
01
Filter Media
High-efficiency filter media such as ultra-fine glass fiber filter paper or composite membranes (e.g., glass fiber substrate with a PTFE coating) are used. Glass fiber media are known for their low initial resistance and stable filtration efficiency.
02
Pleated Structure
The filter media typically adopt V-shaped or wave form pleats to maximize effective filtration area, enhance dust-holding capacity, and reduce pressure drop.
03
Frame Structure
The outer frame is made of aluminum, stainless steel, or galvanized steel, with thickness options that can be customized to fit different installation spaces.
04
Seal and Protective Mesh
To prevent media deformation and improve mechanical strength, protective metal mesh (such as diamond-shaped wire mesh) is added to both sides of the filter media. The frame edges feature a seamless sealing design to enhance overall sealing stability.
05
Application
Gel sealing mini pleat ULPA air filters are ideally suited for the following scenarios:
Cleanroom point-of-use filtration
such as pharmaceutical plants, biopharmaceutical sterile areas, and cleanroom air supply units (FFUs).
High-cleanliness equipment
terminal air outlets, FFUs, EFUs (equipment-side fan filter units), and similar applications.
High-requirement manufacturing
semiconductor, optoelectronics, LCD panel production, and precision electronic component manufacturing.
Medical and laboratory environments
biological laboratories, sterile operating rooms, and pharmaceutical production workshops.

Advantages
High Sealing Reliability
The liquid-sink seal provides a more stable and durable sealing structure, reducing the risk of leakage.
Its superior sealing performance helps maintain the cleanliness of cleanrooms and air supply terminals.
High-Efficiency Filtration Performance
Using ultra-high efficiency filter media (glass fiber or PTFE), it delivers filtration efficiency of up to 99.99% for particles as small as 0.12 μm.
The pleated media structure (V-shaped or corrugated) increases the filtration surface area, enhancing dust-holding capacity.
Low Pressure Drop
Optimized pleat design and high-quality filter media maintain low resistance even at high efficiency, helping reduce fan energy consumption.
A reasonable initial pressure drop provides greater flexibility in system design.
Long Service Life
The filter can capture more particles without sacrificing efficiency, reducing replacement frequency and maintenance costs.
The liquid-sink seal also reduces mechanical stress on the sealing area, minimizing leakage risks and extending overall service life.
Excellent Environmental Adaptability
Chemically resistant filter media and a corrosion-resistant frame make the filter suitable for various clean environments.
It maintains stable performance even under high humidity and high-temperature conditions.
Easy installation
Gel sealing mini pleat ULPA air filters made in china typically feature a modular design, making installation simple.
Replacement is also straightforward. Simply remove the old filter and handle it carefully; no complex pressure adjustments are required.
Quality and reliability assurance
Manufacturing Process
We employ processes such as pleated filter media fabrication, hot-melt adhesive bonding, and metal mesh reinforcement to ensure the stability and deformation resistance of the filter media structure.
Sealing Test
Before shipment, we conduct sealing tests such as PAO aerosol tests and concentration sampling tests to ensure that the leakage rate of each china gel sealing mini pleat ULPA air filter is within a controlled range.
Performance Verification
SYNRUI performs efficiency testing on every unit (such as MPPS testing and laser flow meter testing) to ensure that filtration performance meets the required standards.
Material Certification
SYNRUI can provide physical property reports or material inspection reports-such as temperature resistance and chemical resistance test reports-for filter media, frame materials, and the sealing liquid used in the tank.
Process Control
Our factory has established a strict quality management system (including ISO 9001 and cleanroom critical process control systems) to ensure consistent quality across all production batches.
