String Filter Cartridge Application
Integrated Design with Perfluorinated Material
The filter membrane, support layer, central rod, and connectors are all constructed entirely of PFA/PTFE material, with no non-fluorinated materials in contact with the medium. It can withstand various corrosive media such as strong acids, strong alkalis, and strong oxidizing solvents, and is suitable for high-temperature conditions up to 190℃, fundamentally avoiding the risk of contamination caused by material corrosion. Simultaneously, it strictly controls cleanliness indicators: metal leaching ≤25ppb/tube, TOC residue ≤10ppb, and 0.2μm particle residue ≤15 particles/10mL, fully meeting the stringent purity requirements of high-purity processes such as electronic and pharmaceutical grades, eliminating secondary contamination.
High Dirt Holding Capacity and Long Lifespan Structure
The optimized pleated membrane design allows for a filtration area of ≥0.74㎡ per filter element, increasing the effective filtration space by more than 30% compared to traditional filter elements, significantly improving dirt holding capacity and service life. Combined with precise graded filtration accuracy, it achieves highly efficient interception of fine particles, with stable filtration efficiency. It supports integrity verification such as bubble point testing and diffusion flow testing. At 25℃, the maximum positive pressure differential reaches 4.3 bar and the reverse pressure differential 3.0 bar, maintaining stable filtration performance even under complex operating conditions, reducing replacement frequency and maintenance costs.
Meets diverse and stringent requirements
Covering a full range of lengths from 5 to 40 inches, it adapts to the installation needs of mainstream filtration equipment without additional modifications. Two membrane types are available: hydrophilic and surface-modified, suitable for different filter media such as water-based and oil-based media. Seals and connector materials can be customized as needed. Combined with the temperature and corrosion resistance of perfluorinated materials, it is widely applicable to diverse and stringent scenarios such as semiconductor electronic-grade chemical filtration, high-purity reagent purification in the pharmaceutical industry, and high-temperature corrosive gas treatment, achieving flexible application with "one core adaptable to multiple operating conditions".

FAQ
What corrosive media can this filter cartridge withstand? What is its operating temperature range?
Made entirely of PFA/PTFE material, it can withstand strong acids, strong alkalis, strong oxidizing solvents, and various organic solvents; the maximum operating temperature reaches 190℃, and it withstands pressure differentials more stably at room temperature (25℃).
How to choose filter cartridges with different precision? How to verify filtration integrity?
Precision covers 0.05-1.0μm, and can be matched to the required scenario: 0.05/0.1μm is suitable for electronic-grade high-purity filtration, 0.2/0.45μm is suitable for pharmaceutical/reagent purification, and 1.0μm is suitable for coarse filtration pretreatment; supports bubble point/diffusion flow testing to verify filtration reliability.
Does the cleanliness index of the filter cartridge meet the requirements of the semiconductor/pharmaceutical industry?
Fully meets the requirements. Metal leaching ≤25ppb/filter, far below the electronic grade industry standard; TOC residue ≤10ppb, meeting pharmaceutical-grade high-purity media requirements; 0.2μm particle residue ≤15 particles/10mL, avoiding the risk of microparticle contamination of the process.
What are the installation specifications for the filter cartridges? Is customization supported?
Lengths range from 5-40 inches, outer diameter 67mm, inner diameter 32mm, compatible with mainstream filtration equipment; customization options are supported: membrane type, sealing/connector material.
What is the approximate lifespan of the filter cartridge? How to extend its service life?
Due to varying operating conditions, a 10-inch filter cartridge can be used continuously for 1-3 months under typical high-purity filtration scenarios; the optimized pleated structure increases the filtration area to ≥0.74㎡, improving dirt holding capacity by more than 30% compared to traditional filter cartridges, extending replacement frequency; it is recommended to control the operating pressure difference to ≤2.4bar and avoid overheating and overpressure to further extend lifespan.
What precautions should be taken when flushing the filter cartridge?
It is recommended to use high-purity water or a corresponding clean solvent for rinsing, with a rinsing flow rate of 10L/min and a rinsing volume of ≥120L, to ensure that TOC residue is reduced to below 10ppb; avoid sudden cooling and heating during rinsing, and control the temperature difference within 50℃ to prevent material damage from affecting the sealing performance.
