Core advantages of products
- All-PFA structure: no metal, no additives, ensuring that the liquid is not contaminated during the entire filtration process.
- Disposable sealing design: effectively prevent leakage and secondary contamination, quick installation, and reduce the risk of cross-contamination.
- Excellent chemical compatibility: suitable for various strong acids and solvents such as HF, H₂SO₄, HNO₃, HCl, Acetone, etc.
- A variety of filtration precisions and sizes are available: the filter element precision ranges from 0.05μm to 10μm to meet different purity requirements.
- Adapt to a variety of interfaces: support Flare, NPT, Swagelok, PFA welding and other connection methods, flexible installation.
Application
Semiconductor wet process chemical liquid filtration
Final filtration of high-purity chemicals, reagents and solvents
Precision liquid handling in LCD/LED manufacturing processes
Safe filtration of solvents in pharmaceutical and bioprocessing
Filtration protection of highly corrosive fluid systems in laboratories
Installation and use recommendations
- Installation direction confirmation: Please strictly follow the marked "IN/OUT" flow direction for installation. Wrong flow direction will cause filtration failure or damage to the filter element.
- Avoid dry burning or no-load use: Before starting, make sure there is liquid in the system to avoid deformation or performance degradation of PFA material due to no-load burning at high temperature.
- Control temperature and pressure range: It is recommended that the operating temperature does not exceed 200°C and the working pressure does not exceed 0.5 MPa to avoid leakage or bursting caused by over-limit.
- Avoid external mechanical shock: PFA material has certain flexibility but is sensitive to sharp objects. Avoid falling, heavy pressure or impact during installation and transportation.
- Note on cleaning and replacement: PFA capsule filters are generally disposable. If they must be cleaned and reused, please confirm that they are washable and use appropriate cleaning methods.
- Interface sealing inspection: Before installation, please check whether the interface sealing ring, threaded parts, etc. are clean and intact. After installation, air pressure or hydraulic pressure test can be performed to confirm that there is no leakage.
- Storage environment requirements: Store in a cool and dry environment, avoid direct sunlight and extreme temperature differences. It is recommended to seal it in an anti-static bag.
FAQ
Is it suitable for high cleanroom environment?
Yes. PFA capsule filters are suitable for Class 100 or higher cleanrooms and are widely used in semiconductor and microelectronics production environments.
How long is the shelf life?
If stored in an unopened, dry environment, the shelf life can be up to 3 years. It is recommended to check whether the packaging is intact and has no signs of damage or aging before use.
Is the filter material certification or test report provided?
Yes. Material certification, particle release test, metal ion precipitation test, cleanliness test report, etc. can be provided on demand.
Is it suitable for high viscosity or particle-containing liquids?
For high viscosity liquids, large flux or low resistance models can be selected; if the liquid contains large particles, a pre-filter should be added at its front end to prevent clogging.
