The capsule filter adopts a fully welded structure to avoid any risk of leakage, and the design without metal parts ensures that the fluid is pure and uncontaminated. PFA itself is insoluble in almost all chemicals and is suitable for complex media such as strong acids, strong bases, and organic solvents, especially for high-purification processes that require ultra-low metal contamination and particle release.
Core advantages of products
- High-purity PFA material: All PFA material structure ensures extremely low dissolution.
- High temperature tolerance: The operating temperature can reach 200~260°C, suitable for thermochemical processes.
- Strong chemical compatibility: Compatible with highly corrosive liquids such as HF, HNO₃, H₂SO₄.
- Pollution-free structure: No adhesive, no metal, reducing the precipitation of particles and metal ions.
- Simple packaging: Integrated capsule structure, easy to install, replace and maintain.

FAQ
What liquids are suitable for PFA filter capsules?
PFA capsules can be used for filtering highly corrosive liquids such as hydrofluoric acid, nitric acid, sulfuric acid, and hydrogen peroxide, and are particularly suitable for high-purity chemicals and electronic-grade solvent processing.
How is PFA Filter Capsule different from traditional filter element structures?
PFA capsules are fully enclosed structures with built-in filter membranes and are encapsulated by heat welding to avoid contamination and leakage problems and improve filtration safety and purity.
How to determine whether PFA filter capsules need to be replaced?
When the filtration pressure difference increases, the flow rate decreases significantly, or there are signs of liquid deterioration, the filter capsules should be replaced in time. It is recommended to set a periodic inspection mechanism based on the frequency of use.
Are there any installation direction requirements?
Yes, most PFA capsule filters have a "liquid from top to bottom" flow direction, and must be installed correctly according to the flow direction arrow on the product to ensure filtration efficiency.
Can PFA capsules be used for gas filtration?
This product is mainly designed for liquid filtration, but if the use conditions are suitable, it can also be used for coarse filtration of certain corrosive gas media. Please consult the technical parameters for details.
