Compare the construction, not only the price.
All-fluoropolymer and semi-fluoropolymer routes are compared against the same chemistry, retention, flow, cleanliness, quantity and trade terms.
Liquid · gas filtration · gas purification
Filtration structured by the process path.
Start with liquid or gas. Liquid filtration separates DIW from process chemistry; gas supply separates particle filtration from molecular purification. Zhongfu engineered liquid filters remain clearly identified from complementary sourced routes.
One qualification framework, three production environmentsBulk chemical filtration, wafer-process point-of-use control and packaging/test utilities are matched as one connected solution.

A practical China supply model
Cost, performance and schedule—each tied to evidence.
We make commercial and technical discussions comparable at quotation and qualification stage.
Select from documented family options.
High-retention, high-flow and ultra-high-flow formats are screened against pressure drop, temperature and the planned acceptance test.
Coordinate production from China.
Configuration, quantity, required date, destination and Incoterm are reviewed before a production and delivery commitment is issued.
No fixed saving, performance superiority or standard delivery time is implied; each is confirmed for the selected configuration.

Product architecture
Two media paths. No category overlap.
Liquid products divide into DIW and chemical routes. Gas products divide into particle filtration, purification and separate gas-path components.
DIW & chemical filtration
Cartridge, POU, capsule and housing formats organised by the liquid and process position.
Explore liquid filtration →Gas filtration & purification
Particle filters, gas-specific purifiers, diffusers and flow-control components remain functionally separated.
Explore gas products →Applications
Built around the process position, not a catalogue shortcut.
We separate production filtration, recirculation, final filtration and point-of-use duties because the same chemical can demand different retention, flow and cleanliness profiles at each position.
Wet etch and clean
All-fluoropolymer cartridges and integrated filters for high-purity acids, bases and cleaning chemistries.
