Separate supply filtration from tool filtration
Production, bulk delivery, recirculation, final filtration and equipment point-of-use positions can see different flow, temperature, pressure and cleanliness requirements even when the chemical name is the same. Confirm the installation position before selecting membrane area or pore option.
Critical selection factors
- Chemical identity, concentration, SDS and operating temperature.
- Expected particle load and retention validation method.
- Required flow, clean pressure drop and change-out limit.
- Housing or integrated assembly, connection and seal material.
- Extractables, metal-ion and rinse-down acceptance criteria.
Relevant Zhongfu filter families
All-fluoropolymer cartridges
PTFE membrane and PFA support structures for compatible critical chemistries, available in high-retention, high-flow and ultra-high-flow configurations.

Integrated PFA wet-process filter
PTFE membrane in an all-PFA housing and flow path for selected single-wafer and batch wet-tool positions. Published screening data include options from 0.2 µm to 10 nm, up to 185°C and 0.59 MPa at 50°C; final application approval remains required.

Data to include in an RFQ
Provide chemical and SDS, process position, concentration, temperature, flow, inlet pressure, allowable pressure drop, connection, current filter or housing, quantity, destination and required date.
SC-1, SC-2, SPM and phosphoric-acid references identify potential process areas. They do not establish universal compatibility for every concentration, temperature or tool configuration.
