Overview
GVS Capsule Filters utilize high-performance membrane media featuring broad chemical compatibility and high flow characteristics as the primary filtration layer. No adhesives, binders, or surfactants are used during the manufacturing process to ensure superior downstream cleanliness. All filters are rinsed with high-purity water to minimize extractables and extend the service life of downstream final filters.
These filters are widely used across pharmaceutical, biotechnology, food & beverage, electronics, chemical processing, laboratory applications, and various purified water systems.

Comparison
．Both the CSK Series and CIK Series belong to the Capsflow Capsule Filter product family. They are available with PES, PTFE, and PP filtration media for liquid and gas filtration in applications such as biopharmaceutical manufacturing, food & beverage, chemical processing, and laboratory operations.
While both series share the same filtration technology, they are designed to meet different application requirements, as summarized as below:
| Item |
CSK series | CIK series |
| Product Positioning | General-purpose capsule filter | Process-grade, high-flow capsule filter |
| Filtration Area | 500、1000、1500、2100 cm² | 1480、2650、5500、11000、16500、22000 cm²（2.5"~40"） |
| Size | Compact and space-saving design | Larger size, designed as a replacement for conventional cartridge filters |
| Flow Rate | Low to medium flow rates | High flow rates for large-volume processing |
| Connection Options | NPT, Swagelok, Hose Barb, Tri-Clamp | Primarily designed for process piping systems with integrated vent and drain ports |
| Integrity Testing | Available on selected models | Supports in-line integrity testing |
| Typical Applications | Laboratory, pilot-scale, and small-batch production | GMP manufacturing, biopharmaceutical processing, food & beverage production, and large-scale industrial processing |
Select CSK Series:
For laboratory, R&D, pilot-scale, or small-batch production applications where a compact design and cost-effective capsule filter are required.
Select CIK Series:
For GMP production lines and high-flow process applications where a larger filtration area, longer service life, and process-grade performance
