The ENMX Capsule Filter features a Nylon 6,6 membrane engineered for ultrafine particle removal in critical high-purity applications. With broad chemical compatibility and consistent performance across scales, ENMX filters are ideal for ultrapure water systems, electronic-grade chemicals, solvents, and photoresists.

These hydrophilic filters are pulse power flushed until rinse-up reaches >18 Megohm-cm and <3 ppb TOC. Each unit is 100% integrity tested and constructed to provide high retention, high throughput, and long service life in demanding environments.

Key Features:

• Nylon 6,6 Membrane: Excellent compatibility with chemicals, solvents, and aqueous fluids

• High Purity Performance: Pulse power flushed for minimal TOC and conductivity contamination

• Integrity Tested: Each filter individually validated for particle retention and filter integrity

• Low Extractables: Ideal for final filtration in high-purity systems
