PES Filter Cartridge

PES (Polyethersulfone) Filter Cartridge is a hydrophilic membrane filter known for high flow rate, low protein binding, and excellent filtration efficiency. It provides absolute-rated filtration with strong bacterial retention capability. They are ideal for critical processes requiring 0.2 μm or 0.45 μm sterile-grade filtration. With strong chemical resistance and high throughput, PES filters ensure reliable and reproducible performance in demanding sterile applications.

Main Applications: Biopharmaceutical filtration, sterile filtration, laboratory filtration, vaccine production, and high-purity water systems.

PVDF Filter Cartridge

PVDF Filter Cartridge is constructed with Polyvinylidene Fluoride membrane, offering excellent chemical resistance and strong oxidation tolerance. It can withstand aggressive chemicals, solvents, and high-temperature conditions while maintaining stable filtration accuracy.

Main Applications: PVDF cartridges are widely used in chemical processing, electronics industry, high-purity water systems, and oxidizing liquid filtration. They are suitable for filtering acids, alkalis, solvents, and aggressive fluids. With durable structure and long service life, PVDF filters are preferred in harsh industrial environments requiring both precision and chemical durability.

PTFE Filter Cartridge

PTFE Filter Cartridge is designed with a highly hydrophobic membrane, delivering superior chemical resistance and high temperature tolerance. It provides excellent performance in aggressive solvents and critical gas filtration applications.

Main Applications: Sterile air filtration, pharmaceutical vent filtration, compressed air systems, strong acid/alkali filtration, and high-purity chemical processes.

Nylon Filter Cartridge

Nylon Filter Cartridge offers excellent mechanical strength and good compatibility with organic solvents. It is hydrophilic and provides stable filtration performance in various liquid filtration systems.

Main Applications: Beverage filtration, wine filtration, solvent filtration, pharmaceutical intermediates, and fine chemical processing.

Glass Fiber Filter Cartridge

Glass Fiber Filter Cartridge features deep-layer filtration structure with high dirt holding capacity and strong adsorption ability. It is ideal for high-flow and high-particle-load filtration environments.

Main Applications: Oil filtration, high-temperature liquid filtration, paint and coating filtration, industrial water treatment, and heavy particle removal systems.
