0.5 μm Fiberglass Sintered Filter Element 70x30

This 0.5 μm fiberglass sintered filter cartridge delivers exceptional filtration purity in demanding fluid handling processes. This high-performance sintered filter combines advanced materials science and precision sintering technology. Unlike traditional glass fiber filter media, it utilizes a controlled sintering process to bond tiny glass fibers into a robust, porous monolithic structure. The resulting 0.5-micron depth filter combines excellent particle retention with the durability and ease of cleaning typically found only in all-metal filters.

Designed for critical applications requiring the removal of submicron particles, colloids, and fine mist, this cartridge offers reliable and consistent performance. Its robust construction prevents fiber migration or media bypass, ensuring all fluids pass through its sophisticated depth filtration structure, making it ideal for final fine filtration, sterile exhaust, or protecting high-value downstream components.

• Pharmaceutical & Biotech: Final polishing of injectables (WFI), buffer solutions, cell culture media, and sterile gas venting.

• Microelectronics: Ultrapure water (UPW) polishing, chemical filtration, and photoresist processing.

• Chemical Processing: Removal of catalyst fines and sub-micron particulate from high-value process streams.

• Laboratory & Analytical: Critical sample preparation and solvent clarification

Huahang Filter leverages controlled thermal bonding processes to transform high-purity fiberglass media into a robust, shape-retaining filter element. The 0.5μm sintered filter showcases our ability to deliver the efficiency of depth filtration with the structural benefits of a sintered component, solving challenges where both ultra-fine retention and physical integrity are non-negotiable.

Key Manufacturing Advantages

• 1. Rigid, Migration-Resistant Structure: The sintering process locks fibers in place, eliminating the risk of media shedding, while providing excellent structural stability.
• 2. True Absolute Depth Filtration: The three-dimensional porous network guarantees the retention of 100% of particles at the rated 0.5-micron size and larger, offering predictable and verifiable performance for process validation.
• 3. Enhanced Durability & Cleanability: The bonded matrix can withstand higher differential pressures than loose media and can be carefully cleaned for reuse in certain applications, offering potential lifecycle cost savings.
• 4. High-Purity Material Composition: Manufactured from high-grade, binder-free fiberglass, ensuring excellent chemical compatibility and low extractables for sensitive processes.

Q1: How does a sintered fiberglass element differ from a standard pleated fiberglass cartridge?
A1: A standard cartridge contains loose or felted fibers that can shed or channel under pressure. A sintered element is a bonded, monolithic block of fibers, providing absolute-rated filtration, no media migration, rigid structural integrity, and potential for clean-in-place  reuse.

Q2: What is the recommended cleaning method?
A2: For reuse, gentle low-pressure backflushing with clean, compatible fluid or deionized water is recommended. Chemical soaking may be applicable depending on the contaminant. Always validate the cleaning cycle for your specific process. Note: Not all applications permit reuse.

Q3: What are the temperature and pressure limits?
A3: It can typically withstand continuous temperatures up to 300-400°C and operational pressures up to 5-10 bar (70-150 psi), depending on the specific grade and housing support. Consult the technical datasheet for exact specifications.

Q4: Is this element suitable for sterile liquid filtration?
A4: With its 0.5μm absolute rating, rigid structure, and sterilizability, it is an excellent choice for sterilizing-grade filtration of gases (vent filters) and can be used for sterile liquid filtration in pre-filter or specific final polish roles. Always conduct appropriate validation for the intended use.
