Application
Pharmaceutical Filtration
GMP-compatible, contamination-free filter fabrics engineered for the pharmaceutical and API industry. Ultrasonic welding, seamless construction, and full traceability — designed for validation and regulatory compliance.
The Challenge
Pharmaceutical filtration demands absolute purity. Active Pharmaceutical Ingredients (APIs), intermediates, and excipients must be separated without introducing particulate contamination, fibre shedding, or chemical extractables. Every filter cloth in a GMP environment is a potential contamination source — and a validated one must not compromise product integrity.
Traditional sewn filter cloths release thread fragments and needle-hole particles into the product. In pharmaceutical production, this is unacceptable. The industry requires filter media that eliminate stitching contamination entirely while maintaining the mechanical strength needed for pressure filtration and centrifugal forces.
Typical Pharma Filtration Tasks
Why Pharmaceutical Filtration is Different
In pharma, a filter cloth is not just a consumable — it is a validated process component subject to GMP scrutiny.
Zero Contamination
Conventional stitching introduces thread particles and needle fragments. Ultrasonic welding eliminates this contamination vector entirely — no thread, no needles, no fibres.
Seamless Construction
Seamless filter cloths remove all seam-related weak points. No overlap ridges, no stitching holes — a continuous filtration surface that meets the highest purity standards.
GMP & FDA Compliance
Materials compliant with FDA 21 CFR, EU Regulation (EC) 1935/2004, and USP Class VI. Full traceability from raw material to finished cloth with batch documentation.
Chemical Compatibility
Resistant to aggressive solvents (DCM, THF, toluene, methanol), acids, and bases used in API synthesis. Material selection matched to your specific process chemistry.
Validation Support
We supply IQ/OQ documentation, material certificates, extractable test reports, and change notification protocols to support your pharma qualification process.
Defined Retention
Precise particle retention ratings from 1 µm to 100 µm. Consistent pore size distribution ensures batch-to-batch reproducibility — critical for validated processes.
