LFX-PTFE™ PTFE Filter Bags

FiltraCore Asia’s LFX-PTFE™ PTFE Liquid Filter Bags are engineered for extreme chemical and high-temperature applications where conventional filter materials fail. Constructed from 100% PTFE throughout, they deliver reliable filtration performance in demanding industrial liquid filtration processes involving aggressive chemistries.

Manufactured using needle-punched felt or woven PTFE mesh, LFX-PTFE™ filter bags maintain consistent particulate retention and structural stability when exposed to strong acids, alkalis, organic solvents, and oxidising environments across the full pH 0–14 spectrum, with continuous operating temperatures up to 260 °C, subject to application conditions and system design.

Full PTFE construction, including media and stitching, ensures uniform chemical compatibility across the entire filter assembly, eliminating material mismatch risks and supporting stable operation in corrosive and high-purity applications. The low surface energy of PTFE reduces fouling and particle adhesion, enabling longer service intervals and predictable performance.

LFX-PTFE™ filter bags are suitable for corrosive chemical processing, solvent-based and flammable liquid systems, and high-purity liquid handling, where chemically inert media, thermal stability, and long-term reliability are critical.

Technical Specifications
  • Material: 100% PTFE (Polytetrafluoroethylene); available in needle-punched felt or woven mesh constructions
  • Micron Ratings: Typically 1 μm to 50 μm nominal (common: 1, 5, 10, 25, 50 μm); wider ranges available upon request depending on media configuration
  • Operating Temperature: Continuous service up to 260 °C; short-term excursions above 260 °C subject to application conditions and mechanical support
  • Construction: Sewn using PTFE thread (standard), ensuring full chemical compatibility and high-temperature integrity
  • Collar / Ring Options: PTFE flange (mechanically secured or sewn); 304 or 316 stainless steel snap ring sewn into reinforced PTFE cuff; other configurations available upon request
  • Surface Characteristics: Low surface energy PTFE; non-stick, low-fouling, and non-fibre-shedding
  • Chemical Compatibility: Excellent resistance to strong acids, alkalis, organic solvents, and oxidising agents; suitable across the full pH 0–14 spectrum
  • Flammability: Inherently non-flammable and self-extinguishing under normal operating conditions; suitable for use in flammable liquid environments

Applications
  • Chemical Processing & Petrochemicals – Filtration of strong acids and alkalis, solvent purification, and aggressive batch processing (subject to chemical compatibility and operating conditions)
  • Aroma Chemicals, Flavour & Fragrance – Solvent-based liquid handling, repacking operations, and final-stage polishing of purity-critical products (verify solvent compatibility and filtration objective)
  • Pharmaceutical & Biotechnology – High-purity process liquids, ingredient solutions, and CIP chemical streams (not intended for sterile final filtration)
  • Food & Beverage – Hot, acidic, or caustic liquids where food-contact compliant variants are required
  • Electronics & Semiconductor – Ultrapure chemical baths, etchants, and high-temperature rinse fluids (application-specific compatibility validation required)
  • Mining & Mineral Processing – Corrosive leachate, solvent extraction streams, and chemically aggressive slurry systems
  • Power Generation & Utilities – High-temperature condensate systems and chemical cleaning solutions
  • Water Treatment & Desalination – Aggressive brines, caustic cleaning solutions, and oxidising chemical dosing streams (verify concentration, temperature, and material compatibility)
  • Other Extreme-Duty Industrial Processes – Applications requiring maximum chemical resistance and continuous service temperatures up to 260 °C, subject to application validation
