Filtration Capabilities: PP, PES, PTFE, PVDF, & Nylon Filters

  • Membrane Cartridges: Pleated microporous filters in Polypropylene (PP), Polyethersulfone (PES), PTFE, PVDF, and Nylon66, produced in ISO 9001 certified cleanrooms.
  • 1000+ Variants: Includes chemical filter solutions, CMP slurry filter options, photoresist filter types, metal-ion removal, gas filter/gas purifier units, and ultra pure water filter designs. Engineered for optimal flow, retention, and chemical compatibility (e.g., acid filter needs). We also supply compatible filter housings.
  • Rapid Lead Times: Standard or custom cartridge filter orders delivered in 2–3 weeks.
  • Cost Savings: In-house manufacturing provides significant savings on high purity filters.
