Gaskleen® Light Series Filter Assemblies

Gaskleen Light filter assemblies have been designed specifically to provide the high-purity gas filtration required in solar cell and liquid crystal display manufacturing. The assemblies are available in two styles: the TFA3 has a high-flow, compact design, for use where space is limited; the TFA6 is designed for applications where higher flow capacity is desired.
  • 316L stainless steel electropolished housing
  • All-fluoro-polymer filter cartridge
  • High temperature and pressure capabilities
  • 100% integrity tested
  • Cleanroom manufactured and packaged
  • 100% helium leak tested
  • Minimized packaging reduces waste while maintaining product purity
Products in this datasheet may be covered by one or more patents, including US 5,510,026.
