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-fluoropolymer 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
