Ultramet-L® 4281, 4581 Series Assembly

The Ultramet-L® 4281/4581 Series Filter Assemblies are available with an all 316L stainless steel housing and either a 316L stainless steel or nickel filter. They are designed for ≥ 3 nanometer (0.003 μm) filtration of semiconductor grade gases. The 4281/4581 series filters are recommended for all applications with process gases that are compatible with 316L stainless steel or nickel. For applications with corrosive gases, such as halogen containing acid gases, the nickel filter assembly is recommended only if the gas is known to be anhydrous.
  • State-of-the-art 316L stainless steel or nickel media
  • Excellent particle removal efficiency vs. pressure drop
  • Accommodates extremely high flow rates for the assembly size
  • Excellent gas displacement and desorption characteristics
  • High temperature and pressure capabilities
  • Compact size for ease of installation
  • Wide variety of fitting options available
  • 100% helium leak tested
  • Cleanroom manufactured and packaged
  • Housing material meets or exceeds VIM VAR specifications.
