CTI-Cryogenics 8080-255K001 Helium Filtration Cartridge 265 PSIG Helix

CTI-Cryogenics 8080-255K001 Helium Filtration Cartridge 265 PSIG Helix

The CTI-Cryogenics 8080-255K001 is a helium filtration cartridge designed for use with CTI-Cryogenics cryogenic compressors. It filters pressurized helium gas to maintain system purity, rated for 265 PSIG (1827 kPa) service with 99.999% pure helium gas. These cartridges are a scheduled-replacement consumable and must be swapped at the manufacturer's recommended service interval to preserve compressor performance and cryopump efficiency.

Applications

CTI-Cryogenics helium filtration cartridges are used in closed-cycle helium refrigeration systems — specifically within the compressor unit that drives cryopumps in high-vacuum environments. The compressor circulates high-pressure helium gas between itself and the cold head; the filtration cartridge removes contaminants (moisture, oil aerosols, particulates) from the helium stream to protect the cold head and maintain cooling efficiency. These cartridges are a standard consumable in semiconductor fabrication facilities, thin-film deposition systems (PVD/CVD), ion implanters, MRI magnet support systems, and other cryogenic vacuum equipment that relies on CTI-Cryogenics or Helix Technology compressors. Regular cartridge replacement at the prescribed interval is critical to preventing cold-head damage and maintaining base pressure in the vacuum chamber. The 8080-255K001 is the correct cartridge for SC, SCW, 1020R, and 1020RW series compressors, which were among the most widely deployed CTI units in semiconductor and research environments from the 1980s through the 2000s and remain in active service today.
