4-chamber, 304 stainless steel air purification system engineered for facilities handling both radioiodine isotopes (I-129, I-131) and chemical process gases -- university and hospital radioisotope labs, nuclear medicine synthesis areas, and chemical facilities with mixed contaminant profiles. Laboratory and field deployment.
Configuration: 4-chamber sequential treatment -- pre-filtration, HEPA aerosol capture, dual-isotope iodine adsorption, and iodine-catalyzed VOC/process gas oxidation.

*VOC removal rate reflects Chamber 4 performance under representative test conditions per our chemical filtration technology. Confirm application-specific performance data with our engineering team.
Each contaminant class is treated by the chamber best suited to it -- coarse particulate, then HEPA-grade aerosols, then radioiodine-specific adsorption, then chemical gas oxidation -- rather than relying on one filter media to do everything.
The iodine adsorption chamber is engineered for both I-129 and I-131 in elemental and organic (methyl iodide) forms -- relevant for facilities running mixed radioisotope work, including nuclear medicine synthesis and research lab operations.
Standard corrosion-resistant construction suited to the mixed chemical and radiological environments common in labs and chemical processing facilities.
Chamber 4's iodine-catalyzed oxidation handles VOCs and common process gases (H₂S, mercaptans, ammonia) in the same pass -- no separate carbon-only stage required.
Sized and constructed for both fixed laboratory installation and portable field use, matching how university, hospital, and chemical facility teams actually deploy contamination control equipment.
