Section 3 — Design

Design Advantages

4-Chamber Sequential Treatment

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.

Dual-Isotope Targeting

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.

304 Stainless Steel Housing

Standard corrosion-resistant construction suited to the mixed chemical and radiological environments common in labs and chemical processing facilities.

Simultaneous VOC and Process Gas Treatment

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.

Laboratory and Field Deployment

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.
