GF-90 CBRN Gas Filter
GF-90 / CBRN GAS FILTER GF-90 CBRN Gas Filter
GF-90 CBRN Gas Filter is a compact filtration solution developed for collective-protection systems in enclosed military environments. Its composite architecture combines HEPA particulate filtration with activated-carbon gas adsorption to address airborne particulates and toxic chemical agents in vapor or gaseous form while maintaining controlled airflow.
Composite HEPA and activated-carbon filtration for collective CBRN protection in vehicles, shelters and fixed installations.
Composite Filtration for Collective CBRN Protection
The GF-90 CBRN Gas Filter is intended for collective-protection systems requiring filtration of incoming air in contaminated or high-risk environments. The supplied product information describes protection against toxic chemical agents in vapor or gaseous form and airborne particulate threats when used with its HEPA filtration stage.
The filtration architecture combines a HEPA particulate filter with an activated carbon gas filter, providing separate stages for particulate removal and gas adsorption.
Compact CBRN Filtration for Vehicles, Shelters and Fixed Installations
GF-90 is described for military vehicles and shelters requiring collective CBRN protection. Typical applications include armored vehicles, tactical shelters, command posts, mobile units and other enclosed operational spaces where controlled air filtration is required.
The compact configuration is also suitable for fixed installations requiring CBRN filtration capability.
