The ARC 50 is a professional CBRN (chemical, biological, radiological and nuclear) air filtration and emergency ventilation system designed for installation in protected environments such as safe rooms, civil defence shelters, bunkers and critical infrastructure.

The system provides fresh filtered air while creating positive overpressure inside the protected space, establishing a Toxic Free Area (TFA) and ensuring safe breathing conditions during contamination scenarios.

Designed for reliability and redundancy, the ARC series combines electrical operation with manual backup to ensure functionality even during power outages.
