The exceptional modularity of Beth-El Industries allows it to be operated as a ventilation system and with a quick change of filter it becomes a life saving CBRN filtration system that can operate around-the-clock to provide collective protection to the crew. The system uses minimally aging carbon, which is especially important in high humidity environments to remove TICs and TIMs (Toxic Industrial Chemicals & Materials) from the air. The systems are easy to operate, light weight, and they have minimal power requirements.
