Beth-El’s NBC filtration systems for tents are compact, heavy-duty, high performance ventilation and CBRN filtration systems that supply clean air to tent compartments in times of peace or during conventional combat (CBRN filter bypassed) and filtered air for times of CBRN contamination. By introducing filtered air and creating overpressure inside the compartment, the interior of the tent is effectively protected, enabling convenient freedom of movement inside the protected area without the need for gas masks or protective clothing.
