Automatic military grade NBC filtration units uses data from NBC detection systems and changes “close up” and “filtration” modes without automatic operation
An optional ‘Stand by line” to a primary NBC filtration system can be automatically engaged
Sophisticated control systems continuously can be integrated into an existing building management system which balance the airflow within the NBC filtration bank, thus maximizing the efficiency of the NBC filters
