Eastern Europe type NBC / CO2 filters 

As an example, many shelters in Eastern Europe are still integrated with old type of filtration units that require specific type of NBC filters / CO2 Filters (ФПУ-200, ФП-300, РП-100, and other). We offer a modern upgraded version of these filters that allow simple replacement of old filters without the need to replace the complete filtration system (in case it is operational).
