Unix5100 + filter 531 (A1B1E1K1) / Sorbent (Rusia)*
- Material: Silicon
- Filter cartridge 531 with the ability to filter inhaled air from organic, inorganic and acidic gases and vapors, ammonia and its organic derivatives. The filter is used when the volumetric oxygen content in the air is at least 17%, with the content of gases and vapor harmful substances at ambient temperatures from - 40 to + 40 ° C.
- The product meets and exceeds  European standards EN 14387
- Effective time of the filter cartridge :  Test results with sample toxic gas vapors (with specified concentration, flow, temperature, humidity) are much higher than the requirements of the standard EN 14387 - copper Meaning longer usage time. Specifically:
+ protective effect time with  Hydrogen Cyanide is 2 times higher
+ The protective effect time with Chlorine is 2.5 times higher
+ The duration of protective effect with Hydrogen sulfide is 2 times higher
- Respiratory resistance: respiratory resistance is 60% smaller than EN 14387 and EN 143 regulations (equal to 58.8/100Pa). This is an important indicator, especially when used in hard working conditions. Lighter breathing helps the wearer spend less effort and can maintain wearing the mask for a long time.
- Filter box weight: 130g lighter than EN regulations.
- Meets EN136 Class 2, EN 14387, CE standards

DOTpro 460 K3 / Sorbent - Russia
- Use with MAG full mask to create respiratory protection against toxic ammonia gas in the air.
(Can be used with European full face masks)
- The product meets the criteria according to European standards EN 14387:2004 + A1 2008, including:
+ The protective effect time when tested with ammonia concentration of 7 mg/liter is 60 minutes
+ The resistance when an air flow of 30 liters/minute passes through is 140Pa
+ Weight 400g (20% lighter than EN standard regulations)
