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

1100 Silicone + 521 / Sorbent - Russia
- Uses: filtering organic toxic gas vapors (organic solvents, acetone, benzene...); inorganic (such as Cl2, H2S, HCN, HCl,...); SO2 and acid.
- Respiratory resistance: only 39.2 Pa, 2.5 times lower than the requirement of EN standard (100/39.2 Pa). 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.
- Effective time of the filter cartridge: Test results with sample toxic gas vapors (with specified concentration, flow, temperature, humidity) are much longer than the requirements of EN 14387 standard - copper Meaning longer usage time:
+ Protection time with Hydrogen Cyanide reaches 50 minutes, 2.5 times longer (50/25 minutes)
+ The protective effect time with Sulfur dioxide reaches 70 minutes, 3.5 times longer (70/20 minutes),
+ The protective effect time with Chlorine reaches 50 minutes, 2.5 times longer (50/20 minutes)
+ The protective effect time with Hydrogen sulfide reaches 80 minutes, 2 times longer (80/40 minutes).

- The manufacturing material is Silicone so it is very soft and comfortable to wear
- Appropriate structure, fits the wearer's face. Does not affect eye vision. Does not affect the need to wear additional protective equipment such as hats, goggles, or face shields.
- The carrying strap has a high elastic feature, the length can be adjusted to fit. Easy and quick to put on and take off. Easy to clean when wiped or cleaned with water or detergent.
- Working temperature from −40 ° C to + 40 ° С.
- Meets EN 140:1998 + AC:1999 standards.
