Respirators - CO

At different factories there is a frequent need to protect operating personnel from emissions of sulfur dioxide, hydrogen chloride, hydrogen fluoride, ammonia, hydrogen sulfide, etc.

IMT-Filter Company has developed and produced materials intended for removal certain groups of substances (acid or basic gases) as well as special sorbents for selective removal of specific pollutants (hydrogen sulfide, formaldehyde).

The filtering materials PANION® are indispensable and very effective in production of:

  • light and lighted respirators (shaped, particulate respirators etc.) of different construction (valveless, with exhalation valve etc.);
  • portable evacuation means from areas of man-made and natural disasters (self-rescuers), emergency situations;
  • heavy respirators and gas masks.

The materials PANION® can be used in respirators both separately and combined with modern dust materials. In such combination the respirator provides a complex respiratory protection from dust, aerosols as well as toxic chemical contaminants in the form of gases and vapors.

The following ion exchange fibers PANION® are tested and can be used as barrier material for production of respirators:

The materials used in the manufacture of respirators don’t adversely affect the human body, which is confirmed by corresponding certificates.

According to customer requirements filtering materials can be developed with new or changed properties.

The first mention of respirators can be found in the XVI century, in the works of Leonardo da Vinci, who suggested that a finely woven cloth dipped in water could protect sailors from a toxic weapon made of powder that he had designed. Alexander von Humboldt introduced a primitive respirator in 1799 when he was working in Prussia as a mining engineer.
