Isolation mask IP-4M is designed to protect the respiratory system, eyes and facial skin from any harmful impurity in the air, regardless of its concentration, as well as for work in conditions of lack of oxygen in the air in the temperature range from -40 ?? to + 40??.

The gas mask IP-4M has a pendulum breathing system. At exhalation the gas mixture on the connecting tube of the front part falls into the regen
An effective cartridge in which carbon dioxide and moisture are absorbed and oxygen is released in a volume proportional to the amount of absorbed substances.

From the regenerative cartridge the gas mixture enters the breathing bag. When inhaled, she enters the regenerative cartridge from the secondary respiratory bag, where it is further cleared of carbon dioxide and returns to the respiratory system via the connecting tube.

The gas mask IP-4M is issued for work in assembled form with a regenerative cartridge attached to the respiratory bag and the corrugated tube with the front part. The branch pipe connecting the front part and the corrugated tube must be tightly closed with a stopper.
