Purpose
PROX (IP-4MK) is designed to protect the respiratory system, eyes and skin from hazardous impurities despite their concentration in the air and to work in lack of oxygen conditions. The gas mask is completed with the facepiece and is equipped with communication system.
Isolating gas mask principle of operation is based on using chemically bonded oxygen. It has closed-circuit breathing system. Exhaled air is delivered into the regenerative cartridge. There is a special substance inside the regenerative cartridge which absorbs carbon dioxide and humidity containing in the exhaled air and releases necessary oxygen for breathing.
