The Czech CM-4 was originally developed in 1971 for Czechoslovakian civilian use. This ventilator gas mask provides protection to the face, eyes, and respiratory system from toxic gases, vapors, and aerosols including radioactive dust and biological contaminants. The neck strap and five-point harness make it extremely easy to adjust for a comfortable and secure fit. The package includes a sealed 40mm NATO filter.
Why choose this gas mask?
There are two types of respirators: Air-purifying respirators, also known as “gas masks”, which decontaminate the air by forcing it through a filter, and air-supplied respirators, which deliver fresh oxygen from a fully-sealed tank.
