MSA All-Vision Diaphragm Chemical Cartridge Respirator
The MSA All-Vision Gas Mask was made for a variety of applications, including law enforcement and industrial use. This All-Vision Chemical Cartridge Respirator featured a central speech diaphragm, two cheek exhale valves and a filter canister attached directly to the chin to protect against tear gas. This example was made by Mine Safety Appliances in 1971.
