ABSTRACT:
A metal respirator cartridge which may be completely assembled prior to performing the encapsulation process wherein the periphery of the filter element is completely sealed to the metal cartridge body. The cartridge has a metal cover provided with a unique air inlet opening which performs two distinct functions, that is, as an opening to admit air into the metal respirator cartridge as is normal; and as an opening which, during the manufacturing process, allows a liquid sealant to be introduced into the interior of the metal cartridge body to encapsulate the periphery of the filter element.
