  • Patent number: 11040226
    Abstract: Disclosed is a modular serviceable cartridge assembly for a respirator exhalation unit that is simple in construction and that allows quick-connect of an exhalation valve cartridge in a mask to minimize the need for reconfiguration when changing personal protective equipment, and that allows for easy removal and breakdown for servicing and/or replacement of individual components of the exhalation valve without modifying or replacing other elements of the protective mask. The assembly may be convertible from a negative pressure valve assembly to a positive pressure valve assembly, and vice versa, and a grill may be provided on an outlet side of the cartridge assembly, the rotation of which converts the assembly from a negative pressure valve to a positive pressure valve.
