Abstract
A chemical cartridge for respirators for respirators, the cartridge containing a chemical, e.g., potassium hyperoxide, which when acted upon by carbon dioxide and moisture, produces oxygen from a stream of inhaled air. Two discharge nozzles are provided which project into the chemical and out of which the regenerated exhaled air flows. The incoming flow occurs over a large area and the outflow occurs over a small area with the peripheral surfaces of the discharge nozzles being spaced substantially equidistant from an inlet surface of the chemical, thereby ensuring optimum use of the chemical for oxygen production purposes because a user's exhaled air is caused to flow completely through the entire space occupied by the chemical.
