Short answer: A hopcalite filter is a bed of copper and manganese oxide catalyst that converts carbon monoxide (CO) into carbon dioxide (CO2) at room temperature. In a breathing air purifier it sits a … read more

Short answer: A zero air loss drain collects condensate in a small chamber and uses a level sensor to decide when to empty it. When the liquid reaches a high level, a pilot solenoid opens a diaphragm … read more
