Short answer: Mines use compressed air for drills, rock breakers, shotcrete, plant instruments and refuge chamber breathing air, while flotation usually runs on separate low-pressure blowers. Australi … read more

Short answer: A rotary screw compressor traps air between two meshing helical rotors and their housing. As the rotors turn, each trapped pocket moves along the rotors and gets smaller, so the air pres … read more

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: Pressure dew point (PDP) is the temperature at which water vapour starts to condense out of compressed air at line pressure. If the air in your pipes cools below its pressure dew point, … 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
