The pressure vessel of an abrasive blast machine, which holds the grit and feeds it into the compressed air line through a metering valve. The blaster controls it remotely with a deadman switch at the nozzle. Crews talk about filling, choking and dumping the pot, and moisture in the air supply that clumps the abrasive is a constant fight, hence aftercoolers and moisture separators.
