Abstract: A device for emptying pressurized liquid-containing aerosol cans. A closed storage drum has an aerosol can-containing chamber held adjacently to it. An aerosol can may be placed in the chamber, the chamber closed and a piercing pin passed through a low point of the aerosol can. The contents pass outwardly from the can and from the chamber into the storage drum. Preferably, a vapor filter is positioned on the drum so that any vapors passing out of the drum are absorbed by the filter. The system can remove 98% of the aerosol can contents. The process of using the device is also described.
