Designed to extract dust directly from the power tool, the new HEPA Wet/Dry Vacuum from Alpha uses a HEPA 13 cartridge with two independent filter chambers and features automatic filter cleaning to help maintain consistent suction. Other features include an onboard receptacle for power tools, visual and audio warning signals, and a dust-tight lockable connection nozzle. The vacuum has a cannister volume of 9.3 gallons (model HEPA1035) or 13.2 gallons (model HEPA1050); an optional adapter plate is available for common tool cases.
