EXAIR's new Premium Heavy Duty Dry Vac™ System is a rugged, industrial duty vacuum cleaner that has been engineered to vacuum high volumes of dry materials in less time than ordinary vacs. It now comes complete with a 30, 55 or 110 gallon drum, making it easy to meet your specific requirements. The wear resistant design is suitable for the clean-up of abrasive materials like steel shot, garnet, metal chips, and sand, yet can also be used for general purpose applications. 
The Premium Heavy Duty Dry Vac System is compressed air powered and attaches to the included drum. It is extremely quiet at 82 dBA (half the noise of electric vacs), making it suitable for a wide variety of applications. Surrounding air is kept clean by the 0.1 micron filter bag that traps particles when vacuuming dusty materials. There are no motors or impellers to clog or wear out. It is covered by a five year warranty.
The Premium Heavy Duty Dry Vac System comes complete with a 10' (3m) static resistant hose, 20' (6m) compressed air hose, shutoff valve, pressure gauge, heavy duty tools, toolholder (most systems), drum dolly and 30, 55 or 110 gallon drum.
