ABSTRACT:
A portable vacuum system adapted to be worn on the back of an operator for collecting dust and debris generated during use of an air powered tool such as a grinder or a sander. The portable vacuum system is powered by the same pressurized air source used to power the tool, thus eliminating the need to tether the operator to additional hoses. The portable vacuum system comprises a collection bag assembly that has mounted thereto a venturi device which generates a vacuum pressure from a pressurized air supply. A vacuum hose is connected between the vacuum inlet to the venturi device and the power tool. A fluid manifold directs pressurized air through first and second on/off valves to the venturi device and the power tool to provide the operator with the ability to separately control the supply of pressurized air to each device.
