NOTE: you cannot use a vacuum table with a standard vacuum cleaner for any significant duration of time. It is a fire hazard. The pump system shown here includes a vacuum pump designed to work under pressure (which is what is needed to good vacuum clamping) for prolonged periods of use. The package also comes with all the necessary under pressure and safety connections.
While the pumps are designed to work with “under pressure” you cannot close off a pump completely for flow as it will over heat. The package comes with a pre installed and tuned under pressure valve. NOTE the pressure gauge addition is an additional item and is not included
