This is an as built model of my 8 zone vacuum system I build for my ShopBot PRS 4x8. It's got 4 lighthouse motors with check valves that can be turned on and off individually. The motors are mounted in a box with a baffled exhaust that drastically cuts down on noise. There are 8 zones in the table that are 24"x 24" each. The valves allow you to direct suction to anywhere on the table you want. This allows for suction of small parts and large sheets with the flip of a few valves and switches.
