Adjustable E-Vacs Hold Different Size Sheets Consistently For Machining

This customer was using a 1 HP blower motor to pull a vacuum to hold a sheet of Styrofoam in place while it was being machined. The system was designed for one size, though, and did not hold sheets of other sizes very well. Often, these would come loose during machining, causing an unacceptable level of scrapped parts. A new vacuum clamping system was designed, incorporating an array of Adjustable E-Vac Vacuum Generators, pulling a vacuum on a grid which accommodated all the sizes they needed. Then, they would simply turn the needed generators on to securely hold any size sheet.
