The vacuum is generated by the use of an electric vacuum pump and external compressor. The vacuum boxes are rated to either 20 inch Hg (10psi/0,7bar) or 10 inch Hg (5psi/0.37bar) depending on usage.

The vacuum boxes have calibrated pressure relief valves fitted as standard. Also the boxes cannot be damaged by drawing too great a vacuum.
