Energy Required for Vacuum Generation

The energy required for vacuum generation increases disproportionately to the attained vacuum. Increasing the vacuum from -600 mbar to -900 mbar, for example, increases the holding force by a factor of 1.5, but the evacuation time and the energy needed to achieve this vacuum value increases by a factor of 3. This means that only the vacuum required should be generated in the working area to keep the energy expenditure and the operating costs at a minimum.

Common working areas

  • for air-tight surface (e.g. metal, plastics, etc.): -600 to -800 mbar vacuum
  • for porous materials (e.g. cardboard boxes, particle boards, MDF sheets, etc.): -200 to -400 mbar vacuum; in this range the necessary holding force is generated by increasing the suction rate and the suction area.

On this website, the holding forces of the suction cups are always specified at an efficient vacuum level of -600 mbar.
