Module for a vacuum pumping and/or abatement system

A vacuum pumping and/or abatement system comprising a plurality of modules, each module comprising:

• a top side and a bottom side opposite to the top side;
• a front side and a rear side opposite to the front side, the front and rear sides disposed between the top and bottom sides;
• two opposing lateral sides disposed between the top and bottom sides and disposed between the front and rear sides, wherein the top, bottom, front, rear, and lateral sides define a space;
• an apparatus located wholly within the space;
• and
• one or more connection points coupled to the apparatus, each connection point of the one or more connection points configured to receive an input for the apparatus or configured to receive an output from the apparatus;
• wherein
• the one or more connection points are located at the top side;
• the module has a maximum size in a first system dimension that is equal to a first integer multiple of a common fixed system value, the first system dimension being a dimension between the two opposing lateral sides;
• for each connection point, a respective distance between a respective connection point and a respective lateral side is a respective second integer multiple of the common fixed system value;
• and
• the common fixed system value is a value in the range 10 millimeters (mm)-200 centimeters (cm).
