This blueprint is a space optimized 30/s Fractionator row designed for use with stacked inputs with MK3 Proliferator. Tesla towers are included internally for easy tiling and space efficiency. Output will be very slightly lower than 30/s over time, but the space savings mean you can simply overbuild to make up for the small loss of production.

It can be used with lesser proliferation at a lower rate. Inputs should be stacked to 4 high before loading into the input.

The blueprint can be chained together, up to 4 times with MK3 proliferator for nearly 120 deuterium per second or nearly 7200 per minute from 1 input belt. While placing the blueprint, drag to tile it and press the - key to reduce the spacing. This will properly overlap the input belts to connect the rows together.

This blueprint is difficult to repair manually. The fractionators cannot be built when the output belt is already in place, and the output belt can only be placed between the fractionators by placing the belt as a blueprint. Be careful when flying or landing near these fractionators, as having to delete a fractionator to free yourself from being stuck between them can be a real pain, especially reconnecting the fractionators to the output belt when they are deep in a dense grid.
