Balancers are used to evenly distribute items over multiple belts or multiple belt lanes.

Belt balancers are usually used to balance multiple belts before or after train stations to ensure even loading of buffer chests and train wagons. They are also usually used to even out production by placing them in front of large machine arrays with multiple input belts. Belt balancers do not balance the individual belt lanes!

Lane balancers are usually placed after production to ensure that a belt is fully compressed or before consumption to ensure that both lanes of the belt are evenly drained.

Lane Balancers

Input Unbalanced, Output Balanced

These balancers evenly distribute the items onto the output lanes but do not "pull" evenly from the input lanes when the output is backed up. They are input unbalanced.

The last two balancers are a special case, they only work when there are items on only one side of the input belt.

Input and Output Balanced

These balancers evenly distribute the items onto the output lanes and "pull" evenly from the input lanes when the output is backed up. They are input and output balanced.

Belt Balancers

These belt balancers are all tested to be input balanced and output balanced. Throughput under full load is 100% and min throughput with blocked in- and outputs is also tested, it is noted when that is under 100%. Tests are done using this handy tool by d4rkpl4y3r on the Factorio Forums. When there are multiple versions of balancers that have the same stats but different sizes, the balancer with the smallest footprint is shown.


1 belt → x belts


2 belts → x belts


3 belts → x belts


4 belts → x belts


5 belts → x belts


6 belts → x belts


7 belts → x belts


8 belts → x belts
