The Particle Filtration System is the combined gathering and processing of gas from a series of four Tier 4 machines that allow for the output of compressed gas cylinders. The machines required for the output of usable gas are the Particle Filter, Particulate Compressor, Particle Storage, and the Gas Bottler.
Each machine comes with four output ports on the bottom. These can be connected to the next machine in the series by using a fluid pipe and a machine can have multiple outputs connected to itself. However, bear in mind that machines will not accept input from anywhere on it's side - for example in the current version connecting an input to a Particle Compressor in the center-top block will not result in a connection.
Additionally, if the machines are stacked on top of each other, they will connect without the need of pipes at all.
