The Particle Filter is the first step of the Particle Filtration system. Once built in one one of the caverns this machine requires 15 PPS in order to filter out Freezon from the Cold Cavern, Chlorine from the Toxic Caverns and Sulphur from the Magma Caverns.

The filter can store up to 100 of any of these gasses and passes them to a Particle Compressor that is either directly connected to one of it's 4 output ports or that is connected to a port through Fluid Pipes.

Requires operational C3 system in the cold cavern to function
