Vacuum pump and resin trap setup. The main vacuum pump is not in this photo, while standing outside the building, on the lower left corner (partly visible) the back up vacuum pump, then two big resin traps with vacuum gauge, above that a long pvc drain pipe that is actually collecting the superfluous resin at this moment, and replaced the first pvc drain pipe (horizontal on the right) who is off line at the moment while draining collected resin in an old mortar shell, in the background the back up power generator.
