Our Small Filtration Silo features a small cylindrical silo stack supported by 2 large stanchions and features a 'metal' stairway up to the platform gantry to allow figures to be placed on.  The ribbed surface of the silo gives an unusual Sci-Fi appearence. It has an extruding pipework outlet attatched to the silo and comes complete with a removable valve and flange capping.  This allows extension pipework to be added to this particular silo if required.
