Morphology
The noun combines two literal, semantically transparent constituents: 'filter' (device removing impurities) and 'press' (machine exerting pressure), so the meaning 'a machine that presses to filter/separate solids from liquids' is directly inferable. This is a compositional, technical compound that follows normal English noun-noun formation and is cross-linguistically transparent, so a B1 learner who knows both words would likely understand it.
Etymology
Filter press comes from the machine's action: many cloth filters are put in a row and then pressed together so the liquid is 'squeezed' out and the solids stay behind. That's why a filter press means a machine that 'separates' solids from liquids by pressing.
