Morphology
The meaning ('a device that removes dust and other fine particles from gases using electrostatic charges') is directly compositional from 'electrostatic' (relating to static electricity) + 'precipitator' (an agent that precipitates or removes particles). Although the term is technical, the adjective+noun structure clearly signals a device that uses electrostatics to precipitate particles, so a B1 learner who knows both constituents can infer the meaning.
Etymology
Electrostatic precipitator gets its name from how the machine works: it gives tiny dust particles an electric charge so they stick to metal plates and fall out of the gas. The word electrostatic means 'electric charge' and precipitator comes from a word meaning 'to fall', so the name describes 'a device that removes dust from gas'.
