🔍 Key Concepts

• Look at the internal stack of cone-shaped plates/disks in the rotating bowl section • Think about common fuel and lube oil cleaning equipment found in an engine room • Compare the shape and guards with typical machine shop tools like lathes and milling machines

💭 Think About

• Does this device appear designed to spin and separate liquids or to remove metal by cutting? • What is the purpose of the tall vertical spindle and enclosed casing around the rotating assembly? • Which of the answer choices would most likely be found in the engine room purifier space rather than in the repair shop?

✅ Before You Answer

• Identify whether the internal elements look like cutting tools and work-holding fixtures (machine tools) or multiple thin disks/plates (separating equipment) • Note the heavy protective housing typical of high‑speed rotating separators, not open machine tools • Ask yourself which option’s name best matches a device with a bowl containing many disks for liquid separation
