🔍 Key Concepts

• Purifier (centrifuge) bowl assembly layout from top to bottom • Function of the disk stack in separating fuel and water • Difference between separating (top/intermediate) disks and the bottom and paring components

💭 Think About

• Look at where label I is pointing in relation to the whole stack of disks—does it point to a single part or the entire stack? • Ask yourself which parts of a purifier actually perform the separation of oil and water versus which parts only collect or discharge the separated liquids. • Consider how the names "top," "intermediate," "bottom," and "paring" would logically relate to vertical position and function in this cutaway.

✅ Before You Answer

• Verify exactly what region the arrow for I covers: just the uppermost plate, or the main group of similar plates. • Distinguish between the fixed paring device near the outlet passages and the rotating disk stack itself. • Confirm which component at the very base of the stack is identified separately elsewhere in the figure as the bottom disk.
