In pneumatic lubrication, what carries the lubricant from the lubricator to the point of use?

• A. Return line
• B. Lubricant line
• C. Electrical signal
• D. Air flow

Answer: (D)

In pneumatic lubrication, the lubricant is carried to the point of use by the flow of the compressed air. The lubricator injects a controlled amount of oil into the airstream, and as the air moves through hoses and to cylinders or valves, it transports those oil droplets along with it. This means the air itself is the carrier that delivers lubrication to where it’s needed. A return line or a separate lubricant line isn’t typically used to transport the oil over distance, and electrical signals don’t move the lubricant either.
