3. A bi-directional filter uses:
  1. four check valves to direct flow through the element.
  2. filter elements that can take flow in either direction.
  3. two filters in one housing.
4. An airline lubricator introduces:
  1. a small amount of anti-freeze to the air line.
  2. a small amount of oil to the air line.
  3. a small amount of sealant to the air line.
5. Refrigeration type air dryers remove water from an air line by:
  1. a chemical absorbent action.
  2. a chemical adsorbent action.
  3. reducing the temperature of the air.
6. Off line filtration loops can be used to:
