Condition Monitoring Standards

Visual Inspections- Des-Case Breather

Check the color of the breather.

Blue color means that the breather is still active, while red means it is saturated and not drying air anymore.

The air filter will remove both dirt and moisture.

The red color means that the filter is saturated with water and dirt.

Yellow or brown means it is saturated with oil molecules or mist.
