As an indication that an air compressor air intake filter needs to be replaced or cleaned, what statement is true?
AI Explanation
The correct answer is D.
A clogged or dirty air intake filter increases the air resistance, which results in the compressor having to work harder to draw in the same amount of air. This means the compressor will have to run for longer periods to meet the air demand. Additionally, the increased air resistance will cause the air intake pressure (measured between the filter and compressor inlet) to be more negative compared to a clean filter.
The other options are incorrect because they do not accurately describe the effect of a clogged air intake filter on the compressor's operation and the air intake pressure. For example, option A suggests the compressor would run for shorter periods, which is the opposite of what happens with a clogged filter.
