Never mount oil and water extractor on or near the air compressor.
During compression, air temperature is greatly increased. As the air cools down to room temperature, moisture condenses in the air line, on
its way to the spray gun. Therefore, always mount the oil and water extractor at a point in the air supply system where the compressed air
temperature is lowest.
Drain air lines properly.
Pitch all air lines back towards the compressor so that condensed moisture will flow back into the air receiver where it can be drained off. Each
low point in an air line acts as a water trap. Such points should be fitted with an easily accessible drain. See diagram above.
