Try not to take your CMM's air from the lowest point in the line. Take the air above the lowest point preferably in a straight run down towards the floor. This will allow much of the water, oil and such to fall past your CMM air. You will how ever need to have a way to drain this lower section as just letting it fill up defeats the purpose. Running the line into a 5 gallon bucket with a lid will not only contain but also conceal the contaminates and allow you a means of removing them from the area. Just put a manually operated valve between the CMM air and the bucket "that you open to drain daily" and you will help improve your CMM's air quality.
The lowest point in our air line has a ball valve for draining liquid, about 3 feet above the ball valve is a T fitting where our regulator is attached. Our air line drops down from the ceiling.
