22 FABRICARE while the contaminants continue moving in a straight line and are captured in the drip leg. Various components after the tee provide the remaining pathways to conduct compressed air to the machinery. A ball valve is used to shut off the compressed air-flow from the drop to the machine, for maintenance; a combined filter/regulator provides another stage of contaminant removal along with filtration and air pressure regulation. Draining the drip legs can be done manually with a simple ball valve or automatically using a device known as a “drip leg drain.” I use an inexpensive air filter purchased from Harbor Freight (item #68279) plugged at the outlet side as a drip leg drain. I’m aware that in almost all cases the piping for the machinery already exists. Don’t plan to replace it because of this article. However, look at the diagram in the lower right of the illustration. It is very easy to just re-pipe the section at the end of the drop to the machine. Use soft copper tubing and compression fittings from the drop to the machine. Just having this section done properly will eliminate a great many problems. COMPRESSED AIR IS DANGEROUS! BEFORE ATTEMPTING ANY MAINTENANCE ON COMPRESSED AIR SYSTEMS, BE SURE TO BLEED OFF ANY AIR IN THE COMPRESSOR OR PIPING UNTIL THERE IS NO AIR PRESSURE LEFT IN THE COMPRESSED AIR SYSTEM. That’s it for now. Our next article will be about removing moisture from the compressed air system. Call me at (702) 376-6693 if you have any suggestions. I am always delighted to hear from readers.
