Further difficulties are high exhaust temperatures resulting from mal-function of valves and high cylinder temperatures that cause varnish deposits on cylinder rings and walls. With years of experience in the synthetic lubricant field behind them, Monsanto researchers sought the answer to this plaguing problem. After testing many types of fluids, they found a fire-resistant lubricant that proved to be ideatly suited for air compressors. They called it Pydraul AC. Pydraul AC reduces exhaust valve and air compressor piping deposits to a minimum in all types of air compressors. Fewer carbon deposits on exhaust valves and in interstage equipment means a substantial savings for the operator who must pay the cost of cleaning as well as the cost of down time on the equipment. Lower maintenance cost alone usually justifies the use of Pydroul AC in air compressors. rsi removes explosion threat There are nearly as many theories as there are men voicing opinions as to why fires and explosions happen in air compressor systems, but one point is generally agreed upon: petroleum oil lubricants are directly involved. r Apparently, oil mist and films gradually accumulate throughout the air system. These break down into combustible gases and carbonaceous residues that can ignite to produce an explosion or receiver fire, or both. Pydroul AC has proven its ability to reduce these hazardous residues to an absolute minimum or eliminate them completelyl By minimizing residues, Pydraul AC effectively reduces the threat of compressor fires and explosions. And Pydraul AC is fire-resistant It provides safe operation, protecting not only the equipment, but the lives of workers as well. fTBMUL: MONMNta TMPIMM. (. U.l. TAT. OPT.

They can occur in small compressors operating at 50 psig. and in large installations operating at very high pressures. There is no pattern, no way to predict the safety of a particular compressor operation. Such explosions and fires are considered infrequent by some people In fact, an air compressor operator might go along for years without an accident. However, when they happen, these explosions and fires can blow entire compressor systems apart and even rip yard piping out of the ground. The cost for equipment loss and down time from these accidents can be staggering. Fire-resistant Pydraul AC essentially eliminates the basic cause for most fires and explosions by minimizing the carbon deposits. Its superior oxidation resistance adds to its ability to reduce explosions: by resisting burning in air, Pydraul AC holds the explosion threat to a minimum.

The statement of a lubricating engineer quoted below J typifies its reception as a lubricant. The compressor was a Cooper-Bessemer JM-5 located in a large Midwestern plant. J "Lubricating properties of Pydraul AC have been very satisfactory. Wear measurements on Molypak rings J taken approximately five months later indicate 0.003" wear. This is normal and considered very good. No corrosion of cylinder liners, valves and piping has been experienced, and service is very satisfactory." J .........

Deposits formed from the 5(N)-hour operation on petroleum oil were removed before the valve began operating on Pydraul AC so the valve was perfectly clean before each operation. A glance at the photo on the left shows that a considerable amount of carbon formed in the normal 500-hour take-down period for petroleum oil. The photo on the right shows the great improvement when the valve operated 500 hours on Pydraul AC. In this particular case, the compressor operator expects to get 7500 to 10,000 hours of service from Pydraul AC without shutting down--a 15- to 20-fo!d increase of operating time without a shut-down. That's a substantial saving of time and money due to Pydraul AC. .1 TOWOLDMON0025667 WATER_PCB-00010136 0220968 PYD RAUL AC AS CURRENTLY IN USE AS A LUBRICANT IN AIR COMPRESSORS MADE BY THESE MANUFACTURERS...

Extensive field experience has proven that the required lubrication rate with Pydraul AC closely approximates that of petroleum oils. When installing new equipment, it is well to start with an increased lubricant feed rate and reduce by successive increments. Inspection of cylinder walls and valves indicates the proper degree of wetting. On installations converted from petroleum oil to Pydraul AC, the same feed rate as for the petroleum fluid should be adequate. r\ W.. v 0 yr ' 'J Wk / 0V \ v-' "|'fj t / s// \] TOWOLDMON0025669 WATER_PCB-00010138 CONVERTING TO PYD^UL AC IS EASY t L c! The conversion of air compressor systems from petroleum lubricants to fire- and explosion-resistant Pydraul AC is simple, but one procedure is vitally important to insure smooth, efficient operation with Pydraul AC. Exhaust valves and interstage equipment should be thoroughly cleaned before installation, because Pydraul AC will loosen carbonaceous deposits, which may cause unnecessary maintenance down-time and production loss. Once the valves have been thoroughly cleaned of harmful carbon deposits, Pydraul AC keeps them clean--lets you run longer between maintenance shutdowns. standard check for compressors plastic separator bowls Not all plastic separator howls are suitable for Pydraul AC service because certain plastics are "crazed" or softened when exposed to it. Though separator bowls can be molded of plastics that are totally resistant, for the present it is safest to use glass, brass or steel bowls. If there is a question as to the resistance of a particular plastic, Monsanto will be happy to advise if the material is suitable. diaphragm valves Pydraul AC has a softening effect on the "Neoprene" or Buna N rubber diaphragms that are normally used lor petroleum oil service. These rubbers should be replaced with butyl rubber material which is resistant to Pydraul AC. Butyl diaphragm sheeting is available from normal sources of supply. All diaphragms in unloading valves or downstream control valves should be replaced at the time of changeover. Diaphragms in valving downstream from separator systems or drying systems need not be replaced at changeover time, but should be changed on a preventive maintenance schedule as soon as practicable after operation on Pydraul AC is begun. r r r TOWOLDMON0025670 WATEFLPCB-00010139 0 t60ZZ o<rO special check for splash-lubricated compressors (M .3 crankcase paint Since the paint used on crankcase interiors of some compressors will in m<st cases ho softened and ' i eventually removed by Pydraul AC, the paint should be removed.

Pydraul AC is heavier than water or glycerine and will not rise through these standard sight-glass liquids. "Fluorochemicnl 101," a clear liquid supplied by the Minnesota Mining and Manufacturing Company, has a higher density than Pydraul AC and is a completely satisfactory replacement. metal bobbers The alternate to using "Fluorochemical 101" is to modify the sight-glass lubricator by inserting a simple metal bobber. The bobber is installed by draining the sight-glass liquid, removing the guide wire and inserting the bobber. Operation of the lubricator is then indicated by movement of the hohlier with each stroke of the pump plunger instead of counting the drops as with guide wires. Boblx*rs are available for either McCord or Manzell lubricators as McCord part number A2584!) or Mnnzell part numlxr 82-1021-B. Modification of the Madison-Kipp lubricator requires replacement of the entire sight-glass with their number C-CV-300 oil feed indicator. 1 vacuum-sight lubricators Vacuum-sight lubricators require no modification for Pydraul AC usage.
