GENERAL INFORMATION Pydraul* AC is a thoroughly proven synthetic lubricant designed specifically to minimize two of the major problems associated with air compressor cylinder lubri cation; 1) Air compressor explosions and receiver fires, 2) Compressor maintenance due to deposit formation on exhaust valves and air system components. Fires and explosions in air compressors and compressed air systems are fairly common and can be very destructive to property and hazardous to personnel. Numerous theories have been proposed to explain the origin of these occurrences but there is still a wide divergence of opinion. On one point, however, there is general agreement; namely, that petroleum oil lubricants are directly involved. Apparently, oil mists and films gradually accumulate throughout the air system and these break down into com bustible gases and carbonaceous residues. (The latter are often as flammable as gun powder.) These materials can ignite, producing either an explosion or a receiver fire -- or both. Obviously, if such combustible materials could be removed from the system or pre vented from forming, fires and explosions could be eliminated. Substitution of a Pydraul fire-resistant lubricant for petroleum oil in air compressors will thus dras tically reduce explosion hazard. Monsanto's Pydraul lubricants are wholly synthetic products which have been widely used in diverse industrial applications for many years. Their high degree of fire re sistance has been conclusively demonstrated in actual use as well as in numerous laboratory flammability tests, Lubricating properties approximate those of SAE 30 lubricating oil. Hoth Pydraul F-9 and Pydraul AC work very well as air compressor lubricants. However, the latter was specifically designed for this service in order to reduce cylinder deposits to an absolute minimum. 2. "< ra o 52.-5i 5> AC t*?3 1" S A s2o9 3 -t oa PYDRAUL: RPg. U. 8. Pat.

Worthington Corporation. REDUCED MAINTENANCE Without exception the Pydread lubricants have proved to be outstanding in air compressor service, kite of piston rings, cylinders, and valves has been at least equal to---often better than- - that obtained with the use of premium quality petroleum lubricants. The carbon deposits frequently found on exhaust valves and air system piping arc significantly reduced when Pydraul lubricants are used. Pydraul AC, which was designed specifically as a fire-resistant air compressor lubricant, is particularly outstanding in this regard. This reduc tion in exhaust valve and air system deposits means a real saving in compressor maintenance costs, (See photos on pages l and ,V) EASY TO USE Conversion of compressors from petroleum to Pydraul lubricants is quite simple, For best results several points require attention. Since these fluids are excellent solvents for many petroleum lubricant residues, all intcr-stage equipment should be completely cleaned to prevent loosened deposits from passing into succeeding stages and causing malfunction or equipment damage. These fluids also soften or lift many paints and if in terior surfaces which will be contacted by the lubricant are painted, this paint should be removed prior to installation. On compressors which arc splash-lubricated from a crankcase, the above clean-up procedure is the only con version change required. If a separate force feed cylinder lubricator of the water/glycerine-filled sight glass type is used, the lubri cator must be modified. The Pydraul lubricants are heavier than water or glycerine and thus will not Continued on Page 4 0068319 | TOWOLDMON0021658 WATER_PCB-00006127 COMPARISON OF INDUSTRIAL AIR COMPRESSOI Compressor Data: 142 CFM 6 L.P Bore. 5 b 500 HOURS ON PREMIUM PETROLEUM OIL OO6&320 | TOWOLDMON0021659 WATER_PCB-00006128 os MARTIN SmiLA Roberts - 3 Coat Data -an Tech, Bultu, No, oyo- , ___ Title: Job: New Revised Dated / / Reprint Copies: ?rintlng Department: Please fill in cost data below from your Job sheet, then send this form to me.

"I'luorochetnical 101" a clear liquid supplied by Minnesota Mining & Manufacturing Company, has a higher density than the Pydraul lubricants and has proved to be a completely satisfactory sight glass liquid for use with these lubricants, Alternately, a simple metal bobber can be obtained for most of these lubricators. This is installed in the sight glass after draining the sight glass liquid and removing the guide wire. Operation of the lubricator is then indicated by movement of the bobber with each stroke of the pump plunger. Bobbers are available for either the McCord and Manzell lubricators as McCord Part \To. A25849 or Manzell Part No. 82-1021-B. Modification of the Madison-Kipp lubricator requires replacement of the entire sight glass with their NTo. C-CV-300 oil feed indicator. l.ubricators of the vacuum sight feed type can be used without alteration and have proved very satisfactory. USE RATE Field experience has proved that the required lubrication rate with the Pydraul lubricants approximates closely that of the normal petroleum oils. On an initial installation it is well to start with a somewhat in creased lubricant feed rate and reduce in successive increments until inspection of cylinder walls and valves indicates the proper degree of wetting by the lubricant. SAFE TO HANDLE Pvtlnnd AC' is safe to use in this application since its toxicity is of a very low order. Repeated or prolonged skin contact should he avoided, however. Accidental contact writh the eyes will result in moderate to severe pain and irritation but no permanent effects. In such an instance copious and prolonged washing of the eyes is recommended. To relieve irritation physicians have used 1% pontocaine solution as well as ophthalmic cortisone acetate solution. TYPICAL PROPERTIES OF PYDRAUL AC Viscosity (SUS) 50 F. 75 F. 100 F. 130 F. 210 F.
