Worthington Corporation. REDUCED MAINTENANCE Without exception the Pydraul lubricants have proved to be outstanding in air compressor service. Life 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 are 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 2 and 3.) 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 inter-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 are 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 0621073 -1- z TOWOLDMONOQ39542 COMPARISON OF INDUSTRIAL AIR COMPRESSO Compressor Data: 142 CFM, 6" IP Bore, 5 I 500 HOURS ON PREMIUM PETROLEUM OIL -20621074 I TOWOLDMONOQ39543 VALVE DEPOSITS FROM TWO LUBRICANTS ' Bore, 5" Stroke, 870 RPM, 100 PSI Air, 500 HOURS ON MONSANTO'S PYDRAUL AC LUBRICANT 6210P5 3 k TOWOLDMON0039544 rise through these standard sight glass liquids. "Fluorochemical 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 No. A25849 or Manzell Part No. 82-1021-B. Modification of the Madison-Kipp lubricator requires replacement of the entire sight glass with their No. C-CV-300 oil feed indicator. Lubricators 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 Pydraul AC is safe to use in this application since its toxicity is of a very low order. Repeated or prolonged skin contact should be avoided, however. Accidental contact with 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.
