We took our previous knowledge and combined it with what he taught us to produce the below information. Good demulsibility makes water removal easier, reducing the risk of water-related problems. Adequate pour point and flash point — These ensure that the lubricant will maintain proper flow and operate safely across the application’s full temperature spectrum.
Air compressor oils & lubricants are specifically formulated to lubricate various mechanical parts while cooling them down and protecting from corrosion. SAP 6000 series utilizes proprietary base stocks to provide the ultimate in synthetic lubricant performance for rotary screw air compressors. It combines excellent corrosion protection, long air dryer and filter life, and energy efficiency with varnish-free performance. This fluid provides the extra protection needed to run in high operating temperatures or applications exceeding 8,000 hours between fluid changes. Versatile multifunctional Multilec Industrial Oil provides superior long-term anti-wear protection in variety of compressor applications.

In part, the standard mandates that compressed air exhaust may not exceed 4.32 ppm of oil mist contamination in any 8-hr work shift of a 40-hr work week. In this circuit, the lubricator bypasses the control valve and lubricates the cylinder only while its rod retracts. When the rod extends, exhaust air from the rod end of the cylinder lubricates the directional control valve.Air flow has a big influence on the type of lubricator that should be specified. Chevron Compressor Oil 260 is used to lubricate compressors in hydrocarbon service. As a professional Havoline installer, leverage the quality and trust of the Chevron brands and products as well as support for your business by a team of industry professionals. Refrigeration compressor lubricants are miscible with the refrigerant, chemically inert, and able to function at low temperatures. Gas compressor lubricants resist dilution by the gas being compressed.
By the time this annual change takes place, the TAN could easily be 15. Usually there is serious corrosion of the compressor leading to air end failure. First, when oil in a compressor is drained normally, about 10% of the lubricant remains in the lines, in the cooler, or in the bottom of the sump. If someone changes the oil and the TAN is 2.0, and if took 12 months for it to reach that mark, then the oil that has remained will contaminate the new oil. The TAN this time will reach 2.0 in 10 months and it may hit 4.0 by the time the annual oil change takes place. Air tool oil is too thin to support the demands of the compressor. It may be cheaper than some of these alternative options that we discussed.
If it doesn’t close automatically, or if it doesn't release air when pulled, replace the valve. In order to prevent high acid levels from recurring, compressor operators should obtain a sample of the lubricant at least every 4,000 hours. Firms like Air Engineering and others will perform free laboratory analysis.

Automatic lubricators are used for hard-to-access greasing ports, where the motors themselves are inaccessible, and/or if maintenance personnel are not always on site or available to perform this necessary task. See Timken and Machinery Lubrication for more information on automatic lubricators.
Make sure the lab is aware of fluid type and application, so that water level limits can be set accordingly. In cases where the fluid quantity justifies it, rotating pressure vessel oxidation test can reveal the remaining useful life of a PAO-based fluid. With polyglycols these steps are not necessary, because AN is a reliable indicator of the remaining fluid life. Contaminants - Hydrocarbon contamination is typically monitored to assure that operators are not mixing fluid types. Air can be tested by suspending corrosivity coupons of copper and silver in the air near the compressor. After a specified period, laboratory analysis of the resulting compounds on the surface of the coupons will reveal the type of contaminant in the air and the degree of contamination. The fresh lubricant serves to flush contaminants through the system with a protective effect, even though these compressors have a high lubricant consumption.

PETRO-COMP FG-46XL lubricant provides maximum wear protection and excellent lubricity compared to other H-1 food grade synthetic oils allowing 50% to100% increase in lubrication service life. LUBRIPLATE AC-0, AC-1, AC-2 & AC-2A Air Compressor Oils are dual-purpose or multi-functional lubricants for use in air compressors, hydraulic systems and oil recirculating systems. SAP 2000 series is a synthetic blend lubricant designed for reciprocating and rotary screw compressors. This product offers extended drain intervals compared to petroleum oils and reduces carbon and varnish buildup, lowering maintenance costs. High thermal and oxidative stability — These properties help support a long service life for the lubricant.
Compressor OEMs have developed computerized control systems to continually monitor and adjust to maximize savings. The temperature at which a fluid is rated for its nominal life, typically 8,000 hours for most polyglycol, ester or PAO compressor fluids, will vary. A fluid rated for 8,000 hours at 200°F would be expected to significantly outlast a fluid rated for 8,000 hours at 180°F. The fluid will easily remain below 0.5 percent water content with no free water, but high temperature is detrimental to fluid life. Every 18°F (10°C) increase in temperature will reduce fluid life by approximately half.
