In the lower image, 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. Even though industry has trended toward using non-lubricated air, the benefits of using an air lubricator are undeniable.

IAC's fluids are highly engineered to provide optimum performance and energy conservation and the “same as” fluids just don’t match up. ISO specifies hygiene requirements for the formulation, manufacture, use and handling of lubricants, which may come into contact with products during manufacturing or processing. The international standard applies to lubricants intended air end, air & lubricant compressor for use in food production, as well as cosmetic, pharmaceutical and animal feed industries. NSF ISO Certification by an independent, third party provides Summit with a means to obtain international acceptance for their products. The delivery of clean inlet air to the compressor to prevent contamination of the lubricant and corrosion of the system should be a main focus.

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.
When particulate is the concern, analytical ferrography is one simple and useful technique for differentiating between these three sources. High Particulate - If the corrosion particles are mostly small particulate, the filters should be changed and measures should be taken to determine what acidic condition is causing the corrosion. pH - A rapid or excessive decrease in pH indicates ingestion of acid gases or other contaminants from the environment. This will require a fluid change, but also indicates that the source of contamination needs to be eliminated. It is not compatible with silicone-based fluids, such as Sullair’s 24KT.
Table 3 offers some possibilities for explaining the presence of various elements in compressor fluids and the significance of those elements. Figure 2 demonstrates the various types of ferrous particulate that can readily be distinguished by analytical ferrography.

SAP 8000 series is specially formulated as a direct equivalent for major OEM rotary screw PAG coolants. The formula is derived from the same philosophy used for those OEM PAG coolants with approximately 73% polyalkylene glycol and 17% pentaerythritol ester. This fluid is designed for 8,000 hours and has excellent heat transfer, a high flash point and resists both varnish as well as oxidation. The International Organization for Standardization sets forth worldwide standards for proprietary, industrial and commercial purposes. Depending on the ultimate air purity , compressors can be ranked from ISO Class 0-5. The original version of ISO compressed air purity standards was ‘made by and made for’ the filter manufacturers.
The answer depends on specifics such as the type of compressor, the application and the operating conditions. Running your compressor at high temperatures for extended periods of time will cause your oil to form a thin layer throughout the inside of your compressor. Consequently, the compressor’s oil cooler will not be able to work properly, resulting in even higher temperatures and eventual compressor shutdown. The result is greatly reduced friction, heat and wear.Learn more about Monolec.
In addition, the lubricant must be chemically compatible with the refrigerant, and must have a pour point lower than the minimum temperature to which it will be exposed in service. With any compressor system, it is important to follow the manufacturer's lubricant recommendation.

Since 1924, Ingersoll Rand has been building extremely durable and reliable hoists, winches and ergonomic systems. Built tough to work in the harshest environments, count on Ingersoll Rand for lifting products that are Beyond Tough. The operating compression principle involves two intermeshing spirals or scrolls, one scroll being stationary and the other orbiting in relation to the stationary scroll.
Once the unit has operated for hours at operating temperature, the entire load of lubricant needs to be drained and discarded. By the time this foul smell begins to manifest itself, the TAN is very high. In order to prevent a compressor failure, the lubricant needs to be drained.
