SF-510 | SYNTHETIC COMPRESSOR OILS

GENERAL DESCRIPTION:

SELCO SF-500 is a synthetic fluid designed to meet the needs of rotary, screw and reciprocating air compressors. The product exhibits excellent high temperature properties coupled closely with outstanding oxidation resistance. Currently available lubricants often compromise on compressor requirements, for example reciprocating units using automotive crankcase oils formulated to MIL specifications can suffer from heavy carbon and ash deposits on valves, SELCO products, on the other hand, are formulated solely for compressors.

 

RECOMMENDED USAGE:

SELCO SF-500 is a synthetic compressor lubricant compatible for Rotary Screw & Reciprocating Air Compressors. It is fully miscible with conventional mineral oils. If accidentally mixed with mineral oils, some reduction in the superior performance characteristics of the synthetic lubricant may occur. However, the lubricant can remain in service until a convenient system change is possible.

ADVANTAGES:

  • Reduce carbon formation and the risk of explosion, and increase safety
  • Virtually eliminate varnish and sludge deposits, ensuring that items such as oil/air separators in rotary. Compressors function efficiently at all times.
  • Provide better demulsibility, which is needed for rapid and complete water separation (this is particularly important for oil flooded compressors, where condensate can accumulate in oil receivers)
  • Extend oil drainage intervals up to 8000 hours or 12 month’s operations.
  • Outstanding operating temperatures range which will affect operating economics in compressor down time and lubricant utilization. Good compatibility with elastomers used as seals in reciprocating compressors.
  • Reduce oil consumption and carry over by virtue of their low volatility and good lubrication properties.
  • Maintain the high efficiency of reciprocating compressors by significantly reducing valve deposits.
  • Reduce maintenance costs by reducing wear and deposits associated with the use of mineral oils, savings on replacement parts and labour can be achieved.
  • Improve oil receiver and crankcase performance by virtue of their low foaming properties.
