THERE ARE MANY REASONS FOR USING SYNTHETIC AIR COMPRESSOR LUBRICANTS
These include: Compressed gas purity is crucial when the gas is used in a chemical process or for potential human consumption. Only the highest quality base fluids can be used to lubricate these compressors. Oiltech has a range of compressor lubricants which is suitable for inert processes and industrial gases including natural gas, hydrogen, helium, carbon dioxide, etc.

Compressor and Synthetic Compressor Lubricant Selection Continuous high temperatures prevalent in the
cylinder during the compression cycle justify the use of synthetic fluid
in the cylinder. On a single stage compressor at a discharge pressure of
6.9 bar, temperatures are found to be as high as 260°C. In air cooled compressors, the bulk of the lubricant
can be exposed to temperatures approaching 121°C. For this reason,
petroleum based lubricants require fairly frequent change-outs. Changes
occur in the range of 500-1000 hours. Rotary vane type compressors require an anti-wear
lubricant for minimization of wear in contact surfaces. Data currently
developing in the field indicate an increasing need for anti-wear
lubricants in rotary compressors of the screw type. Since both types
produce an intimate mixture of air and lubricant during operation, high
oxidation stability is a requirement. After compression, the lubricant
must be separated from the discharge air and returned to the lubricant
reservoir. Lubricant integrity must be maintained to insure complete
isolation of the air and lubricant phases. Many air compressor manufacturers have evaluated the
performance of synthetic based lubricants and are currently recommending
their usage in a wide range of applications. Increased usage by consumers further reflects
acceptance. Changeover procedures have been established by compressor
manufacturers, working on established programs with lubricant suppliers. The attached article attempts to give an outline
regarding the fundamentals of various air compressors and synthetic
lubricants. It hopes to give the users of air compressors additional
information to guide their selection of an optimum compressor and
lubricant for their application. Oiltech Australia markets a complete range of
synthetic fluids for industrial applications. The attached Oiltech
Synthetic Air Compressor Lubricant Chart gives a thumbnail guide regarding
our product selections for various compressors. |
