Sinopec 4506 Synthetic Compressor Oil is a line of lubricants blended using fully synthetic polyalphaolefin (PAO) base oils and selected additives, including antiwear and extreme pressure (EP) additives and rust and oxidation inhibitors. Designed for use in both rotary (especially centrifugal and screw) and reciprocating air compressor applications, it is available in three viscosity grades: ISO 32, 46 and 68.

  • Sinopec 4506 Synthetic Compressor Oil is suitable for use in:
  • Small, medium or large, single- or multi-stage reciprocating or rotary air compressors (especially rotary screw and centrifugal types) in a variety of industries (e.g. the iron, cement, chemical, manufacturing and electronics industries).
  • Rotary air compressors where the operating temperature range is between –50°C and 120°C.
  • Reciprocating air compressors where the operating temperature range is between –40°C and 200°C (or up to 220°C for short periods).

Caution: not recommended for breathing air compressors.



The synthetic base oil shows outstanding thermal and oxidation stability and low carbon-forming tendency compared
with conventional mineral oil-based products, and this leads to good compressor cleanliness, reduced deposits and
improved compressor efficiency, even when air discharge temperatures are high (up to 220°C in reciprocating

Reduced deposits in discharge lines minimise the risk of fires and explosions.

Good lubricating and antiwear/EP properties protect moving compressor parts against wear and extend component

Excellent heat conduction properties reduce the system operating temperature and extend oil life.

Good anti-rust and anticorrosion properties protect cylinders and discharge valves from rusting and corroding,
enhancing equipment life and performance, and prolonged service intervals.

Good water-separation characteristics ensure that condensed water vapour can easily be separated from the lubricant and prevent the formation of emulsions (which could block the oil/air separator (coalescer) in some compressors), therefore prolonging coalescer life, and reducing equipment downtime and maintenance costs.

Improved oil quality leads to longer maintenance and overhaul intervals and extended oil drain intervals (6,000 to 8,000 hours).

High viscosity index ensures excellent temperature–viscosity properties, and ensures wide operating temperature

Good anti-foam properties and compatibility with common seal materials prevent oil leakage from the system during
