Petronas Compressor A M4 Series




Having been designed to meet and surpass key industrial requirements, the PETRONAS Compressor A M4 Series of compressor oils can be used in service for as long as 4,000 hours, even with maximum discharge temperatures as high as 100°C.

These oils are based on carefully chosen high-quality mineral base oils combined with additives to combat wear, oxidisation, foam, and rust. The A M4 Series also offers enduring performance thanks to high oxidation and thermal stability, and high levels of deposit and varnish control.

The series is recommended for use in both mobile- and stationary-based compressors, as well as rotary vane, rotary screw and reciprocating compressors that have crucial bearings and gears.

The series brings the benefit of being highly compatible with the majority of metal alloys, elastomers and seals, thus helping to ensure reliable performance and avoiding oil contamination and leaks through degraded seals. Performance is also maintained even under high pressure and temperature thanks to high oxidation and thermal stability, meaning oil drains are needed less frequently.

The PETRONAS Compressor A M4 Series can also help extend the longevity of equipment by protecting components from unnecessary wear and maintaining a high level of internal cleanliness for surfaces by controlling deposit and varnish formations and inhibiting corrosion processes that lead to rust. It also protects against the degenerative effects of air and water thanks to very good water separability and high levels of fast air release and foam stability, thus helping to lower maintenance costs and ensuring smooth, reliable operation.
