Features and Benefits

• Long oil service life: Oil maintenance intervals of up to 4,000 hours may be possible where permitted by the compressor manufacturer and supported by operating conditions.

• Deposit control: Helps minimise carbon deposits in vane slots and deposits on rotating screw components.

• Wear protection: Helps protect compressor bearings and gears.

• Thermal and oxidation stability: Helps resist lubricant breakdown and maintain internal cleanliness.

• Rapid air release: Helps reduce air retention in the lubricant.

• Good water separation: Helps separate condensed water from the oil.

• Foam control: Supports reliable compressor lubrication and operation

  Applications

  • Oil-flooded or oil-injected rotary screw air compressors.

  • Rotary sliding-vane air compressors.

  • Single-stage and two-stage rotary compressors, where specified by the manufacturer.

  • Compressor systems operating under elevated discharge temperatures and pressures within the product's recommended limits.

  The manufacturer indicates suitability for certain vane compressors operating at pressures up to 10 bar and rotary compressors up to 20 bar, with air discharge temperatures up to 100°C under specified conditions.

    Storage and Handling

    • Store in sealed, clearly labelled containers in a clean, dry location.

    • Prevent contamination by water, dust and other lubricants.

    • Follow the compressor manufacturer's oil-change and maintenance recommendations.

    • Although intervals of up to 4,000 hours may be possible, actual service life depends on temperature, humidity, compressor design and operating conditions. Oil analysis can help determine the appropriate drain interval.

    Health and Safety

    Consult the current Safety Data Sheet (SDS) before use. Avoid prolonged skin contact and use suitable protective gloves when handling used oil. Wash skin promptly with soap and water after contact. Dispose of used oil through an authorised collection facility; do not discharge it into drains, soil or waterways.
