Premium Longlife

The Castrol Hyspin™ AWH Superclean hydraulic oil range with Viscosity Index improver (VI) is based upon highly refined mineral oil enhanced with a stabilised zinc additive system and filtered to ISO class - /14/11.

Hyspin AWH Superclean has been specially formulated to provide good anti-wear and thermal stability performance.
The careful blend of additives with a high quality base stock ensures that Hyspin AWH Superclean has excellent
hydrolytic and oxidative stability while exhibiting a minimal tendency to produce sludge and deposits. In addition, Hyspin AWH Superclean provides corrosion protection to ferrous and yellow metal components found within a hydraulic system.


This range is designed for use in industrial hydraulic systems which require anti-wear protection. It meets the needs of hydraulic equipment operating under severe service conditions such as a wider temperature and high pressure applications.


The Hyspin AWH Superclean range is fully compatible with elastomer materials commonly used for static and dynamic
seals, such as nitrile, silicone and fluorinated (e.g. Viton) polymers.

Hyspin AWH Superclean is classified as follows:
ISO 6743/4 - Hydraulic Oils Type HV
Hyspin AWH Superclean grades meet the requirements (for appropriate viscosity grade) of: DIN 51524 Part 3

Advantages

  • Good thermal and oxidative stability leads to longer operating life, reduction in lubricant costs and minimises
    deposit formation giving a cleaner system.
  • Excellent anti-wear performance gives wear protection and reduces downtime from unscheduled maintenance.
  • Good filterability characteristics (including in the presence of water) enables cost savings to be made from
    increased filter life and reduced maintenance.
  • Excellent water separation and hydrolytic stability means reduced down time through prolonged lubricant life and increased equipment reliability.
  • High Viscosity Index. Minimum change in viscosity over wide temperature range.
  • Proven additive system. Ensures maximum protection from wear, corrosion, foaming and oxidation.
  • Increases the service life of hydraulic systems.
