Castrol® Hyspin™ AWS
Anti-wear hydraulic oil
Castrol Hyspin™ AWS hydraulic oil range is based upon highly refined mineral oil enhanced with a
stabilized zinc additive system.
Castrol Hyspin AWS has been specially formulated to provide good anti-wear and thermal stability,
performance using the very latest additive technology. The careful blend of additives with a high quality base
stock ensures that Hyspin AWS has excellent hydrolytic and oxidative stability while exhibiting a minimal
tendency to produce sludge and deposits. In addition, Hyspin AWS provides corrosion protection to ferrous
and yellow metal components found within a hydraulic system.
This range is designed for use I industrial hydraulic systems which require anti-wear protection. It is also
suitable for other duties in which lubricants of high oxidation stability and lubrication performance are
required, such as nitrite, silicone and fluorinated (e.g. Viton) polymers.
The Hyspin AWS range is fully compatible with elastomer materials commonly used for static and dynamic
seals, such as nitrite, silicone and fluorinated (e.g. Viton) polymers.
Castrol Hyspin AWS is classified as follows:
DIN 51502 classification – HLP
ISO 6743/4 – Hydraulic Oils Type HM
• Good thermal and oxidative stability leads to longer operating life, reduction in lubricant costs and
minimizes deposit formation giving a cleaner system.
• Excellent anti-wear performance gives wear protection and reduces downtime from unscheduled
• Good filterability characteristics (including in the presence of water) enable 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.
