Hyspin™ AWS
Castrol Hyspin™ AWS hydraulic oil range is based upon highly refined mineral oil
enhanced with a stabilised zinc additive system. Hyspin AWS has been specially
formulated to provide good anti-wear and thermal stability performance using
proven additive technology. e careful blend of additives with a high-quality
base stock ensures that Hsypin AWS has excellent hydrolytic and oxidative
stability while exhibiting a minimal tendency to produce sludge and deposits.
Additionally, Hyspin AWS provides corrosion protection to ferrous and yellow
metal components found within a hydraulic system.
is range is designed for use in industrial hydraulic systems which require anti-
wear protection such as lightly coated gears variable speed units and bearings.
Advantages
Hyspin AWS has the following advantages when compared to conventional hydraulic
oils:
• Good thermal and oxidative stability. Oxidative stability reduces deposit
formation, resulting in a cleaner system. is can extend the machinery's
operating life.
• Excellent anti-wear performance increases wear protection, which can help
reduce downtime caused by 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, measured by industry standard
testing. is increases equipment reliability, helping to prolong the lubricant's life
and reduce downtime.
Applications
Hyspin AWS is classified as follows:
• DIN 51502 classification - HLP
• ISO 6743/4 - Hydraulic Oils Type HM
