The Castrol Hyspin™ AWH-M hydraulic oils are a range of shear stable high viscosity index lubricants.;Hyspin AWH-M has the following advantages when compared to conventional hydraulic oils (of the same class);High viscosity index and low pour point enables the product to be used over a wide temperature range.;Good shear stability which means no excessive loss in viscosity due to mechanical shearing.;Provides excellent wear protection for hydraulic pumps, helping to reduce downtime casued by unscheduled maintenance.;Excellent water separation and hydrolytic stability, measured by industry standard testing. This increases equipment reliability, helping to prolong the lubricant life and reduce downtime.;Good filterability gives a cleaner system with less frequent filter changes.
