Pennine HM AF Hydraulic Oils are Zinc free fluids developed for use in most hydraulic power andcontrol systems. Manufactured from heat stable high viscosity index solvent refined base oils, theyincorporate Zinc free, ashless additives to improve the anti-wear performance, oxidationresistance, protection from corrosion, air release and anti-foaming tendencies. These oils whencompared to conventional hydraulic oils have better hydrolytic stability, demulsability andfilterability whilst maintaining good antiwear performance for pump and gear protection.ApplicationsSuitable for most hydraulic power systems where reciprocating or rotary fluid pumps are used, including reciprocating and axial piston units, rotary gear, and vane pumps. Their main applicationsare found in areas where water contamination is possible, in equipment containing silver platedcomponents and in other applications where the use of a Zinc free oil is required however they arealso suitable for use where conventional hydr
