Description

The Castrol AlphasynTM EP gear oil range of high quality synthetic lubricants are based on poly-

alphaolefin (PAO) fluids ａnd sulphur/phosphorus Extreme Pressure (EP) additive technology providing 
good thermal stability ａnd high load carrying capacity.

Application

The Alphasyn EP range have been formulated for use in all types of enclosed gears including heavy 
ａnd shock-loaded gears ａnd bearings where EP properties are required. 
They are suitable for use in gear boxes where micro-pitting resistance is required ａnd for a wide range 
of applications in extreme environments, for example mining ａnd quarrying, marine applications and 
paper production. 
The use of a PAO base stock provides an inherently high Viscosity Index (VI) ａnd low pour points 
making these products suitable for use over a wide temperature range.

The Alphasyn EP range is fully compatible with nitrile, silicone ａnd fluropolymer seal materials.

Alphasyn EP is classified as follows: 
DIN Classification is CLP

The Alphasyn EP range meets the requirements of: 
     *  DIN 51517 Part 3 
     * AGMA 9005 - D94 
     *  US Steel 224 
     *  David Brown Type E 
     *  Hansen Transmissions

 Flender 
     *  Lohmann & Stofferfoht

Advantages

     *  Full EP performance* gives maximum protection of gears against wear ａnd shock loading, 
          including protection against micro-pitting. 
     *  Good thermal ａnd oxidative stability provides reliable operation ａnd extended operating life 
          when compared to mineral oil based products. 
     *  High corrosion protection for gears. 
     *  Inherently high Viscosity Index (VI) makes the product suitable for operations over a wide 
          temperature range. 
     *  Rapid air release ａnd good performance in the Flender Foam Test prevents foaming and 
          bearing damage. 
     *  Good water separation ａnd demulsification characteristics means reduced down time through 
          prolonged lubricant life ａnd increased equipment reliability. 
     *  PAO based lubricant provides good compatibility with seals, paints ａnd mineral oil based 
          lubricants.

* ISO 320 grade achieved FZG >14 rating under A16.6./90 (double speed) test conditions
