Estimated Guardian Element Life and Cleanliness Levels
The following chart shows typical element life
(in gallons of oil passed) and cleanliness levels
achieved by standard Parker elements available with
the Guardian. Some assumptions have been made.*
*
1. New oil is at ISO 22/20/16.
2. No environment or work ingression.
3. Single pass oil transfer.
NOTE: Data for fluid transfer only. For continuous fluid
polishing, lower ISO cleanliness levels will be achieved.
