Abstract
A system for filtering hydraulic fluid wherein a high flow rate of uncontaminated fluid is required. A housing having a paper filter element disposed therein is placed in a main oil flow line. The housing has a removable cover to which is fixed a rigid cylindrical baffle means which immediately confronts oil entering the inlet to the housing. With this arrangement cold, viscous oil entering the housing through the inlet thereof, which would normally tend to crush the paper filter element, impinges instead upon the cylindrical baffle means where its momentum is dissapated so that damage to the paper filter element is avoided.
