Has anyone used the T.R.A.P breather from the Donaldson Corporation? If so do you feel that it worked as well as a desiccant breather for keeping moisture out the system? Has anyone taken before and after oil samples to determine the effectiveness of the T.R.A.P breather? I am thinking of using this breather and I want to be sure that it will keep moisture and particulate out of my hydraulic units and gearboxes.
