The Baldwin BF1275 (AD says they are switching to this filter) is rated for 99% free water, 96.5% emulsified water sep at 120 GPH. The filter supplied with the AD is 95% free water and 75% emulsified water sep at 90 GPH. OEM is 98% free and 95% emulsified water sep at 60 GPH (higher than the OEM pump pushes).
The FF5613 is 5um absolute and 2um at 94% at 60 GPH, the P551315 is 3um absolute at 90 GPH.
So will the Airdog still function correctly with the more efficient Baldwin and Donaldson filters? ... Air separation and flow rate will be the same?
