I know Baldwin very well as my old company used them exclusively worldwide. Interesting thing i learnt from them is they actually make other brands of filters in their own factories under contract. A lot of the fitters used to complain about the Baldwin filter thread vs a Fleetguard or CAT filter as its a pressed thread and not cut, however all of the filters were coming out of the same factory, its just that the external OEM (like Fleetguard) would ask for a different build spec. Regardless of that, the Baldwin brand passes very stringent filtration specifications and should be well regarded.

Also, regarding the first post, full flow filters must be used where the application is in the main oil circuit and bypass filters are for when you connect a bypass oil circuit and filter some of the oil through intense media material. The oil slows right down but gets better filtration. The full flow filter has to be able to pass main oil pressure without creating restriction so the media material is a higher micron rating for better flow and hence lets more dirt pass through.

Search for the Baldwin College Training online. Its very good at explaining this.
