Is there an air filter water deflector available for my coach? It is a side intake rear radiator 3208T Cat. Thanks to all in advance!!!

Donaldson Precleaner removes 80% of water in inlet air system
They make them for vertical and horizontal installations.

Thanks, Scott. Really appreciate it....
Some years ago I posted a picture/article about a filter assembly that I built for my 91 GV 3208T with side radiator and air intake like yours. I still have the same filter element that I replaced new at that time and it is doing well. The filter that I built and installed does a great job of filtering out water and debris. If you can't find it, let me know and I can send you a picture or two. Have a great day ---- Fritz

All I could find, don't need, just curious to see what you did.

The stock air box seems to do a good job . The intake is high, up to the top of the grate and the filter can has a swirlly thing and water duck bill on the bottom . I have never had issues.
I have never had an issue, but my side radiator tends to blow hot air into the engine and filter compartment. Your Rear radiator may be sucking air and heavily laden mists into your air filter compartment due to the velocities created by your huge cooling fan. If you prevent the radiator fan from drawing air into the filter compartment the velocities that carry heavy mists will disappear. At one time it appears my air filter compartment may have been closed off from the engine compartment by a sheet metal shroud, which I plan to add one back.
With the filter located low behind the duals, it gets a lot of road wash and plugs up easily. I doubt that the cooling fan affects that much since it is not running much, if any, when driving in the rain. The thermostats keep it cool by themselves. I like the added filtration and it is so much easier to remove and clean, not to mention how much cheaper it is. Have a great day ---- Fritz
We have a nylon fan on the engine side of our rear radiator and two large fans on the bumper side. Our air filter intake duct is right up against the louvered door on the driver's side.
Yet we have had zero problems with water in the filter.
Is it possibly because we try not to drive in the rain? Or is the water problem typical of all side air intake GVs?
I do have "mudflaps" behind the duals and now a short width rear flap that is only the width of the frame rails and up about 8"-10" off the road.
I put it on just to cover up all the "stuff" hanging down under the coach, like the large caster wheels mounted on the bottom of the frame rails.
I think in retrospect that on our coach, with the big intake shroud up high and being very close to the louvered door, water would have a very hard time getting in. Also, the way the filter is designed and with the water drain in the bottom of the filter housing, any water getting in would drain out. The Donaldson filter and housing design makes it mostly bullet proof. I plan on watching it closely and changing it according to the service recommendations in my Service Manual. If it gets dirty sooner, then it will get swapped out sooner. Thanks again for all the great input!
