Does the screen stay in the system with the Airwolf Filter System installed?
No, the screen is history. All the filtration is accomplished inside the spin-on oil filter. To leave it in the system would require you to clean it every 25 hours and we don’t want you to have to do that. Having said that, we do leave the screen in on radial engines. The reason we do, is all the major radial engine rebuilders asked us to leave it in as they see countless cases of things being dropped into the oil tanks that shouldn’t be there and the screen is the first line of defense to prevent these foreign objects from getting into the engine oil pump and causing a big problem. We see no reason to inspect the screen other than at an annual inspection. Assuming there is clean oil in the tank clean, and we filter it right after it leaves the engine, you are not going to find anything in the screen anyway.
