On our 2188 the air in the rad compartment is as dusty as where the cab filter. I am going to take the filter housing and mount it horizontially right above where it is on that ledge in front of the grain tank. The hose should be long enough and it is not normally very dusty there. With a speciality rotor, chopper and spreaders we create a lot of dust. We seem to take out over a pound of dust from that filter daily, very annoying. Rod
