Good question! If the PS is located where you are going to get rocks in it, then you should put a screen over the inlet tubes. Rocks could knock out a fan blade like they could on a radiator (rocks flung forward by the rear tire). But most mount in such a way that this is not an issue and sand is no problem, nor is snow.So what happens to the centrifuge fan when the front tire kicks up, or the vehicle in front of you roosts massive quantities of fine to medium sand directly into the intake of the particle separator? Does all this sand then pass through (or need to pass through) the centrifuge fan to fully and completely exit the unit?
