Perhaps this is a naive question, but do I need to run a coalescing or water filter on my ARB Twin powered OBA system? I'm currently running my ARB Twin into a Viair 2.5 gallon tank mounted in place of the old spare tire. The tank is inverted, so there's a screw drain mounted at the tanks lowest point. I purge the tank every couple of months which generally results a very small amount of moisture being released. Since I mainly use the system to air up my tires or manage dust, and the compressor is electric, do I need a filter. I get that moisture is a byproduct of compressed air, but seems like that's managed at teh tank drain. And I'm not running air tools nor do I plan to. So, is there any reason to have one? If I have this wrong, please let me know.
