I purchased an Air Venturi from PA. Some bright specialists, both sponsors and members, have spoken about the importance of the air going into our PCPs be without moisture. Does the Air Venturi have a filter supplied with it that does an adequate job of removing the moisture? I will add extra filtration if it's needed but obviously don't want to experience the expense and hassle of doing that if it's not necessary. I do shoot a couple of nice rifles. I have a FX T12 Whisper and a FX Royale 500. I would like to keep as good care of them as I can. Thanks.
