Hi Kevin, yes the WackO Products Silencer for Coleman Mach and Airxcel RV Air Conditioners Part # WO34FR will fit your Coleman Mach 3 PowerSaver as long as your unit is a ducted setup, and a really quick way to confirm that is by comparing your ceiling assembly to the examples shown in the photo I attached. If your ceiling vent looks like the ones in the photo, then this silencer is designed to fit right over that setup without any guesswork.
As for the trim ring part # WO74FR you typically won’t need it unless the new silencer doesn’t fully cover the footprint from your existing ceiling grille. If you install it and notice any old screw holes, gaps, or rough edges showing, that’s when the trim ring comes in to clean things up and give it a finished look. Otherwise, most standard installs don’t require it.
This is one of those upgrades that really makes a difference in day-to-day comfort, especially if that AC sits right over where you’re trying to relax or watch TV.
Just to make sure you’re getting the best setup, what area of your RV is that AC located in?
