Yeah, that is definitely a after factory setup. Nothing wrong with it, it’s just different. It appears the check valve in the system is just after the air dryer/particulate filter.
I actually think the setup is quite clever with the check valve AFTER the drier, because as some of us know the drier bowl cracks and usually is a big leak source. It’s not if the bowl cracks, it’s when. This way a cracked bowl isn’t a huge problem. The owner has to manually drain the bowl, no big deal.
Good catch @"RussWhite" on the a failed check valve also giving the same symptoms.
