Wabco 1200 air dryer cartridge question
Does anyone know for sure(without guessing or just personal opinion) If a Wabco 1200 series air dryer cartridge goes bad based on time but not mileage?? 29000 miles but 10 years old; never if hardly...

Just because you don't operate in damp / humid conditions has nothing to do with the cartridge getting saturated. It has to do with compressed air and the dew point of it.
When you compress air, it raises the dew point (holds more moisture) so the filter pulls that moisture off no matter what the ambient humidity is.
Replace it. It. It's saturated.
thanks for your opinion
Not an opinion at all. Fact. I drove and owned a number of over the road trucks and SOP was dryer cartridge replacement. It's very important to pull out the entrained moisture or it will gum up your works down line.
