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 found this by Bendix;;
air dryer cartridge should be replaced every year or 100,000 miles.
For pick up and delivery operations, or for double- and triple-trailer line haul trucks, every two years or 200,000 miles is recommended.
Line haul operations using a single trailer should swap the filter out every three years or 300,000 miles.
so the more use,less you have to change it...motorhome use looks as if it should be changed yearly...I do 17k a year and change every other year
