Goose, I did look it up. I can't find squat about PM of the air drier / desiccant renewal in the shop manual. There are schematics and instructions on how to remove and replace the drier from the air supply unit (it's built into it of course, along with compressor, valves, etc.), but no mention anywhere of how often it should be serviced. My guess is: not until it's broke. :wink:

Thanks again Umberto for the excellent info the whole system!!

I'm guessing the dessicant volume is sized so that even as regeneration efficiency declines over time, it probably lasts as long as the compressor is designed to. Even these regenerative dessicants are changed out every few years on the commercial systems, but there its more critical that the brakes always work when you press the pedal ;) ...that's why I was curious.

Who knows? All I know is water+compressor=bad, esp in winter. But if LR says not to change it I won't.
