If you use desiccant how long is it lasting before you need to change or bake it?
I know the answers will vary according to climate, usage, how your system is set up (filters, dryers, pipe etc.) and likely other factors.
My system in order: 5HP compressor, 80 gal. tank with an auto drain, Apx. 38' of 1/2" copper pipe pitched down to a bulk water trap, then 2 side by side 5 micron filters, another 23' 1/2" copper pipe pitched down to another 5 micron filter with a .01 micron coalescing filter next to it . Then a 10lb canister of desiccant (from a old CAM-Air set up). Then out to a regulator, 38' of 3/8" hose fitted with Hi-Flo fittings. I drain the bulk water trap often and get very little water out of it and the first 5 micron filter right after that. I get nothing out of the 2 filters just before the desiccant canister. Installed all this in February after some problems, system works OK. Just noticing the desiccant is starting to turn purple which I guess means I will have to regenerate it soon. July has been extremely humid but I haven't been painting all that often lately. So 5-6 months here, so far with intermittent use, for the desiccant.
