2nd air drier

January 10, 2020, 10:16:38 am

Thinking out loud,wondering if it would be feasible to install a AD-9 or similar drier to the aux air compressor,I know it's big but
this would cure the problem with the old style drying agent not lasting very long,whadda ya think?

Except for the slide bladder coaches, it shouldn't be necessary if leaks are kept to a minimum on the leveling system. I have never heard my compressor come on after I level. I tested it to make sure it worked by putting the coach out of level manually with the air tanks emptied and it came on. If the compressor is cycling all the time a bigger dryer could help.

 Wilkerson manual desiccant dryer I wrote a post a few months back ago about adding an additional desiccant dryer which is much larger than the original I use 100% silica cat litter with excellent results so far you can find them used or even brand new on eBay wasn't sure how to re-post my original post thank you

Just an observation here, based on human nature.
If an owner neglects or forgets to check his/her original air drier, then that same individual will most likely forget/neglect to check the added air drier.
Just human nature.

Johns compressor would be much smaller as is mine. Pre slide ones are small and if all the check valves work only run the leveling system.
