This happens to us when the pistons in the little black boxes get wet.
If you take apart the little black boxes, which are behind the blue piece
of metal, and dry and lubricate the pistons, it should take care of the
problem. Make sure to note the orientation of the pistons. I am not sure
why the best lubricant is.
I helps.

Subject: AMMRL: problems with Balston air drier
Our Balston 75-20 air drier has been trouble-free since it was first
installed in 1996, but has recently started to exhibit ominous
behaviors... funny air noises when the columns switch and significant
pressure drop on the output during the cycle (85psi --> 60 psi).
Has anyone had (successful) experience in repairing these units?
Recommended replacements?
Thanks,
--Mike
