We have had an RFS SDP-10 in service for 34 years. (Compressor with desicant)
We run about 2 1/2 lbs pressure. It was set at that when I got here. :) 
I have since read that a couple pounds was sufficient - and the limiting factor is the antenna seals.
We have changed the SPD-10's O rings and seals a couple of times, and replaced the desicant half a dozen times. The thing just keeps working.

Hey Guys:

I'm curious to know how much pressure you put into your transmission line and how you arrived at that number. I want to compare that to what we set ours to.

How many pounds of pressure do you set your line pressure to?

Also, what do you use?  Do you use a nitrogen tank, dehydrator, or some form of air compressor with desiccant at the output.   And why? 

I find it disappointing that Phartronics may be out of business.  As much as Willie loves the name of the company, they made a good product that we have used at most of our transmission sites.

Have a great and quiet Thanksgiving!
