They are just twin tower desiccant dryers in a stylish package. Nothing exotic about them. Coalescing filter up front with a proper automatic drain on it, run the air through the dryer at specified flow rate and pressure, particulate filter at the outlet. Dryer should switch towers every 5 minutes or so, unless there is an economy mode that measures dewpoint and only switches when necessary. Not much to go wrong unless there's some proprietary electronics onboard, and even then you can sometimes work around that if they are fubared. It might be worth dumping the desiccant to see if it is oil fouled, since that renders it useless.
This is a proper bit of industrial equipment. If you got it cheap and it works, you've done very well for yourself.
EDIT: Ok, looks like it was never used, so even better. Check to see that there is desiccant in the vessels, as it will not work without it. Some dryers get shipped empty with the desiccant in a separate container to help eliminate attrition during shipping and dust creation.
You lose about 10% of your air flow to regeneration purge, so keep that in mind if you are borderline on your compressor sizing.

There should also be some provision for the dryer to know when a reciprocating compressor is off, so the drying process timer doesn't keep running and cycling for no reason. This would be a huge waste of air and drive up your running costs immensely.
Correct, i picked up two brand new dryers, four filters, and a huge grainger box of dessicant from this auction. Thanks for the insight, might have to call spx to get product manuals for these.
I don't run a paint gun, plasma, or anything else. Should i keep them or sell them to someone who could actually use them?

I'd sell them on. Should be an easy sell, even here on GJ. Lot of guys on here looking for clean, dry air for painting.
15CFM is not a huge amount of air, so if you price them right, you should have lots of interest from DIYers, but industrial users are probably looking for a lot more flow. That's about a true 5hp compressor's worth of air.
This would make a good instrumentation air setup for valve actuators and the like, especially if they are outdoors in winter.
Ebay might be a good bet too. I'm betting they are not cheap units.
Heck, if you wanted to flip them quickly, I bet local compressor shops would be quite interested.

Thanks man, I've got them on craigslist, no bites yet.
