Q:

Three Stage Air Drying System – Use w/ ShoeBox?

This item was stumbled on when I was looking for something else. I am not technically savvy enough to asses whether or not it would work well drying the air between the first stage, shop compressor, and the ShoeBox, but it looked promising to me. What do you think?

Before I saw this item, I had already bought the Desiccant Air Dryer (5163K18) from McMaster-Carr recommended by others here. I expect the one I bought will fine, but I am curious about the one linked above.

Compressors, tanks and pumps

While it is nice to remove as much moisture from the feed air, the most efficient way to remove moisture is to compress the air. Air is compressible but water is not so if it is at a fairly high pressure, a moisture separator and chemical drier will be as much as 400% more efficient. So, your best arrangement would be:

Feeder compressor >>> water separator >>> Shoebox >>> moisture separator >>> chemical filter >>> pressure maintaining valve >>> outlet hose

That will work but to get max amount of water out with that system you should.
1 run 25 to 50 ‘ of hose from the compressor to the dryer. This lets the water cool in the hose.
2 then you can run a short hose from that to the shoebox.
You can keep the hose coiled what you want is the compressed air to cool and let the steam turn back to water that makes a big difference in the amount of water removed from the air line. If it is a humid day you can take the hose coil it and put it in a bucket of water that will cool the air even faster. I have been selling airtools for over 20 years and it will work.

Thank you! Is there any reason why your recommendation would not apply equally to the desiccant dryer? I had thought about the length of hose, possibly running through a chilled bath, or some other type of condensing unit. My present plan is to use the big desiccant dryer between the shop compressor and the ShoeBox, the high-pressure Alpha filter between the ShoeBox and tank, and call it good. If I detect any indication of moisture beyond the tank, I will consider a plan B.
