Compressor Drain

Does any one add any drying component to their compressor tank, or does keeping the valve cracked at the base of the tank suffice? Inquiring minds want to know! CM
 
There is always going to be a certain amount of water in a compressor tank no matter what you do. If you add anything into the tank it's going to make mud which will just hold the moisture to the metal and make it rust out faster. Your best bet would be to set the compressor to where it drains toward the drain cock and open the drain just enough that a tiny amount of air leaks all the time. When enough water condenses in the tank to make it to the drain cock it will come out.
 
The idea of a drying component will retain moisture, theoretically within the drying component. This is still moisture within the tank, which is the vary thing your trying to avoid.
I was overdue on draining a compressor tank one time and it had a LOT of use on it. The amount of water that came out I think could of been measured in gallons. There would of been no way a paper towel, floor dry, or sponge would of absorbed that much water. Not even with the Bounty Quicker Picker Upper. Adding a drying component to tank and forgetting about it, would be a bad idea.
 
I added a piece of 3/4pipe to the drain hole, it gets the water out of the tank till I drain it

I have a 80 Gal. tank from Eaton Compressor that I want to make a moderately complex moisture trap for. I would merely install a AC condenser coil onto a defunct 5 Gal. Horizontal air tank. Pri. Comp. air goes into condenser getting trapped in 5 Gal. tnk and air is rerouted from top or end of 5 Gal. tank back to 80 Gal. tank. It should be moisture free I hope. My setup is in a uninsulated pole barn.
 
i simply plumbed another air line into the drain port and use it for blowing the floor clean and for just letting moisture out. have line on both tank bottoms have two eighty gallon tanks t together for air storage.
 
I bought a electric water drain and it automatic lets a shot out i think every 20 min i think when i dont use the compresser i just shut it off works great i think it was about $25
 
Buy a GOOD automatic compressor drain, make sure your regulator has a moisture drain and also any long runs should have a drop pipe with a drain valve.

Do not scrimp on the auto drain, the cheap Chinese ones are junk and you will be constantly cleaning them. This is the best, I've been running this one for several years. Put a ball valve before it so you can service it without draining the tank.

I have it wired into the low pressure kick on, so every time the compressor kicks on, the auto drain runs for 3 or 4 seconds.

If you will be doing a lot of very moisture sensitive activities, a Harbor Freight air dryer may be needed. Your Shop/garage just cannot drop below freezing.

It appears that some responders have seen the word "component" and have taken Chuck to be saying "compound" I thought that chuck meant some sort of automatic tank drain, like so many other guys here have suggested.
