Looking at older Paasche D compressor with the air tank which had a pressure switch to turn it on and off and a regulator . Yet it did not have any sort of moisture trap or any sort of drain on the tank. Yes one can easily add a moisture trap and add an in line moisture trap as well .
Here is my question.
Every air compressor creates heat which in turn creates condensation by nature. So why no tank drain on most air brush compressors ? Also when one uses an air tank like one would use to fill with air with a compressor at home or say at a gas station . Mainly they are intended to have a supply of compressed air for filling tires or any other use yet they have no tank drain value either.
My old sears motor /belt driven two piston compressor 12 gallon tank army green unit has a tank drain as well as a built on regulator and pressure shut on/off switch and I added a Paasche regulator/water trap with gauge and it has a pressure gauge on the built on regulator and a gauge that reads the actual tank pressure before regulation . I drain the tank after every use. Now win no tank drain on any air tank whether the Paasche unit I described or a portable air tank seems to me the water will just remain in the tank until it rusts through which could take decades or the water will slowly find it's way out through draining the regulator /water trap . I added on 10 gal air tank to my sears compressor yet instead of the tank sitting with the value on top I hung it upside down didn't use the brass valve and hose it comes with to fill tires , I just added a gauge and a new hose down to a port on my sears compressor with a quick disconnect so any water in the add on tank would drain down the 5 feet into the sears tank then I could drain both tanks and if I didn't need the extra 10 gallon tank just use the quick disconnect on the hose . If I fill the extra tank I do it from the compressor through the hose not the included tire/air valve and insert a regulator /water trap to the tanks quick disconnect fitting pull disconnect the hose , shuts off release of air from tank , later added an air value , then I have a dry tank with a regulator / drainable water trap as the Paasche one is and then I can use the tank/air brush anywhere .
I suppose a drain can be welded or rather a fitting welded to any tank so a water drain valve can be added .
