Is it safe to leave an air compressor full of compressed air or should I empty the cylinder when I have finished with it?
I suppose it depends on what compressor you have & if it gets any serious use but you should never run air tools without an in-line filter/regulator; they are not expensive but your air tools will have a very short life if you don’t have one; & don’t even think about paint spraying without one.Whilst water is an issue, it's more of an issue to the air tools being used than the inside of the receiver. Even if you do drain the receiver daily/weekly etc. the inside of the receiver will still be damp.
10cc was a band & a very good one at that; I assume you mean 10cl . You should drain the tank AFTER you use it not before; if you leave the water in there it probably accounts for why you’ve seen so little when you drain it, it’s already converted to ferric oxide inside your tank! Either that or you have a very small compressor.I drain mine before I use it, and, in the fifteen years that I've had it, I'll bet the total amount I've drained from it will be about 10cc of water.
How does that drain the water residue from the bottom of the pressure vesselUnless you have perfect pipes/fittings/valves, it will probably empty itself over a few days anyway.
Prolong the life of the pressure gaugeYou should probably drain it down to prlong the life of the pressure gauge.
How many do you know then have you ever owned/worked in a professional machine/work shop.I dont know anyone that bothers
That’s what I already advised; you said no one bothersOpen the drain tap on the receiver and drains at lowest points on pipework.
Well that’s obvious but it’s the build up of water in the receiver that will cause most problems, not leaving the receiver full of air under pressure which, as weve both said, will drain away.I didnt mean draing the water, i was talking about the pressureised air.
I agree & is what I originally recommended.Applies to a regulator setup, having the regulator under contant pressure will reduce its accuracy over a long period of time. Draining down pressurised systems when not in use is what is supposed to be done.
We seem to have got a little crossed up here but now you’ve made your post clearer, it does make more sense.And yes, most working days for some years now as it happens. Again, i'm talking about air NOT water.
