Paint spraying advice
Barksavon - 15/4/18 at 07:36 PM

Any paint sprayers out there...?
I'm looking at the best and most reasonably priced method of removing sufficient moisture from my compressed air to enablement me to make a decent job of painting my 1958 Austin A35. There's a one stage filter regulator, costs about £20-50 , a three stage filter regulator which provides breathing quality air , around£300, and a filter sold by Rtech welding called an AT1000 £80ish, which is designed for plasma cutters. All 3 are supposed to be suitable for painting according to the spec sheets
I'm sure the 3 stage system would do the job, does anyone know whether a one stage does a good enough job and has anyone any experience of the AT1000. One more question, could I run a breathing mask and my spraygun from a 3 stage unit, my compressor is a3hp 50 tire tank

Two vertical copper pipes looped together at the top, and a tap on the bottom of each leg of the loop, 300mm or so from the bottom of each leg, insert a tee, compressor feed into one, output to gun, or regulator from the other.

Water vapour will condense in each tube and fall to the bottom, after use, open the taps and drain the water off.

Thanks for the suggestion Pete, is that a set up you have used?

Yes, Its surprising how much water comes out after a couple of hours spraying.

Mine runs almost floot to apex of grage roof, I run it into a cheape seperator regulator, but there is never any moisture in the bowl.

Have you used 15 or 22mm copper tube in your set ups
