Spraying

[Mike.C]

Draper recommend that you have one of these Air Filter/ regulator/Lubricators inline between the tool and compressor for obvious reasons,

but they also say that if you want to use a spray gun you need to use a Filter separator as a lubricator will cause contamination of the material being sprayed.

So my question is do people normally use two separate lines, one connected to the Air fil/Reg/Lub and one to the Filter Separator and use each line accordingly, or one line and just make sure that the line is free of oil before you start using the spray gun?
My only worry about the second option would be how certain can you be that you have got all of the oil out of the line, by just pulling the trigger a number of times before you start

Or would the best option be just to oil the tools manually by pouring some in the inlet before you start?

EDIT I have just found this which would be fine for all except oiling the toold when not using a spray gun.

I'm no expert on this but if you're using water based finishes does it matter if there's some water in the airline? There's unlikely to be much if you drain your machine reguarly.
I don't have any sort of filter and seem to get decent results. On nail guns I add, when I remember, a drop of air to the inlet of the tool.

Sorry Gidon maybe I did not explain it properly, I mean getting oil in the line when I am spraying

With all the spraying that I've done (car restoration, cellulose or acrylic paints) I never used an inline oiler, only a water trap.


Oh and I drained the air receiver thoroughly before starting each job.

That's what I've always done.

Oil/water in sprayer air lines is not very helpful, and causes craters in the finish. As well as the general purpose filter under the regulator, fit a disposable swirl filter (Axminster) close to the gun.

Mike,
two seperate outlets for starters, one for tools with a oil lubricator attached , but saying that the amount of oil used is minimal, just just the tool a quick squirt before attaching the airline
and the other for spraying,,, you can always use a "TEE" to split the outlet if you only have one.

I have an inline oiler with quick release fittings on either end, can then connect the tool to the oiler or just take it off for spraying :wink: only cost a couple of quid, think it was from machine mart, or may have been ebay sorry I can't be more specific
