Filtering compressor air

Guys/girls...

Some of you know how fussy I am about dust on my models (hi Antonio and hi Mika, wherever you are! :wave: ) I think that I'm getting most of it with the air from the compressor. Could I have some suggestions on how to remedy the situation? Are there any specialised filters for this (I think I want to filter the outgoing air, not in incoming one)? Alternatively, I was thinking of using a cheapish in-line fuel filter for cars, but not sure how it will be able to take the pressure in the hose... Need some help, and TIA

Sandro?

Go to a pneumatics supply store and explain your situation to them, there are inline air filters available.
An fuel filter will likely create more restriction than help....

I have some doubts about the dust coming through the compressor though, it is more likely the compressed air is kicking the dust in the vicinity into the air and it is getting caught in the air stream....I used to have a problem with this myself.

That's exactly what I was thinking, and luckily, I found a pneumatics shop abouta week ago. It's a rather long drive though :(

So what did you do? And I clean my spraybooth before spraying.

I keep my entire work area clean, my previous apartment was a dust trap whereas this one is not.
Do you allow the fans to run a reasonable amount of time before you start spraying?
I usually allow the fans to run at least 15 minutes before spraying, this way any airborne dust is already drawn into the filters before I start spraying so there is less chance of it joining the paint stream onto my model.

No, Olivier just called me that once and I liked it. You know, Alex, Alexander...

And this apartment is a dust trap, unfortunately... And my fans do run a while before I bgin spraying. I'll take a trip to that shop and see if I can get anything useful there :)

Thanks, Ray!

If to bastardize, might as well bastardize the best :cool:

You might be shooting dust from your paint jar. Make sure your jars are clean and you store them shut and/or upside down. Then clean them again before spraying. Look at your dust closely. If it's on the surface and can be sanded off, it's from floating around. If the dust is imbedded in the paint, most likely it came from the jar. Strain your paint before shooting; pantyhose is best/cheapest for this.

I don't know what kind of equipment you have, but dust from teh compressor is unlikely unless you store your hoses disconnected and dust is getting into them. You can get disposable in-line filters that go at the end of the line (or where you have the last NPT fitting). But at the absolute minimum you should still have a filter/moisture trap right at the compressor outlet before the hose.
