Duracoat - Air compressor setup

[Yerman]

I just bought a nice Passche airbrush so I can Duracoat a couple guns. I have a 6 gal Porter Cable air compressor I use for finish nailers and a couple other tools and have a question about my setup.

I live in Austin TX where it gets pretty humid compared to CA so I'd like to add a filter to get any water/oil out of the air feed. For convenience, I'd like permanently attach the filter to one of the outlets of my compressor so it's always there when I need it.

Is it ok to use a 25 foot hose after the filter or is there too much of a chance of condensation building up inside the hose thus defeating the purpose of using a filter? Another option is to use an inline filter at the end of the 25' hose then use the short 5' hose to connect to the airbrush.

To recap, it would look like this...

Compressor > regulator and filter w/ quick disconnect on the output side > 25' hose > airbrush and airbrush hose with quick disconnect

Or would it be better to do this...

Compressor > regulator > 25' hose > inline filter > airbrush and hose with quck disconnect

Thanks.

Nobody in Kali has ever experienced the foul climate you have in Austin; just try different combinations until you find something that works. Don't do the testing on something valuable...

I'd also suggest some type of air dryer. Refrigerated dryer or at the very least an inline desiccant dryer.

If you don't want to buy a proper air dryer, get a small refrigerator and drill a couple holes in it.
Put a good 25ft coil of 3/8" copper tubing inside the fridge with the ends poking out through the side.
Run your air through the chilled coils and then put the water trap and the filter after the chiller.
Keep your air hose as short as possible after the water trap.

that would be a home brewed cycling refrigerated air dryer

And it's the only real way to get the air dry as possible. the little water trap filters are only there to catch residual moisture
