Compressor piping question

[flyboyjuge]

Ok guys I searched but didnt find a clear answer. I just downgraded to a 30 gallon compressor. the husky vt6315 to be exact and will only be painting small parts. a hood at the largest. motorcycle parts mostly. I live in a rental house. Do i need plumbing to keep water out, or is there something else I can do. for a small 30 gallon, I hate to get all overkill with my piping. I like the compressor because it is mobile. Any advice is appreciated. I have been using just an inline filter right at the gun. no water or oil....yet. thanks guys. and as always Surefinish is the best!!! Julian

your easiest and cheapest way would be to run the air from your 30 gallon tank through 25 to 50 foot of hose or piping into the side of a smaller tank (5 or 10 gallon) then pull your supply off of that tank from the top of it. the hose or piping will cool and condense most of the moisture and let it settle in the smaller tank unless you just flat out draw the smaller tank, with what you are doing i think you would be alright. just keep the smaller tank bled of moisture quite often. if you have more seperators include them anywhere in the system but make sure you have one on your last hose section for sure.

I was at home depot today and it showed diagrams of just 50 foot hose coming out of compressor into a filter then another 50 foot of hose then the tool. would this fight moisture at all? a long way for air to travel but does air hose rid moisture at all?

rubber hose is not going to cool the air very well. Plus with 100 feet of 3/8" air hose I would be worried about a pretty good pressure drop as well. You'd be better off running 25' of black iron pipe (at least 1/2"), put a water seperator at the end, and then not worry about it. That amount of pipe will be super cheap.

I agree with the Black iron pipe but with it being a rental home, i cant really get too in depth with it. if i did a shorter length with a more bends as in up then down then up then down, do you think that would work?

Rubber hose holds the heat and the moisture, you want as SHORT a hose as possible. But you want this hose AFTER the air has cooled, that is the basic idea. Cool the air with piping away from the compressor. Piping that is blocked away from the wall so air can get around it. Then after that air has cooled, you have as short a hose as you need to get the job done. That is it in theory, however you can do it, that is basics.

A set up like this, is the perfect garage piping.


Getting as close as you can to this is the best. But we can't always do it perfectly, so you get close. I have a simple set up like this in my garage with only one outlet at the end, with a water separator there.

If you put them up and down, the water is going to be trapped at the lower end and restrict air.
