you are correct on the desiccant piping,

that check valve is just another lowes ball valve. Currently that shut off lets me use the system, prior to having the "dry air" side complete. Once it is ready it will allow me to service the filters, dryers, when set up to paint, without releasing pressure on the complete system.

on that empty board I will hang: a regulator,and a good dryer and from there will pipe to the two desiccant dryers, these are plumbed in parallel, out of those I will pipe to a filter then on to the paint gun.

I really appreciate the help, and my design has changed quite a bit, but I think for the better. More piping another drop and hopefully this will give me a clean air system...well at least much cleaner than just hose outta the compressor.

Alright, I decided to move the lines to the back wall which is in a stand up space under the house. I would move the compressor there, but that would involve moving the electric and pouring a pad for the compressor to sit on, more money... From the changes made, I'm investing enough and have to say stop at some time. In the 3rd drawing which is sort of a 3d close up of the dryer/filter system, I have a line that bypasses the desiccant filters so that I can route air through it or chose not to use it. There isn't a drop in that line, it would just run in front of the dryers, parallel to the line that feeds into them and then go up into an elbow and then T into the line feeding out of the desiccant filters. this allows me to use the one hose reel mounted to the ceiling for air tools and paint. Thoughts on that functionality and how I have it diagrammed? Not in the design, but it will be added is a check valve on the line routing around the desiccant filters, as one will have to be open and the other closed.

looks good,
be sure to get a drop with a drain where the air makes its first verticle climb just out of the compressor, and tilt the pipes on the wall to run the condensation to the drains.

how much painting do you plan on doing?

[DadTruck]

some smaller projects,, MC tanks, bicycle frames,, and the like,
If I was doing a car, would need a booth

[matts37chev]

i have heard of many guys just using this type of disposable dryers when they paint, with much success.

and this would allow you to make your system a little more low tech (low $$$)

[DadTruck]

I used one of those hose end dryers before, watched it go from blue to pink in the matter of seconds.
Believe what they say in the ad
Designed to complement, but not replace, conventional oil and moisture separators
I nickel and dime some projects. just not every one,, amortize the cost over 25+ years of use,, peanuts.

i did not intend for it to be an end all to air purification
however you did make a couple of $$ comments.
i was just thinking you could use some of those, with a regular water separator and properly plumbed system, if you didnt do a lot of painting.
i have a bigger water separator at the compressor and a smaller one at my reel and get almost no moister.

I have a drop at the compressor, the lines will be tilted towards drains, other than that, will the diagram I have work successfully and properly. I'm mostly concerned around the filter/ desiccant area as that is a lot of plumbing going on and also it just goes to one hose reel. Utilizing that reel for air tools and for painting. I would likely use a disposable filter at the paint gun off the hose reel since it would used for dual purposes (paint and air tools).

My painting would be pedal cars, gumball machines, gas pumps and every few years a rat rod or little car project, in saying that I have yet to get past primer on any of those projects as they tend to be sold at various stages...never completed.

air tools and sandblasting would be the main purposes and I had considered investing in an eastwood soda blaster, but still reading mixed reviews on that one.

[matts37chev]

i would set it up so you can bypass the dryers when not painting
(sorry, if you already said that)
are the dryers in parallel for volume?
if not, i would put them in series (i think this would filter better)
you may just have to change the first dryer more often.

edit:
ok i see you can bypass them

[vintagecar]

so you think in series would be better? That is a simple change...makes sense to get the air running though the first and then the second. What sort of pressure drop would I see with this system?

Anyone use the Kobalt filter sold at Lowes? any good, better than HF?

i dont know what kind of drop you would see
it will change a little as the filters get used, i would think
but a pressure drop is ok, because you will have to regulate down to paint anyway

I think it is time to start buying stuff... oh boy!

final drawing...looking okay?
