Been looking at some other posts in the search and alot no longer have pictures so fiqured i would ask here for some advise . My 80 gallon compressor is finally in and running. Did not have many options on where to put it so the piping will be further away then i wanted but i can't change it .
I need to do the piping / regulators and filters . Here is a rough drawing of the space and where i want to try to put stuff .
I will be using the compressor for basic air tools and want to do a little auto body work and hvlp spraying . I planned on coming off the compressor ( 3/4 inch - 175 psi ) to shut off valve - then to the 3/4 whip . i had planned on a 3/4 regulator or a water filter/regulator here to lower pressure to 150 psi .
I plan on doing a 3/4 copper line system behind the compressor ( about 35 foot of copper ) then goto the 3/4 inch Maxline ( about 30 foot before the drops ) one drop will connect to the hose reel and the other i wanted to seperate for the hvlp stuff . There i planned on maybe using a QC3 or the eastwood cfs filter .
Where else do i need regulators and filters ( and which type )
The first filter/regulator right after the compressor seems unnecessary. There's no need to drop the line pressure there and without giving the air a chance to cool (by running it through the copper) the water separator won't do much good.
I would wait and put a water separator/particulate filter and then regulator right before the split between the hose reel and hplv drop so you get good clean, dry air to your hose as well and then if you want you can put a final desiccant filter or motor guard filter on the leg for the hvlp so you don't have to change it as often since you're not passing all the air through it for general tool use. Shut off valves could be convenient in several locations but you can always just shut it off at the compressor if you want to work on something downstream, but you'll have so much air in that length of 3/4 line that it will take a while to drain it every time you want to take something apart.
Also remember to slope your line so the water drains back to some point where you can drain it and add a ball valve so you can drain the collected moisture. Finally, remember to tee off the top of the main run and do a little loop down to your drops.
I have the eastwood 1/2" inlet/outlet water/particulate/coellessing/dessicant filter and it's pretty cool, plus it's cheaper that the closest comparable thing by about half.
You don't need copper. Especially with that much line in the system. If you're using aluminum or steel pipe, remember that the pipe from to your compressor to your drops all helps condense out moisture so you get to count that toward your condensate pipe length. Some guys add manifolds because they don't have enough distance/length between compressor and filters. You have 30ish feet which is what most people shoot for. You can always add more. You also probably don't need 3/4 inch line. 1/2 should be more than sufficient. That will help keep costs down.
The hard line/manifold will help cool the air which will will help condense the moisture out of the vapor state but you still need a water trap. And for painting, you will want a fine particulate/coellessing filter. I think mine is .01 micron.
I almost bought that same filter unit. Seems to have good reviews.

Thank you. The 3/4 line kit was a Christmas gift my wife bought me when i had mentioned wanting to get a new compressor so thats why the 3/4 line . I wasn't sure if the total length was enough , ive read different things but most mention 40 to 50 foot ( before actual air hose )
Product Overview
The Manzelli Inline Filter/Water Separator is an upgrade accessory designed to enhance the protection of pneumatic equipment by shielding it from debris and excess moisture commonly found in compressed air systems. This unit features a replaceable inline debris filter cartridge that effectively captures particles of debris 5 microns or larger. Additionally, a water separator efficiently removes excess water, directing it into a collection basin equipped with a level indicator and a manual drain valve. Installation of the Manzelli Filter/Dryer is quick and straightforward. The unit comes with a frame bracket for easy bolt-on installation, as well as an air hose with quick connect for seamless plug and play operation.
