air filtering best practice

[Bellaireroad]

which comes first in line out of the compressor, oil coalescer or water/particle filter, or does it make a difference? They will be mounted together.

I'm a little confused. When I think of an oil coalescer it is a device that separates oily water into oil and water. In a larger system condensate from the compressor, particulate filter, and dryer all go to the oil/water separator (coalescer). Water goes down the drain and oil is disposed of separately.

What exactly is your oil coalescer?

Looks like in your post you are saying it goes through the water and particle filter first?

Coalescing filter first, particulate second.

I don't think so. You want to get the bigger particles and water first. Coalescing is a finer filter typically. If often only used for sandblasting and painting. If you put it first you're going to burn through your coalescing media prett damn fast.

What are you using the air for? Are you running hardlines? I have a big water filter I use for automotive painting only. I have a smaller water filter I use for other tools. I have never used an "oil coalescing" filter for anything, no reason for it as far as I have experienced. I have never had an issue with fisheyes in any paint I have sprayed.
I think you are over-thinking it...

OK. That is a 0.01 micron filter that they call a coalescer. That is an ultra fine filter. It would be after your water/particle filter. You put your regular filter first, then the ultra fine filter second. That way big stuff gets caught in the water/particle filter and fine oil mists get caught in the oil coalescer. If it was the other way around your oil coalescer/ultra fine filter gets plugged and the water/particle filter never has any work to do.

I am sure you have heard the term FRL. That stands for Filter, Regulator, Lubricator and that is the order they are meant to be used after the compressor. You want clean and mostly dry air entering the regulator. If you do it the other way around, you will shorten the life of the pressure regulator. A lubricator is only used if the line will only be used for tools that need oiled. A coalescing filter is used when you need dry air to paint and would be placed as close to the gun as possible
