Quick review of Iwata TRN 1 trigger airbrush

I have set up a pressure gauge on the work top by the side of the paint booth.

 
A MAC valve operates slightly differently though. It reduces air flow without reducing air pressure. You may prefer this.

It's an important distinction, and one that in my experience is not always understood.

I myself am a 'close enough' kind of guy! I set the pressure at the compressor and rarely alter it. It always seems close enough to work :)
 
Never tried a MAC valve, but would assume it makes close range and fine lines easier to achieve without blowing the model away....you should still get the fine atomisation of the higher pressure, but less paint will come out of the end of the brush....is that correct?
 
My compressor is set to 25psi and I leave it at that. I adjust the MAC valve until the AB sprays as I want it to. Varies with what I am spraying - primer, base coat, fine lines, detail work etc. I have no idea of the actual pressure I simply adjust the MAC so that I can do what I need to do. Experience has taught me roughly where the MAC needs to be set in different situations and I go from there. I am most certainly not expert with the AB but equally I don't have any problems.

Jim hi, Do you need a difference connector from the H & S to the compressor. ?
 
Hi John
My set up is very simple. Each of my airbrushes has a quick release whatsit permanently attached. The hose from the compressor has the combined water trap/MAC valve and then the other part of the quick release.

It all joins together and I don't find it awkward or cumbersome. I can change the airbrush or remove it without the compressor losing pressure. I don't have to worry about the air pressure from the compressor. It's a set up that works for me.

Wow that is a big bit on the end of the airbrush Jim.

Matter of iterest does any one get water in the water trap.

Just pushed the valve at the bottom no moisture whatsoever. Been like this for years. Interesting thing. Jersey has an RH (moisture in the air) of 87 average one of the highest in the world. Yet the trap is empty.
 
Yep, I get a fair bit in the one on the compressor. I clear it at the end of every session. Never had any in the secondary PRV though.

Yes clicked. I have a trap on the compreesor as well as the one at work top. Dutifulluy report yes did have half a teaspoon on the compressor one. Not much though. Suspect some moisturizes with the paint which keeps it so minimal as i have not checked it for years. Better have a look at the airfanks me thinks !

Thanks Jim.
The compressor I have now is a Iwata Smart Jet with out the tank.
