LE LEMATEC Air Compressor Regulator Valve with Pressure Gauge, for Precise Control in Air/Pneumatic Tool Applications, Spray Painting, Tire Inflation and More, ¼ NPT, 0-150 PSI (AR-01)

GREAT REGULATOR.MY STATIC LINE PRESSURE IS ABOUT 90 PSI AND THE MOST I CAN GET PAST THIS UNIT IS 40 PSI. UNSURE IF THATS CORRECT OR NOT BUT I PAINT WITH IT SO 30 PSI IS ALL I REALLY NEED.WATCH FOR A SIDE KNOB UNIT LIKE THIS ONE. WHERE THE ADJUSTMENT KNOB STICKS OUT OPPOSITE THE GAGE IS TROUBLESOME. IF YOU DON'T KNOW THIS, BUY THE OTHER KIND AND YOU WILL LEARN THIS

I have 4 of these regulators and they work great. I use them on each of my spray guns. No more trying to compensate for the length of the airline, just set your pressure at the gun and go to work! They hold pressure very well.

Nice valve. Well made. I recommend. Bought it for a compressor.

First I have to say that I'm new to air spraying paint, so I realized very quickly that I needed a flow regulator IN ADDITION TO the line regulator that was already on my (and pretty much every) air compressor. It's possible to rely just on your compressor regulator, but if you use more than one kind of spray gun it's best to monitor your air at the tool. In my limited paint spraying experience, I would agree with the other more knowledgeable reviewers that this device does EXACTLY what it's supposed to do....regulate air flow pressure not static line pressure. The reason for my four stars is that it's a little touchy down at the low end of the scale. I also agree with a few negative reviewers that the title can be misleading, this is not a "compressor regulator." Other than that it seems well made and has a glass lens. I don't understand how some people are using this with tools such as air nailers which rely mainly on static line pressure or using this to swap out their regulator at the compressor which is required for setting the static line pressure for use with other air tools. This regulator is for measuring flow and is mounted on/near a tool that benefits from managing air flow pressure while in operation. It does not manage your static line pressure and, therefore, is not for setting line pressure at the compressor. Keep your normal pressure regulator that came with your compressor. For my purposes (small guns; Auarita MP-102, Central Pneumatic mini) this worked great. I wouldn't hesitate to buy another regulator if I wanted to permanently mount them to the gun for convenience.

gauges worked perfectly would buy again

This valve is awesome! I bought it because I read in the reviews that the lense on the guage is glass and not plastic. The plastic lenses get hazy if you get solvents on them. Big plus that it has a glass lense. I was surprised in the quality of the valve. It's really smooth and accurate when you adjust it. Turn it to the pressure you want and it stays there, no fluctuation. My Devilbiss valve has a glass lense but the adjustment is not great. If you set it and let go of the trigger and depress it again, it doesn't return to your setting. So you have to adjust again to get it right. Not the Lematec. Just set it and forget it. It's made in Taiwan and I've noticed that tools made in Taiwan are usually of better quality than some from China. I like the blue anodizing. Nice tool👍

The airflow is very easy to adjust and the accuracy seems to be on point. I did have a problem midway through paint which was it leaking however just tightening it down more fixed that. I’ve washed this thing 10ish times and drenched it with thinner to clean it and still works great.

Ordered two originally, worked great, then I had a couple more spray guns to put them on but after buying one I found that it was defective in its accuracy and its regulator dial not working properly. I returned it and got a new one, same issue, regulator dial not working and not accurate whatsoever displaying psi well over 50 at a displayed 15-20psi. If you get a good one its great, seems like a specific lot/batch is defective
