LE LEMATEC Air Compressor Regulator & Flow Control Valve with Pressure Gauge - for Pneumatic Tools, Spray Painting, Tire Inflation, 1/4 NPT, 0-150 PSI

Accurate pressure control and solid metal construction. Keeps my spray work consistent.

Works really well for my set up! No leaks, easy to install and use!

Great product and quality made.

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.

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.

gauges worked perfectly would buy again

This is not an air pressure regulator, it is an air pressure flow control, just a needle valve with a air pressure gauge

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.
