LE LEMATEC Digital Paint Gun Air Regulator with LED Gauge, 1/4 NPT

The Lematec Digital Adjustable Air Regulator is actually smaller than a typical analog regulator, but that’s okay as it’s still easy to read. It does what the company advertises it can do. We now briefly use this digital regulator in conjunction with our high flow locking analog regulator as a quick accuracy check in the morning. We keep the high flow analog regulator permanently attached to our portable pancake compressor. The digital gauge is left wide open and only gets attached momentarily to the business end of the pressure hose (100 foot long) where our nailers will get connected prior using our air tools. To clarify, it’s just an on and then quickly back off again operation. The tool never actually gets attached to the line while the digital gauge is on the end of it. The reason we do this quick pressure check each day is to ensure that the air flow always remains consistent before we get to work using professional grade floor nailers. It makes the job go quicker and easier as the nailers definitely run much smoother when the air pressure is consistent. The Lematec Digital Air Regulator (digital gauge) offers peace of mind and is well worth the $35 bucks we spent.

As many of the reviews stated, this is not a true diaphragm based regulator. It's a simple flow restrictor that in many cases is adequate for the application. My needs were for an accurate digital LVLP regulator so I removed the gauge and installed it on a cheap Harbor Freight mini regulator. Works awesome at the180 second turn off time but the battery just died. Hopefully new battery lasts longer

Easy to use, quality is better than others and laquer thinner dosnt melt the guage like my others. Precise airflow measuring as well.

I’ve had this regulator for several months now and I use it in the shop where I work, so it’s getting used every single day. It works great, it’s got nicely sized numbers so it’s easy to read and the gun cleaning solvent doesn’t seem to affect it. I would say The only complaint that I have is that it shuts off automatically, you can set it for 30 seconds one minute or two minutes. I’m sure that the reason for this is there trying to save the battery but it is a little bit of a hassle to have to keep turning it back on to make sure that the pressure hasn’t fluctuated on you while you’re spraying. Still It’s a great little regulator and it is literally half the price of the Devilbiss.

Perhaps my unit was defective - I had high hopes for this one - but it fails at the most basic function of regulating air pressure. To set the air pressure, I used a blow gun and dialed in the desired pressure e.g. 13.5 psi. Once I released the trigger, the gauge would climb up to hose pressure e.g. 90 psi. Upon initial pull of the trigger again air at 90 psi would come through the blow gun until it bled down to the 13.5 psi, it took anywhere from 2-5 seconds. While this isn't an issue with a blow gun, it IS an issue with an HVLP gun. I used this regulator for the first time and I had to bleed off pressure during each trigger pull. I may have just had a defective unit, as others have not had this problem. Luckily, amazon has allowed me to return the item. Now I just have to search for a replacement that works properly.

Just getting into painting cars and I needed something to regulate air pressure. This thing is awesome! Build super nice, easy to adjust and super easy to install and use. Can’t go wrong for the price!

IT WAS BETTER THAN I EXPECTED!!! Looks sleek, small and doesnt obstruct, pretty durable. The only gripe I have is that it only shows active pressure and doesnt hold the value but thats to be expected as I’m using it outside of its intended purpose. I do tires for a living. Got a chuck attached to this regulator, and then a valve. Once the valve is cut off, it shows the current pressure in the tire. The complaints I’m seeing are from people NOT READING THE INSTRUCTIONS!!! The instructions tell u how to change the time out timer. I show how to do it in my video. It deserves 5 stars. It’s very accurate as i have tested it against a master gauge and it was only 1 psi off. It can be zeroed and i will be zeroing it tomorrow and testing it again against a master gauge. To zero the device, watch the video and click the button when the middle dash turns into a 0 and it will do 00- and then E and turn off. It’s zeroed after that. Frfr, READ THE INSTRUCTIONS!!! UPDATE!! Please read. Let me explain why its going from 5 stars to 3 stars… the aluminum body that houses the regulator.. please for the love of God use stainless steel… the aluminum tip broke off in my handle. It started as a crack that i couldnt find because i could not see the crack. I could tell it was leaking. Eventually it just outright snapped off… I decided to not go with a regulator and just got an oil pressure sensor tee made from stainless steel to put the gauge on. Now that 1/8th to 1/4th is because the other end also broke off. I couldnt tell if it was aluminum but it is definitely fragile as well. I cant give it a 5/5 anymore because the durability is garbage. Now the gauge is still good value so i would recommend getting just the gauge and finding ur own regulator to stick it on. And yes, design changed so i could attach hoses to it to get some distance from tires. Not all the time do I like to stand right next to a 3 piece lock ring while airing it up to 145psi. And yes, it is still as accurate as it was in the original configuration. 1psi difference from a master gauge. It is pretty ironic that my original review said “pretty durable” and then the thing just kept breaking on me 😂 Change the design to a steel regulator and i will change the review score back to a 5/5. I dont think anyone would mind paying more for something more durable and i understand you might have to sacrifice the aesthetic blue regulator but it honestly doesnt look bad in steel. Looks sleek.

I’ve had two of these gauges for two years, and they are amazing! I’m a production painter in Florida and have put hundreds of hours on these gauges, and they are still working like a charm. I have one on a devillbiss Tekna base coat and a devillbiss tekna prolite. I’ve have a few of the devillbiss gauges, and they alway last for a few months then give up. I highly recommend these gauges over the divilbiss ones.
