Digital Air Pressure Regulator with Locking Valve for Air Slip Prevention, 1/4 NPT Inline Airflow Regulator Up to 160 PSI for Air Compressor, HVLP Spray Paint Gun & Pneumatic Tools (DAR03B)

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.

Works great ! I used it for my HTE black widow form harbor freight ! Buying a few more my my other guns!

Love the digital read out and works great. I’m an automotive refinisher so I put it to work. Works great but the only downfall is it’s hard to clean the over spray off at times. With that being said I would still recommend this to be purchased. Affordable and really does a great job.

I decided on a digital guage on my LPH400 because the analog guages are hard to read a lower pressures. My Iwata likes 8-14psi for metallics. The guage is really easy to use. I didn't have to change any of the settings. It reads in psi as is but you can change it if you want. Just turn it on, set it, and spray. The guage turns off after a few seconds. It maintains the pressure well @ +/- .5psi. Good enough for the girls I date👍

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.

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.

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!

So far so good. It works as it should. I’ve painted about 3 cars with it and it’s still working well.

Once you try to adjust pressure up they stop working. I have bought 2 of them and they both did this first use.

A bit heavier than I’m used to but appears to be accurate
