The product wasn’t what i was expecting…
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…

Frequently Asked Questions

Q: Can I use the DAR01B for precise spray gun pressure?

A: Yes, the DAR01B excels at spray gun pressure control. The digital LCD shows exact PSI values rather than approximate analog readings, letting you set precisely the 28 PSI or 42 PSI your spray gun specifies. This precision reduces overspray and material waste.

Q: Is the DAR01B compatible with all air tools?

A: Yes, the DAR01B features standard 1/4-inch NPT connections that fit virtually all pneumatic tools, spray guns, and air accessories. It installs inline between your air hose and tool for at-the-point pressure regulation.

Q: Why use a regulator at the tool instead of at the compressor?

A: Point-of-use regulation gives you exact pressure at the tool, compensating for pressure drops across long hose runs. It also lets you run different tools at different pressures from the same compressor line without adjusting the main regulator each time.

Why Professionals Choose This Tool

  • Multi-Unit LCD Display: Switch between PSI, BAR, kPa, and kg/cm² — works with tool specifications from any country
  • 160 PSI Range: Highest pressure rating in the digital regulator lineup — handles industrial compressor output
  • Backlit Display: Readable in dimly lit shops, spray booths, and under-vehicle work areas
  • Precision Adjustment: Fine-turn knob for 0.5 PSI increments — critical for spray gun setup and calibration

What's in the Box

  • DAR01B digital air regulator
  • LCD display with backlight
  • Adjustment knob
  • 1/4" NPT fittings
  • Battery (pre-installed)
  • User manual

Compatible With

Air Compressors Any compressor up to 160 PSI
Display Units PSI, BAR, kPa, kg/cm² — user selectable
Air Tools All pneumatic tools requiring precise pressure control

Ideal Applications: precision digital regulation, spray gun calibration, multi-unit pressure control, professional air tool setup

What is the difference between the DAR01B and DAR02B?

Both are digital regulators with multi-unit LCD displays. The DAR01B has a 160 PSI range — the highest in the lineup. The DAR02B also rates at 160 PSI but features a different form factor with diaphragm control. Choose based on your mounting and space requirements.

Is digital more accurate than analog for air regulation?

Yes. Digital regulators provide ±1 PSI accuracy and are easier to read precisely. For spray painting where 2-3 PSI difference affects atomization quality, digital readout eliminates guesswork. For general shop use, analog works fine.

Better than advertised

It’s way smaller than it looks which is great for having inline directly under your spray gun. No weight gain and won’t throw off your passes

Easy to use and fairly accurate

Easy to use read and install, not a walcom digital regulator but it is fairly accurate and gets you close for the price range(diy use), got 2 of them one for my off brand mini hvlp and a master pro 22 touch up spray gun, no more guessing what psi/bar i am currently running

Great tool everyone with air compressor should have

Awsome product, once you have one you wonder why you never had one. Yea the air compressor has a regulator but having this is way more precise, better when your painting and applications using precise airflow

The product wasn’t what i was expecting…

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!!!

Easy to install and use

The gauge is super easy to read, so no more squinting at tiny dials trying to guess the pressure. Adjusting the regulator is smooth and precise, and it holds the pressure steady like a champ. I've used it for everything from inflating tires to running air tools, and it hasn't let me down.

My father really likes this and he told me to buy another one because it is really useful for him

This was exactly what my father needed, and he was thrilled that I got it for him. He mentioned it’s the best of its kind, built to last and far more durable than others on the market. It provides accurate readings and performs its job exceptionally well.

Performs great/hard to clean

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.

The Lematec Digital Air Regulator - offers peace of mind and is well worth the $35 bucks we spent.

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

It operated well as soon as I fitted it on my air compressor. There is enough airflow for this regulator to operate correctly. It retains the pressure that is set quite well and is simple to change. Without a doubt, I would suggest this product.

Great tool for precision!

This air compressor regulator with a digital pressure gauge is a great tool for precise control. The LED display makes it super easy to adjust pressure accurately, whether I'm using it for spray painting or tire inflation. It handles up to 160 PSI and works perfectly with my air tools. Highly recommend for anyone needing precision!
