Frequently Asked Questions

Q: How accurate is the digital pressure display?

A: The DAR02B digital LCD displays pressure within ±1% accuracy across its 0-160 PSI range. The multi-unit display shows PSI, BAR, kPa, and kg/cm² simultaneously, eliminating conversion errors when following specifications in different unit systems.

Q: Does the digital regulator need batteries?

A: Yes. The DAR02B runs on a replaceable CR2032 button cell, and one is included with the unit. Battery life is typically 2+ years of normal workshop use. The LCD automatically dims after inactivity to conserve power.

Q: What's the difference between the DAR01B, DAR02B, and DAR03B?

A: All three are digital regulators. The DAR01B is the standard model with push-button digital gauge. The DAR02B features a diaphragm-style regulator for smoother pressure adjustment. The DAR03B is the premium model with the highest flow rate and most precise control. Choose based on your precision and flow needs.

Compatible With

Air Compressors Any compressor up to 160 PSI
Display PSI, BAR, kPa, kg/cm²
Air Tools All pneumatic tools

Ideal Applications: precision regulation, spray painting, digital pressure monitoring, calibration, professional air tool setup

When should I use a digital regulator vs. analog?

Use digital when precision matters: spray painting, airbrush work, calibration, and any application where 1-2 PSI makes a difference in results. Analog is fine for general shop use where approximate pressure is sufficient. The digital display also eliminates parallax reading errors common with analog gauges.

Customer Reviews

Customers praised the digital display for being "easy to read" and accurate, with smooth diaphragm control ideal for painting and sandblasting. However, concerns about accuracy (10+ PSI variance), pressure retention issues, leaks, and auto-shutoff display were noted. Some units arrived defective or stopped working during first use.

  • Love the digital display. So easy to read.
  • Proper Air Pressure Control for My HVLP Sprayer
  • The spray gun pressure stays consistent now

Great improvement over analog

Updated a 20± year old Air compressor. Plumbing, hose, and went to high flow connectors.Yes this gauge doesn't stay on, but who really needs it to stay? Very easy to set not guessing or having to look harder that needed.Very accurate due to have a Digital gauge for the tank itself.Broke the original Pressure switch by accident and had to modify the cover but overall no one would guess its a 20+ year old Air compressor unless they know compressors

Perfect to regulate air pressure for testing

It was perfect for regulating 29 psi for the job I was doing

Now I can just dial in the air pressure

Using a tire gauge on each tire four or five times to get the proper pressure was a pain, if I could find the tire gauge. Using this regulator, it’s as easy as setting the pressure and then letting the regulator do the work.

Does the job - small and compact

Was using this gauge and reg for relatively low flow instrument work. 5to90psi no problems. It’s small and compactthe digital gauge goes to sleep rather quickly otherwise no problem.

Works well however the screen times out in about in 10 seconds.

Proper Air Pressure Control for My HVLP Sprayer

I like the full stable pressure control of the regulator. Most of what's out there is just a simple needle valve, not as regulator. This is reasonably accurate at an extrodinary price. Fit's my HVLP gun and does a great job at keeping pressure.

Crap

Is not precise

Terrible Chinese regulator

This regulator not only does not match the description, it is not able to work at all. Terrible Chinese quality. Never buy Chinese products again, and do not order this device.

Very inaccurate

I wanted to get an other diaphragm regulator for one of my spray guns and this particular regulator reveals to be the worse of all. The pressure shown on the screen is at least 10psi more than what it is in reality.

Learning curve

have to play with air inlet on gun as well to get desired psi. Not bad I like it

Complete JUNK, Do NOT Purchase

Unfortunately I waited too long to use this regulator, over the 30 day return period. It would never adjust properly, kept bleeding off the pressure after setting, followed the instructions and it never would adjust properly. Going back to analog regulator, this thing is garbage.

Fits snug, no leak

The only thing I don't like is that the digital reader shuts off after 10 seconds.

Leaks

Leaks where the display goes into the gauge and it looks like it has some kind of glue holding it in so I cant even take it off to put thread tape on. Also had to buy adapters for my airbrush hose. Display turn on but is hard to read without any kind of backlight.

Works perfectly

When you are given instructions to operate a specific tool at a certain psi, this product should be the answer you need. The digital readout is clear and easy to read. Changing the battery is a snap,( rim shot, pun intended.)

that it works when it arrives

bought 2 units one worked fine. The second unit did not turn on. Suspected a dead battery. Instructions they provide for use does NOT include any info on how to open unit and replace battery. Had to go to Youtube to find out. Bought an new battery ($10.12) and installed it. Unit then worked. Seems their quality control department should add a final test BEFORE the product is shipped. Also for a bit $ more think they should include a male to female adapter on the air pressure input side so you don't have to go by one if you have a male snap in connector from your air hose.

Better than my old regulator. The spray gun pressure stays consistent now
