1/4" Air Regulator With Digital Air Gauge

The LEMATEC DAR01A is a patented digital air regulator engineered in Taiwan to manage pressure in compressed air systems and protect downstream air tools. Its aluminum body weighs just 0.2 kg, and it adjusts pressure in increments of 0.5 PSI, 0.05 Bar, 0.05 kg/cm2, or 5 Kpa. It has standard 1/4" air inlets and outlets, an impact-resistant casing, and an auto-shut off function powered by two CR2032 batteries, built for global wholesale, OEM, and private-label partners.

  1. Three pressure units support
  2. Auto-off function
  3. Impact-resistant case
  4. 1/4" inlet and outlet
  5. Protect air tools
  6. Solvent resistant based on normal usage
  7. Provides Accurate Measurement of air Pressure to spray guns or other air tools

The DAR01A digital air regulator is well-suited for precise air-pressure control in automotive refinishing, metalworking, and industrial maintenance settings. It works well ahead of spray paint guns and other air tools, where steady pressure prevents overspray and uneven results. Its 0-160 PSI, 0-11.0 Bar, 0-11 kgf/cm2, and 0-1,100 Kpa range covers most shop air-tool pressure needs, protecting the equipment downstream.

What battery does the DAR01A use, and does it save power automatically?

The DAR01A runs on two replaceable CR2032 batteries and has an auto-shut off function that powers down the display after a period of inactivity, so it does not drain the batteries when not in use.

How durable is the DAR01A for busy workshops?

The DAR01A has an aluminum body and an impact-resistant case. At 0.2 kg, it is light enough for point-of-use placement while holding up to accidental bumps and drops on the shop floor.
