Regulators

Air Compressor Regulators, Filter Combos & Spray Gun Controls

Take precise control of your air pressure with Le Lematec's professional regulator lineup. Whether you need an analog gauge for high-flow spray gun applications, a digital LCD display for exact PSI settings, or a complete filter-regulator combo that cleans and controls air in one unit — we have the right regulator for your compressor setup. All regulators feature standard 1/4" NPT connections for universal compatibility.

Choosing the Right Air Regulator

The best regulator depends on your application. For HVLP spray painting, choose a high-flow model like the AR-01 (89 SCFM) to prevent air starvation. For general pneumatic tools, any regulator in the 0-150 PSI range works well. If you need moisture removal too, our 2-in-1 filter-regulator combos (AI303-R1 or AI303-R2) eliminate the need for separate inline filters.

Digital vs Analog Regulators

Analog regulators offer reliable, battery-free operation with proven mechanical gauges — ideal for dusty or wet environments. Digital regulators provide exact PSI readouts with multi-unit display (PSI, BAR, kPa) for precision applications like automotive painting where even 2-3 PSI makes a difference in finish quality.

Frequently Asked Questions

Q: Do I need a regulator at the compressor and at the tool?

A: Ideally, yes. Set your tank regulator to your maximum working pressure (typically 90-120 PSI), then use point-of-use regulators at each tool to dial in exact pressure. This compensates for pressure drops across long hose runs and lets you run different tools at different pressures simultaneously.

Q: What size regulator do I need for my compressor?

A: Match the regulator's NPT port size to your air line. Most home and small shop compressors use 1/4" NPT. Larger industrial systems may need 3/8" or 1/2" NPT. Our AI303-R1 offers 1/2" NPT for high-flow main-line applications.

Q: Can I use an air regulator with a spray gun?

A: Absolutely — it is strongly recommended. HVLP spray guns require precise pressure (typically 25-50 PSI at the gun) for proper atomization. A point-of-use regulator mounted directly before the gun gives you exact control, reducing overspray and material waste.
