Why Professionals Choose This Tool
- Spray Gun Precision: Fine-adjustment knob lets you dial in exact PSI for optimal atomization — critical for automotive paint, stain, lacquer, and clearcoat application
- Mounts at the Gun: Installs directly at the spray gun air inlet for point-of-use pressure control — eliminates pressure drop through long hoses
- 0-160 PSI Range: Covers the full range from delicate airbrush work (10-15 PSI) to high-pressure conventional spraying (50-60 PSI)
- Universal 1/4" NPT: Standard threading connects to any spray gun, air tool, hose fitting, or compressor outlet
- Clear Analog Gauge: Easy-to-read dial shows exact delivery pressure — no squinting at tiny numbers in a spray booth

Frequently Asked Questions
Does the AR-08 fit all spray guns?
The AR-08 fits any spray gun with a standard 1/4" NPT air inlet, which is the industry standard for HVLP and conventional spray guns. It mounts directly to the gun handle for at-the-tool pressure control.
Why do I need a regulator at the spray gun?
Wall-mounted regulators lose accuracy over long hose runs. An at-gun regulator like the AR-08 gives you exact PSI at the tool, ensuring consistent atomization and finish quality.
Why do I need a regulator at the spray gun instead of at the compressor?
Pressure drops 5-15 PSI between the compressor regulator and the spray gun due to hose length, fittings, and friction loss. The AR-08 mounts directly at the gun so you see and control the ACTUAL pressure entering the gun — not the pressure leaving the compressor. This is the difference between amateur and professional paint results.
What PSI should I set for HVLP spray painting?
HVLP guns typically operate at 25-35 PSI at the gun inlet (not compressor outlet). Start at 28 PSI for basecoat and adjust based on your specific gun, paint viscosity, and fan pattern. Clearcoat usually needs 2-3 PSI more than basecoat. The AR-08 fine-adjustment knob makes these small changes easy and precise.
Can I use the AR-08 with a sandblaster or other air tools?
Yes. While designed for spray gun precision, the AR-08 works with any 1/4" NPT air tool that benefits from point-of-use pressure control: sandblasters (adjusting blast intensity), airbrushes (fine detail work), air erasers, and detailing guns. The 0-160 PSI range covers virtually all pneumatic tool requirements.
