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.
